In response to a request from the Anchorage, Alaska Health Department, an evaluation was made of health effects among emergency responders exposed to a CFC-22 (75456) release at the ice skating rink (SIC-7999) in the Dimond Center shopping mall. The 24 year old assistant manager of the rink died of asphyxiation while trying to stop a refrigerant leak inside a compressor room. Two other workers lost consciousness and were resuscitated. Two members of an adjoining health club were overcome while swimming in the pool. Possible health effects were investigated in 106 individuals who were in the building during the incident. Emergency responders and other individuals who were in the mall reported symptoms, including lightheadedness, dizziness, eye/nose/throat irritation, headache, giddiness, and weakness. The author concludes that a fatal hazard existed at the Dimond Ice Chalet at the time of the incident. The author recommends measures for employers who operate CFC type refrigeration systems, including a periodic maintenance program, a hazard communication program, the posting of confined spaces, engineering controls, a comprehensive respirator program, and a comprehensive emergency action plan.
