A. Except for an occupant of the platform performing the duties of a signal person, employees shall keep all parts of the body inside the platform during raising, lowering, and positioning.
B. When employees are to exit or enter a hoisted personnel platform that is not landed, the platform shall first be secured to the structure where access or egress is to take place, unless securing to the structure creates an unsafe situation.
C. When employees work from the platform, the platform may not be secured to any structure other than the crane, derrick, or hoist.
D. Tag lines shall be used unless their use creates an unsafe condition.
E. The crane operator shall remain at the controls at all times when the platform is occupied.
F. The hoisting of employees shall be promptly discontinued upon indication of any weather condition or other impending condition which could adversely affect the safe hoisting of personnel on a platform.
G. Except as noted in § H, of this regulation, employees being hoisted shall remain in continuous sight of, and in direct communication with, the operator or signal person.
H. When direct visual contact with the operator is not possible and the use of a signal person would create a greater hazard for that person, direct communication alone, such as a two-way radio system, may be used.
