HSE SAFETY ALERT: REVISION OF STANDARDS FOR POWERED DOORS, GATES AND BARRIERS

The Health & Safety Executive have issued the following safety alert, aimed at architects/specifiers, designers, manufacturers, suppliers, and installers of powered doors, gates and barriers primarily for vehicular use, and those responsible for servicing and maintaining these products in workplaces, car parks and the common areas of shared premises, including residential:

KEY ISSUES

Publication of two newly revised European Standards on the safety of doors, gates and barriers – BS EN 12453:2017 and BS EN 12604:2017.

These new standards replace four older standards from 2000 and 2001; they represent a significant move forward. However, these standards do not completely address the risks that may be present and additional consideration should be given to the following aspects:

  • Undertaking a risk assessment covering the unique environment and type of user
  • The selection and implementation of appropriate design measures
  • Ensuring appropriate levels of force limitation (below the specified maximum)
  • Where the technology permits, ensuring that the safety function is monitored and checked before each movement; and
  • Ensuring effective measures are in place to detect any means of failure in the means of suspension for vertically moving doors. More detail is given below.

INTRODUCTION

  • British/European standards BS EN 12453:2017 concerning the safety requirements and tests for powered doors, gates and barriers primarily for vehicular use, and BS EN 12604:2017 concerning mechanical requirements and tests for the safety of both powered and non-powered versions of these products, have now been published. They are available for purchase online from BSI.
  • They replace and supersede in full the 2000/01 versions of these standards which dealt with the same products and issues; these two new standards cover what was previously dealt with in four standards (BS EN 12453, BS EN 12445, BS EN 12604 and BS EN 12605).
  • These new standards are a major step forward in helping to define the ‘state of the art’ for all products in scope, especially for the safety related parts of the control system on which these products depend for safety. They maintain the previous requirements for basic strength, stability and testing, including where force limitation is the primary means of delivering safety. The requirement on force limitation is not to exceed the existing force limits (basically 400 N for crushing and 1400 N for impact).
  • HSE’s view, however, is that there are aspects of the standards where they do not as yet fully meet the objectives of the Essential Health and Safety Requirements (EHSRs) of the European Machinery Directive 2006/42/EC. This means that compliance alone with the standards will not be enough to meet the requirements of the Supply of Machinery (Safety) Regulations 2008 (SMR08) for either new products placed on the market, or when first put into service (e.g. in situ manufacture, and powering existing gates).

BACKGROUND

  • Following two child fatalities which involved powered gates in 2010, HSE carried out a detailed examination of the suite of British/European standards then available to support the design and construction of powered doors, gates, barriers etc (see the related previous Safety Bulletins). HSE concluded that collectively the standards failed in a number of areas to adequately support the EHSRs of the Machinery Directive.
  • The Directive, which has been implemented into UK law for well over 20 years by SMR08, applies to all machinery, which includes powered doors, gates and barriers, when newly placed on the market, or when first put into service (eg when made in situ, or existing manual gates are ‘motorised’).
  • The UK launched its Formal Objectionto the standards in December 2010, as permitted by Article 10 of the Machinery Directive.
  • The European Commission considered the objection and agreed with the UK that the key standards did not entirely satisfy the EHSRs of the Machinery Directive. Its decision was confirmed and published by two Decisions which were made publicly available in 2015. Additionally, warnings were placed against the entries for EN 12635 and EN 13241-1 in the list of standards harmonised under the Machinery Directive in the official Journal of the European Union, in effect removing the ‘presumption of conformity’ that they previously gave.
  • Removing this presumption of conformity does not prevent manufacturers and installers of these products complying with the Directive/UK Regulations. Rather it means that manufacturers/installers who choose to use these standards can no longer simply rely on complying with the standards to meet all of the requirements of the Directive/UK Regulations.
  • Regulation 7(1) of SMR08 requires all machinery such as powered doors, gates and barriers to be safe. It is the duty of the person responsible for the design, construction and placing on the market/putting into service of the machinery to ensure this. Others then have the ongoing responsibility to keep the product safe through its lifetime of use, which includes ensuring non-employed persons are not endangered by the equipment (see below for link to FAQs).

ACTION REQUIRED

  • The new standards are not “harmonised”. This means that manufacturers (and installers, who often ‘put into service’ a new machine made in situ), must continue to show through a detailed technical file for each product how it has been designed and constructed to meet the safety objectives of the legislation. This must be undertaken before the CE marking is applied and the product is made available to the end user, together with comprehensive User/Maintenance Instructions, and a Declaration of Conformity, which must be made out in the name of the person responsible for the product’s conformity.
  • While these new revised standards can help define the ‘state of the art’ which must be reached, in all cases a thorough assessment of risk must be undertaken which fully considers the unique environment of use, the presence of and use by any vulnerable person, and all hazards arising from use, and foreseeable misuse, such as riding on the door or gate.
  • Design measures (to avoid risk, eg from hinge areas, collapse/falling over) and protective measures (guarding, fencing, safety edges, presence detection, etc) must be implemented during construction, taking into account the presence of any vulnerable populations such as children and those with reduced mobility or other disabilities, and any foreseeable misuse that may arise (such as playing on or near such equipment, or anyone rushing through gaps). You cannot rely on warnings alone to manage significant risks, although they may have their place in some circumstances.
  • Where force limitation is the primary means of safety, impact and crushing forces should be as low as possible (the standards give maximum levels), and verified by testing post installation.
  • Where the technology permits, the check of the safety function should take place before each movement. This is very important where vulnerable populations are at risk, as even one failure could result in serious or fatal injury from crush/entrapment.
  • Effective measures should be taken to detect any failure in the means of suspension of vertically moving doors, preferably stopping further use (unintended movement beyond 300 mm should be prevented), so that action can be taken before any catastrophic failure.
  • The existing harmonised standard BS EN 12978:2003+A1:2009 on safety devices for power operated doors and gates gives specific requirements to support the safe design of these products (Note: a revision of this standard is expected in 2019).
  • Although these standards are not intended for retrospective application, many existing powered doors, gates and barriers may not be as safe as they should be (some did not meet the previous standards or requirements for safety when originally supplied), so they can be used to support the re-assessment and any necessary upgrades to make existing products safer for continued use.
  • All readers are advised to consider the other available information and the existing Safety Bulletins published by HSE on these products (see below for links).

Letter from Melanie Dawes to owners, landlords and managers of private residential blocks about safety checks following the Grenfell Tower fire

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. If in the unlikely event any difficulties are experienced whilst registering we’ll be more than happy to help and can be contacted on 07896 016380 or at Fiona@eljay.co.uk

Melanie Dawes, Permanent Secretary at the Department of Communities and Local Government (DCLG), has written to owners, landlords and managers of private residential blocks about safety checks following the Grenfell Tower fire. The government is making available testing facilities for private owners of residential blocks that have cladding made of aluminium composite material, and the letter explains how to identify this cladding, and access the testing facilities.

The letter, and supporting documents, can be viewed by clicking on the following link: https://www.gov.uk/government/publications/safety-checks-on-private-residential-blocks and we have published the contents below. Queries should be directed to PRShousingchecks@communities.gsi.gov.uk, but if you require any general assistance regarding fire safety in blocks of flats, please don’t hesitate to contact us on 07896 016380 or at fiona@eljay.co.uk, and we’ll be happy to help.

Safety checks on private residential blocks

This letter is intended for owners, landlords and managers of private residential blocks in England. Representative bodies for the private residential sector have kindly agreed to disseminate this letter to their members, and we are grateful for their assistance.

Following the horrific fire at Grenfell Tower in North Kensington last week, we want to ensure you are aware of help that is available in checking your buildings.

There has been much public concern and comment about potential flaws in the cladding that was on Grenfell Tower. While the exact reasons for the speed of the spread of fire have yet to be determined, we have concluded that there are additional tests that can be undertaken with regard to the cladding. We have asked local authorities and social housing providers to identify whether any panels used in new build or refurbishment of their own housing stock are a particular type of cladding made of Aluminium Composite Material (ACM). These checks will be relevant to privately owned and managed residential buildings too, so please can you consider carrying out these checks on your buildings.

More details on how to identify this cladding are in Annex A below.  It is important to stress that ACM cladding is not of itself dangerous, but it is important that the right type is used. If you identify that cladding on any of your buildings is made of ACM, then a sample can be tested.

This testing facility is also being made available to blocks that are privately owned, and your local authority may already have been in touch to make you aware of this.  The procedures for taking up this offer of testing, which will be paid for by DCLG, are set out in the annex. We are prioritising buildings over six storeys or 18 metres high.  The offer is for the initial testing only and the cost of any remedial action will be the responsibility of the owner of the building. The information from the checks will be available to DCLG from BRE. Please contact us at PRShousingchecks@communities.gsi.gov.uk if you have any queries.

Where the entire block is not owned and managed by the same party, please ensure that only one sample is provided and that any necessary permissions are obtained for taking and sending off the sample. We would not expect individual leaseholders within a building to send off samples for testing.

As well as this work it is of course important that owners / landlords have robust fire assessments for their properties.

Thank you for your cooperation in this important work.

Annex A

Protocol for Sampling of Aluminium Composite Material Cladding

Identification of Aluminium Composite Material Cladding

Aluminium Composite Material (ACM) is a type of flat panel that consists of two thin aluminium sheets bonded to a non-aluminium core, typically between 3 and 7mm thick. The panels can have a painted or metallic finish (eg copper or zinc effects). It can be differentiated from solid aluminium sheet by looking at a cut edge whereby the lamination is visible. It may be necessary to cut a hole in a panel if a cut edge is not readily accessible.

On buildings with a floor over 18m above ground level, where ACM panels are identified, it is necessary to establish whether the panels are of a type that complies with the Building Regulations guidance ie the core material should be a material of limited combustibility or Class A2.

Testing of ACM

To allow for the identification of core materials, we are putting in place Government-funded testing capacity that will allow a small sample of the cladding to be tested and its type identified. If you wish to take up this offer, then you will need to submit samples for testing.

Where the surveyor undertaking assessment of a composite panel determines that it is necessary for cladding to be subjected to laboratory screening they should follow this procedure:

  1. Cut out two samples of at least 250x250mm in size from each location sampled. Take photographs as necessary to identify the location of the sample. You should take samples from above and below 18m above ground level as appropriate and check different multiple panels where you have concern that material specification varies.
  1. Using an indelible ink pen, note the building name / number, postcode and a unique identifier (i.e. name of building owner followed by unique sample number e.g. ABC/001) traceable to the specific location within the building of each sample. Add a direct dial telephone or mobile contact number to be used in the event that there are any queries on the sample.
  1. You must make good by closing the hole using a non-combustible sheet such as steel fixed with self-tapping screws or rivets.
  1. Complete the data return form attached to this letter (https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/620798/Data_Return_Form_for_testing_of_ACM_-_private_residential.xlsx) and include a hard copy of it with the sample. You should provide as much information as is readily available, but not if this will delay submission of samples for testing.
  1. Place one of the samples from each location in a padded envelope with a copy of the data return form. Clearly mark the envelope URGENT – CLADDING TEST SAMPLE.
  1. Send the test samples by recorded delivery or courier to:

BRE, Bucknalls Lane, Garston, Watford, Herts, WD25 9XX

For any testing related queries please email material.screening@bre.co.uk

  1. Retain the second sample from each location for your own records or for testing in the event that samples are lost or misplaced in transit
