GATE SAFETY Powered By Docstoc
					Power Operated Gates
All Power Operated Gate Installations, either domestic or
commercial, must, by law under the Machinery Directive, be

The Machinery Directive has been in place since 1995 but is now
updated to the Supply of Machinery (Safety) Regulations 2008
which came into force 29/12/2009

It is the responsibility of the installer to ensure the installation is compliant with the
Machinery Directive.

How can the installer comply with the Machinery Directive?

    1)   Risk assessment
    2)   Careful design and construction
    3)   Inclusion of Safety Devices
    4)   Force Testing
    5)   Technical File
    6)   CE Marking and Declaration of Conformity
    7)   User Instructions
    8)   Servicing

UK Gates can offer advice and guidance on complying with the Machinery

Questions and Answers

Q        Do the rules only apply to a new gate installation?
A        No they also apply when you retrofit a motor

Q        Do I have to force test every gate
A        Yes – to ensure it does not exceed the maximum force as required by the

Q        What is CE Marking and do I have to do it
A        In order to CE mark, you must complete a technical file, issue a Declaration of
         Conformity and apply a CE Label to the installation; yes you must now do this
         for every installation

Q        What if I just replace a like for like motor
A        Yes testing after installing the new motor is still required

Q        What if I am repairing an older installation
A        You must do a risk assessment and make your recommendations for bringing
         the installation in line with current safety standards; you should leave the gate in
         a safe condition, which may mean switching off the power

Q        Do all the above apply to domestic installations
A        Yes

Q        Are there other regulations that relate to commercial installations
A        As well as the Machinery Directive, The Health and Safety at Work Act 1974,
         The Management of Health and Safety at Work Regulations 199 and
         The Provision & Use of Work Equipment Regulations 1998 (PUWER 98)
Installer Guidance for a Safe Installation

1) Risk Assessment – to identify hazards and associated risks to all persons using the gate,
including the possibility of misuse.
Risks associated with power operated gates fall into one of three categories,
Crushing, Shearing and Drawing-In (or trapping).

Crushing - this could be where any two gaps will be continually reduced until such a point
where the gap is eliminated. Typical examples being where a sliding gate is closing against a
fixed post or hinged gates are opening back against a post or wall

Shearing – This could be where a gap would vary when in motion causing an entrapment
zone. Typically examples being where a railed sliding gate moves past a post and therefore
anyone putting an arm through the gate would risk injury from the shearing force exerted or
where two hinged gates close together the point where they meet would again create a
shearing point

Drawing-in – This could be either where sliding gates move through a portal frame, or on
swing gates where the space around hinge areas can reduce in size when the gate opens or

New Installations – carry out a risk assessment to identify hazards and risks to all persons
using the gate.
Repairs or Servicing to existing installations – the same risk assessment should be carried
out, and any recommendations made to bring the installation in line with current standards of
safety. This should be done in writing and a copy kept. The gate should be left in a safe
condition, this may mean, switching off the power supply, or making the gates inoperable.

The standards and procedures for risk assessments are contained in our information sheet
“A Guide to Risk Assessment”

2) Careful Design and Construction – to minimise the risks identified

This will include:
physical measures such as, enclosing the area in which the gate moves to prevent access,
and the fixing of mesh protection to the gate, eliminating gaps larger than 100mm.

the use of motors with force limitation which conform to EN12453

the inclusion of safety edges and photocells ( safety edges should comply with EN 12978 and
EN1760-2 )

It is the view of the HSE that photocells on their own do not provide sufficient protection, and a
combination of force limitation, and pressure sensitive safety edges are more effective in
providing a safe gate installation.

3) Force Testing – There are maximum permissible forces laid down in Annex A of BS EN
12453:2001 which must be measured in accordance with BS EN12445:2001
Without the correct equipment it is not possible to do this and an installer cannot effect a safe
and legal installation

4) Technical File – this must contain drawings of the installation, the risk assessment, the
force test results, copies of certificates of incorporation, and the installers Declaration of

 5) User Instructions – upon handover the client should be given instruction in the use of the
gate, including the manual release device, a copy of the user instructions should be left with

 6) Servicing – regular servicing is required to ensure the correct operation of safety devices,
force testing should be included in the servicing schedule to ensure the force exerted remains
within the required limits.
