How to practice fire safety at your workplace
Understand the priority.
If there is a fire the main concern is that everyone can reach a safe place quickly. Putting the fire out is the second priority because of the spread of fire, heat and smoke caused by it which can trap.
By law your workplace must have suitable means of detecting, giving warning and escape. During a fire you want to get out as quickly as possible because the fire can trap or overcome you by the heat and the smoke before you get a chance to evacuate.
