This module we learn Risk Management and wanna share some interesting to you all. During a fire drill, a safety officer want to demonstrate the use if fire extinguisher and therefore he wanted to create a small fire in the metal container. Of course to light up a fire you need oil. So he use petrol. The one which used for cars. The moment he throw the light down into the container, the fire flash back to him and to his back. Petrol is the faster oil to light up cos it can create vapor with fire easily. To use oil during a drill, use diesel. It's not easy to light up and takes some time to fully light up.
