What does the 'O' in TOSS indicate for fire extinguishers?

The 'O' in TOSS stands for "Gauge in the green," which is a crucial component of fire extinguisher readiness. This term emphasizes the importance of the pressure gauge being in the green zone, indicating that the extinguisher is fully charged and operational. A gauge reading within this designated area means that the fire extinguisher can effectively be used in an emergency situation, ensuring the safety of individuals attempting to combat a fire.

Maintaining the pressure gauge in the green is vital to ensure that the extinguisher will perform correctly when needed. If the gauge indicates that the pressure is low (in the red zone), the extinguisher may not discharge effectively, posing a significant risk during a fire emergency. Understanding this aspect of fire safety contributes to overall preparedness and effective response to fire incidents.
