What is one of the major hazards found in illegal methamphetamine labs?

Flammability is a significant hazard in illegal methamphetamine labs due to the volatile chemicals involved in the production process. Many of these substances are highly flammable and can create explosive atmospheres, especially when exposed to heat or open flames. The presence of various chemical reactions and the use of solvents further elevate the risk of fire and explosions, making it critical for responders to be aware of these dangers when approaching or handling situations involving such labs.

While other hazards like electrical fires, structural collapses, and water contamination are indeed concerns, they often arise from the unsafe conditions and poor standards commonly found in such illicit operations. The immediate and acute risk of fire and explosion caused by the flammable nature of methamphetamine precursors and by-products makes flammability a paramount concern in these environments.
