As a subcontractor to Wyle Laboratories, CSS provides staff support to NASA's Johnson Space Center (JSC) Environmental Health Program. Our services include environmental surveillance, Environmental Health Laboratory operations, occupational health training, emergency response support, and asbestos surveys/assessments. Environmental surveillance activities include potable and ground water monitoring and storm water monitoring. Soil and hazardous wastes are sampled as requested. We staff and operate an onsite Environmental Health Laboratory (EHL) that is American Industrial Hygiene Association (AIHA) accredited and conforms to the National Environmental Laboratory Accreditation Program (NELAP). The EHL supports JSC, Ellington Field, White Sands Testing Range, and the Sonny Carter Training Facility by performing chemical and physical analyses of industrial hygiene, environmental, and breathing gas samples. Our personnel also provide emergency response support, complaint investigations, and construction design reviews. An extensive occupational health training program led by CSS reaches more than 10,000 students each year through online and instructor-based classes covering asbestos, bloodborne pathogens, ergonomics, confined space, hazard communication, hearing conservation, personal protective equipment (PPE), and respirator use. We develop the course materials, conduct the training, and review feedback surveys to make adjustments to the instruction techniques. Our onsite occupational health and industrial hygiene personnel conduct ergonomic training and workplace ergonomics evaluations; site-specific confined space training; site-specific asbestos training; and conduct public health functions, e.g., food inspections of cafeterias and the on-site Child Care Center. Our certified asbestos specialists monitor all asbestos abatement and asbestos disturbance activities; conduct periodic employee exposure and ambient monitoring; perform asbestos inspections; and prepare reports on asbestos-related activities. CSS personnel also respond to all hazardous materials spills, and provide immediate recommendations regarding spill clean-up, personal protective equipment required, and a determination if air sampling is warranted.
