The purpose of the Dangerous Gas Program is to provide guidelines that will promote safe and healthy environment for researchers, building occupants, or emergency responders (exposure or gas leak events) by establishing minimum standards and safe practices that will reduce the likelihood of accidental release of dangerous gas.
Gases with any of the following characteristics will fall under the Dangerous Gas Program:
- Pyrophoric (self-igniting) or dangerously reactive gases
- Gases with a National Fire Protection Association (NFPA) health hazard rating of 3 or 4
- Gases with an NFPA health hazard rating of 2 and poor physiological warning properties
- Extremely low occupational exposure limits in the absence of an NFPA health rating
