MEWP RAMS Guide for UK Contractors

Key Topics in a MEWP RAMS

IPAF competence and MEWP categories

MEWP operators should hold a current IPAF (International Powered Access Federation) PAL card at the appropriate category for the machine being used. MEWP categories include: 1a (vehicle-mounted boom, restricted), 1b (vehicle-mounted boom, unrestricted), 3a (push-around self-propelled vertical), 3b (self-propelled boom). The RAMS must specify the MEWP category required, confirm that operators are IPAF carded for that category, and include reference to the manufacturer's pre-use inspection checklist.

Ground conditions and outrigger assessment

MEWP stability depends critically on ground conditions. The RAMS must require ground bearing capacity assessment before positioning any outrigger-stabilised MEWP, specification of outrigger pads where required, and prohibition of use on gradients exceeding the manufacturer's specification. Indoor MEWPs on mezzanine floors or elevated slabs must have structural confirmation that the slab can carry the MEWP point loads.

Overhead hazards — electrical power lines

Overhead electrical power lines are a major hazard for boom-type MEWPs. The RAMS must require: identification of all overhead hazards (power lines, steelwork, overhead cranes) before positioning the MEWP; minimum clearance from unprotected overhead lines (5 m for HV, no contact with any line); and where the MEWP may be operated near lines, a Safe System of Work agreed with the network operator. Goal posts, height restrictors, or spotter systems may be required.

Rescue procedure for entrapment or incapacitation

A trained MEWP rescue person must be available at ground level whenever a MEWP is in use. The rescue procedure must describe how the platform will be lowered to ground in the event that the operator becomes incapacitated (using ground controls or manual descent). WAH 2005 requires a rescue plan — 'call 999' is not sufficient as the attending crew may not have a rescue plan for the specific MEWP type on site.
