WQSi maintains a strict corporate Health & Safety Program designed to reduce the risk/injuries to WQSi staff members, client representatives, site personnel, and the public, as is evidenced by our historical EMR which has always been lower than 0.5. Detailed, site-specific health & safety plans
are prepared for each project. We start each day with a toolbox safety meeting to address the hazards of all the projected work activities. We also address the job activities of other contractors working on the site. All employees are current with their OSHA 10, OSHA 30, OSHA 1910.120 training and first aid and CPR. WQSi has ZERO lost time accidents in the history of the company.
