Major changes in the 2011 NFPA 45 help you reduce fire and explosion risks in laboratories using chemicals.
Essential to the fire safe design and operation of instructional, educational, and industrial laboratories using chemicals, NFPA 45: Standard on Fire Protection for Laboratories Using Chemicals outlines the maximum allowable quantities of liquids and gases, as well as requirements for laboratory ventilating systems and chemical fume hoods.
Revisions impact the design, construction, and operation requirements for laboratories in buildings over one story in height.
Height restrictions were added for Class A and B laboratory units, and the fire resistance rating of laboratory units. Height restrictions and quantities of hazardous materials were modified for laboratory units depending upon the height of the building containing the laboratories.
Other key changes in the 2011 edition:
- Added requirements for laboratories in health care facilities, previously covered in NFPA 99.
- Quantified limits for hazardous materials that could present an explosion hazard -- for storage or use in a laboratory work area
- Clarified requirements for the management of time-sensitive chemicals
