Ergonomics and MSD Prevention
Musculoskeletal disorder prevention — lifting, repetitive motion, awkward postures.
What this document is
This document is a plain-English compliance guide and written program for ergonomics and musculoskeletal disorder prevention. It explains the requirements, provides assessment tools, and gives practical steps to reduce injury risk on construction sites.
The regulation that requires it
Cal/OSHA §3457 in Title 8 of the California Code of Regulations addresses Repetitive Motion Injuries. The section requires employers to establish a program that minimizes repetitive motion injuries when they are a known workplace hazard. The federal OSHA General Duty Clause (Section 5(a)(1) of the OSH Act) also applies when ergonomic hazards create a recognized serious risk of musculoskeletal disorders. These rules require employers to identify hazards, evaluate jobs, and implement feasible controls.
Who needs it
California contractors and employers in construction trades face the highest risk because of frequent heavy lifting, repetitive tasks, and awkward postures. General contractors, subcontractors, and any employer with employees performing manual material handling or repetitive work in California must comply with Cal/OSHA §3457. Employers in other states follow the OSHA General Duty Clause when ergonomic hazards are present.
What happens without it
OSHA and Cal/OSHA can issue Serious citations for ergonomic hazards with penalties currently ranging from $16,131 up to $161,323 for Willful or Repeat violations per the published penalty schedule. Inspections often occur after employee complaints or reported MSD injuries. Multi-employer worksites can result in citations to both the controlling contractor and the exposing employer.
