Question

when is it acceptable to use a personnel platform to raise and lower workers? other means of access would take too long other means of access would be more dangerous or impossible the platform would allow employees and materials to travel together the platform has already been attached to the crane at the start of the day

Explanation:

Personnel platforms are safety - critical equipment. Using them should be based on safety considerations. If other access methods are more dangerous or impossible (e.g., in high - rise construction where ladders or scaffolding cannot be safely set up), using a personnel platform is a valid option. Time - saving alone (just because other means take too long) is not a sufficient safety - based reason. Allowing employees and materials to travel together on a personnel platform is a violation of safety regulations (personnel platforms are for workers only in most cases). Just because the platform was attached to the crane at the start of the day is not a valid safety - based reason for using it to raise and lower workers.

Answer:

Other means of access would be more dangerous or impossible.
