Final answer:
It is generally recommended to keep open flames or spark producing devices at least 20 feet away from spray booths to prevent fire hazards, tie back loose clothing, and be aware of fire safety equipment.
Step-by-step explanation:
When working near spray booths, it is essential to maintain a safe distance with any open flame or spark producing devices to prevent a fire hazard or explosion. While exact distances can vary based on local regulations and the design of the spray booth, a commonly advised safety practice is to keep these potential ignition sources at least 20 feet away from spray booths. As a precaution, one should always tie back all loose hair and clothing, follow instructions for igniting an open flame carefully, never leave an open flame unattended, and be aware of the location of fire safety equipment such as fire extinguishers and eyewash stations in the laboratory.
