Importance of Maintenance of MEWPs - WSHC & WSH Bulletin
7 Jul 2010
A number of workers have lost their lives in recent incidents involving the use of mobile elevated work platforms (MEWP). The workers were trapped between components of the boom lift or scissor lift and surrounding structures. Therefore, it is important to ensure the safe and proper operation of MEWP, including checking that the MEWP is functioning and properly maintained. The frequency and type of maintenance and inspections of MEWP will depend on its usage, environmental conditions and the nature of operations.

Before work commences, a visual and functional routine checks should be conducted on the MEWP, including checking for:
Besides the routine pre-use checks, the MEWP must be serviced at stipulated timeframes, such as statutory inspection at least once in 6 months, or in accordance with the manufacturer’s recommendations. A preventive maintenance programme has to be devised by the user or owner based on his risk assessment and previous inspection/maintenance results. All inspections must be recorded and retained for inspection when the need arises.
