Agricultural work is physically demanding, often performed in extreme weather, and involves heavy machinery and hazardous chemicals. The fatality rate in agriculture consistently ranks among the highest of any industry in the U.S. OSHA's agricultural standards (29 CFR Part 1928) are different from the general industry and construction standards that cover most other employers — understanding which rules apply to farm operations is the starting point for compliance.
Tractor Safety and Rollover Protection (ROPS)
Tractor overturns are the leading cause of death in agriculture. OSHA's rollover protective structure (ROPS) standard (29 CFR 1928.51) requires that agricultural tractors manufactured after October 25, 1976 be equipped with ROPS and a seat belt.
- ROPS must meet ASAE/SAE strength standards and be properly labeled
- Seatbelts must be provided and worn whenever the tractor is operated with ROPS
- Folding ROPS must be kept upright except when height clearance prevents it — and must be returned to upright position immediately after
- ROPS must not be removed or disabled
- ROPS retrofits are available for older tractors — OSHA provides guidance on acceptable retrofit systems
Pesticide Safety and the Worker Protection Standard
Agricultural pesticide safety for farm workers is primarily governed by the EPA's Worker Protection Standard (WPS), which is enforced by EPA and state agencies rather than OSHA. However, OSHA's general duty clause and HazCom standard also apply to pesticide use. WPS requirements include:
- Central posting of safety information including emergency contact information and WPS safety poster
- Entry restriction intervals (REI) — workers cannot enter treated fields during the restricted-entry interval posted on the pesticide label
- Decontamination supplies — eyewash water, soap, and towels at field sites and near pesticide storage areas
- Training for all workers on pesticide safety before working in treated areas
- Personal protective equipment required by the pesticide label
- Access to pesticide safety information (Safety Data Sheets and labels) for all workers
Heat Illness Prevention
Agricultural workers — particularly those working outdoors in hot weather — face serious heat illness risk. Heat illness can escalate from heat cramps and heat exhaustion to life-threatening heat stroke rapidly. OSHA's General Duty Clause requires employers to protect workers from recognized heat hazards.
OSHA's prevention framework: Water. Rest. Shade.
- Water: Cool drinking water must be available nearby — one quart per worker per hour in hot conditions
- Rest: Provide rest breaks in cool or shaded areas, especially during the hottest parts of the day
- Shade: Shade structures or cool areas must be accessible when temperatures exceed 80°F
- Acclimatization: New workers and workers returning from absence need a gradual introduction to hot work — most heat-related deaths occur in the first few days on the job or the first hot days of the season
- Emergency procedures: Workers must know how to recognize heat stroke symptoms and what to do — call 911 immediately and cool the worker down while waiting for help

Field Sanitation
OSHA's field sanitation standard (29 CFR 1928.110) applies to farms that employ 11 or more workers on any given day. It requires:
- Toilet facilities — one toilet for every 20 workers, within a quarter mile or five-minute walk of the work location
- Hand washing facilities — one unit per 20 workers, with clean water, soap, and individual towels
- Potable drinking water — one quart per worker per hour, with individual cups or a fountain
- Workers must be told at the time of hire about the locations of facilities and their right to use them
Agricultural Machinery Safety
Beyond tractors, agricultural operations use combines, balers, augers, PTO-driven equipment, and irrigation systems — all of which present serious caught-in/between and struck-by hazards.
- All power take-off (PTO) shafts and connections must be guarded — PTO entanglements cause amputations and death
- Machine guards must be in place before operation and never removed while machinery is running
- Workers must be trained on pre-operation inspection and shutdown procedures for all equipment they operate
- Lockout/tagout procedures apply when workers service or clear jams in agricultural machinery
- Grain storage and handling — grain bins and augers require specific safety procedures and rescue equipment
Hazard Communication in Agriculture
OSHA's HazCom standard applies to agricultural operations that use hazardous chemicals beyond those covered by WPS. Fuels, lubricants, cleaning agents, and fertilizers may all require SDS on file and employee training.
Required Programs for Agricultural Employers
- Hazard Communication Program (if non-pesticide hazardous chemicals used)
- Emergency Action Plan
- Heat illness prevention program (documented plan strongly recommended)
- PPE Hazard Assessment — written certification
