HSE safety alert: Mast climbing work platforms (MCWPs): Failure to detect mechanical failure in drive units

4th May 2022

HSE has issued a safety alert advising of a serious technical fault found with mast climbing work platforms (MCWPs).

The alert requires those involved in MCWP activities to check that MCWPs comply with Regulation 4 of the Provision and Use of Work Equipment Regulations 1998, specifically, to ensure that undetected mechanical failure in drive units cannot lead to the uncontrolled fall of the platform.

It includes advice on detection and prevention of potential failure where MCWPs rely on two drive units per mast as the means to ensure safety.

MCWPs are used widely across construction projects and in other industries. Employers, users and suppliers/installers should take the actions required in this alert. Source: HSE Safety Alert
