For a fire to happen, the following elements are essential • • Oxidiser to sustain combustion. • Heat to reach ignition temperature. • Fuel or combustible material. This results in a chemical chain reaction which starts a fire. Removing any of these elements will extinguish the fire. Service portable fire extinguishers at least once a year, or when the monthly inspection indicates servicing is necessary. Keep written records showing maintenance items such as serial number and type of extinguishers, location, inspection date, description of tests, date of next inspection, date of annual servicing, comments and inspector’s.

The NFPA requires inspection of your extinguisher every month. During this check a Cintas technician will visually inspect the unit, clean, check pull pin as well as provide documentation of the inspection. Annual Maintenance. An inspection of each of your extinguishers is often required by NFPA or the local AHJ.   When it comes to fire safety, making sure your home or workplace is prepared with the right type of fire extinguisher is a big deal. It’s a great precaution to take and, for smaller or containable fires, extinguishers can help to put them out or to mitigate a more serious situation until the fire department arrives.

FIRE SAFETY LECTURE NOV FIRE SAFETY • Fire is a form of a chemical reaction that involves the rapid oxidation of combustible fuel (material) with the subsquent liberation of heat and light. Types of fire As far as safety is concerned, there are two types of fire; a) controlled (safe) fire. chemical stored pressure extinguishers manufactured prior to October shall be removed from service at the next 6-year maintenance interval or the next hydrotest interval, whichever comes first.” In the late s, UL, along with the NFPA 10 committee and fire extinguisher manufacturers, conducted a series of fire tests with novice operators.

A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations.

It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire brigade.

The fire is the first major hazard in the chemical / process industries and causes more serious accidents than explosions or toxic release, although the accidents in which the greatest loss of life and the damage occur are generally caused by explosion.

Fire is normally regarded as having a disaster potential less than explosion or toxic release. ( ILCS 25/6) (from Ch. 1/2, par. 6) Sec. Investigation and record of fires; Office of the State Fire Marshal.

(a) The chief of the fire department shall investigate the cause, origin and circumstances of every fire occurring in a municipality or fire protection district, or in any area or on any property which is furnished fire protection by the fire department of such municipality.

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.

In terms of labeling requirements under the Hazard Communication Standard (HCS), only those fire extinguishers that contain hazardous chemicals are required to be labeled.

A compressed gas is defined as a physical hazard in the HCS. Therefore, those fire extinguishers containing compressed gas are required to be labeled under the HCS. Also called a fire extinguisher inspection form, it allows inspectors to record details about the fire extinguishers and other observations such as the exact location and its current condition.

Fire extinguisher checklists help inspectors proactively identify signs of issues that may render extinguishers unfit for use in an actual emergency. Fire and Explosion Investigation.

From the corner office to our labs and out into the field, our level of expertise, experience and track record in fire investigation is staff includes professionals who have investigated fires for over 40 years and even some who have commanded large metropolitan bomb squads before coming to S-E-A.

#7) Electrical Contact: Never use Class A fire extinguishers (or other sources of water) to extinguish energized power sources. Miscellaneous Considerations: Prior to operating fire extinguishers personnel must be trained by an authorized college trainer. When fighting a fire, sound the fire alarm and call the fire department, as appropriate.

Fire and Explosion Hazards This course provides employees with basic knowledge of the dangers associated with fires and explosions, as well as appropriate planning and training for these events.

The course will review fire basics, chemistry of combustion, explosions, common workplace hazards, and what to do in case of a fire or explosion. Preventive Fire & Safety Equipment, Inc.

Old Dixie Highway, #5 Lake Park, Florida Dear Mr. Trafelet: Thank you for your letter of Aug requesting an interpretation of the Hazard Communication Standard (HCS) (29 CFR ) requirements for labeling fire extinguishers.

The issues you raised and our responses are. Safety and Risk Management Montana State University P.O. Box Bozeman, MT Tel: () Fax: () Physical Address. 1 Uniformly spaced standpipe systems or hose stations connected to a sprinkler system installed for emergency use may be used instead of Class A portable fire extinguishers.

2 Depending on size of extinguisher and size of fire hazard, a maximum 30 feet travel distance may be required. 3 Use existing Class A or Class B hazards to determine the required pattern.

The combination of effective fire detection and protection systems, fire extinguishers and proper training is more than sufficient to reduce any risks associated with both fire and dry chemical. Fire extinguishers perform a necessary and life-saving function, but breathing the chemicals used may cause some health problems.

To use a fire extinguisher safely, you should recognize the potential health effects of the fire fighting chemicals. Carbon dioxide at 34 percent concentration is lethal.

ever turn your back to fire. Renew attack when indicated. Promptly report use of extinguisher. If not re-charged, potential for serious fire. Always check extinguisher after use and have it re-charged and put back in service immediately. Take extinguisher out of service and have it re-charged.

Developed By: 1. Reviewed By: 1. The handbook provides ready information on the fire and chemical reactivity of commonly used chemicals. Its purpose is to provide basic information important to the safe handling of chemicals and to help provide guidance in responding to a hazardous materials incident, in particular, incidents involving reactive chemicals and materials posing fire and explosion hazards.

Fire extinguishers contain different chemicals, depending on the application. Handheld extinguishers, which are commonly sold at hardware stores for use in the kitchen or garage, are pressurized.

Class D extinguishers are recommended on burning metal. Class D fire extinguishers are not used on any other class of fire. The material in a Class D extinguisher is a foam prod-uct that puts out the fire by replacing the oxygen near it.

Class D fire extinguishers are the most expensive. Class D extinguishing equipment is marked with a yellow.

In addition, employers must provide "alternate equivalent protection when portable fire extinguishers are removed from service for maintenance and recharging," according to 29 CFR (e)(5). This information applies to portable fire extinguishers. General The provisions of this policy apply to the selection, distribution, inspection, maintenance and testing of portable extinguishing equipment.

The requirements given herein are minimums. Portable extinguishers are intended as a first line Continued.Division of Fire Safety Fire investigators, who are Missouri POST licensed law enforcement officers, are on call 24 hours a day, seven days a week.

They are stationed throughout the state and respond to requests for assistance from local fire departments and law .Because a weakened fire extinguisher poses the threat of failure or explosion upon use, extinguishers that fail hydrostatic tests may not return to service.

The frequency of required hydrostatic tests varies with the extinguisher's type, but dry chemical ABC extinguishers—the most common type—must undergo testing at least every 12 years.
