The High Hazard list involves industries with high DART(Days away, restricted or transferred) injury rates. Those industry sectors on the list are targeted for programmed inspections. The 2015/2016 list had Framing Contractors, under the NAICS code 23813. Framing Contractors made the list again in 2016/2017. The new entries for construction in 2016/2017 are Masonry Contractors, under NAICS code 23814, and Residential Building Construction, under NAICS code 23611. Code 23611 does not include Specialty Trade Contractors who do subcontract work on residential buildings. It does include Residential Housing General Contractors and For-Sale Builders and Remodelers of residential structures. If you are in one of the three listed industry sectors, you should make sure you are fully prepared in case you get a programmed inspection. The High Hazard Unit of Cal/OSHA is a specialized group who is very thorough in their scrutiny of a business. You can click here to learn more about the High Hazard List by CLICKING HERE.
