NFPA 45 Standard on Fire Protection for Laboratories Using Chemicals
NFPA 45 化學(xué)實(shí)驗(yàn)室消防標(biāo)準(zhǔn)
1.1.1 This standard shall apply to laboratory buildings, laboratory units, and laboratory work areas whether located above or below grade in which chemicals, as defined, are handled or stored.
1.1.2 This standard shall not apply to the following
(1)* If conditions (a) and (b) exist, this standard shall not apply (a) Laboratory units that contain less than or equal to 4 L (1 gal) of flammable or combustible liquid (b) Laboratory units that contain less than 2.2 standard m3 (75 scf) of flammable gas, not including piped-in low-pressure utility gas installed in accordance with NFPA 54, National Fuel Gas Code
(2) Laboratories that are pilot plants
(3) Laboratories that handle only chemicals with a hazard rating of zero or one, as defined by NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response, for all of the following health, flammability, and instability
(4) Laboratories that are primarily manufacturing plants
(5) Incidental testing facilities
(6) Physical, electronic, instrument, laser, or similar laboratories that use chemicals only for incidental purposes, such as cleaning
(7) Laboratories that work only with radioactive materials, as covered by NFPA 801, Standard for Fire Protection for Facilities Handling Radioactive Materials
(8) Laboratories that work only with explosive material, as covered by NFPA 495, Explosive Materials Code
1.1.3 This standard contains requirements, but not all-inclusive requirements, for handling and storage of chemicals where laboratory-scale operations are conducted and shall not cover the following
(1) The special fire protection required when handling explosive materials (See NFPA 495, Explosive Materials Code.)
(2) The special fire protection required when handling radioactive materials
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
Keep laboratory personnel, equipment, and buildings safe with the 2011 NFPA 45. (Softbound, 49 pp., 2011)
