Acquire &
install guard
Install a guard over the entire power transmission assembly.
The customer is responsible for acquiring or fabricating an appropriate guard
that meets all the requirements described in this section.
Note: A guard has not been supplied with the generator because the
manufacturer does not know the size and dimensions of the engine to
be used, nor in what configuration the customer will choose to mount
the generator & engine.
DANGER:
All parts of the power transmission assembly must be equipped with a
guard that prevents access to rotating parts. Clothing or hair can become
rapidly entangled in unguarded rotating parts, resulting in serious injury or
death.
Guard requirements. The guard must:
1) Prevent contact with all rotating shafts, pulleys, belts, and couplings.
2) Allow for adequate cooling ventilation and hot exhaust clearance, as
described in the previous section “4. Select a Suitable Site”.
3) Be constructed of non-combustible, heat-resistant, durable and impact-
resistant material.
Expanded metal, perforated or solid sheet metal, wire mesh on a frame of angle
iron, or iron pipe securely fastened to the frame can be used.
Openings in, around, and between guards can allow fingers/hands to protrude
into dangerous areas where hazards exist. The allowable size of openings
depends on the distance of the opening from specific hazards. Follow the OSHA
guidelines below (extracted from 20 CFR 1910.217 Table O-10) for maximum
opening size:
