The recommended NIOSH standards for protecting against injury from chlorine (7782505) are presented along with sections containing the criteria upon which the standards are based--biologic effects of exposure and environmental data. Other sections contain comparisons with previous standards; bases for the recommended exposure limits; safety precautions for the manufacture, storage, transportation, handling and use of chlorine; methods for sampling in air; analysis of air samples; a material safety data sheet; chemical and physical properties of chlorine; occupations with potential exposure to chlorine; recommended alkaline solutions for absorbing chlorine; and a calibration setup for a personal sampling pump with midget bubbler. Criteria data include the extent of exposure, historical reports, case studies on effects on humans, epidemiological studies, animal toxicity and correlation of exposure and effects. Recommendations include a ceiling concentration of 0.5 ppm for any 15-minute sampling period, medical surveillance, labeling, personal protective equipment (protective clothing and respiratory protection), informing workers of hazards, work practices (emergency procedures, control of airborne chlorine, storage, handling, requirements for work areas, waste disposal, confined spaces and enclosed spaces), sanitation practices and monitoring and recordkeeping requirements.
