The leading cause of agriculture fires is open flame caused by candles, matches, bonfires, sparks, static electricity, friction, welding and equipment. Other causes of fires may include natural resources such as spontaneous combustion and lightning. Most sugarhouses make use of either wood or oil/gas to fire the arch, so far in the operation is a constant danger.
How Fires burn
The elements necessary to create a fire are fuel, heat and oxygen. These elements constitute the fire triangle. Removal or control of one element will remove or control a fire hazard.
Know your fire extinguishers
Fire extinguishing equipment can be classified into two types: portable and fixed. However, a portable, ABC-rated fire extinguisher is more practical for agricultural use, capable of extinguishing Class A, B or C fires.
- Class A Fire - Combustibles such as wood and paper textiles, where a quenching, cooling effect is required.
- Class B - Flammable liquids, gasoline, oils, fats or paint, where oxygen exclusion or flame interruption is essential.
- Class C - Live electrical wiring, motors or appliances, where non-conductivity of the extinguishing agent is crucial.
- Class D - Combustible materials, magnesium, sodium and potassium.
Control of fire hazards
- Cut down and remove weeds and brush from around sugarhouses. In buildings, check for excessive accumulation of dust, sawdust, cobwebs and other potential combustibles. Reduce and keep away from heat unneeded items that will burn. Arrange work areas so that flammables are safely away from ignition sources.
- Use approved electrical installations including proper fuses or circuit breakers, waterproof outlets, enclosed electric motors and similar equipment in any buildings which are cleaned periodically with high-pressure equipment.
- Inspect all wiring and electric motors and appliances for exposed wires, broken insulation, improper grounding and incorrect installations.
- Check the heating system. See that airshafts are clean of dust and debris, motors are cleaned and oiled (if necessary) each season, and pulley belts are in good working order. Check gas and fuel oil system for leaks and unsafe installations.
Minimize hazards on site
Strictly enforce a no smoking rule inside a building or areas where flammable and combustible materials are stored or near storage, shipping or receiving areas where boxes or other containers can easily start a fire.
Keep flammable liquids away from open flames and motors that might spark. Never smoke when refueling.
When transferring flammable liquids from metal containers, bind the containers to each other and ground the one being dispersed from to prevent sparks from static electricity. Clean up spills right away and put oily rags in a tightly covered metal container. Change your clothes immediately if you get oil or solvents on them.
Flammable liquids should be clearly marked and stored in approved containers in well ventilated areas away from heat and sparks. Keep above ground fuel storage tanks at least 40 feet from buildings.
Store compressed gases in a secure upright position, away from heat sources in an outdoor location. Keep different gases separately and full cylinders apart from empty cylinders, When heating with propane, keep 100-pound cylinders at least 15 feet away from heaters; keep large tanks at last 25 feet away.
Re-fuel machinery with care. Watch for and repair leaks in fuel lines, carburetors, pumps and filters. Keep engines properly tuned and timed to avoid back firing and exhaust systems in good condition to avoid sparks. Keep machinery properly lubricated to minimize friction.
Always have a fire extinguisher on hand during hot work. Watch for molten metal as it can ignite flammables or fall into cracks and start a fire that might not erupt until hours after the work is completed. Use portable cutting and welding equipment in clean work areas.
Keep flammables at least 35 feet from a hot work area. Be sure other tanks and other containers that have held flammable liquids are completely naturalized and purged before you do any hot work on them
Many materials under certain conditions heat spontaneously. Store vegetable and animal oils and paints or linseed - soaked rags in sealed containers in cool, well ventilated places away from other combustibles.
- Avoid clutter of flammable materials.
- Maintain heating systems.
- Install smoke detectors and fire extinguishers in buildings.
- Watch for leaks or deterioration in fuel storage and delivery equipment.
- Store fuel in food or drink containers.
- Smoke in areas where flammable materials are stored.
- Re-fuel engines inside buildings or when hot or running.
