Your company has recently hired an experienced HS auditor to help identify gaps in your HS program. One of the issues that the consultant discovered was that a large quantity of ammonia (NH3) is stored at your facility as a part of the refrigeration system. The consultant also discovered that two very ancient Scott self contained breathing apparatus (SCBA) units were stored in the Maintenance Department for use if ammonia leaks develop in the system. The consultant could not determine if your company had a written respiratory program. Maintenance technicians stated that they knew how to use the Scott units but could not remember the last time any formal training had taken place regarding the respirators or responding to ammonia leaks. In addition, no inspection or maintenance records were available for the SCBA units
