Grain Dryer Safety

A grain dryer combines fire, fuel, electricity and moving equipment in one place. This guide describes the hazards in general terms and points you to your manual and official sources.

Why do dryers need extra care?

Dryers use heat and often burn gas or other fuel. They also have fans, motors, augers and electrical controls, and they run for long hours during harvest. All of this adds up to a significant fire and injury risk.

The manufacturer's manual is the most important document for your dryer. Keep it handy and follow it.

Read the manual before the first run each season, even if you have used the dryer for years, since settings and checklists change.

What are the fire hazards?

Dust, chaff and grain fines can collect in and around a dryer and catch fire. Sparks, overheated parts and fuel leaks can all be ignition sources.

Regular cleaning and inspection, according to the manual and fire safety guidance, reduce the risk. Ask NFPA and your fire department about fire prevention for dryers.

If you see fire or smell smoke, get people away and call 911. Keep the area around the dryer clear of trash, straw, dry brush and stored materials. A clean site gives a small fire less to burn. Keep a record of cleaning and inspection dates.

What about fuel and gas safety?

Fuel systems, whether propane or natural gas, need proper installation and inspection by qualified people. A fuel leak is dangerous because of fire and explosion risk.

If you smell gas, leave the area, avoid creating sparks and call 911 or your gas supplier's emergency number from a safe distance.

Ask your fuel supplier and a qualified technician about inspections before each season. Gas shutoff locations should be known to everyone who works near the dryer, and marked clearly.

What about the moving parts?

Fans, augers and conveyors on a dryer can cause entanglement injuries. Guards must be in place, and equipment must be locked out before anyone works on it.

See the auger safety and lockout guides on this site, and follow your manual for service procedures.

Make sure that anyone who clears chaff or checks equipment knows how to lock the machine out first. Never bypass a safety switch, sensor or shutoff on a dryer. These devices are there because failures have caused fires and injuries in the past.

How do you work safely around heat and noise?

Dryers can be hot and loud. Heat can cause burns, and noise over time can harm hearing.

Ask an occupational health provider or AgriSafe about hearing protection and heat illness. Do not choose protective equipment by guesswork.

Hot surfaces can burn bare skin. Drink water and take breaks in cool places during long shifts near heat.

What is a safe routine during harvest?

Check the dryer before you start each season, and again on a regular schedule. Monitor it rather than leaving it unattended for long stretches if the manual advises monitoring.

Make sure someone always knows where you are and how to reach emergency services. Keep a fire extinguisher suitable for the setting where the manual or fire department recommends one.

Post the farm address and emergency numbers near the dryer in case a fire starts. Make sure that a second person knows when the dryer is running overnight and how to reach you.

Where can you get help?

Equipment dealers, fuel suppliers, fire departments and extension programs can all help. OSHA and NFPA publish public safety information.

Rules for fuel installation and electrical work vary by state and locality, so confirm with the official local authority or a licensed professional.

Insurance carriers often have loss control staff who can review dryer setups. Ask your agent whether that service is available.
