OSHA has cited Tampa Electric Co. and Critical Intervention Services, a security services provider, for $43,458 in total proposed penalties, following a release of anhydrous ammonia – a chemical refrigerant – at its Gibsonton facility.
OSHA responded to the incident on May 23, 2017 and determined that the ammonia release occurred when a relief valve activated after a pipeline became over pressurized. As a result, four workers were taken to the hospital for observation and released.
