NFPA 10 STANDARD FOR PORTABLE FIRE EXTINGUISHERS 2010 EDITION PDF

Brad Kelechava 7 Comments Fire extinguishers are designed to release a chemical agent that can deplete fires in their incipient stage, just following ignition. Eliminating a fire at its source before it reaches near-implacable levels is crucial. Therefore, the confidence that fire extinguishers are both readily available and can function reliably is a prime consideration for preventing property loss, injury, and even death. This type of assurance derives from the proper maintenance, inspection, selection, installation, recharging, and testing of portable fire extinguishers, a series of activities that have long been aided by the use of NFPA

Brad Kelechava 7 Comments Fire extinguishers are designed to release a chemical agent that can deplete fires in their incipient stage, just following ignition. Eliminating a fire at its source before it reaches near-implacable levels is crucial. Therefore, the confidence that fire extinguishers are both readily available and can function reliably is a prime consideration for preventing property loss, injury, and even death. This type of assurance derives from the proper maintenance, inspection, selection, installation, recharging, and testing of portable fire extinguishers, a series of activities that have long been aided by the use of NFPA For example, the document states that fire extinguishers, as well as Class D extinguishing agents, should be inspected at least once every month.

At the crux of this shared knowledge and guidance is the classification of fires. Different fires result from varying sources, and thus should be handled accordingly. Class B: burn in flammable liquids, combustible liquids, petroleum greases, oils, alcohols, and flammable gases. Class C: involve energized electrical equipment. Class D: fires in combustible metals, such as magnesium, titanium, zirconium, sodium, lithium, and potassium.

Class K: fires in cooking appliances that involve combustible cooking media, such as vegetable or animal oils and fats. Each class of fire is effectively put out by an extinguisher class with which it correlates, i. However, as with practically everything else produced and standardized, fire extinguishers have expanded in quality as time has progressed. Some of the earliest examples of what would be considered a f ire extinguisher simply shot out water.

During the past century, throughout which NFPA 10 has been consistently revised, the acceptable materials used for fire extinguishers have shifted and been displaced with the knowledge acquired throughout the years. It also includes an assortment of other types in its now-obsolete list, including extinguishers using soda acid, chemical foam, carbon tetrachloride, methyl bromide, and chlorobromomethane CBM , among others. As the needs for fire extinguishers have changed over the years in response to growing industry needs and an ever-expanding body of knowledge, this standard has undergone changes from the previous revision.

The maintenance of hose stations that are used in lieu of extinguishers is now addressed. The fire classification marking system is expanded to include markings for extinguishers rated for Class AC and Class AK, while removing information on obsolete equipment.
