Smoke Inhalation Safety

Smoke from a barn, shop or brush fire can injure lungs quickly, sometimes before flames are visible. Prevention and calling for help early matter most.

Why is smoke so dangerous?

Fire smoke contains gases and particles that can harm the airways and limit the body's ability to use oxygen. The danger can come from hay, bedding, plastics, wiring, chemicals and fuels, each of which burns differently and can release different substances.

Smoke can also cloud vision and cause confusion, which makes escape harder. This is why fire safety agencies stress getting out and calling for help rather than trying to fight a growing fire.

Fire safety agencies also point out that smoke can spread much faster through a building than people expect, which is one reason to act at the first sign. Keep in mind that a person overcome by smoke may not recognize how impaired they are, so watch coworkers and family members closely. If anyone in the household has asthma or heart disease, discuss with their provider ahead of time what to do after smoke exposure.

Where do farm smoke hazards come from?

Farms mix fuel, stored feed, equipment, electrical systems and bedding under the same roof. Heated hay, overloaded circuits, welding sparks and equipment faults are common starting points that safety groups discuss.

Smoldering fires can produce smoke with little visible flame, so an unexplained smell or haze in a barn or shed deserves attention.

• Hay and bedding storage
• Shop welding, cutting and grinding
• Old or overloaded wiring
• Heaters and fuel storage
• Brush and trash burning

What does prevention look like?

Prevention starts with fire safety basics from the NFPA and your local fire department: working smoke or heat detection where appropriate, clear exits, tidy storage, safe handling of fuel, and routine electrical inspection by a qualified electrician.

Ask your fire department to visit and look at your buildings. Many departments are glad to help farms plan access, water sources and how to reach each structure.

Check that extension cords and heaters are used as their manuals direct, and replace damaged cords instead of repairing them with tape.

What should you do if there is a fire?

Call 911 and get people and animals out only if it is safe to do so. Do not go back into a smoke-filled building. The decisions in a fire are better made with training, so ask your fire department or the Red Cross about fire safety and emergency planning for farms.

This article does not give step-by-step emergency instructions. Follow the guidance of emergency dispatchers and recognized training programs.

Keep roads and lanes clear so fire trucks can reach every building, and mark water sources so responders can find them.

What about smoke from burning and brush piles?

Smoke from burn piles can drift to neighbors, roads and your own family. Local rules on burning vary by town, county and state, so check with your local fire department or forestry agency before burning anything.

Keep burning supervised and never burn treated materials, plastics or chemical containers, which can release harmful substances. Pay attention to wind and to official burn restrictions.

When should someone get medical care?

Anyone who has been in smoke and has a cough, hoarse voice, trouble breathing, chest pain, headache, dizziness, or confusion should be checked by medical professionals. Some effects can show up hours later, so do not assume that feeling fine means no injury.

Call 911 for severe symptoms. Tell responders what burned and how long the person was exposed. Follow up with your regular provider and mention your farm exposures.

A medical provider can explain what follow-up care or monitoring is needed after significant smoke exposure, particularly for people with asthma or heart conditions.

How can families and crews prepare together?

Safety is easier when everyone knows the plan before something happens. Hold a short family or crew meeting each year to review where exits are, where people meet outside, and who calls 911. Practice makes people calmer and faster when it counts.

Teach children and new workers that the right response to smoke is to leave and tell an adult, not to investigate. The Red Cross and NFPA offer education materials that families can use, and local fire departments often provide visits.

Keep a list of important numbers, directions to your farm for dispatchers, and a note of any hazardous materials stored in each building. Giving responders accurate information helps keep them safe too.

• Agreed meeting place away from buildings
• Clear directions to your farm for dispatch
• Note of fuels and chemicals in each building
• Annual drill and review
