Fire Protection on Construction Sites

Originally published 01/24/2018

A fire on a construction site can result in serious injuries and loss of supplies, 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. The information provided below covers some basic fire protection requirements.

  • Train all employees on the jobsite on the jobsite’s fire protection program.
