Explosion-proof illumination for hazardous areas – Zone 0 & Zone 1
Peli Lighting designs and manufactures ATEX-certified, intrinsically safe torches, head torches and portable lights for explosive atmospheres. From compact inspection lights to hands-free headlamps, Peli products deliver reliable performance for oil & gas, petrochemical, offshore, utilities and emergency response applications.
An intrinsically safe torch is a portable lighting device designed so it cannot release enough electrical or thermal energy to ignite explosive gases, vapours, or dust. This makes it safe for use in hazardous areas where there is a high risk of explosion.
Unlike standard torches, intrinsically safe models are tested to strict international standards such as ATEX (European Union directive for explosive atmospheres) and IECEx (global certification scheme).
Peli intrinsically safe torches are rigorously tested and certified to meet ATEX safety standards, ensuring they can be used in hazardous areas where flammable gases, vapours, or dust may be present.
Zones denote the areas in which a torch is safe to operate:
Zone 0 torches are safe to use in environments where an explosive atmosphere of gas, vapour, or mist is continuously present, such as inside a subterranean petrol tank.
Zone 1 torches are designed for areas where an explosive gas atmosphere is likely to occur during normal operation, such as around a petrol pump.
These classifications help ensure workers choose the right lighting for the level of risk in their working environment.

What is static earthing? Static grounding or earthing systems remove charged static electricity between the earth and an object. This is a requirement for facilities operating within hazardous areas, protecting personnel and plant assets from explosions or fires.
Static electricity is part of everyday life and is generated when materials come in to contact with each other and then separate i.e. electrostatic charging occurs at the interface.
Static electricity can pose several dangers in industrial settings, particularly in environments where flammable or combustible materials are present. Some of the dangers of static electricity include:
Uncontrolled electrostatic discharge can be prevented by the specification and installation of certified static earthing and bonding systems such as StuvEx Safe-Ground range.
The team visited the StuvEx HQ in Belgium to undertake advanced Technical Product Training. During the training they had front row seats to a live demo. The below video shows the result of an explosion caused by static.
The fuel for this explosion you ask? 1 Teaspoon of sugar! Knowledge on risks associated with dust atmospheres is poor in comparison to gas atmospheres. Couple that with a poor understanding of risks associated with static electricity and you have a recipe for disaster.
Now we can examine earthing, grounding, and bonding in more detail. All are important techniques used to control static electricity and prevent hazards such as electric shocks, fires, and explosions.
Earthing involves connecting an object to the earth with a conductive wire or rod. This allows any static electric charge on the object to safely dissipate into the ground, reducing the risk of a static electric discharge.
Grounding is the process of connecting electrical equipment or conductors to the earth or a grounding electrode in order to prevent the buildup of static charge. This helps to dissipate any excess energy and reduce the risk of a static spark occurring.
Bonding is the process of connecting two or more conductive objects together in order to equalise the potential between them, preventing the buildup of static electricity. This ensures that any static charge is evenly distributed and does not pose a danger to workers or equipment.
| Earthing | Grounding |
|---|---|
| Is used as safety against electric shock | Mainly used for the safety of appliances (malfunctions of devices) |
| Used when there is a need for electric discharge | Used when there is electric imbalance due to overloading in the system |
| Placed between the device and earth | Placed between neutral of device and ground |
| Used in homes, motors, and generators | Used in power transformers and neutral motors |
By implementing proper grounding and bonding procedures, businesses can effectively reduce the risk of static electricity causing a spark and potentially igniting flammable gases, vapours, or combustible dusts in the workplace. This not only protects the safety of employees and equipment but also helps to comply with various safety regulations and standards.
investing in proper earthing, grounding, and bonding measures is crucial for businesses operating in hazardous environments to maintain a safe and productive work environment. It is important to regularly inspect and maintain these systems to ensure their effectiveness and prevent any potential hazards from occurring.
Together with StuvEx, Thorne & Derrick can offer a variety of Earthing & Grounding products to assist with static ground monitoring and control in hazardous area locations.
