Fire-Resistant Materials Applicators


The Department of Labor & Industries (L&I) is conducting rulemaking to update the licensing and training requirements for fire-resistant material applicators. L&I initiated rulemaking on February 6, 2024.

See all the rulemaking activity for fire-resistant material applicators on our L&I Rulemaking page.

Learn more about our rulemaking process and terminology.


L&I’s Division of Occupational Safety and Health (DOSH) is required to implement and enforce Substitute House Bill (SHB) 1323, passed by the Washington State legislature in the 2023 session. SHB 1323, codified under chapter 49.105 RCW, requires a training and certification program be created for individuals who apply fire-resistant materials and provides for enforcement. The training must be provided by an apprenticeship program registered with the Washington State Apprenticeship and Training Council, fire-resistant material manufacturers, or other certified training providers approved by DOSH.
