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.

Mobile elevating work platforms (MEWPs) are considered to be one of safest ways of performing temporary work at height. This technical guidance explores the importance for all MEWPs to be kept in a safe working condition throughout their working life to ensure continued safe and efficient operation over time.

This guidance is intended to: provide information for those who plan and manage MEWP operations; provide information on the main hazards when using a MEWP in pedestrian control mode; provide information on the risk control measures to adopt when using pedestrian controls; provide general global guidance for those who undertake tasks to prevent incidents occurring.
