Statistical analysis OSHA statistics

It replaces the American National Standard for Uniform Record Keeping for Occupational Injuries and Illnesses, ANSI Z16.4-1977, and USA Standard Method of Recordkeeping and Measuring Work Injury Experience, ANSI Z16.1-1967. This standard is a development of the old Z16.1, which had been in use since 1937, before it was replaced by the (for injury and iUness statistical research) Occupational Safety and Health Administration (OSHA) system. The standard is useful in determining what kinds of events to evaluate. It includes statistical tools, including control charts, for data analysis. 

The OSH Act mandated the Secretary of Labor with responsibility for developing and maintaining a national system for collection and analysis of work injury and illness statistics. In 1971 (the initial year that the OSH Act took effect), the Secretary of Labor delegated this responsibility to the Bureau of Labor Statistics (BLS), within the Department of Labor. Since that time BLS has performed a national Annual Survey of Occupational Injuries and Illnesses, while OSHA has retained responsibility for enforcing compliance with the recordkeeping provisions of the Part 1904 of the OSHA regulations. 

The act requires the secretary to develop and maintain an effective program of collection, compilation, and analysis of occupational safety and health statistics. 29 CFR 1904, Recording and Reporting Occupational Injuries and Illnesses, requires employers to record information on the occurrence of injuries and illnesses in their workplaces. The employer must record work-related injuries and illnesses that meet one or more of certain recording criteria. OSHA rules found in 29 CFR part 1904 require all employers with 11 or more employees to keep OSHA injury and illness records, unless classified in a specific low-hazard industry. Employers with 10 or fewer employees must keep OSHA records, if OSHA or the Bureau of Labor Statistics informs them in writing that they must keep records. Employers may use the OSHA 301 or an equivalent form that documents the same information. Some state workers compensation, insurance, or other reports may be acceptable substitutes, as long as they provide the same information as the OSHA 301. The OSHA Log of Work-Related Injuries and Illnesses (Form 300) serves as a means to document and classify work-related injuries and illnesses. The log also documents the extent and severity of each case.
