Justrite Type 1 Nonmetallic Safety Cans constructed of high density polyethylene and stainless steel hardware, offer distinct advantages over steel models. They are inert so they stand up to tough acids and corrosives as well as heat. Poly can are dent, puncture and chip resistant. All Justrite nonmetallic cans are designed and manufactured with a unique conductive current-carrying carbon insert imbedded into the rib of the container, completing a ground path between the cover assembly and the flame arrester in the spout. When used with a grounding strip, this provided proper grounding and prevents the creation of an arc during filling or pouring. All Justrite Nonmetallic Type 1 Cans are FM approved.
