This manual is not intended to satisfy or to be a substitute for the safety and health requirements of federal, state, or local regulatory agencies. Appropriate regulations and laws should be consulted and followed. The program described in this manual has been developed to meet the specific needs and challenges of the industrial sand industry for surveillance of exposure to crystalline silica. It is not intended to be an occupational health program (OHP) for exposure to crystalline silica in other industries, since parts of this program may not be well suited to other industries and elements of an appropriate program specifically aimed at another industry may not be included in this program.
The scope of this program is purposely limited to surveillance of exposure to respirable crystalline silica. It does not address the corrective measures, such as engineering and administrative controls, that are necessary when exposures approach or exceed acceptable limits. The National Industrial Sand Association (NISA) has prepared for its member companies other information sources on control measures applicable to the industrial sand industry, which supplement this manual. In addition to the assessment of crystalline exposure and medical assessment of silicosis covered in this manual, the other elements of the NISA Silicosis Prevention Program include: commitment of the member company to the program and the goal of eliminating silicosis, control of exposures through engineering and administrative measures or the use of personal protective equipment, involvement of workers in the prevention aspects of the program, and implementing a smoking cessation program as part of an inclusive respiratory program to prevent smoking-related lung diseases. More importantly, the environmental and medical programs described in this manual must not be considered total programs. Other stresses such as noise, heat, radiation, non-silica-bearing dusts, chemical contaminants, and other site-specific conditions, although obvious elements of a total occupational health program, are beyond the intended coverage of this program.
