Fire Safety and your NFPA 704 Door Sign

NFPA Hazard Ratings

Northeastern University’s laboratory doors are posted with emergency information to warn occupants and The Boston Fire Department (BFD) personnel of the presence and identification of hazardous materials inside each laboratory.

The National Fire Protection Association (NFPA) has developed a system for indicating the health, flammability, reactivity and special hazards for many common chemicals through use of the NFPA 704 Diamond. The laboratory hazard rating is determined by looking at all the chemicals, gases and special lab uses and generating a rating for each hazard category based on established criteria.

Please read the rating information in each category, take an inventory of your laboratory, and rate each category accordingly. To look up a rating for a particular chemical click on the link at the bottom of the page.
