Notice one: Adequately ventilated for every NFPA 497 usually means a ventilation price that affords both six air variations for every hour, 1 cfm per square foot of floor area, or Yet another very similar criterion that prevents accrued vapor-air read more concentrations from exceeding 25% in the reduced flammable Restrict.
