NFPA45

Help protect life and property from fire hazards in laboratories using chemicals.

NFPA 45, Standard on Fire Protection for Laboratories Using Chemicals, is the industry-trusted source for comprehensive requirements for the fire-safe design and operation of instructional, educational, and industrial laboratories. 

The significantly revised 2024 edition offers current information on the maximum allowable quantities of liquids and gases, laboratory ventilating systems, and chemical fume hoods.

Notable changes include:

  • Expanded the scope to apply to laboratories in health care facilities where any quantity of ignitible (flammable or combustible) liquid is present
  • Added new requirements in Chapters 3, 7, and 11 to address the installation, operation, maintenance, and training necessary for the safe use of ductless chemical fume hoods
  • Revised automatic sprinkler system requirements in Chapter 6 to correlate with the language used in NFPA 13, Standard for the Installation of Sprinkler Systems
  • Revised Chapters 5 and 7 to clarify requirements for a second means of egress from a laboratory work area based on the placement of fume hoods in the laboratory
  • Edited Chapter 11 to address aspects of stored energy hazards as they relate to various laboratory apparatus
  • Added new annex material clarifying sash closure requirements in 11.2.2.1
  • Added annex material in 11.2.6 to clarify when NFPA 51B, Standard for Fire Prevention During Welding, Cutting, and Other Hot Work, would apply in a laboratory setting
  • Made revisions throughout the document to the terms flammable and combustible liquid to align with ignitible (flammable and combustible) liquid terminology updated in NFPA 30, Flammable and Combustible Liquids Code
  • New supplementary definitions added to Annex B S to include the NFPA 30 liquid classification scheme
