This testimony before the Senate Committee on Labor and Public Welfare reviewed the efforts of NIOSH to increase awareness of occupational safety and health problems on the part of employers across the United States. Programs have been developed to assist to a great degree the small business employers and employees since more than 87 percent of the nation's businesses employ 25 or fewer employees, representing over 14 million workers. The conducting of health hazard evaluations was one of the primary types of assistance offered. NIOSH visited a work site at the request of an employer or employee representative to determine potentially toxic elements at that site. NIOSH has responded to nearly 600 such requests since the program was established in 1971. Once an evaluation was completed, NIOSH notified the employer or employee representative and OSHA of the results and made recommendations for controlling the existing hazards. On site safety and health consultation was also provided, directed specifically toward aiding small businessmen in recognizing, evaluating, and controlling potential safety and health problems in the workplaces. Health and safety guides have been developed which meet the needs of specific businesses such as retail bakeries, service stations, metal stamping operations, and wooden furniture manufacturers. These guides were available to trade associations and individual establishments.
