In order to manage risks posed by high-hazard activities performed by GZA subcontractors, GZA has instituted a subcontractor health and safety prequalification process. The activities your company may perform could expose your personnel to hazardous chemicals or wastes in the performance of their tasks. Therefore, requirements up to, and possibly including, OSHA standard 29 CFR 1910.120 (entitled Hazardous Waste Operations and Emergency Response) may be applicable to subcontractor services. Your company is required to recognize and comply with any OSHA or other regulatory requirements applicable to their services.
