Ventilation -
When
Required
U.S. OSHA, 29 CFR, Part 1910, Occupational Safety and Health Standards,
Subpart Z, Toxic and Hazardous Substances,1910.1450,C4(c):
Ventilated storage cabinets, canopy hoods, snorkels, etc. should be provided as
needed. Each canopy hood and snorkel should have a separate exhaust duct.
Local Codes
Some local jurisdictions require bottom venting of flammable liquids storage cabinets.
National Fire Protection Association, Standard NFPA 45, 2011
8.4.8
Special local exhaust systems, such as snorkels or “elephant trunks”, shall have
sufficient capture velocities to entrain the chemical being released.
American Institute of Architects, GUIDELINES FOR PLANNING AND DESIGN OF
BIOMEDICAL RESEARCH LABORATORY FACILITIES 1999
C.14.4 Hazardous Waste Storage and Handling
h. A separate ventilation system shall be installed for the storage room. Exhaust shall
be directed away from the building and the buildings’ air intakes. This ventilation
system shall be connected to the building’s standby power system and contain
appropriate filtration and monitoring devices.
Note that snorkels and canopy hoods should
not be utilized when hazardous or toxic fumes
might be present. These exhaust devices
should only be utilized for non hazardous fume
applications or to remove water vapor, heat or
annoying odors.
Manufacturers of flammable liquid storage
cabinets typically provide plugged vent
connections to accommodate local
requirements for venting.
