Mast Climbing Work Platforms (MCWPs), or mast climbers, are a type of construction elevating equipment used to perform work at height. Mast climbers are equipped with a powered drive unit for propelling the work platform up and down a vertical mast structure. As with any type of equipment used to accomplish work at height, safety hazards may be present. Such hazards can result in injury or death.

Training is necessary for anyone using mast climber equipment. NIOSH has developed an online tool to help those who might use mast climbers identify common hazards. This educational resource can also help employers, trainers, and safety and health professionals to prevent work-related falls. Using the inspection tool is not a substitute for OSHA training requirements for MCWPs.

Note: Every mast climbing work platform configuration and set-up is specific to the site. Always consult manufacturer specifications and guidelines for each specific set-up as they can vary from site to site. Mention of any company or product does not constitute endorsement by the National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention.
