Manufacturing workplaces combine multiple serious hazard categories — moving machinery, hazardous energy, chemical exposure, noise, and ergonomic strain — in environments where workers spend eight or more hours a day. OSHA's General Industry standards (29 CFR Part 1910) govern most manufacturing workplaces, and inspectors are familiar with the specific failures that recur across the industry.
Top OSHA Hazards in Manufacturing
Machine Guarding
Machine guarding (29 CFR 1910.212) was the tenth most-cited OSHA standard in FY2024 and the top citation in general industry manufacturing. Machines with moving parts — rotating shafts, cutting tools, presses, conveyors — must have guards that prevent workers from making contact with points of operation, nip points, and rotating parts. Guards must be fixed in place, not easily removable, and designed so they do not create additional hazards.
Common violations include:
- Guards removed for maintenance and not replaced
- Inadequate guarding at points of operation
- No guarding on in-running nip points (conveyor drives, roll equipment)
- Homemade guards that don't meet strength requirements
Lockout/Tagout
Manufacturing has the highest LOTO citation rate of any general industry sector. Every piece of equipment that workers service or maintain requires a machine-specific energy control procedure, trained authorized employees, and an annually audited written program. A single LOTO failure can cost a worker a hand — or their life. See our full LOTO compliance guide.
Hazardous Chemicals (HazCom)
Manufacturing workplaces commonly use solvents, lubricants, cleaning agents, coatings, and process chemicals. HazCom (29 CFR 1910.1200) requires a written program, a complete SDS library, labeled containers, and trained employees. HazCom is consistently among the most-cited general industry standards.
Noise
Many manufacturing environments — metal fabrication, woodworking, stamping, packaging — generate noise at or above 85 dBA. At this level, OSHA's Hearing Conservation Standard requires noise monitoring, audiometric testing, free hearing protectors, and annual training. At 90 dBA (the permissible exposure limit), feasible engineering and administrative controls are required in addition to hearing protection.
Forklift Safety
Manufacturing facilities are among the most heavily cited for powered industrial truck violations. Operator training and evaluation must be documented for every operator, daily inspection logs must be maintained, and pedestrian separation must be enforced. Forklifts kill roughly 85 workers per year and injure nearly 35,000.
Ergonomics
While OSHA does not have a specific ergonomics standard, the General Duty Clause covers ergonomic hazards that are recognized and likely to cause serious harm — repetitive motion, forceful exertion, awkward postures, and contact stress. Musculoskeletal disorders are among the most common workplace injuries in manufacturing. Proactive ergonomic programs reduce workers' compensation costs and demonstrate good faith in any OSHA proceeding.
Respiratory Hazards in Manufacturing
Depending on the processes involved, manufacturing workers may be exposed to metal dusts, wood dust, silica, welding fumes, isocyanates, or chemical vapors. OSHA's silica standard imposes specific requirements on stone, masonry, and countertop manufacturing. Welding fume exposures are addressed under the air contaminants standard and require engineering controls before respiratory protection.
Electrical Safety
Manufacturing environments contain significant electrical hazards — high-voltage equipment, control panels, and energy distribution systems. OSHA's electrical standards (29 CFR 1910 Subpart S) and NFPA 70E (the electrical safety standard referenced by OSHA) both apply. Arc flash hazard analysis and appropriate PPE for electrical work are requirements that many manufacturers overlook until an incident occurs.
Required Written Programs for Manufacturers
- Hazard Communication Program
- Energy Control (Lockout/Tagout) Program
- Hearing Conservation Program (if noise exposures at or above 85 dBA)
- Respiratory Protection Program (if respirators are used)
- Emergency Action Plan
- PPE Hazard Assessment (written certification)
- Confined Space Entry Program (if permit-required spaces exist)
- Bloodborne Pathogen Exposure Control Plan (if first aid responders are designated)
