Safety requirements for the use of equipment, including UV/IR torches, in hazardous areas such as Zone 1 and Zone 2 are subject to regional and international standards. These standards regulate what type of equipment can be used in each zone based on the risk level.
Zone 1 is defined as an area where an explosive gas atmosphere is likely to occur occasionally in normal operation. Zone 2, on the other hand, is an area where an explosive gas atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
UV/IR torch
A UV/IR torch (or any equipment) that can be used in these areas would need to be specifically designed, tested, and certified for use in explosive atmospheres. The equipment should meet the specific standards outlined for explosive atmospheres, like the ATEX directive in the EU or the equivalent standards in other regions.
For example, for an electronic device to be used in Zone 1 or Zone 2, it would typically need to be “intrinsically safe” - meaning that any sparks or heat that it might produce would not be sufficient to cause ignition of the specific hazardous substances present in the atmosphere.
So, a UV/IR torch can be used in Zone 1 and Zone 2 areas, but it must be certified as safe for use in such environments. You should always refer to the manufacturer’s specifications and certifications, and when in doubt, consult with a safety expert or engineer.
