The recordkeeping requirement may be satisfied by an operator’s written statement that the inspections have been made in accordance with the incorporated code. MSHA will accept such a certifying statement annually, without regard to format, if it is made available at the time of inspection.

This standard requires the use of safety chains or other suitable locking devices at certain high-pressure hose-to-hose or hose-to-machine connections.
