One of the key conditions for MEWP stability is the ability of the ground or structure to safely support the weight of the MEWP at its point of contact with the ground in all configurations. Failure to consider the load-bearing capacity of the ground could potentially cause the MEWP to go out of level, become unstable, and overturn.
Scissor lifts are not designed to hold banners. Attaching banners to a scissor lift will increase the surface area and create a "sail board” effect which will destabilize or potentially turn over a MEWP.
The following guidance is intended to help employers differentiate between the possible options available when considering the selection of appropriate equipment where the increased risk of entrapment has been identified.
This document outlines a major inspection scheme to validate structural integrity and functionality of critical components of a mobile elevating work platform (MEWP). Such a scheme may be undertaken to determine if a machine is within safe design and use criteria beyond the manufacturer’s design life. Design life is defined as the duration determined by the manufacturer for which a structure or a structural component may be used for its intended purpose with recommended maintenance.
When working from a boom- type Mobile Elevating Work Platform (MEWP), it is strongly recommended that a lanyard short enough for the wearer to be restrained within the platform be used. The lanyard may contain an energy-absorbing device, provided it is short enough to restrain the wearer within the platform. This includes Static Booms (1b) and Mobile Booms (3b).
Mobile elevating work platforms (MEWPs) are specifically designed to lift people to a position where they can work at height safely within the platform. MEWPs are not designed to transfer people from one level to another, or for people to exit the platform at height.
MEWP overturn incidents often result in serious injuries or fatalities. Instability leading to overturn is commonly among the top four causes of lost time incidents (LTIs) annually, according to global data.
