What must be provided to prevent the accumulation of hazardous flammable vapors?

Providing proper ventilation is essential in preventing the accumulation of hazardous flammable vapors. Ventilation systems work by circulating air and reducing the concentration of flammable vapors in the air, thereby lowering the risk of fire or explosion. Adequate ventilation can help to dilute vapors, move them away from ignition sources, and maintain a safe environment for workers.

Excessive lighting does not address the specific issue of flammable vapors and may not impact their accumulation or potential ignition. Pneumatic tools are used for various construction and maintenance tasks but are not designed to manage air quality or vapor levels. Heating systems, depending on their operation, might even introduce additional hazards if flammable vapors are present, as they could create ignition sources. Thus, proper ventilation stands out as the vital measure for safety against the risks associated with flammable vapors.
