Quality control in occupational safety and health.

An important part of OSHA's responsibilities is the maintenance of quality control methods in occupational health and safety. OSHA and the Bureau of Mines now share the responsibility for the testing and certification of personal safety equipment, and have replaced older and less thorough methods of testing and certifying. Title 30, Code of Federal Regulations, Part II (or 30 CFR II) now requires a documented quality control system for all types of equipment. Thirty CFR 11 also mandates incoming, in process, and final inspection of a product, and the classification of defects and inspection instructions for all components. Gauge calibration, quality control record keeping, and other activities are also required. NIOSH makes periodic visits to the manufacturers to determine compliance with quality control procedures. NIOSH also takes products off the shelf and tests them. However, the problems of feasible sample sizes and the frequency of drawing them has not yet been established. OSHA also sends inspectors into manufacturing factories to take samples for the detection of airborne contaminants. The samples are given to subcontracting laboratories whose quality is monitored by its Morgantown Lab, which offers them samples of known contaminant composition. The variation of results received is then used to prepare control charts for each laboratory so that proper quality control can be maintained. Quality control techniques are also used in the analysis of health problems. Drift detection, detection of differences between analysts, and the accurate determination of calibration intervals have proven helpful in solving health problems. Meetings with companies, investigation of their quality systems, subsequent policy formulation meetings and the preparation of a document outlining federal requirements constitute the heart of OSHA's procedure for instituting quality control at industrial factories.
