FIRES IN HEALTHCARE FACILITIES
In 2006-2010, U.S. fire departments responded to an estimated average
of 6,240 structure fires in or on health care properties per year.
These fires caused an average of six civilian deaths, 171 civilian
injuries and $52.1 million in direct property damage annually. Almost
half (46%) were at nursing homes, and almost one-quarter (23%) were in
hospitals or hospices. Cooking equipment was involved in three out of
five (61%) fires; dryers were involved in 7%, 6% were intentionally set;
another 6% were started by smoking materials, and heating equipment was
also involved in 6%. Only 4% of these fires spread beyond the room of
origin. Causes, circumstances, and extent of fire spread varied by
occupancy.
This graphic provides estimates of fire frequency and associated
losses for reported fires in: all health care properties; in nursing
homes; in hospitals or hospices; in mental health facilities caring for
those with developmental disabilities, mental retardation, mental
illness or substance abuse issues; and in clinics or doctors’ offices.
Estimates were derived from NFPA’s fire department survey and the USFA’s
National Fire Incident Reporting System (NFIRS).
Introduction to Fire and the Proper Use and Maintenance of Extinguishers
This is The Fire Triangle. Actually, it's a tetrahedron, because there are four elements that must be present for a fire to exist. There must be oxygen to sustain combustion, heat to raise the material to its ignition temperature, fuel to support the combustion and a chemical reaction between the other three elements.
Remove any one of the four elements to extinguish the fire.
The concept of Fire Protection is based upon keeping these four elements separate.
Types of Fires
Not all fires are the same. Different fuels create different fires and require different types of fire extinguishing agents.
Class A
Class A fires are fires in ordinary combustibles such as wood, paper, cloth, trash, and plastics.
Class B
Class B fires are fires in flammable liquids such as gasoline, petroleum oil and paint. Class B fires also include flammable gases such as propane and butane. Class B fires do not include fires involving cooking oils and grease.
Class C
Class C fires are fires involving energized electical equipment such as motors, transformers, and appliances. Remove the power and the Class C fire becomes one of the other classes of fire.
Class D
Class D fires are fires in combustible metals such as potassium, sodium, aluminum, and magnesium.
Class K
Class K fires are fires in cooking oils and greases such as animals fats and vegetable fats.
Some types of fire extinguishing agents can be used on more than one class of fire. Others have warnings where it would be dangerous for the operator to use a particular fire extinguishing agent.
Types of Fire Extinguishers
Water and Foam
Water and Foam fire extinguishers extinguish the fire by taking away the heat element of the fire triangle. Foam agents also separate the oxygen element from the other elements.
Water extinguishers are for Class A fires only - they should not be used on Class B or C fires. The discharge stream could spread the flammable liquid in a Class B fire or could create a shock hazard on a Class C fire.
Carbon Dioxide
Carbon Dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge.
Carbon dioxide can be used on Class B & C fires. They are usually ineffective on Class A fires.
Dry Chemical
Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
Today's most widely used type of fire extinguisher is the multipurpose dry chemical that is effective on Class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on Class A fires.
Ordinary dry chemical is for Class B & C fires only. It is important to use the correct extinguisher for the type of fuel! Using the incorrect agent can allow the fire to re-ignite after apparently being extinguished successfully.
Wet Chemical
Wet Chemical is a new agent that extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the oxygen and fuel elements.
Wet chemical of Class K extinguishers were developed for modern, high efficiency deep fat fryers in commercial cooking operations. Some may also be used on Class A fires in commercial kitchens.
Clean Agent
Halogenated or Clean Agent extinguishers include the halon agents as well as the newer and less ozone depleting halocarbon agents. They extinguish the fire by interrupting the chemical reaction of the fire triangle.
Clean agent extinguishers are primarily for Class B & C fires. Some larger clean agent extinguishers can be used on Class A, B, and C fires.
Dry Powder
Dry Powder extinguishers are similar to dry chemical except that they extinguish the fire by separating the fuel from the oxygen element or by removing the heat element of the fire triangle.
However, dry powder extinguishers are for Class D or combustible metal fires, only. They are ineffective on all other classes of fires.
Water Mist
Water Mist extinguishers are a recent development that extinguish the fire by taking away the heat element of the fire triangle. They are an alternative to the clean agent extinguishers where contamination is a concern.
Water mist extinguishers are primarily for Class A fires, although they are safe for use on Class C fires as well.
Cartridge Operated Dry Chemical
Cartridge Operated Dry Chemical fire extinguishers extinguish the fire primarily by interrupting the chemical reaction of the fire triangle.
Like the stored pressure dry chemical extinguishers, the multipurpose dry chemical is effective on Class A, B, and C fires. This agent also works by creating a barrier between the oxygen element and the fuel element on Class A fires.
Ordinary dry chemical is for Class B & C fires only. It is important to use the correct extinguisher for the type of fuel! Using the incorrect agent can allow the fire to re-ignite after apparently being extinguished successfully.

The Rules for Fighting Fires
Just remember the three A's
ACTIVATE the building alarm system or notify the fire department by calling 911. Or, have someone else do this for you.
ASSIST any persons in immediate danger, or those incapable on their own, to exit the building, without risk to yourself.
Only after these two are completed should you ATTEMPT to extinguish the fire.
Only fight a fire if:
- The fire is small and contained
- You are safe from toxic smoke
- You have a means of escape
- Your instincts tell you it's OK
Fire Extinguisher Use
- It is important to know the locations and the types of extinguishers in your workplace prior to actually using one.
- Fire extinguishers can be heavy, so it's a good idea to practice picking up and holding an extinguisher to get an idea of the weight and feel.
- Take time to read the operating instructions and warnings found on the fire extinguisher label. Not all fire extinguishers look alike.
- Practice releasing the discharge hose or horn and aiming it at the base of an imagined fire. Do not pull the pin or squeeze the lever. This will break the extinguisher seal and cause it to lose pressure.
When it is time to use the extinguisher on a fire, just remember PASS!
Pull the pin.
Aim the nozzle or hose at the base of the fire from the recommended safe distance.
Squeeze the operating lever to discharge the fire extinguishing agent.
Starting at the recommended distance, Sweep the nozzle or hose from side to side until the fire is out. Move forward or around the fire area as the fire diminishes. Watch the area in case of re-ignition.
Fire Extinguisher Inspection
Like any mechanical device, fire extinguishers must be maintained on a regular basis to ensure their proper operation. You, the owner or occupant of the property where the fire extinguishers are located, are responsible for arranging your fire extinguishers' maintenance.
Fire extinguishers must be inspected or given a "quick check" every 30 days. For most extinguishers, this is a job that you can easily do by locating the extinguishers in your workplace and answering the three questions below.
- Is the extinguisher in the correct location?
- Is it visible and accessible?
- Does the gauge or pressure indicator show the correct pressure?
Fire Extinguisher Maintenance
In addition, fire extinguishers must be maintained annually in accordance with local, state, and national codes and regulations. This is a thorough examination of the fire extinguisher's mechanical parts, fire extinguishing agent, and the expellent gas. Your fire equipment professional is the ideal person to perform the annual maintenance because they have the appropriate servicing manuals, tools, recharge materials, parts, lubricants, and the necessary training and experience.
Fire Safety Preparation and Followup
Ensure that your ENTIRE staff has completed their OSHA compliance training. Verify that your OSHA Compliance Officer and/or HR department have properly done the following:
- Have all fire safety alarms, detectors, exit signs, fire doors, emergency lights, etc. Properly inspected by qualified building maintenance staff and/or the local fire department.
- Developed safe emergency evacuation routes and have these posted in readily available areas visible to both staff and patients.
- Have regular fire drills and instruct employees on the use of alarms, extinguishers, and other emergency procedures in your Fire Safety Plan.
- Train with your staff often enough that they feel confident and knowledgeable in the event of an emergency. Fires happen and move quickly. Your staff needs to know how to notify 911, and move themselves and patients quickly and efficiently to a safe location.
