Explosives Rulemaking: Safety standards for possession, handling, and use of explosives

The Department of Labor and Industries (L&I) is conducting rulemaking related to Chapter 296-52 WAC, Safety standards for possession, handling and use of explosives.

See all the rulemaking activity for Explosives on our L&I Rulemaking page.


L&I filed a preproposal (CR-101) (41 KB PDF) with the Washington State Code Reviser January 23, 2018, to officially begin the rulemaking process. We are currently working with the Explosives Safety Stakeholder group (ESSG) Stakeholder Group to develop the proposed rule language.

Learn more about our rulemaking process and terminology.


This chapter details the requirements for the manufacture, possession, storage, selling, purchase, transportation, and use of explosives, including blasting agents.

Explosives, including blasting agents, are used in many industries: mining, quarrying, construction and demolition, avalanche control, manufacturing, firefighting, local and state law enforcement, entertainment industry, pyrotechnics (fireworks), logging, agriculture, and even medicine to fracture kidney and gall stones.

Many sections of the chapter have not been updated in 10 to 30 years. Changes are needed to reflect current industry best practices and align with federal regulations.

L&I formed an Explosives Safety Stakeholder Group (ESSG) in 2017 in cooperation with explosives industry, government and law enforcement leaders. It is an advisory group for L&I regarding explosives safety, policy, and procedures in Washington. The mission of the ESSG is simple: Keep Washington safe and working — with explosives.

Washington Explosives Safety Stakeholder Group (ESSG) Guidelines

The group meets annually, except during times of code revision (quarterly then). The goal of bringing representatives from business, labor, and state entities, to name a few, is to develop recommendations to update the current occupational explosives standards; and, provide a safe and healthy environment for employees.

Stakeholder meetings and Public Hearings will continue to occur. Meetings are open to the public and will include representatives from business, labor, and government. Meeting dates and locations will be posted on this page.
