Fire Extinguisher Types for Farms

Not every extinguisher is right for every fire. Farms have wood, fuel, electrical equipment and sometimes chemicals, so the choice should be made with a qualified source.

Why does the type of extinguisher matter?

Fires are classified by what is burning, and extinguishers are labeled for the kinds of fire they can fight. Using the wrong type can fail to put the fire out or make things worse, for example when water is used on a fuel or electrical fire.

The label on the extinguisher tells you what it is made for. Read it before you need it.

Extinguishers are not interchangeable, and one multi-purpose unit may not cover every hazard in every building. Ask a qualified source what fits. Keep this knowledge fresh by reading labels again each season.

• Match the extinguisher to the fire
• Read the label now, not in an emergency
• Wrong choices can make a fire worse

What hazards do farms usually have?

Farms commonly have ordinary combustibles like hay, wood and bedding, flammable liquids such as fuel and oil, electrical equipment and in some places cooking equipment or chemicals. Each hazard may call for a different approach.

A good first step is to list the hazards in each building and vehicle. Then ask your fire department or a qualified provider which extinguishers fit each place.

Shops, barns, house kitchens, vehicles and machinery may each need something different.

• List hazards by location
• Ask about buildings and vehicles separately
• Update the list when things change

How do I choose size and rating?

Ratings and sizes affect how much fire an extinguisher can handle and how heavy it is to carry. NFPA standards and local fire codes cover what is needed and where. Do not choose from memory or from a store display alone.

Get advice from your fire department, your insurance provider or a qualified fire equipment provider who does not simply sell the largest unit.

Heavier units can hold more agent but can be hard to use in a hurry. Choose one the people who need it can handle.

• Follow NFPA guidance
• Ask about local code
• Choose something you can lift and use

Where should extinguishers be placed?

Place them where you can reach them quickly and safely, near exits and near hazards but not so close that a fire blocks access. Mount them at a height and in a way that fits the manufacturer's instructions, and make sure they are visible.

Machines and vehicles may need their own. Make sure the mount holds in rough conditions.

Placement should not require walking toward the fire to reach the unit. Make sure the unit is not blocked by tools, feed, boxes or parked vehicles.

• Near exits
• Visible and accessible
• Mounted securely on machines

Who should be trained to use them?

Everyone who might need one should know where they are and have had hands-on practice. Many fire departments and safety groups offer classes. Training explains the basic principles, including when not to fight a fire.

Remember that an extinguisher is for small fires, and your first move is to call 911 and ensure everyone is safe.

Check the gauge or indicator and the tamper seal as the manufacturer describes, and keep any records your insurer or fire department asks for. Short drills at the start of the season help people remember steps under pressure, which is when a plan is needed most.

• Hands-on practice
• Know when not to fight
• Call 911 first for any growing fire

What are the limits of extinguishers?

An extinguisher has a limited amount of agent and a short working time. It will not control a large fire, and it is not meant to be used in smoke or when exits are threatened.

If a fire is bigger than you can handle, leave and call 911.

After any use, even partial, have the extinguisher serviced or replaced as the manufacturer directs.

• Limited time and capacity
• Not for large fires
• Exit first when unsure

What about special cases like grain, chemicals and livestock buildings?

Grain dust, chemical storage, fertilizer and animal housing present special problems. Ask your fire department and the product's safety data sheet about what is appropriate. In some situations, the right choice is not to fight the fire at all.

Give this information to your fire department before an emergency.

A pre-incident visit from your department can identify where extinguishers are not enough.
