Construction Risk: Fire Safety and Threat Assessment

Fires can happen anywhere, and construction sites are no exception. Welding, electrical work, and several other common construction tasks create the perfect environment for an accidental fire. While having fire extinguishers placed in strategic locations around the construction site is a good idea, it is not a comprehensive solution. Different classes of fires need the right type of extinguisher. The most common kinds of fires on construction sites are Class A, B, and C.

Class A Fires

Class A fires have multiple sources. Wood, paper, trash, or any other material that results in glowing embers can all start Class A fires. The best extinguisher to put out this type of blaze is a Class A or Class ABC extinguisher. Class A extinguishers utilize water so construction workers should only use them on Class A fires. For example, using Class A extinguishers on a gasoline-based fire can spread the flames while using it on an electrical fire can result in electrocution. Class ABC extinguishers contain a pressurized, dry, powdered chemical that construction workers can use on Class A, B, or C fires. This versatile extinguisher is preferable over distinct classes because there will be no confusion during the commotion of a fire.

Class B Fires

This class of fire is the result of flammable liquids and gasses. Some examples include gasoline, grease, paint thinners, etc. To put out this type of flame safely, construction workers can use a Class B or Class ABC extinguisher.

Class C Fires

Energized electrical equipment cause these kinds of fires. Construction workers should use a Class BC or Class ABC extinguisher to snuff out this kind of fire.

Additional Important Fire Extinguisher Safety Tips

Knowing what kind of extinguisher goes with which class of fire is only the first step to proper fire safety. There are several more points beyond syncing extinguishers to fires; these include:

  • Knowing the locations of all extinguishers and how to use them
  • Clearing the immediate area around extinguishers of debris and obstructions for ease of access
  • Inspecting, maintaining, and caring for extinguishers

Lastly, construction workers should only use fire extinguishers for putting out fires. Horseplay can result in injuries and is a waste of a valuable fire safety tool. Supervisors should discuss the importance of fire safety and provide proper training for all construction workers to ensure a safe working environment.
