Control Labeling - Emergency Shutdown

What is the requirement for mapping utility systems and identifying controls for utility system shutdown?

Any examples are for illustrative purposes only. 

Utility system maps are important tools to be used when trouble-shooting a system problem and to isolate portions of the system when needed. Maps may be drawings, diagrams, tables, or other effective means that identify the location where a control device or equipment resides.  When mapping a utility system, label components in accordance with their actual labeling in the field so they may be easily identified. 

These maps often consist of construction as-built drawings, but many facilities have been altered in phases after the original construction, therefore it is important to have accurate, up to date information that includes how the various generations of these systems interconnect. 

System equipment that is to be identified may include but is not limited to: 
  • Heating Ventilating and Air Conditioning Systems
  • Plumbing Systems
    • Fire Protection Systems
    • Med gas systems
  • Electrical Systems
    • Fire alarm systems
    • Lighting
