The OSHA-10 certification indicates a level of performance, competence, and professionalism through at least 10 hours of OSHA training. Every OSHA-10 certified worker is given a card from OSHA and should present this during initial meetings. As we know installation is dangerous work and no one wants to worry about injuries with employers or contractors. Violation of these standards can result in delayed, unorganized projects. These training sessions teach workers all the ins and outs of accident reporting, ladder safety, wearing PPE, as well as employing general safety practices.
