Heat Safety for Livestock Workers

Hot weather stresses animals and the people who care for them. When livestock need attention, it is easy for a worker to put the animals first and ignore their own warning signs.

Why are livestock workers at risk in the heat?

Animal care does not pause for hot days. Feeding, moving, treating and cleaning continue, often in barns, pens and trailers where air hardly moves. Heat from the animals themselves adds to the load.

Workers also feel loyalty to their animals and may push through discomfort to protect them. Remember that an injured or collapsed worker cannot help anyone.

Water matters for workers just as it does for animals. Many people refill the stock tank before filling their own bottle, so keep a personal container where you can reach it.

• Animal care continues in hot weather
• Facilities and handling add heat

How do animal handling tasks add heat strain?

Moving cattle or hogs, working in a chute or loading a trailer is hard physical work. Doing it in the heat raises body temperature quickly, and stressed animals may behave less predictably when everyone is hot.

Plan handling for cooler hours when possible, and slow down rather than rush animals and people. Check with your extension livestock specialist or veterinarian about handling animals in hot weather.

Equipment such as fans and sprinklers should be checked before hot weather, and electrical safety matters around water. Have a qualified electrician look at any wiring you are unsure about.

• Plan handling for cooler hours
• Slow the pace when animals and people are hot
• Avoid rushing animals in tight spaces

How can facilities help?

Shade, ventilation, clean water and well-designed pens help the animals, and they help the workers too. Barns with good airflow, fans in working order and shaded loading areas make the job less taxing.

Do not rely on your own guess about whether a building is safe. Ask a ventilation or extension specialist to assess it, and maintain equipment so it works when needed.

Rest in a place away from animals, so you can actually relax, and not in a pen where you need to keep watching your footing.

• Shade at pens and loading areas
• Working fans and ventilation
• Water for people near animal work
• A quiet place to rest away from animals

What does a work plan look like?

Schedule the heaviest tasks in cooler parts of the day, rotate people and set up check-ins. Make sure someone knows where each worker is and when they should be done.

Agree on a stop signal. If a worker feels dizzy, nauseated, confused or weak, they stop and tell someone without needing to justify it.

Veterinarians and extension livestock staff can advise on animal handling in heat, but your own health questions belong with a medical professional, so ask both.

• Agree on a stop signal
• Rotate people through hard tasks

What should you watch for in coworkers?

Look for unusual tiredness, headache, heavy sweating, cramps, irritability or confusion. A person who makes odd choices near large animals is at risk of heat illness and of an injury.

Confusion, fainting or a seizure is an emergency. Call 911 immediately and follow the dispatcher's instructions.

• Unusual tiredness or heavy sweating
• Headache, dizziness or nausea
• Irritability or odd decisions near animals

What about working alone?

Many livestock chores are done alone, early or late in the day. A lone worker who collapses in a barn may not be found quickly.

Set up a check-in system with family or a neighbor, carry a phone and tell someone your plan. Know your farm's address so responders can find you.

• Share your plan with someone
• Carry a phone and know your address

Where can you get official guidance?

NIOSH and OSHA publish heat guidance for outdoor and agricultural work, and extension offices offer livestock-specific advice. Requirements for employers vary by state, so confirm what applies with OSHA and your state agency.

Your veterinarian and extension specialist can help with animal heat stress, but they cannot replace medical advice about your own health.

• Confirm employer rules with OSHA and your state agency
• Ask your veterinarian about animal heat stress
