What should always be done before using flammable materials during operations?

Prior to using flammable materials, it is essential to shut off all ignition sources to minimize the risk of fire or explosion. Flammable materials can easily ignite when exposed to sparks, open flames, or even hot surfaces. Eliminating potential ignition sources safeguards the work environment and protects individuals from hazardous situations during operations involving flammable substances.

While wearing safety gear, reading the safety manual, and ensuring proper ventilation are all important safety practices, they do not directly address the immediate risk of ignition that flammable materials present. Ensuring that ignition sources are controlled or eliminated takes precedence in preventing accidents, thereby creating a safer working environment.
