As previous indicated in System Layout, hazards within and around a LPG facility need to be assessed. Consideration of emergency-response resources, fire protection requirements and other factors at a site may dictate basic construction features (e.g., mounded storage.) Ultimately, public-safety agencies, insurance carriers, the LPG system designer and the owner must define appropriate safety systems. See also, Security, Training & Documentation and Standards.

Emergency Shutdown System

Minimizing the potential volume and duration of accidental LPG release is an important safety area. Beyond the protection against a system breech provided by excess flow valves, Total Product Control Systems and comprehensive Emergency ShutDown systems have evolved over time to offer superior containment capabilities.
TPCS/ESD applications normally include actuated valves to isolate all tank openings, fuel transfer connections and other selected piping and process equipment. Remote and automatic closure of these valves can quickly seal the system. Interlocks to main system control, site power supply, off-site alarms, etc. can yield controlled, safe shutdown and improved emergency response.
