(d) Safety latches on hooks for
				damage;
(e) Hooks for deformation,
				cracks, excessive wear, or damage such as from chemicals or heat;
(f) A legible and applicable operator's
				manual and load chart is in the operator's cab or station;
(g) A portable fire extinguisher, with a
				basic minimum extinguishing rating of 10 BC must be installed in the cab or at
				the machinery housing;
(h) Crane
				cleanliness and housekeeping. Inspect for trash, oil, grease, debris or
				excessive dirt on crane components and catwalks, if applicable;
(i) Wire rope reeving for compliance with the
				manufacturer's specifications;

(u) Safety devices and
				operational aids for proper operation (including significant
				inaccuracies);
(v) Gasoline,
				diesel, electric, or other power plants for safety-related problems (such as

				operation;
(w) Chains and chain
				drive sprockets for excessive wear of sprockets and excessive chain
				stretch;
(x) Travel steering,
				brakes, and locking devices, for proper operation;
(y) Tires for damage or excessive
