This standard shall apply to laboratory buildings, laboratory units, and laboratory work areas whether located above or below grade in which chemicals, as defined in NFPA 704 with one or more of the following hazard ratings are handled or stored: health — 2, 3, or 4; flammability — 2, 3, or 4; or instability — 2, 3, or 4.
This standard shall apply to all educational laboratory units and instructional laboratory units in which any quantity of chemicals, as defined in NFPA 704 with one or more of the following hazard ratings, is handled or stored: health — 2, 3, or 4; flammability — 2, 3, or 4; or instability — 2, 3, or 4.
With the exception of 1.1.2, this standard shall not apply to the following:
(1)*Laboratories for which the following conditions 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 lowpressure utility gas installed in accordance with NFPA54
(3) Laboratories that handle only chemicals with a hazard rating of 0 or 1 for all of the following: health, flammability, and instability, as defined by NFPA 704
(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)*Hazards associated with radioactive materials, as covered by NFPA 801
(8) Laboratories that work only with explosive material, as covered by NFPA 495
(9)*A laboratory work area containing an explosion hazard great enough to cause property damage outside that laboratory work area or injury outside that laboratory work area requiring medical treatment beyond first aid
* A laboratory work area contains an explosion hazard if an explosion of quantities or concentrations of reactive materials could result in serious or fatal injuries to personnel within that laboratory work area. Such quantities or concentrations include, but are not limited to, the following:
(1) Storage of more than 0.45 kg (1 lb) of materials with an instability hazard rating of 4 (see B.2.5)
(2) Use or formation of more than 0.11 kg (0.25 lb) of materials with an instability hazard rating of 4 (see B.2.5)
(3)*Presence of highly exothermic reactions in glass or open reaction vessels involving more than 10 g (0.35 oz) of materials such as polymerizations, oxidations, nitrations, peroxidations, hydrogenations, or organo-metallic reactions
(4) Use or formation in glass or open reaction vessels involving more than 10 g (0.35 oz) of materials whose chemical structures indicate a potential hazard, but whose properties have not been established, such as salts of alkenes, triple bonds, epoxy radicals, nitro and nitroso compounds, and peroxides
(5) Other explosion hazards as determined by a qualified person
In this case NFPA 45 supplemented by appropriate shielding, handling, and similar protective measures does apply.
Alaboratory work area contains an explosion hazard if an explosion of quantities or concentrations of flammable gases or vapors could result in serious or fatal injuries to personnel within that laboratory work area. In this case, NFPA 45 does apply.
This standard contains requirements, but not allinclusive 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.)
(2) The special fire protection required when handling radioactive materials
The purpose of this standard shall be to provide basic requirements for the protection of life and property through prevention and control of fires and explosions involving the use of chemicals in laboratory-scale operations.
This standard is designed to control hazards and protect personnel from the toxic, corrosive, or other harmful effects of chemicals to which personnel might be exposed as a result of fire or explosion.
The goal of this standard shall be to achieve a comprehensive laboratory fire prevention and protection program to prevent injury or death to occupants and emergency response personnel.
The objectives of this standard shall be as follows:
(1) Limit injury to the occupants at the point of fire origin
(2) Limit injury to emergency response personnel
(3) Limit property loss to a maximum of a single laboratory unit
It is not the objective of this standard to address financial losses such as business interruption or property loss when the loss of a laboratory unit is unacceptable.
