To comply with OSHA standards for portable extinguishers, employers must use OSHA-approved fire extinguishers, stay up to date with regulation inspections, provide annual fire extinguisher training for employees and ensure that extinguishers are readily accessible and clearly marked.
Refer to your state and local codes for local fire extinguisher requirements.
*Travel distance is the distance an employee has to walk to reach the fire extinguisher. It is measured down the center of the natural walking path, including curves around corners, walls and doors.
The travel distance for a Class C fire extinguisher is determined by the A or B hazards present. For offices and warehouses with ordinary combustibles, a Class C extinguisher may need to follow Class A distance standards. If flammable liquids are present, the Class B travel distance must be followed.
There are four kinds of inspections that should be conducted.
Be sure that alternate fire protection equipment is available while extinguishers are under inspection and maintenance. After the maintenance inspections, approved extinguishers will receive a dated tag and are good for one year from that date.
