The International Electrotechnical Commission has published a new Technical Specification called IEC 60079-32-1: “Explosive atmospheres - Part 32-1: Electrostatic hazards - Guidance”. This Technical Specification is a guidance document which is the latest addition to the IEC series of 60079 “Explosive Atmospheres” standards that are designed to limit fires and explosions caused by electrical malfunctions within hazardous locations.

Static control for hazardous areas
For over 30 years, Newson Gale has been leading the way in hazardous area static grounding control, serving industries where processes generating static electricity have the potential to ignite flammable or combustible atmospheres.
In many branches of industry, hazardous (explosive) atmospheres exist due to the presence of flammable liquid vapors, gases, dusts and fibers. No matter how the explosive atmosphere is classified, it is vital that all potential ignition sources are eliminated, and Static Electricity is perhaps the most insidious of them all. Static Electricity is generated in industry by virtually all operations and processes involving movement - for example product transfer, mixing and size reduction. Fires and explosions can occur owing to uncontrolled static discharge from plant, people and materials, and these commonly result in civilian injuries and fatalities, as well as significant financial losses in direct property damage and plant downtime.
To help control these risks, Newson Gale offers a wide range of static grounding and bonding equipment which is purpose made to provide optimum safety in explosive atmospheres and other hazardous operating environments. The Newson Gale® range prevents static charge accumulation by using practical and innovative design, and ensures effective static control on three levels: -
- Earth-Rite® series of static ground indicators and interlock systems
- Bond-Rite® series of self testing static grounding clamp units
- Cen-Stat™ series of static grounding and bonding clamps, cables, reels and test instruments
Newson Gale has a wealth of experience gained in controlling static electricity in explosive atmospheres.
The Earth-Rite Mobile Ground Verification system (MGV) is a unique, patented technology designed to provide automatic confirmation of a positive electrostatic ground connection for vehicles collecting and transferring combustible products.
The Earth-Rite RTR is the most advanced Tank Truck Grounding (Earthing) System for protecting personnel and plant assets from static hazards during tanker truck loading and offloading operations.
The OhmGuard® hose continuity tester is designed to test hoses used on vacuum trucks and tanker trucks prior to the transfer of flammable or combustible products. It verifies that the electrical conductivity of the hose is functioning correctly, ensuring static electricity is not permitted to accumulate on the metal components of the hose which will eliminate the risk of a fire or explosion caused by the discharge of a static spark.
The Bond-Rite Grounding CLAMP, patented exclusively by Newson Gale, is the only static grounding clamp that provides operators with visual verification that potentially charged equipment is connected to a verified static grounding point.
The innovative design of the Bond-Rite REMOTE provides enhanced safety and security by continuously testing the connection of the clamp to the container or other conductive item of plant in a complete loop made through the designated grounding point.

New innovation lowers the total cost of ownership for customers that require active static grounding protection
Newson Gale’s Earth-Rite MULTIPOINT II is the new innovation which will provide customers with a unique value proposition that makes the active static grounding of multiple items of equipment with interlock control more cost effective than other options available to the EX/HAZLOC industries.
Businesses with HAZLOC atmospheres are exposed to the risk of static electricity igniting flammable gas, vapor and dust atmospheres. This ignition risk can be eliminated by ensuring equipment is bonded and grounded in accordance with NFPA 77 “Recommended Practice on Static Electricity”. The new PIRANHA grounding clamp, by Newson Gale Inc., is designed to eliminate such fire and explosion risks.
Newson Gale has launched its next generation static grounding relay, the Earth-Rite OMEGA II. Featuring a HAZLOC approved Intrinsically Safe certified circuit for use in the highest gas, vapor and dust groups the Earth-Rite OMEGA II monitors the resistance of circuits designed to ground equipment that are subjected to electrostatic charging.
The newly upgraded intrinsically safe Earth-Rite TELLUS II from Newson Gale Inc. offers effective, constantly verified static ground monitoring for drums, IBCs and other mobile or portable equipment during hazardous area operations. When in use the TELLUS II provides the operator with a bright green flashing LED to confirm a positive connection to ground, and also provides a pair of output contacts for interlock with pumps, valves or other control or alarm devices.
PTFE-lined steel pipelines carrying flammable liquids are protected from static electricity build-up and discharge by an economical grounding paddle. Due to the large effective capacitance of the PTFE or similar plastic lining against a steel housing, large charges can build up in an active pipeline over a period of several hours, even days.
