SUBJECT:     Safe Access, Fall Prevention and Fall Protection involving Self-Propelled Mobile

This Program Information Bulletin (PIB) applies to Safety and Health Administration (MSHA) enforcement personnel, underground and surface mine operators, and independent contractors.

This PIB provides information on providing safe means of access, fall prevention, and fall protection to miners operating, conducting maintenance or service activities, or accessing work platforms of self-propelled mobile equipment.

Accessing, operating or maintaining self-propelled mobile equipment often requires activities such as climbing ladders, or walking on machinery surfaces which expose miners to hazard such as falls during all types of weather conditions. Modern mobile equipment is designed to minimize slip and fall hazards; but, large machinery, new and old, can require access at heights with a fall potential that can cause serious injury. The following precautions can reduce slip and fall accidents from mobile equipment.

In addition, equipment manufacturers may be providing safe access, fall prevention and fall protection by complying with ISO 2867, "Earthmoving Machinery - Access Systems" or SAE J185, "Recommended Practice for Access Systems for Off-Road Machines." Any modifications to mobile equipment should generally not be made without an engineering evaluation and concurrence by the manufacturer of the equipment. Unsafe access and fall hazards from mobile equipment can be reduced by the use of: Operators are responsible for providing documentation to verify that their equipment is ISO 2867 certified. Inspectors may use the certification documents in considering if safe access, fall prevention and fall protection is being provided.
