In addition, chloroprene has a high reactivity and should be stored away from oxidizing agents such as perchlorate, peroxides, permanganates, chlorates, nitrates, chlorine, bromine, and fluorine. All activities inducing a potential fire hazard should be avoided. For instance, smoking, having open flames or using sparking tools to open or close storage containers should be prohibited. It is also advised that grounded and bonded metal containers are used for the transport of chloroprene.

OSHA identifies chloroprene as a category 2 flammable liquid and emphasizes that at least one portable fire extinguisher should be within 10 and no more than 25 feet away from the flammable liquid storage area. OSHA provides resources on addressing flammable liquids at industrial plants which is where the likely exposure to chloroprene exists (see external resources). As a vapor, chloroprene is heavier than air.

In 2022, a request made by Denka to regulate chloroprene emissions was rejected by EPA. The request establishes a revision of EPA’s 2010 assessment of the chemical, arguing that the model used to estimate human cancer risk based on experiments, performed on mice, was not rigorous.

The only known environmental effect is related to how chloroprene is volatile and spreads rapidly through the air. This highly flammable component increases the possibility of causing a fire or explosion releasing irritating or toxic fumes (or gases).
