What is a precaution to take when working with flammable materials?

Using grounding techniques is critical when working with flammable materials because it helps prevent static electricity buildup, which can ignite flammable vapors. When flammable substances are moved or handled, they can generate static charges that, if not properly managed, could create sparks capable of igniting these materials. Grounding provides a direct path for the electricity to dissipate safely into the ground, significantly reducing the risk of a fire or explosion.

In contrast, storing flammable materials in open containers increases their exposure to potential ignition sources and disperses vapors into the air, heightening the risk of fire. Similarly, wearing synthetic clothing is discouraged since many synthetic fabrics can ignite easily and contribute to the spread of flames. Keeping flammable materials near heat sources is also unsafe because heat can raise the temperature of the materials and potentially lead to combustion. Therefore, grounding techniques are essential for ensuring safety when handling flammable substances.
