>First, fire is fast, hot and deadly. When a fire breaks out, there is little time to think or react. We need to know right away what to do and then take all the steps required to contain the fire and manage the situation.
>Second, three elements are required to create and sustain fire: flammable material, oxygen and an ignition source. Fire is essentially a chemical reaction between fuel and oxygen triggered by a heat source. Knowing these elements is useful because removing, containing or controlling any one of them can prevent a fire.
>The most manageable fire is one that is prevented. Prevention, however, requires us to be aware of many potential ignition sources. Here is a list to help you identify areas of concern.
- overloading electrical power outlets
- positioning electrical heaters incorrectly
- leaving appliances on when not in use
- removing plugs from outlets before turning off appliances
- placing power cords under carpets or in traffic areas using damaged wiring and plugs
- providing poor maintenance, which can lead to overheating and excessive power draw
- placing machinery in congested areas, among other equipment or surrounded by flammable materials
- disregarding oil leaks, drips and spills
- using heating tools in a workshop where combustible materials are present
- lacking appropriate electrical grounding and ground fault protection systems
- allowing chemicals to mix as a result of poor storage, spills or leaks
- keeping pool chemicals, cleaning solutions, solvents, gasoline or paints in unsafe or uncontrolled areas
- keeping excessive amounts of oil-soaked rags in one place
- leaving lids off volatile products
- allowing large amounts of decaying organic materials to collect in an uncontrolled space
- smoking, especially in areas of concern
- disposing hot ash in garbage bins
- packing or storing together combustible materials
- allowing messy and cluttered workspaces
- being ignorant
- storing more oxygen or flammable liquids in one location than necessary
- placing oxygen and flammable gas cylinders on hot surfaces or in a hot environment
- servicing, connecting, transferring or using oxygen in areas that contain heat sources or are not oxygen-clean
- using faulty equipment
- allowing smoke, welding, brazing or open flames near flammable gas cylinders or liquids
- providing insufficient ventilation in rooms where oxygen or flammable gases or liquids are used or stored
>While prevention is key, being aware, prepared, trained and equipped will ensure the best possible outcome in a fire. Do not try to be brave; if you are unsure, untrained or responsible for others, evacuate, and leave the firefighting to the professionals.
