Mobile Elevating Work Platform (MEWP) Safety for Supervisors
Mobile Elevating Work Platforms (MEWPs) can provide temporary elevated workspaces as an alternative to ladders or scaffolding. Due to the potential hazards of working at height, the American National Standards Institute (ANSI) and Canadian Standards Association (CSA) have developed standards related to MEWP design, construction, and use. This course covers the 2018 ANSI A92 and CSA B354 standards for supervisors of MEWP operators. It covers the latest MEWP Group and Type designations, and updated design, use, and training requirements.

Key Questions
One requirement for MEWPs with boom-mounted platforms is that the platform controls must be protected to prevent “sustained involuntary operation.” What does this mean?
This protection has been added so that if an operator were to become trapped, they would still be able to use the platform controls to stop or reverse platform movement.
What is the difference between Group A and Group B MEWPs?
They both have platforms that move up and down, but only Group B MEWPs are designed to extend beyond the tipping line.
What is the difference between the three Types of MEWPs?
An MEWP’s Type defines how it can be driven – with the platform stowed or elevated, and using the upper or lower controls.
What is the Site Risk Assessment requirement?
MEWP users (owners and renters) must complete a site risk assessment before work begins, communicate it to everyone involved, and include it in the Safe Use Plan.
What situations must the rescue plan (a part of the Site Risk Assessment) address?
The rescue plan must address the steps to be taken after a fall, if the platform becomes entangled, or if the machine fails.
Sample Video Transcript
Objects falling from an elevated platform pose a serious risk to persons on the ground. To minimize this risk: minimize the number of tools and other materials carried on the platform, secure materials on the platform and use tethered tools when possible, use a mesh barrier on the platform sides or floor (note: all platform additions and attachments must be approved by the manufacturer), and maintain a drop zone under the platform and require head protection in the work area.
