12 Aug Heavy Equipment Operation – JSA

Heavy Equipment Operation Job Safety Analysis (JSA)

Job / Task

Operation of heavy equipment, including excavators, loaders, dozers, graders, skid steers, backhoes, and similar mobile equipment used for construction, excavation, material handling, grading, and site work.

Purpose

This Job Safety Analysis (JSA), also known as a Job Hazard Analysis (JHA), identifies hazards associated with heavy equipment operation and establishes controls to prevent struck-by, caught-between, rollover, equipment contact, utility, fall, and other injuries.

Personnel Qualifications

Heavy equipment shall be operated only by employees who are trained, competent, and authorized for the specific equipment and task. Operators shall understand the equipment’s controls, limitations, operating procedures, and worksite hazards.

Operators shall:

• Complete required training and evaluation before operating assigned equipment.
• Follow the manufacturer’s operating instructions and applicable site procedures.
• Perform required pre-use inspections.
• Use seat belts or other required operator restraints.
• Maintain control of the equipment at all times.
• Stop operation when an unsafe condition, equipment defect, or unclear communication exists.

Required PPE

PPE shall be selected based on the worksite hazards and may include:

• Hard hat or safety helmet.
• Safety glasses with side protection.
• High-visibility clothing where employees may be exposed to vehicle or equipment traffic.
• Safety footwear appropriate to the work.
• Hearing protection where required.
• Work gloves when performing ground-level tasks or equipment servicing.
• Additional PPE required by the task, material, or worksite.

PPE does not replace equipment guarding, safe distances, traffic controls, or other required engineering and administrative controls.
