Scaffold checklist – company fined after scaffolding blown over during dismantling

Construction hazardous substances: Cement – construction firm fined after worker suffers cement burns

Preventing exposure to carbon monoxide from use of solid fuel appliances in commercial kitchens

Introduction

This is our last news update of the year and we would like to take this opportunity to wish all of our readers Merry Christmas and a Happy New Year.

As we head into winter, the cold temperatures predicted have thankfully so far eluded us, but heavy rain and strong winds are, worryingly, becoming commonplace. Only last weekend, outside a North Staffordshire convenience store, a 40 metre stretch of scaffolding blew down, landing on six parked cars. Amazingly and luckily, nobody was hurt. And this week, a scaffolding company was fined after scaffolding they were dismantling blew over and hit a bus and pedestrians. Investigation by the HSE found that the scaffolding was not tied to the building, and sheeting was left in place. We open this week’s update with HSE guidance intended to clarify when a scaffold design is required and what level of training and competence those erecting, dismantling, altering, inspecting and supervising scaffolding operations are expected to have.

Staying with construction, we also share HSE guidance on controlling the risks of serious skin problems such as dermatitis and burns which can arise from using cement based products, like concrete or mortar. This is after a construction firm was fined £14,000 plus £1590 costs when a 54-year-old employee suffered severe cement burns to his knees while laying concrete flooring.

Finally, with the increasing popularity of charcoal and wood-fired ovens, the uptake of solid fuel appliances in restaurant kitchens has been rapid. But the Health Protection Agency has warned that wood burning stoves “can cause lethal carbon monoxide poisoning”. So the HSE have published a new catering information sheet which we share this week, aimed specifically at employers who use solid fuel appliances such as tandoori ovens, charcoal grills and wood-fired pizza ovens in commercial kitchens.

We hope you find our news updates useful. If you know of anyone who may benefit from reading them, please encourage them to register at the bottom-left of our news page (http://www.eljay.co.uk/news/) and we’ll email them a link each time an update is published.

Scaffold checklist – company fined after scaffolding blown over during dismantling

A scaffolding company has been fined a total of £8,000 plus £2,000 costs after scaffolding hit a bus and pedestrians when it blew over during dismantling.

Leicester Magistrates’ Court heard how in January 2015 the company was dismantling scaffolding on a city centre street when the incident occurred. The scaffolding hit a bus, landed on a parked van and hit two members of the public.

An investigation by the Health and Safety Executive (HSE) into the incident, found that the company was not following a safe system of work. The scaffolding was not tied to the building and sheeting was left in place. The scaffolding dismantling took place over four days and the workers failed to check the scaffolding condition before they started or to take adequate measures to correct defects and ensure it would not collapse during the dismantling.

Speaking after the hearing HSE inspector Martin Giles said: “Scaffolding needs to be tied to a building and dismantling needs to be properly planned and carried out in a safe manner.”

Scaffold checklist

This guide is intended to clarify when a scaffold design is required and what level of training and competence those erecting, dismantling, altering, inspecting and supervising scaffolding operations are expected to have.

Scaffold design

It is a requirement of the Work at Height Regulations 2005 that unless a scaffold is assembled to a generally recognised standard configuration, eg NASC Technical Guidance TG20 for tube and fitting scaffolds or similar guidance from manufacturers of system scaffolds, the scaffold should be designed by bespoke calculation, by a competent person, to ensure it will have adequate strength, rigidity and stability while it is erected, used and dismantled.

At the start of the planning process, the user should supply relevant information to the scaffold contractor to ensure an accurate and proper design process is followed.  Typically this information should include:

  • site location
  • period of time the scaffold is required to be in place
  • intended use
  • height and length and any critical dimensions which may affect the scaffold
  • number of boarded lifts
  • maximum working loads to be imposed and maximum number of people using the scaffold at any one time
  • type of access onto the scaffold eg staircase, ladder bay, external ladders
  • whether there is a requirement for sheeting, netting or brickguards
  • any specific requirements or provisions eg pedestrian walkway, restriction on tie locations, inclusion/provision for mechanical handling plant eg hoist)
  • nature of the ground conditions or supporting structure
  • information on the structure/building the scaffold will be erected against together with any relevant dimensions and drawings
  • any restrictions that may affect the erection, alteration or dismantling process

Prior to installation, the scaffold contractor or scaffold designer can then provide relevant information about the scaffold.  This should include:

  • type of scaffold required (tube & fitting or system)
  • maximum bay lengths
  • maximum lift heights
  • platform boarding arrangement (ie 5 + 2) and the number of boarded lifts that can be used at any one time
  • safe working load / load class
  • maximum leg loads
  • maximum tie spacing both horizontal and vertical and tie duty
  • details of additional elements such as beamed bridges, fans, loading bays etc, which may be a standard configuration (see note 1 ref TG20:13) or specifically designed
  • information can be included in relevant drawings if appropriate
  • any other information relevant to the design, installation or use of the scaffold
  • reference number, date etc. to enable recording, referencing and checking

All scaffolding must be erected, dismantled and altered in a safe manner.  This is achieved by following the guidance provided by the NASC in document SG4 ‘Preventing falls in scaffolding’ for tube and fitting scaffolds or by following similar guidance provided by the manufacturers of system scaffolding.

For scaffolds that fall outside the scope of a generally recognised standard configuration the design must be such that safe erection and dismantling techniques can also be employed throughout the duration of the works. To ensure stability for more complex scaffolds, drawings should be produced and, where necessary, these may need to be supplemented with specific instructions.

Any proposed modification or alteration that takes a scaffold outside the scope of a generally recognised standard configuration should be designed by a competent person and proven by calculation.

Scaffold structures that normally require bespoke design

Includes:

  • all shoring scaffolds (dead, raking, flying)
  • cantilevered scaffolds
  • truss-out Scaffolds
  • façade retention
  • access scaffolds with more than the 2 working lifts
  • buttressed free-standing scaffolds
  • temporary roofs and temporary buildings
  • support scaffolds
  • complex loading bays
  • mobile and static towers
  • free standing scaffolds
  • temporary ramps and elevated roadways
  • staircases and fire escapes (unless covered by manufacturers instructions)
  • spectator terraces and seating stands
  • bridge scaffolds
  • towers requiring guys or ground anchors
  • offshore scaffolds
  • pedestrian footbridges or walkways
  • slung and suspended scaffolds
  • protection fans
  • pavement gantries
  • marine scaffolds
  • boiler scaffolds
  • power line crossings
  • lifting gantries and towers
  • steeple scaffolds
  • radial / splayed scaffolds on contoured facades
  • system scaffolds outside manufacturers guidance
  • sign board supports
  • sealing end structures (such as temporary screens)
  • temporary storage on site
  • masts, lighting towers and transmission towers
  • advertising hoardings/banners
  • rubbish chute
  • any scaffold structure not mentioned above that falls outside the ‘compliant scaffold’ criteria in TG20 or similar guidance from manufacturers of system scaffolds.

The above list is not exhaustive and any scaffold that is not a standard configuration or does not comply with published manufacturers’ guidelines will require a specific design produced by a competent person.

Note:

  1. TG20:13 provides compliant scaffolds for a limited range of cantilever scaffolds, loading bays, static towers, use of rakers, bridges and protection fans.
  1. TG20:13 provides a range of compliant scaffolds, which can be boarded at any number of lifts, but only two platforms can be used as working platforms at any one time.

Competence and supervision of scaffolding operatives

All employees should be competent for the type of scaffolding work they are undertaking and should have received appropriate training relevant to the type and complexity of scaffolding they are working on.

Employers must provide appropriate levels of supervision taking into account the complexity of the work and the levels of training and competence of the scaffolders involved.

As a minimum requirement, every scaffold gang should contain a competent scaffolder who has received training for the type and complexity of the scaffold to be erected, altered or dismantled.

Trainee scaffolders should always work under the direct supervision of a trained and competent scaffolder. Operatives are classed as ‘trainees’ until they have completed the approved training and assessment required to be deemed competent.

Erection, alteration and dismantling of all scaffolding structures (basic or complex) should be done under the direct supervision of a competent person. For complex structures this would usually be an ‘Advanced Scaffolder’ or an individual who has received training in a specific type of system scaffold for the complexity of the configuration involved.

Scaffolding operatives should be up to date with the latest changes to safety guidance and good working practices within the scaffolding industry. Giving operatives job specific pre-start briefings and regular toolbox talks is a good way of keeping them informed.

Guidance on the relevant expertise of Scaffolders and Advanced scaffolders including details of which structures they are deemed competent to erect can be obtained from the Construction Industry Scaffolders Record Scheme (CISRS) website (http://cisrs.org.uk/).

Scaffold inspection

It is the scaffold users / hirers responsibility to ensure that all scaffolding has been inspected as follows:

  • following installation / before first use
  • at an interval of no more than every 7 days thereafter
  • following any circumstances liable to jeopardise the safety of the installation eg high winds.

All scaffolding inspection should be carried out by a competent person whose combination of knowledge, training and experience is appropriate for the type and complexity of the scaffold.

Competence may have been assessed under the CISRS or an individual may have received training in inspecting a specific type of system scaffold from a manufacturer/supplier.

A non-scaffolder who has attended a scaffold inspection course (eg a site manager) could be deemed competent to inspect a basic scaffold structure.

The scaffold inspection report should note any defects or matters that could give rise to a risk to health and safety and any corrective actions taken, even when those actions are taken promptly, as this assists with the identification of any recurring problem.

Construction hazardous substances: Cement – construction firm fined after worker suffers cement burns

A construction firm has been fined £14,000 plus £1590 costs after a 54-year-old employee suffered severe cement burns to his knees while laying concrete flooring.

Sefton Magistrates’ Court heard that in November 2014, the employee kneeled in wet concrete to manually finish the concrete flooring being laid in a domestic bungalow. The cement burns to both his knees resulted in 12 days hospitalisation and ongoing treatment.

The Health and Safety Executive (HSE) investigation found the firm failed to adequately assess the risks and implement suitable and sufficient control measures to protect employees from contact of the wet concrete with the skin. In addition, it did not provide suitable Personal Protective Equipment (PPE) and there were no welfare facilities on site.

The court heard the company had been served with HSE Improvement Notices for lack of welfare facilities in September 2014 and June 2014.

HSE inspector Anne Foster said after the hearing: “The injuries the employee suffered were entirely foreseeable and avoidable had the company implemented suitable controls, such as the use of long-handled tools, or the provision of suitable chemical resistant PPE. It is also wholly unreasonable to expect workers to travel four miles to find welfare facilities.”

What you must do

The Control of Substances Hazardous to Health (COSHH) Regulations (http://www.hse.gov.uk/coshh/index.htm) says you must protect against the risks from cement-based products. Follow the Assess, Control and Review model. Pay particular attention to:

Assess

Identify and assess: Identify those tasks where cement based products will be used. Workers handling / mixing cement powder or using wet mortar and cement are particularly at risk. Check for any existing skin or allergy problems as this work could make these conditions worse. Follow the control steps below.

Cement powder is also a respiratory irritant. The dust produced while cutting, drilling etc dried concrete and mortar can cause more serious lung disease. More information on assessing and controlling this risk can be found in the section on construction dust (http://www.hse.gov.uk/construction/healthrisks/hazardous-substances/construction-dust.htm).

Control

Prevent: Where possible think about eliminating or reducing the amount of cement used and contact with it. Consider:

  • avoiding exposure to cement powder by using pre-mixed concrete / mortar
  • using work methods that increases the distance between the worker and the substance such as longer handled tools
  • rotating cement bags to ensure they are used before the shelf date. The ingredient added to reduce the risk of allergic contact dermatitis is only effective for a limited period.

Control: Even if you stop some of the risk this way, you may still do other work that might involve contact with cement. Control the risk by:

  • Gloves – gloves should be waterproof and suitable for use with high pH (alkaline) substances; eg marked with EN374:2003 and tested for use with “alkalis and bases” (class K) – some nitrile or PVC gloves may be suitable. Breakthrough time and permeation rate should also be suitable for the type and duration of the work. Gloves should be long and /or tight fitting at the end to prevent cement being trapped between the glove and the skin.
  • More information on gloves: http://www.hse.gov.uk/skin/employ/gloves.htm
  • Footwear – suitable footwear, such as wellington boots, should be used where large concrete pours are taking place. If standing in cement, these should be high enough to prevent cement entering the top of the boot.
  • Waterproof trousers – when kneeling on wet products containing cement, appropriate waterproof trousers should be worn or, if screeding, use appropriate waterproof knee pads or knee boards. Minimise any time spent kneeling. Wear trousers over the top of boots. This stops cement getting into them.
  • Washing – wash off any cement on the skin as soon as possible. Workers should be encouraged to wash exposed skin at breaks and after work. Good washing facilities are essential. There should be hot and cold or warm running water, soap and towels. Basins should be large enough to wash forearms. Showers may be needed in some situations where workers could get heavily covered in cement. Use emergency eyewash to remove any cement that gets into eyes.
  • Skin care products – these can help to protect the skin. They replace the natural oils that help keep the skin’s protective barrier working properly.

Train: Workers need to know how to use the controls properly. They also need to be aware of the signs and symptoms of dermatitis.  Finding skin problems early can stop them from getting too bad.

Review

Supervise: Ensure that controls such as work methods, PPE and welfare are effective and used by the workers.

Monitor: Appropriate health surveillance is needed to check your controls are preventing dermatitis. This could be done by a ‘responsible person’ who can be an employee provided with suitable training. They should:

  • assess the condition of a new worker’s skin before, or as soon as possible after, they start work and then periodically check for early signs of skin disease after this
  • keep secure health records of these checks
  • tell the employer the outcome of these checks and any action needed

What you should know

Skin problems are not just a nuisance, they can be very painful and sometimes debilitating. Cement and cement-based products can harm the skin in a number of ways.

Wet cement is highly alkaline in nature. A serious burn or ulcer can rapidly develop if it is trapped against the skin. In extreme cases, these burns may need a skin graft or cause a limb to be amputated. Cement can also cause chemical burns to the eyes.

Cement also causes dermatitis. It can abrade the skin and cause irritant contact dermatitis. Cement also contains hexavalent chromium (chromate). This can cause allergic contact dermatitis due to sensitisation. Manufacturers add an ingredient to lower the hexavalent chromium content and reduce this risk. This ingredient is only effective for a limited period as indicated by the shelf date. After this period, the level of hexavalent chromium may increase again. Once a person has become sensitised to this substance, any future exposure may trigger dermatitis. Some skilled tradesmen have been forced to change their trade because of this.

Preventing exposure to carbon monoxide from use of solid fuel appliances in commercial kitchens

This new catering information sheet is published in collaboration with the Heating Equipment Testing and Approval Scheme, the Solid Fuel Association and the Hospitality Industry Liaison Forum.

The guidance is aimed specifically at employers who use solid fuel appliances such as tandoori ovens, charcoal grills and wood-fired pizza ovens in commercial kitchens. It is concerned with the risks of exposure to carbon monoxide gas for workers as well as members of the public and outlines how they can be protected and what the law says.

Introduction

Legionella and Legionnaires’ disease – coatings firm in court for legionella failings

Solder fume and you – an employee’s guide

3M SafeTea Break 2015 Campaign

Introduction

Legionnaires’ disease is, unfortunately, in the news regularly. Only last month a driving test centre in Kent had to be shut down after the bacteria – which can cause the potentially fatal lung infection – was found during a routine water test. One of the worst outbreaks in UK history was in 2002 in Barrow-in-Furness, the source of which was an arts centre air conditioning unit. 172 cases of the disease were reported, resulting in seven deaths. If you are an employer, or someone in control of premises, including landlords, you must understand the health risks associated with legionella, and take the right precautions to reduce the risks of exposure to the bacteria, guidance on which we share below. Failure to do so recently resulted in an international engineering firm being fined at total of £110,000 plus £77,252 costs.

If you work in an electronics, metalwork or plumbing related industry, you’re probably familiar with soldering processes, and the fact that serious health problems can arise from rosin, which is contained in solder fluxes. This week we share the HSE’s recently revised guidance document ‘Solder fume and you’ (INDG248) which gives advice to employees on safe working whilst soldering with rosin (colophony) based solder fluxes.

And finally, we share details of 3M’s SafeTea Break 2015 campaign which encourages employers to deliver bite-size ‘tea break’ talks to engage their workforces in discussions about health and long latency occupational diseases.

We hope you find our news updates useful. If you know of anyone who may benefit from reading them, please encourage them to register at the bottom-left of our news page (http://www.eljay.co.uk/news/) and we’ll email them a link each time an update is published.

Legionella and Legionnaires’ disease – coatings firm in court for legionella failings

An international engineering firm, which refurbishes turbine blades, was recently fined a total of £110,000 plus £77,252 costs for failing to manage the risk to public and employees to potentially fatal legionella bacteria.

The company, which has sites in Nottinghamshire and Derbyshire, failed to properly manage the risk of bacteria growing in their cooling towers for over a year, from May 2011.

Derby Crown Court heard that during a visit to one of the sites in May 2012, a Health and Safety Executive (HSE) inspector felt spray on his face, saw the yard’s surface was wet and that nearby cooling towers were corroded.

Corrosion can encourage the growth of legionella bacteria which is carried in water droplets. If water is inhaled which contains the bacteria, it can lead to a number of diseases, but most commonly legionnaire’s disease, a potentially fatal form of pneumonia.

The inspector extended his visit to the rest of the factory plus the company’s other site, and found significant failings in the company’s control, recording and management of legionella risks.

HSE issued four improvement notices in June 2012 requiring inlet screens to be placed on the cooling towers to stop debris falling in them which could encourage legionella growth, and for corroded items of plant to be replaced.

Two similar notices were served on the company in 2008 seeking improvements on rusting towers and a number of management failures. All the notices had been complied with.

The court was told a laboratory analysis of a water sample taken from one of the sites before the HSE investigation had found legionella bacteria levels to be so high that immediate action was required to clean the system.

As well as failing to maintain its infrastructure, the company did not keep biocides (chemicals which kill bacteria) at effective levels.

What is Legionnaires’ disease?

Legionellosis is a collective term for diseases caused by legionella bacteria including the most serious Legionnaires’ disease, as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever. Legionnaires’ disease is a potentially fatal form of pneumonia and everyone is susceptible to infection. The risk increases with age but some people are at higher risk including:

  • people over 45 years of age
  • smokers and heavy drinkers
  • people suffering from chronic respiratory or kidney disease
  • diabetes, lung and heart disease
  • anyone with an impaired immune system

The bacterium Legionella pneumophila and related bacteria are common in natural water sources such as rivers, lakes and reservoirs, but usually in low numbers. They may also be found in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold water systems and spa pools.

If conditions are favourable, the bacteria may grow increasing the risks of Legionnaires’ disease and it is therefore important to control the risks by introducing appropriate measures outlined in Legionnaires’ disease – The Control of Legionella bacteria in water systems (L8) (http://www.hse.gov.uk/pubns/books/l8.htm).

What you must do

If you are an employer, or someone in control of premises, including landlords, you must understand the health risks associated with legionella. This section can help you to control any risks.

Duties under the Health and Safety at Work etc Act 1974 (HSWA) extend to risks from legionella bacteria, which may arise from work activities. The Management of Health and Safety at Work Regulations (MHSWR) provide a broad framework for controlling health and safety at work.  More specifically, the Control of Substances Hazardous to Health Regulations 2002 (COSHH) provide a framework of actions designed to assess, prevent or control the risk from bacteria like Legionella and take suitable precautions.  The Approved Code of Practice: Legionnaires’ disease: The control of Legionella bacteria in water systems (L8) contains practical guidance on how to manage and control the risks in your system.

As an employer, or a person in control of the premises, you are responsible for health and safety and need to take the right precautions to reduce the risks of exposure to legionella. You must understand how to:

  • identify and assess sources of risk
  • manage any risks
  • prevent or control any risks
  • keep and maintain the correct records
  • carry out any other duties you may have

Identify and assess sources of risk

Carrying out a risk assessment is your responsibility. You may be competent to carry out the assessment yourself but, if not, you should call on help and advice from either within your own organisation or from outside sources, e.g. consultancies.

You or the person responsible for managing risks, need to understand your water systems, the equipment associated with the system such as pumps, heat exchangers, showers etc, and its constituent parts. Identify whether they are likely to create a risk from exposure to legionella, and whether:

  • the water temperature in all or some parts of the system is between 20–45 °C
  • water is stored or re-circulated as part of your system
  • there are sources of nutrients such as rust, sludge, scale, organic matter and biofilms
  • the conditions are likely to encourage bacteria to multiply
  • it is possible for water droplets to be produced and, if so, whether they can be dispersed over a wide area, e.g. showers and aerosols from cooling towers
  • it is likely that any of your employees, residents, visitors etc are more susceptible to infection due to age, illness, a weakened immune system etc and whether they could be exposed to any contaminated water droplets

Your risk assessment should include:

  • management responsibilities, including the name of the competent person and a description of your system
  • competence and training of key personnel
  • any identified potential risk sources
  • any means of preventing the risk or controls in place to control risks
  • monitoring, inspection and maintenance procedures
  • records of the monitoring results and inspection and checks carried out
  • arrangements to review the risk assessment regularly, particularly when there is reason to suspect it is no longer valid

If you conclude that there is no reasonably foreseeable risk or the risks are low and are being properly managed to comply with the law, your assessment is complete. You may not need to take any further action at this stage, but any existing controls must be maintained and the assessment reviewed regularly in case anything changes in your system.

Managing the risk

As an employer, or person in control of premises, you must appoint someone competent to help you meet your health and safety duties and to take responsibility for controlling any identified risk from exposure to legionella bacteria. A competent person, often known as the responsible person, is someone with sufficient authority, competence, necessary skills, knowledge of the system, and experience. The appointed responsible person could be one, or a combination of:

  • yourself
  • one or more workers
  • someone from outside your business

If there are several people responsible for managing risks, e.g. because of shift-work patterns, you must make sure that everyone knows what they are responsible for and how they fit into the overall risk management of the system.

If you decide to employ contractors to carry out water treatment or other work, it is still the responsibility of the competent person to ensure that the treatment is carried out to the required standards. Remember, before you employ a contractor, you should be satisfied that they can do the work you want to the standard that you require. There are a number of external schemes to help you with this, for example, A Code of Conduct for service providers (http://www.legionellacontrol.org.uk/). The British Standards Institute have published a standard for legionella risk assessment (http://shop.bsigroup.com/ProductDetail/?pid=000000000030200235)

Preventing or controlling the risk

You should first consider whether you can prevent the risk of legionella by looking at the type of water system you need, e.g. identify whether it is possible to replace a wet cooling tower with a dry air-cooled system. The key point is to design, maintain and operate your water services under conditions that prevent or adequately control the growth and multiplication of legionella.

If you identify a risk that you are unable to prevent, you must introduce a course of action ie a written control scheme, that will help you to manage the risk from legionella by implementing effective control measures, by describing:

  • your system, e.g. develop a schematic diagram
  • who is responsible for carrying out the assessment and managing its implementation
  • the safe and correct operation of your system
  • what control methods and other precautions you will be using
  • what checks will be carried out, and how often will they be carried out, to ensure the controls remain effective

You should:

  • ensure that the release of water spray is properly controlled
  • avoid water temperatures and conditions that favour the growth of legionella and other micro-organisms
  • ensure water cannot stagnate anywhere in the system by keeping pipe lengths as short as possible or removing redundant pipework
  • avoid materials that encourage the growth of legionella (The Water Fittings & Materials Directory (http://www.materialstesting.co.uk/materials_directory.htm) references fittings, materials, and appliances approved for use on the UK Water Supply System by the Water Regulations Advisory Scheme)
  • keep the system and the water in it clean
  • treat water to either control the growth of legionella (and other microorganisms) or limit their ability to grow
  • monitor any control measures applied
  • keep records of these and other actions taken, such as maintenance or repair work

Keeping records

If you have five or more employees you have to record any significant findings, including those  identified as being particularly at risk and the steps taken to prevent or control risks.  If you have less than five employees, you do not need to write anything down, although it is useful to keep a written record of what you have done.

Records should include details of the:

  • person or persons responsible for conducting the risk assessment, managing, and implementing the written scheme
  • significant findings of the risk assessment
  • written control scheme and details of its implementation
  • details of the state of operation of the system, i.e. in use/not in use
  • results of any monitoring inspection, test or check carried out, and the dates

These records should be retained throughout the period for which they remain current and for at least two years after that period. Records kept in accordance with (e) should be retained for at least five years.

Other duties

Under the Notification of Cooling Towers and Evaporative Condensers Regulations 1992, you must notify your local authority in writing, if you have a cooling tower or evaporative condenser on site, and include details about where it is located. You must also tell them if/when such devices are no longer in use. Notification forms are available from your local authority/environmental health department.

Although less common, other systems that do not rely solely on the principle of evaporation, are dry/wet coolers or condensers. Owing to their different principles of operation, these systems may not require notification under the Notification of Cooling Towers and Evaporative Condensers Regulations 1992 (NCTEC) but it is important to assess the system against the notification requirements defined in NCTEC, eg where such systems spray water directly onto the surface of the heat exchanger.

In addition, under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR), you must report any cases of legionellosis in an employee who has worked on cooling towers or hot and cold water systems that are likely to be contaminated with legionella.

Specific risk systems

You will also need to consider technical and further information on the following risk systems (click on the links):

We carry out Legionnella Risk Assessments of hot and cold water systems in commercial and residential property and can provide further information on request.

Solder fume and you – an employee’s guide

This guidance is aimed at people who solder using rosin, specifically colophony-based solder flux, which can cause asthma and dermatitis.

Be aware:

  • Working with rosin-based solder fluxes requires you to take action. You should take appropriate steps to prevent, control or reduce exposure to fumes, as they can cause serious health problems.
  • There are different types of solder flux. Find out from your manager what type of solder fume you are using.

Remember:

  • Serious health problems can occur when soldering.
  • Report symptoms of ill health to your manager. These can include: coughing; wheezing; runny eyes or nose; tight chest. These can all be symptoms of occupational asthma or serious illness.
  • If solder flux fume makes you ill, the effects will become worse if you carry on breathing in the fume.
  • Where it is necessary to have a health surveillance process in place to help protect the health of employees, your employer will ask you to co-operate.

To protect your health:

  • Keep your face out of the solder fume.
  • Use the correct control measure(s), such as: local exhaust ventilation (LEV); solder fume extraction; on-tip extraction; down-draught benches; enclosing hoods; moveable capturing hoods. Look at Controlling health risks from rosin (colophony)-based solder fluxes (see Further reading) for further information on which method you should use.
  • Use fume extraction when you are either: – soldering using rosin-based fluxes; or – using alternative fluxes for more than a few minutes a day.
  • You should check that the system works properly every time you use or move it.
  • Check for yourself to see how effective the LEV is where you work.

3M SafeTea Break 2015 Campaign

3M in conjunction with Safety Groups UK have launched SafeTea Break 2015 Campaign. The campaign has an accompanying toolkit for bite-size ‘tea break’ talks to engage your workforce in discussions about health and long latency occupational diseases.

The kit provides open questions to present to the workforce in a breakout session that will generate debate across health topics, ultimately driving a useful action plan, and a better understanding of the health risks and consequences of non-compliance for the workforce.

Visit the website at http://safetynetwork.3m.com/blog/safetea/?WT.mc_id=www.3m.co.uk/SafeTea?ebul=gd-welding&cr=11/Dec15 where you can download the SafeTea Break pack for free.
