Portable hazardous-location lighting brings a movable source to inspection, maintenance and temporary work positions. It includes several formats, each with its own electrical arrangement and exact approval.
Different formats serve different tasks
Hand lamps reach beside valves and behind equipment. Supported lights leave hands free at one repair position. String assemblies place several heads along a run, while personal flashlights and headlamps move with the wearer. A format describes handling and beam placement, not a classification.
Explosionproof is a protection technique
An approved explosionproof design manages an internal ignition without igniting the specified surrounding atmosphere. Intrinsic safety and dust-protection techniques work differently. Read the actual class or Zone, group, temperature marking, ambient range and certificate conditions for the offered product.
Check the whole supply arrangement
Direct-powered and transformer-fed lamps can look similar while using different input and lamp-side voltages. Confirm AC/DC, transformer inclusion, cable length and connections. Low voltage alone is not intrinsic safety, and wet/conductive work can have specific electrical requirements.
Plan handling and inspection
Use permitted supports, keep cables away from damage and maintain a clear retrieval route. Inspect complete assemblies and replace components only as allowed by their documentation. Temporary use does not waive classified-area requirements.
Browse portable lighting by type, then use the exact model documentation to confirm the configuration for the job.
