Hazard identification reactive substances

Hazard identification a process to identify hazards and associated risk to persons, property, and structures and to improve protection from natural and human-caused hazards Hazard Identification and Risk Assessment (HIRA) a process to identify hazards and associated risk to persons, property, and structures and to improve protection from natural and human-caused hazards HIRA serves as a foundation for planning, resource management, capability development, public education, and training and exercises Hazard operability study a structured means of evaluating a complex process to find problems associated with operability or safety of the process Hazard rating (NFPA) classification system that uses a four-color diamond to communicate health, flammability, reactivity, and speciflc hazard information for a chemical substance a numbering system that rates hazards from zero (lowest) to four (highest)... 

For companies engaged primarily in the bulk storage, handling, and use of chemicals identification and prevention of reactive hazards, including the inadvertent mixing of incompatible substances. 

NFPA developed Standard 704 as a tool for identification and evaluation of potential hazards during emergency response, not for application to chemical process safety. The instability rating is a part of this standard. It was not intended to be used to measure reactivity, but rather to measure the inherent instability of a pure substance or product under conditions expected for product storage. The instability rating does not measure the tendency of a substance or compound to react with other substances or any other process-specific factors, such as operating temperature, pressure, quantity handled, chemical concentration, impurities with catalytic effects, and compatibility with other chemicals onsite. 

The hazardous waste identification regulations that define the characteristics of toxicity, ignitability, corrosivity, reactivity, and the tests for these characteristics, differ from state to state. In addition, concentration limits may be set out by a state for selected persistent and bioaccumulative toxic substances that commonly occur in hazardous substances. For example, the California Hazardous Waste Control Act requires the California State Department of Health Services (CDHS) to develop and adopt by regulation criteria and guidelines for the identification of hazardous wastes and extremely hazardous wastes.
