What is the CAL-OSHA Occupational Exposure Limit for anhydrous ammonia in parts per million (ppm)?

• A. 50 ppm
• B. 25 ppm
• C. 35 ppm
• D. 100 ppm

Answer: (B)

The CAL-OSHA Occupational Exposure Limit for anhydrous ammonia is established to protect workers from the harmful effects of exposure to this compound. The correct value is 25 parts per million (ppm), which signifies the maximum concentration of anhydrous ammonia in the air that workers can be exposed to during an 8-hour work shift. This limit is based on health studies that assess the effects of ammonia on human health, aiming to minimize the risk of respiratory irritation and other adverse health consequences. Other options present higher exposure limits, which could lead to increased health risks for workers. Setting the limit at 25 ppm is a precautionary measure aligned with safety standards to ensure that workers maintain a safe working environment while handling ammonia, helping to prevent incidents related to acute and chronic exposure. Understanding these exposure limits is vital for industrial refrigeration operators and safety managers in ensuring compliance with regulations and promoting workplace safety.
