approved and marked for operation in a hazardous location (one having potentially
flammable or explosive gases or particles) shall be prohibited. (14) Entanglement. Care
shall be taken to prevent rope, electric cords, and hoses, etc., from becoming entangled in
the aerial platform. (15) Capacity limitations. Rated capacities shall not be exceeded
when loads are transferred to the platform at any height. (16) Work area. The operator
shall ensure the area surrounding the aerial platform is clear of personnel and equipment
before lowering the platform. (17) Fueling. The engine (if applicable) shall be shut
down while fuel tanks are being filled. Fueling shall be done in a well-ventilated area
