Halon • Halon fire extinguisher is important device to have, especially for emergency situations. It contains a gas that interrupts the chemical reaction that takes place when fuels burn. Halon fire extinguisher is often used to protect valuable electrical equipment since they leave no residue. • Such on expensive computers, server rooms, etc. • Since Halon manufacturing was banned, a hunt has been on for something that works as well. According to the Halon Alternatives Research Corp. , more than 20 different kinds of alternatives exist as direct replacements. • Halon Replacement • Those categories are inert gases and halocarbon compounds.

WARNING!! • It is important to understand that most people don’t die from burning but more often from the smoke from a fire. • Smoke / Fire will take the oxygen out of the room and cause suffocation.

Fire Life Safety • • • How to prevent fires from occurring: Class A – Ordinary combustibles: Keep storage and working areas free of trash Eliminate excess/unnecessary storage of combustible material Place oily rags in covered containers Class B – Flammable liquids or gases: Don’t refuel gasoline-powered equipment in presence of an open flame such as a furnace or water heater Don’t refuel gasoline-powered equipment while it is hot Keep flammable liquids stored in tightly closed, selfclosing , spill-proof containers. Pour from storage drums only what you’ll need. Store flammable liquids away from spark-producing sources. Use flammable liquids only in well-ventilated areas.

Fire Life Safety • How to prevent fires from occurring: (cont) • Class C – Electrical equipment: • Look for old wiring, worn insulation and broken electrical fittings. Report any hazardous conditions to your supervisor. • Prevent motors from overheating by keeping them clean and in good working order. A spark from a roughrunning motor can ignite the oil and dust in the unit. • Utility lights should always have some type of wire guard over them. Heat from an uncovered light bulb can easily ignite ordinary combustibles. • Don’t misuse fuses, never install a fuse rated higher than specified for the circuit. • Investigate any appliance or electrical equipment that smells strange. Unusual odors can be the first sign of fire. • Don’t overload wall outlets. Two outlets should have no more than two plugs.

Why Inmates Start Fires? ? • • • Boredem Mental health issues Revenge Grievances Carelessness Diversions

Firefighting Decision Criteria • Know department emergency procedures and evacuation routes • Know locations of extinguishers in your area and how to use them • Always sound the alarm regardless of fire size • Avoid smoky conditions • Ensure area is evacuated • Don’t attempt to fight unless: • Alarm is sounded • Fire is small and contained • You have safe egress route (can be reached without exposure to fire) • Available extinguishers are rated for size and type of fire • If in doubt, evacuate! “DON’T ATTEMPT TO FIGHT UNLESS YOU ARE TRAINED”

Evacuation Plans • Evacuation Plans: • Staff and inmates must be aware of the plan. • It shall be the responsibility of the Warden/designee to provide a system of fire prevention and control to ensure the safety of employees, inmates, and visitors. • Institutions/facilities with major fire fighting equipment shall be responsible for training the employees assigned to operate the equipment. • During an emergency, the Warden or highest ranking officer on duty shall have absolute and total authority concerning decisions made affecting the institution/facility.
