Elevating work platforms

OSHA has stated that it may refer to industry consensus standards such as ANSI A92.3, Manually Propelled Elevating Aerial Platforms and ANSI A92.6, Self-Propelled Elevating Work Platforms to enforce abatement of serious safety hazards involving scissor lifts. 

American National Standards Institute (ANSI) A92.2—Vehicle Mounted Elevating and Rotating Work Platforms and A92.6—Self-Propelled Elevating Work Platforms. 

Some powered platforms have controls at the platform or basket. Usually there is a second set of operator controls at ground level for general and emergency use. The platform should lock at the level desired and not be subject to free fall if there is a power failure. Users must leam how to set up and operate elevated work platforms. Lifelines connect fall protection harnesses or safety belts to the platform to prevent workers from falling. Controls should be fail-safe and have features to prevent inadvertent actuation. Some controls interlock to level indicator switches to prevent tipping the equipment over. 

The event spurred several investigations and discussion about football practice-related decision-making and who has responsibility for all personnel involved in a practice session. Some schools created or changed polices and procedures related to use of scaffolds and portable towers for video taping athletic practices. Many of the procedures covered anchoring of elevated work platforms, decisions for use in windy or adverse conditions, and safety procedures for their use.

Machinery originally designed as vehicle-mounted aerial devices (for lifting personnel) and self-propelled elevating work platforms. 

General requirements. The use of a crane or derrick to hoist employees on a personnel platform is prohibited, except when the erection, use, and dismantling of conventional means of reaching the worksite, such as a personnel hoist, ladder, stairway, aerial lift, elevating work platform or scaffold, would be more hazardous or is not possible because of structural design or worksite conditions. 

Q. What are OSHA s fall protection requirements for working from scissor lifts, aerial lifts and boom-type elevating work platforms You also ask us to explain the difference between fall restraint systems, positioning systems, and fall arrest systems. 

Restraint Systems —A restraint system prevents a worker from being exposed to any fall. If the employee is protected by a restraint system, either a body belt or a harness may be used. When a restraint system is used for fall protection from an aerial lift or a boom-type elevating work platform, the employer must ensure that the lanyard and anchor are arranged so that the employee is not potentially exposed to falling any distance.
