ATEX Zone Guide

Intrinsically Safe ATEX Zones

Three components are necessary to create an explosion;

1. Flammable material – A gas, vapor, or mist.

2. Oxygen – Oxygen,- regular breathable air, is sufficient.

3. Ignition Source – Extreme heat or a spark.

 In a flammable atmosphere environment, special precautions must be taken to prevent catastrophic explosions. All portable lighting must be specifically engineered to avoid a spark from occurring and igniting any flammable vapors or explosive mists. In some cases, these vapors and mists can be colorless and odorless, making them especially dangerous.

 Commercial worksites have different hazardous areas classified at a specific level called a "Zone." All equipment safety ratings must be carefully selected based on the most dangerous Zone it may encounter; therefore, it is critical to identify the Zone in which you will be working. Let's take a look at the specific characteristics of each Zone.

 Zone 0

An area in which an explosive atmosphere is always present. 

 Zone 1

An area in which explosive atmospheres are likely to occur during regular operation. This may be due to leakage, scheduled maintenance, or emergency repairs.

 Zone 2

An area in which an explosive atmosphere does not occur during normal operation, or for a short period of time only. This is usually the result of an accident or other unusual operating conditions.

 The Nightstick XPP-5422G is the definition of an intrinsically safe product. This ATEX safety certified Dual-Light? Flashlight light is not capable of releasing enough electrical or thermal energy under normal or abnormal circumstances to cause ignition, even in a Zone 0 environment. The light is rated IP-67 water/dustproof and puts out 240 lumens with an impressive beam distance of 170 meters. Additionally, the torch includes both a flashlight and downward floodlight, which can be turned on separately or simultaneously.
