+ MSDS and NFPA Safety

National Fire Prevention Association (NFPA) Standard System for the Identification of the Hazards of Materials for Emergency Response “Fire diamond" used by emergency personnel to quickly and easily identify the risks posed by hazardous materials. This helps determine what, if any, special equipment should be used, procedures followed, or precautions taken during the initial stages of an emergency response.

NFPA CHEMICAL HAZARD LABEL HEALTH SPECIAL REACTIVITY (STABILITY) FLAMMABILITY

NFPA CHEMICAL HAZARD LABEL Least Serious 4 Most Serious 40 Flammable vapor which burns readily Substance is stable

NFPA CHEMICAL HAZARD LABEL Avoid water. May detonate with heat or ignition. Severe health risk. Burns readily. Diborane
