Rope, Chain, Rigging, and Hoists
(1)Scope. These are standards for the safe use of hoists, rope, chain, and fittings.
(a)Mousing — Using small cordage or wire to prevent unintended separation of rigging components.
(b)Rope — Wire rope unless otherwise specified.
(3)Loading and capacity. Do not load any rigging equipment or hoisting device more than its rated safe working load or capacity.
(4)Inspection. Inspect rigging and hoisting devices before use and as necessary during use to ensure safety. Immediately remove from service defective rigging or hoisting devices.
(5)Operators — handling loads.
(a)Workers must not ride hooks, slings, rigging, or loads. Suspend or elevate a person only when using a safe personnel lift.
(b)Personnel lift must meet these requirements:
(A)The structure must be rigid and strong enough to support loads with a safety factor of 4 times the intended load.
(B)The personnel lift must be big enough to accommodate all persons without crowding, and to provide sufficient work space so workers will not hinder or obstruct each other.
(C)There must be standard guardrails on all sides of the personnel lift. (See 4/D, OAR 437-004-0320 (Guarding Floor and Wall Openings and Holes)(6) for guardrail design specifications.)
(D)The personnel lift must have supports on all four corners that provide full stability against tipping while occupied.
(E)Secure the load lifting attachment for the personnel lift to the crane or derrick hook in a way that will prevent accidental release.
(c)Only one person will give operating signals during hoisting operations.
(d)All persons must be in the clear before a signal is given to move a load or equipment.
