Airborne Contaminants

Chapter 296-841, WAC

All updates for this rule:

Airborne Contaminants (Chapter 296-841 WAC); Permissible exposure limits of air contaminants (WAC 296-307-62625)

The purpose of this rulemaking is to prevent worker exposure to respirable crystalline silica. This rulemaking is in response to Occupation Safety and Health Administration (OSHA)’s final rule on respirable crystalline silica for general industry/maritime and construction. Respirable crystalline silica is currently included in the Department’s air contaminant standard under chapter 296-841 WAC and chapter 296-307-62625 WAC (and other standards that reference these requirements). OSHA issued a final rule to curb lung cancer, silicosis, chronic obstructive pulmonary disease and kidney disease in America's workers by limiting their exposure to respirable crystalline silica. The rule is comprised of two standards, one for Construction 29 CFR 1926 and one for General Industry/Maritime 29 CFR 1910. Both standards become effective June 23, 2016, after which industries have one to five years to comply with most requirements depending on the type of work performed. Since this final rule imposes additional or more stringent requirements on employers than existing OSHA standards, State Plans must adopt an “at least as effective” standard or amendment to their existing standards, or show that they already have an existing “at least as effective” standard. As an OSHA-approved State Plan, the Department is the primary entity to regulate this subject in Washington, with certain exceptions pertaining to the maritime industry and U.S. government operations, in which cases OSHA maintains jurisdiction.768.
