Do chemical storage cabinets need to be ventilated?
The National Fire Protection Association (NFPA) does not recommend the ventilation of flammables cabinets. (See page 906 of the Flinn Scientific Catalog/Reference Manual.) Instead of ventilating individual chemical safety storage cabinets, we suggest you ventilate your entire chemical storage area a minimum of four air changes per hour. This type of ventilation system will provide needed ventilation for all chemicals. The best type of vent fan and how it should be installed can be found on page 958 of the Flinn Scientific Catalog/Reference Manual.
