Engineers and winchmen shall accept signals only from the designated signalmen. Good practice: if you are not the designated signalman, do not give signals to the engineer or winchman.
Piling going into the leads
All employees shall be kept clear when piling is being hoisted into the leads. Good practice: know where the clear zone is before the lift starts, and stay out of it.
Cutting off pile tops. Pile driving operations shall be suspended, except where the cutting is located at least twice the length of the longest pile from the driver.
Steel tube piles being blown out. Employees shall be kept well beyond the range of falling materials.
Driving in an excavated pit. The pit walls shall be sloped to the angle of repose, or sheet-piled and braced.
Jacked piles. All access pits shall have ladders and bulkheaded curbs to prevent material from falling into the pit.
The rule lists protections the pile driving equipment must have. Good practice: look for each one before you work on or near the rig.
Overhead protection
Overhead protection that does not obscure the operator's vision and meets subpart N shall be provided. It shall be the equivalent of 2-inch planking or other solid material of equivalent strength.
Stop blocks
Stop blocks shall be provided for the leads to prevent the hammer from being raised against the head block.
Blocking device
A blocking device capable of safely supporting the weight of the hammer shall be provided for placement in the leads under the hammer at all times while employees are working under the hammer.
Head block guards
Guards shall be provided across the top of the head block to prevent the cable from jumping out of the sheaves.
Inclined leads
When the leads must be inclined in the driving of batter piles, provisions shall be made to stabilize the leads.
Guys, outriggers and more
Guys, outriggers, thrustouts, or counterbalances shall be provided as necessary to maintain stability of pile driver rigs.
Fixed leads shall have a ladder and adequate rings or similar attachment points so the loft worker can engage his safety belt lanyard to the leads. If the leads have loft platforms, they shall be protected by standard guardrails.
Hoses and steam lines
Steam hose to a steam hammer or jet pipe shall be securely attached to the hammer with chain or cable (at least 1/4-inch diameter) to prevent whipping if the joint at the hammer breaks. Air hammer hoses get the same protection.
Safety chains, or equivalent means, shall be provided for each hose connection to prevent the line from thrashing around if the coupling comes loose.
Steam line controls shall be two shutoff valves, one of them a quick-acting lever type within easy reach of the hammer operator.
Clearing brush and trees puts you in contact with plants. Employees engaged in site clearing shall be protected from the hazards of irritant and toxic plants and suitably instructed in the first aid treatment available.
Good practice: if you do not know what first aid applies to the plants on your site, ask before you start work.

Site clearing
Guards on clearing machines
All equipment used in site clearing shall have rollover guards.
Rider-operated equipment shall also have an overhead and rear canopy guard.
The overhead covering shall be not less than 1/8-inch steel plate or 1/4-inch woven wire mesh with openings no greater than 1 inch, or equivalent.
The opening in the rear of the canopy shall be covered with not less than 1/4-inch woven wire mesh with openings no greater than 1 inch.

Fact-checked against the regulation text on October 09, 2026. This certificate records completion of awareness training based on OSHA 29 CFR 1926.603(a)(3) through (a)(12) and 1926.603(c), and 29 CFR 1926.604(a). It is not an OSHA card or license, and it does not by itself meet the instruction requirement of 29 CFR 1926.604(a)(1). Your employer must still protect employees engaged in site clearing from hazards of irritant and toxic plants and suitably instruct them in the first aid treatment available. 29 CFR 1926.603 has no training paragraph; your employer must still provide the pile driving equipment protections and follow the work practices it requires.
This guide explains the rule in plain words. Always read the regulation itself and your employer's site-specific procedures.
