Definitions
3.9 deck-riding
practice of placing a MEWP on a previously erected structure above the ground prior to structural completion, either by using a static “sled” fixed to the base of the MEWP or by placing the MEWP on a temporary MEWP support frame
3.28 primary guarding
function enable device which requires activation prior to any lift or drive movement control being activated
NOTE Examples include a foot pedal, a recessed hold-to-run button or trigger.
3.32 secondary guarding
device fitted to a MEWP in addition to the primary guarding systems, to further reduce the risk of entrapment and/or provide an alert that an entrapment situation has occurred
NOTE Shrouds placed over the controls are not considered as secondary guarding
Definitions
3.41 user
person or organization that has control of the planning, management and use of the MEWP on site and is responsible for ensuring the MEWP is kept in a safe working condition
NOTE 1 This can include the person responsible for the site, principal contractor or subcontractor.
NOTE 2 This is not necessarily the same as the operator (see 3.22).
3.23 oscillating axle – definition enhanced
3.23.1 active oscillating axle
3.23.2 passive oscillating axle
Enhanced Risk assessment tables
Positioning prior to carrying out work
Setting up
During use
Thorough examination (including testing)
Maintenance
Loading and unloading transport vehicles
a well-lit area for loading activity to take place of sufficient size; on firm and level ground; segregated from other work activities; free of traffic, pedestrians and members of the
public where possible; clear of overhead and underground hazards
User responsible for providing On the public highway
Avoided where reasonably practicable Schedule deliveries for a quiet time Identify where the delivery vehicle will park Direction of vehicle for increased visibility Competent and authorized
supervisor/signaller Vehicle and pedestrian management MEWP is suitably restrained using appropriate load restraint devices
Secure…….slew pins to prevent booms accidentally slewing ..extending decks to prevent sliding out ..canopy doors to prevent opening
Modifications and or fitting additional devices or equipment
Annex D - Machine modifications and CE marking
Interchangeable equipment
a) installed by the operator;
b) after machine is put into service;
c) changes the function of the machine or
attributes a new function to the machine;
d) not a tool.
Responsibility
Original MEWP manufacturer is not liable for the adaptation, addition or modification or any effects it has on the safety and performance of the MEWP.
The person carrying out the adaptation, addition or modification takes on these responsibilities and may become liable for the safety of the complete MEWP.
Evidence recorded
Self familiarisation
Operator is confident in his ability Adequate time Safe location All relevant information available -Manual
Manufacturer's instructions and warnings
Features of the specific model
Control functions
Safety devices and Emergency lowering procedures
Previous experience Complexity Capacity
Authorised by User
Example of a rescue plan hierarchy
1 - Upper Primary controls 2 - Upper Auxiliary controls 3 - Ground Primary controls 4 - Ground Auxiliary controls 5 – Mid air rescue – (Annex B)
Trapping or crushing of persons in work platform
Preventative measures:
• correct planning and preparation
• selection of an appropriate MEWP
• trained operator and
• safe use
Operator and nominated rescue personnel familiarisation: functionality how it is triggered operated and reset Included in pre-use checks
The fitting and use of any additional device intended to further
reduce the risk of entrapment and/or provide an alert that an
entrapment situation has occurred, should not replace the
operator’s responsibility to be aware of their surroundings and
the need to follow safe working practice and protocols, but should be additional to those fundamental requirements
Secondary guarding
Secondary Guarding Concept for scissor platforms and vertical lifts
Some industry groups have recently suggested the possibility of certain circumstances, conditions and operations that might result in inadvertent contact with obstructions and a consequent entrapment hazard.
As a result, a form of “secondary guarding” is now being requested on scissor platforms and vertical lifts by some equipment users
Robust control box shroud provides additional guarding of controls reducing the risk of unintended actuation
Secondary “enable” button with an anti-tamper feature
Both primary and secondary “enables” must be activated to allow lift, the release of either will stop the function immediately
Having “dual enables” for lifting, significantly reduces the risk of crushing due to sustained inadvertent operation
The secondary “enable” button is not used for lowering the platform
Drive continues to use the joystick enable only
Does not limit or restrict operation during use
Working near electricity
GENERAL EXCLUSION ZONE – 9 and 15 metres
Working safely inside the general exclusion zone
2005 - MINIMUM SAFE DISTANCE
Standoff distance
Warning devices and slew restrictors Emergency procedures

Summary – BS 8460
Important status and purpose
The access industry has developed significantly in last 12 years
Significant aspects of safe use that were not addressed in the 2005 standard
Compiled by a cross section of experts from across the industry
The revision uses current guidance to enhance any recommendations
