Heat Safety in Poultry Houses

Working in a poultry house means warm air, humidity, dust and physical work, often with little chance to cool off. Heat safety needs its own plan.

Why are poultry houses a heat concern?

Birds give off heat and moisture, and enclosed buildings can hold both. Heavy ventilation is usually in place for the flock, but a worker's heat load can still be high, especially during catching, loading or cleanout.

A summer afternoon can make an already warm building dangerous. Plan for it, not around it.

A buddy system matters in a large house where noise and equipment hide what is happening. Two people entering together can spot trouble sooner than one who works alone.

• Warm, humid, dusty air
• Heat from the birds themselves

Which jobs are hardest in the heat?

Catching and loading birds, depopulation, cleanout and equipment repairs are some of the most physical jobs. Crews doing them may work in dust, in masks or respirators, and with limited breaks.

Respirators and protective clothing add heat strain. Follow manufacturer instructions and your safety program, and ask OSHA or your extension office about heat and respiratory protection together.

Dust and ammonia can irritate the lungs, and heat makes breathing feel harder. Ask an occupational health provider about respiratory protection that fits you, and follow your written safety program.

• Catching and loading
• Cleanout and cleaning
• Repairs in closed spaces
• Work in respirators or protective suits
• Follow respirator manufacturer instructions
• Heat and dust together raise strain

How can ventilation help the workers?

Ventilation systems protect birds and can lower worker heat, but they must be maintained and tested. A failed fan or power outage can turn a building dangerous quickly.

Have backup plans for outages, and ask an extension poultry specialist or equipment provider about alarms and maintenance. Never enter a space you suspect is unsafe without proper help.

If a power failure or fan failure occurs, workers need to know what to do and when to leave. Planning ahead with your integrator, equipment dealer and local fire department is wise.

• Test fans and alarms regularly
• Plan for power outages
• Backup plan if power fails
• Maintenance schedule before summer

How should work and rest be scheduled?

Schedule heavy tasks in cooler hours, rotate crews and keep rest areas outside the house with shade and water. Rest inside the same warm air does not give the body much recovery.

Check NIOSH and OSHA for current guidance on work-rest schedules rather than using remembered numbers.

Keep a log of temperatures and incidents during hot weather, which helps you see patterns and plan better for the next season.

• Rest outside the house in shade
• Rotate crews during heavy tasks
• Heavy tasks in cooler hours
• Water carried to the rest area

What symptoms should crews know?

Look for heavy sweating, headache, dizziness, nausea, cramps, confusion or unusual behavior. Dust and noise can mask problems, so check on each other often.

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

Talk with every worker about how they are feeling before each shift. A short check at the door can catch someone who is already ill or short on sleep.

• Watch coworkers closely
• Call 911 for confusion or collapse

How do contract and crew workers fit in?

Many catching and cleanout crews are contracted or temporary. Make sure they receive the same orientation on heat, water and the farm's address as permanent staff.

Employers should confirm requirements with OSHA, the U.S. Department of Labor and the state agency, since they vary.

Allow extra time for catching and cleanout crews to take breaks. A tight turnaround is a common reason that safety plans get dropped.

• Same orientation for contract crews
• Confirm obligations with OSHA and the Department of Labor

What preparation helps before an emergency?

Post emergency contacts and the address, keep gates open for responders and train people on first aid through the American Red Cross or another provider.

Meet with your local fire and EMS about access to your property and buildings.

• Post address and contacts
• Train on first aid with the Red Cross
• Meet your local fire and EMS
