A fire on a construction site can result in serious injuries and loss of materials, equipment and even lives. All employees need to be familiar with the jobsite’s fire protection program – who to contact, what to do, the various types of fire extinguishers and their locations throughout the jobsite. Employees should be trained in the use and limitations of fire extinguishers to ensure they are used effectively when needed.

Fire extinguishers are meant to handle only small fires. If a fire becomes too large or the environment becomes too dangerous, employees should evacuate the area.

  • The fire is too large.
  • The air is unsafe to breathe.
  • The environment is too hot or the smoke limits visibility.
  • Evacuation paths are impaired.

Keep the fire in front of you. Never place yourself where the fire obstructs your escape.

  • A Wood, paper, ordinary trash.
