Michigan HB5951 Would Restrict Law Enforcement Use of Chemical Agents and Kinetic Energy Projectiles
In May 2026, Michigan lawmakers introduced HB 5951 to tightly restrict when police may use chemical agents and less-lethal kinetic projectiles for crowd control and to impose detailed incident-level reporting obligations on law enforcement agencies. Although the bill targets law enforcement operations rather than product manufacturers, it underscores growing scrutiny of riot-control chemicals and munitions that could influence procurement choices, liability exposure, and ESG expectations for suppliers serving the Michigan market.
United StatesMinnesota Adopts Law Requiring Disclosure of Chemical Irritant Use in Buildings
Minnesota has enacted a new law requiring law enforcement agencies to notify building owners and relevant occupants when chemical irritants are deployed indoors and to disclose product details for chemical irritants, smoke screens, and diversionary devices used in buildings. This strengthens transparency and risk management for property owners, tenants, insurers, and remediation contractors, and will require updated incident reporting, communication, and cleanup protocols ahead of the law’s expected August 2026 effective date.
United StatesMinnesota Legislature Passes H.F. 3782 on Disclosure of Chemical Irritant Use in Buildings
In April 2026 the Minnesota Legislature passed HF 3782, a bill requiring law enforcement to disclose when chemical irritants, smoke screens or diversionary devices are deployed inside buildings and to use a standard notification form. If enacted, this will increase transparency around chemical exposures for building owners, tenants, insurers and remediation contractors, and may prompt changes in incident response, contracts and insurance practices where such tactics are used.
United StatesMinnesota Public Safety Omnibus Bills Would Require Disclosure of Chemical Irritant Use Inside Buildings (SF4760/HF3990)
In April 2026, Minnesota lawmakers advanced omnibus public safety bills (SF4760/HF3990) that would require law-enforcement agencies to notify building owners and occupants whenever chemical irritants, smoke screens, or diversionary devices are deployed inside buildings, and to share product names, product numbers, and quantities on request. If enacted, these measures would increase transparency after chemical deployments, give building owners, insurers, and remediation contractors better information for clean-up and liability management, and signal higher expectations for incident documentation and disclosure practices by public safety agencies.
United StatesMinnesota Senate Rules Committee Hearing on SF 4144 Chemical Irritant Disclosure Set for 20 April 2026
The Minnesota Senate Rules Committee has scheduled an April 20, 2026 hearing that includes SF 4144, a bill requiring disclosure when chemical irritants are used inside certain buildings. This additional committee step indicates the proposal is continuing to advance, so Minnesota law enforcement agencies and building stakeholders should monitor its progress and be ready for new disclosure and record-keeping obligations if it is enacted.
United StatesMinnesota Senate Advances Bill Requiring Disclosure of Chemical Irritants Used in Buildings
In mid-April 2026 the Minnesota Senate Finance Committee advanced SF 4144, a bill to create new section 626.745 requiring law enforcement agencies to notify building owners and occupants and disclose the specific chemical irritants and diversionary devices used during operations inside buildings. If enacted, this would formalise post-incident notification and product-identification rights for property owners, tenants, insurers, and remediation contractors, improving transparency and enabling better management of health, cleaning, and liability risks after tear gas or similar deployments.
United StatesIllinois SB4045 Would Prohibit Lachrymatory Agents And Require Approval Of Pepper Spray Formulations
Illinois Senate Bill 4045 would ban most uses of tear gas and other lachrymatory agents in Illinois, require state approval of pepper spray formulations, and create new reporting, database, and enforcement mechanisms for chemical irritants. If enacted, this would fundamentally change law enforcement crowd-control options and the state’s pepper spray market, forcing reformulation, new IDPH rulemaking, and heightened liability and data transparency for chemical agent deployments.
