At what distance is the space considered a Class I, Division 2 location in a spray booth?

• A. 2 m (6.5 ft)
• B. 1 m (3.3 ft)
• C. 915 mm (3 ft)
• D. 1.5 m (5 ft)

Answer: (C)

In Class I, Division 2 hazardous locations, particularly in environments such as spray booths, the focus is on the presence of flammable liquids or vapors that can create explosive atmospheres during specific conditions. The spacing criteria are established primarily to ensure safety by limiting exposure to potential ignition sources. The correct answer indicates that the area considered a Class I, Division 2 location extends out to 915 mm (3 ft) from the spray application. This distance has been determined based on typical industry practices and safety guidelines, which account for the dispersion of flammable vapors and the concentration levels that could become hazardous. Understanding this distance is essential for the installation of equipment, electrical systems, and protective measures that are compliant with safety standards. It ensures that any potential flammable emissions are adequately addressed to mitigate risks associated with ignition and explosion in the work environment.
