E-cigarettes and vaporizers can pose an explosion and fire hazard depending on the quality of the product manufacturing and after-market batteries and accessories. As with all electrical and electronic appliances, SUNY New Paltz requires an Underwriters Laboratories certification (UL Listing) for e-cigarettes and vapes. Lithium Ion batteries are often produced in unregulated countries and shipped to the U.S. without the necessary safety certifications, including counterfeit UL hologram labels. The United States Fire Administration has produced guidance related to e-cigarette safety which can be found here.
