Inspect the tackle-block assembly before each use.
Lubricate the tackle-block pulley wheels when necessary.
Keep tackle-block ropes under cover to guard the ropes against deterioration when
weather threatens.
Do not expose tackle-block ropes to acids. Ropes exposed to acids will deteriorate
and become unsafe.
Do not permit tackle-block ropes to scrape against sharp projections such as
scaffolds, windowsills, beams, or building walls.
Ensure that the ropes are not pinched between hard surfaces when ropes are subjected
to heavy loads.
Do not run ropes through sheaves that are too small because the sheave's size will
increase the wear on ropes.
Lubricate the ropes with beef tallow when required.
Do not allow ropes to slip over pulley wheels that do not turn.
Inspect hooks for cracks or bends before using them again when cornice hooks have
been subjected to strain.
Inspect each plank before its use when planking is used as a part of a scaffold.
Always inspect swing-stage stirrups before each use.
Do not walk under a scaffold.
Do not reeve a set of blocks on the ground where dirt, dust, or mud will get on the
ropes.
Do not use a scaffold without a guardrail.
(8) Inspection. Before each use, inspect all units that form a part of the scaffold and the units
used in conjunction with the scaffold. You should inspect-
Wooden platforms, guardrails, toeboards, metal stirrups, and hooks for worn parts.
Steel cables for wear signs, kinks, worn parts, broken wires, or corrosion.
Fiber ropes for any strands that are broken, cut, or weakened.
