Yuma agriculture heat plan: a guide for Arizona farm employers

Checked against Arizona’s published heat guidance on Oct 29, 2026 · By Anchor Point Apps · Not legal advice

Agriculture is the one sector where Arizona already has rules with teeth on drinking water, plus the new heat guidance on top. Don’t treat them as the same thing.

Two layers

According to the Arizona Farm Bureau’s 2026 guide, agricultural employers face (1) a binding field sanitation standard in the Arizona Administrative Code, reported as covering operations with five or more employees doing hand labor, with free potable water, at least 2 gallons per employee per day, no warmer than 80°F, in individual cups, and (2) the heat emphasis program and 2026 guidance. The guide says the guidance’s recommendations (about one quart per employee per hour; closer to 60°F water) “are not currently law,” and advises meeting the sanitation standard as the legal floor and adopting the guidance where feasible. Check the current code text yourself.

What the heat guidance adds

• Responsibilities. Who owns the plan, who supervises each crew, and who can stop work.
• Water. Free, potable, cool drinking water close to the work. For water that isn’t plumbed, the task force recommends enough at the start of the shift for at least one quart per employee per hour, or an effective procedure to replenish it. “Cool” is described as ideally 59°F, with clean, regularly maintained containers.
• Shade. Natural or constructed shade that doesn’t trap heat, big enough for employees on break to sit in a natural posture, open on at least three sides (or mechanically ventilated), close to the work and free of hazards. Functioning air-conditioned buildings or vehicles can count.
• Rest. Workers can take a preventive cool-down rest in the shade, without penalty, when they feel the need; intervals should reflect temperature, humidity, workload, PPE and acclimatization.
• Acclimatization. A written plan: either follow the CDC/NIOSH acclimatization plan, or design your own that covers acclimatized vs. unacclimatized workers, the heat load of clothing and PPE, higher-risk workers, and re-acclimatizing returning workers.
• Training. For supervisors and employees before heat exposure, in a language they understand, covering employer responsibilities and employee rights, your written procedures, risk factors, monitoring tools, types and signs of heat illness with first aid and emergency response, drinking small amounts of water often, acclimatization, and reporting symptoms right away. Retrain at least annually before exposure, and after a serious heat-related illness. Keep training records.

Farm-specific points

• Walking distance to water and shade. The Cronkite News report quotes a southern Arizona organizer describing workers who walk long distances to water or shelter in hazardous spots like behind tractor tires. The guidance says water and shade should be as close as practicable and reasonable, and shade must be free of hazards.
• Harvest contractors and crews. Farm labor contractors may be separate employers. The Arizona Farm Bureau recommends requiring contractors to hold their own compliant plan and checking on site.
• Language. Training must be in a language workers understand, which for many farm crews is Spanish, and for some crews may be an Indigenous language. Plan for how you’ll train them. ADOSH’s consultation group has published a Spanish heat flyer.
• Acclimatization. Seasonal and migrant workers arriving from cooler climates are the unacclimatized workers the guidance is about. Log your approach.

Worth knowing: ADOSH publishes a free, customizable example Heat Illness Prevention Plan and offers free, non-enforcement consultations (the Arizona Farm Bureau lists the consultation line as (602) 542-1769; confirm on the ADOSH heat page). If you’re comfortable editing a generic template, start there. A paid builder only makes sense if you’d rather answer a short set of questions and get a plan, training sign-in sheet and logs tailored to your trade and crew, in English and Spanish.
