What is an important step when working in environments with flammable materials?

In environments that contain flammable materials, bonding and grounding the workspace is crucial for ensuring safety. This process involves connecting conductive materials together and establishing a path to the ground to prevent the buildup of static electricity, which can ignite flammable vapors or dust.

By effectively bonding equipment and grounding it, the risk of creating sparks or arcs is minimized, creating a safer workspace. This is especially important in industries such as electrical work, where the handling of equipment and materials can produce static charges.

The other options may not effectively address the safety concerns associated with flammable environments. Ignoring static electricity can lead to dangerous situations, while heavy insulation does not necessarily mitigate the risk of ignition from static discharge. Using dry cleaning chemicals may not be relevant to preventing ignition and could introduce additional hazards if those chemicals are also flammable. Thus, ensuring proper bonding and grounding is the best practice in such environments.
