CODE A standard that is an extensive compilation of provisions covering broad subject matter or that is suitable for adoption into law independently of other codes and standards. GUIDE A document that is advisory or informative in nature and that contains only non mandatory provision. This may contain mandatory statements such as when it can be used, but the document as a whole is not suitable for adoption into law. Recommended Practice A document that is similar in content and stru...

Absolute Temperature A temperature measured in Kelvins(K) or Rankines(R). Accelerant A fuel or oxidizer, often an ignitible liquid, intentionally used to initiate a fire or increase the rate of growth or spread of fire. Accident An unplanned event that interrupts an activity and sometimes causes injury or damage or a chance occurrence arising from unknown causes; an unexpected happening due to carelessness, ignorance, and the like. Active Fire Protection System A system ...
