Handling Livestock in Heat

Hot weather stresses animals and the people working with them at the same time. Planning the day around the heat is safer than pushing through it.

Why is hot weather a handling risk?

Heat stress makes animals uncomfortable, and uncomfortable animals are harder to predict. They may crowd shade, resist moving, breathe hard or become irritable. Pushing stressed animals through a chute or onto a trailer raises the chance of both animal and human injury.

People are at risk too. Hard physical work, heavy protective clothing, dust and close contact with animals that give off heat can add up quickly. Fatigue and dizziness also affect judgment, and poor judgment around large animals is how injuries start.

Heat does not affect everyone equally. Age, health conditions, medication, fitness and how recently someone has been working in the heat all play a part, so ask your health care provider about your own situation.

How can I schedule work around the heat?

Where you can, move gathering, sorting, vaccinating, hauling and other stressful tasks to the cooler part of the day. Early morning work is common, and some jobs can wait for a cooler spell. Check the forecast from the National Weather Service before planning a big day.

Build in breaks and finish before animals and people are worn out. If a job cannot be postponed, shorten it, add helpers and reduce how long animals are held in tight spaces.

Remember that conditions can change during the day. A job that started in comfortable weather can turn difficult by midday, so decide in advance what you will do if the heat builds, and be willing to stop.

• Check the forecast before planning handling
• Do the most stressful jobs at the coolest time
• Add people to shorten the job
• Postpone nonessential work during extreme heat

What do animals need during hot work?

Water, shade and ventilation matter most. Make sure clean water is available and that animals can reach it easily, and avoid crowding them in holding pens where air does not move. Ask your veterinarian or extension office about heat management for the species you keep.

Be careful with trucks and trailers. Parked animals can heat up quickly, and loading densities and transport rules vary. Confirm with your state agriculture department and follow guidance from your veterinarian and extension.

How do I protect myself and my crew?

Drink water regularly, take breaks in shade or a cool area, and wear lightweight clothing that fits the job. Heat illness can progress fast, so people should watch each other rather than rely on one person noticing for themselves.

OSHA and CDC publish heat safety information for outdoor workers, including how new or returning workers should ease into hot conditions. Read their current guidance rather than relying on memory, and ask your doctor about medications that may affect heat tolerance.

• Use a buddy system and check on each other
• Give new workers time to adjust
• Keep drinking water at every work site
• Know who has medical conditions that need attention

What are the signs that someone needs help?

Confusion, fainting, very hot skin, vomiting, severe weakness or stopping sweating when working in heat can be signs of a serious problem. Do not wait to see whether it passes.

Call 911 for a person who is confused, has collapsed or seems seriously ill. Follow the instructions of the dispatcher, and consider taking a first aid course from the American Red Cross so you know what to do before help arrives.

If you supervise others, make it easy for people to speak up. Workers who fear being seen as weak may hide early symptoms, so say clearly that stopping to cool down is expected.

How do I keep animal handling safe on hot days?

Slow, quiet handling is even more important in heat. Avoid rushing, avoid overcrowding, and give animals time to cool between steps. Frustration leads to shortcuts, and shortcuts in a hot pen are risky.

Check equipment too. Metal rails, trailers and chutes get hot to touch, and gloves help. Look for tired, overheated helpers and rotate tasks so nobody stays on the most demanding job for too long.

Who should I ask for heat guidance?

Heat guidance is updated by official sources, so check them each season. OSHA and CDC publish heat safety material for outdoor workers, the National Weather Service issues heat advisories, and your extension office can explain heat management for your animals.

Your veterinarian is the right person for questions about a specific animal, and your doctor is the right person for questions about your own health. Write the numbers down and post them in the barn so everyone can find them in a hurry.

• Check weather advisories each morning in hot spells
• Post emergency and veterinarian numbers in the barn
• Review heat plans with your crew before summer starts
