|Note: ||Guardrails may be used to safeguard: |
| ||• Flywheels. |
| ||• Cranks and connecting rods. |
| ||• Tail rods and extension piston rods. |
| ||• Horizontal belts in a power generating room. |
| ||• Clutches, cutoff couplings, or clutch pulleys in an engine room occupied only by an attendant. |

• Make sure top rails are:
– Strong enough to withstand a force of at least two hundred pounds.
– Between thirty-nine and forty-five inches above the floor, platform, runway, or ramp.
• Make sure guardrails have an intermediate rail (midrail) installed approximately halfway between the top rail and the floor, platform, runway, or ramp.
• Make sure rails do not extend beyond the end posts of the guardrail and create a projection hazard.
• Make sure toe boards, if required by this chapter to safeguard a machinery hazard, are:
– At least four inches high.
– Securely fastened in place with no more than one-fourth inch between the bottom of the toe board and the floor, platform, runway, or ramp.
– Made of substantial material that is either solid or that has openings in the material no larger than one inch.
