When rubber cement is used or mixed, what must be ensured about the room's ventilation?

When using or mixing rubber cement, ensuring the room's ventilation aligns with the provisions of NFPA 91 is crucial because this standard specifically addresses the need for proper ventilation in areas where flammable vapors and fumes may accumulate. NFPA 91 outlines the design and installation requirements for exhaust systems that remove potentially hazardous air contaminants, thereby reducing the risk of fire and health hazards associated with the inhalation of toxic fumes.

Proper ventilation helps in diluting and removing the harmful vapors emitted from rubber cement, which can create a hazardous atmosphere if not adequately addressed. Following NFPA 91 standards ensures the safety of personnel working in such environments and prevents the buildup of flammable concentrations of vapor. Therefore, adherence to these provisions is essential for maintaining a safe work environment when dealing with volatile substances like rubber cement.
