What is the primary stipulation regarding gas/vapor tight continuous corrugated metallic sheathed cables in restricted public access areas?

The primary stipulation regarding gas/vapor tight continuous corrugated metallic sheathed cables in restricted public access areas is that only qualified persons should service the installation. This requirement is crucial because gas/vapor tight cables are designed to prevent the ingress of potentially hazardous gases and vapors, which poses a safety risk if not handled properly. Qualified personnel have the necessary training and knowledge to ensure that any installation, maintenance, or servicing of these cables is conducted safely and effectively, minimizing the risk of accidents or equipment failures.

Having restrictions on who can service these installations is key to maintaining safety in environments where explosive gases or flammable vapors may be present. Qualified personnel are trained to understand the specific hazards related to these conditions and know how to properly manage and mitigate risks associated with the handling of such cables. This helps to ensure compliance with safety codes and standards, protects equipment integrity, and ultimately safeguards personnel and nearby populations.
