Which authority regulates the carrying of tear gas by security officers?

The regulation of tear gas use by security officers falls under the purview of the Bureau of Security and Investigative Services (BSIS). This agency is responsible for overseeing the licensing, training, and conduct of private security personnel in California, which includes regulations about the types of weapons and devices they are authorized to carry. The BSIS ensures that security officers receive proper training on the use of tear gas and understands the legal implications of carrying it. By regulating the carrying of tear gas, the BSIS establishes standards to ensure the safety of both the security officers and the general public, as improper use of such substances can lead to dangerous situations.

Local law enforcement and other agencies may have their own regulations and guidelines regarding the use of such defensive tools, but the primary responsibility for regulating security officer conduct and the specific tools they can use lies with the BSIS. This makes the BSIS the correct authority in this context.
