Hazards from dusts and spilled product fall into two distinct categories; the first is dusts that are hazardous to health. This category includes obvious products like asbestos and silica dust, but any dust that can be breathed in by the operator or other personnel in the workplace is likely to be hazardous to health to a degree. Industrial Vacuum Cleaners with M-Class and H-Class filtration ensures hazardous dusts are appropriately handled when being recovered.

The second category is dusts that are hazardous in the environment. The obvious category is dusts that can potentially cause an explosive atmosphere, particularly organic products like sugar and flour. Some products fall in to both categories such as wood dusts, which are both hazardous to health and potentially explosive. ATEX rated Industrial Vacuum Cleaners must be specified for use in ATEX zones.

Selecting an appropriate Industrial Vacuum Cleaner requires careful consideration of the potential hazards which then informs the specification of the machine. BVC – British Vacuum Cleaners is the leading brand of British manufactured industrial vacuum cleaners. Manufactured by Quirepace in Fareham, Hampshire the range includes both M-Class and H-Class machines for dusts hazardous to health and ATEX rated equipment suitable to operate in potentially explosive atmospheres.

Selecting Ex Concepts of Protection

The Explosive Atmospheres market is both lucrative and expanding, but certification requirements—and the level of scrutiny by both buyers and regulatory authorities—are increasing. To access this market, it is imperative that equipment manufacturers understand the specific design, manufacturing, and certification requirements for their products.

When a ‘Zone’ has been established, special precautions must be taken by the manufacturer to reduce the likelihood of ignition to an acceptable level—and, where necessary, use mitigation measures to reduce the consequences of an explosion. These special methods are typically achieved by applying defined EX concepts from published standards and usually require specially designed products. The ‘a’, ‘b’, and ‘c’ designations after the protection concept indicate the level of protection:

a = Zone 0/20

b = Zone 1/21

c = Zone 2/22

Selecting the correct concept (or often, a combination of concepts) is critical before any design or development takes place.

Examples of Commonly Recognised Ex Concepts of Protection

FLAMEPROOF: Ex da, db or dc

A method of protection where the equipment is contained within an enclosure capable of withstanding an internal explosion of a flammable gas or vapour without damage, and without transmitting the internal flame to the external explosive atmosphere through any joints or structural openings.

INTRINSIC SAFETY: Ex ia, ib or ic

A protection technique based on limiting the electrical energy within the apparatus and interconnecting wiring exposed to an explosive atmosphere to a level below that which can cause ignition—either by sparking or heating effects.

PRESSURISATION: Ex pxb, pyb or pzc

A method of protection using pressurised protective gas to prevent the ingress of an explosive atmosphere into a space that may contain an ignition source. If necessary, it includes continuous dilution of any atmosphere within that space that might contain an emission source.

INCREASED SAFETY: Ex eb or ec

A method of protection in which additional measures are applied to electrical apparatus to provide increased security against excessive temperatures, arcs, and sparks during operation.

LIQUID IMMERSION: Ex ob or oc

A method of protection where electrical apparatus is made safe by oil immersion, preventing ignition of an explosive atmosphere either above the oil or outside the enclosure. The oil acts as a barrier between the explosive atmosphere and the electrical components.

POWDER FILLING: Ex qb or qc

A method of protection where the enclosure is filled with granular material, so that if an arc occurs, it is unlikely to ignite the external explosive atmosphere.

ENCAPSULATION: Ex ma, mb or mc

A method of protection in which components that could cause ignition by sparking or heating are enclosed in a compound, preventing any contact with the explosive atmosphere.

NON-INCENDIVE: Ex nC or nR

A type of protection applied to electrical apparatus such that, under normal operation, it cannot ignite a surrounding explosive atmosphere—and any fault capable of causing ignition is unlikely to occur.

In addition to these commonly used electrical concepts, there are also protection methods for:

• Non-electrical equipment (Ex h)
• Optical equipment (Ex op is, op sh, and op pr)
• Dust-only atmospheres (Ex ta, tb, and tc)

Where no standard concept is suitable (which is very rare), special protection may be used (Ex sa, sb, and sc). However, this is a complex and challenging process.

Sean Clarke CEng MSc FIET is the General Manager of ExVeritas are a UK Government Appointed Body for UKCA ‘Ex’, an ATEX Notified Body and an IECEx Certification Body and Test Laboratory, ExVeritas offers design reviews to help determine which protection concepts are feasible for your equipment and training courses for equipment designers. www.exveritas.com for more information.

Demand for PFAS testing at TÜV Rheinland has increased globally by more than 30 percent / Chemical restrictions require a great deal of development and testing effort from manufacturers and distributors / TÜV Rheinland offers companies precise product analysis and support in implementing legal requirements / www.tuv.com/pfas

TÜV Rheinland is expanding its testing capacity worldwide to meet the growing global demand for testing services for per- and polyfluoroalkyl substances (PFAS). The testing services provider has seen demand increase by more than 30 per cent year-on-year. PFAS, a group of more than 10,000 known substances, are used in many industries for their functional properties, including textiles, food packaging, furniture and carpet fabrics, as well as mechanical and automotive engineering. However, their potential risk to the environment and human health is increasingly the focus of regulatory and public attention.

The chemical ban on PFAS in many countries in the world poses new challenges for manufacturers and retailers and requires a lot of development and testing. Companies that manufacture, trade or import products will need to monitor and reduce PFAS. TÜV Rheinland is helping companies prepare for changes in legislation by providing accurate chemical analysis. "This enables companies to adapt to changes in the legal situation at an early stage, establish responsible action as a quality feature and thus remain competitive," explains Steffen Tümptner, an expert at TÜV Rheinland.

PFAS in industry – further restrictions on the horizon

In the EU, several classes of PFAS are already subject to restrictions, for example under the REACH and POP regulations. In September 2024, EU Regulation 2024/2462 was adopted, which will phase in bans on PFHxA (C6 PFAS) in certain applications over a five-year period. This includes a ban on PFAS in clothing, footwear, paper and board in contact with food and in cosmetics from October 2026. From October 2027, the ban will be extended to other textiles and leather products. European authorities are currently considering further restrictions that could cover more and more PFAS in the long term. The US authorities are also taking far-reaching action to restrict PFAS at the national level. In April 2024, the

US Environmental Protection Agency (EPA) issued nationwide limits for six groups of substances in tap water, making them among the strictest in the world.

Accurate analysis and expert advice from TÜV Rheinland

TÜV Rheinland's testing packages, training and on-site audits provide the tools needed to analyse products, find suitable alternatives and ensure more sustainable production. More information on PFAS for interested parties and companies is available at: www.tuv.com/pfas

In avoiding costly breakdowns, Condition Based Maintenance (CBM) is proven to be far superior to Planned Periodic Maintenance (PPM). Not only is PPM needlessly costly, due to the time wasted stripping down perfectly functioning machinery, it can sometimes make matters worse by introducing faults during the process of stripping down and rebuilding the machine. Even more of a problem is deciding the correct PPM time intervals. Too short an interval, means more wasted time and cost (and more potential for introducing faults) but too long means more unexpected breakdowns.

CBM makes use of tools such as vibration and temperature analysis to run an efficient and effective maintenance program able to predict faults BEFORE they occur. This is where the major cost benefit of CBM lies. Repairing faults AFTER a breakdown can be VERY costly, particularly where there has been collateral damage and/or injury to personnel. This is even more the case in hazardous locations where a complete shutdown of operations may also be required to effect repairs.

However, for use in hazardous locations, CBM instruments are required by law to be intrinsically safe and unable to ignite explosive atmospheres (ATEX). This means that vibration and temperature analysers must be CERTIFIED for use in the hazardous location. But the certification rules are different in different parts of the world AND in different “Zones” where explosive atmospheres are likely to exist. For example, a tanker vessel could visit many different oil and gas terminals in different countries, or a maintenance team might find themselves working unexpectedly at a wastewater treatment plant with the potential for methane build-up. So, how do you know you have the correct certification for your tools in all the different locations?

The simplest solution is to cover all eventualities by using instruments certified for Zone 0 (hazard exists continuously). Normally, that would make them much more expensive but fortunately, Test Products International (TPI) has achieved a significant cost breakthrough with the very affordable TPI 9085Ex vibration analyser. With built-in on-meter diagnostics and the all-important ability to TREND readings over time, the “go anywhere” TPI 9085Ex has WORLDWIDE Zone 0 certification, meaning it can be used in ANY hazardous atmosphere and in ANY location.

The 9085Ex detects unbalance, misalignment and looseness in rotating equipment. It also measures “bearing noise” and displays it in bearing damage units (BDU) roughly equivalent to “percentage bearing wear”. In addition, the 9085Ex uniquely incorporates a directly contacting temperature sensor within its vibration probe. This gives a highly accurate, virtually instantaneous, surface temperature reading for the bearing, simultaneously as the vibration reading is taken. With a high BDU reading and high temperature, you know that what you are seeing really is a worn bearing.

The compact handheld TPI 9085Ex is extremely affordable and simple to use and an invaluable part of every maintenance tool kit. It can be used standalone for fault diagnosis or by using the FREE TPI Bridge App, “routes” and readings can be transferred to and from the 9085Ex anywhere in the world using mobile devices (e.g. smart phone or tablet PC) and then via Bluetooth to and from the 9085Ex. “Routes” are simply lists of machines showing exactly what readings need to be taken and where to take them. The readings are then automatically time and date stamped by the 9085Ex and saved back into the route for automatic transfer to computer-based trending software.

In industrial settings, safety is paramount, especially in environments where flammable or toxic gases are present. A robust gas detection system is an important line of defense, but it’s not the whole story. Integrating flame detection into your safety setup can create a safer and more reliable environment.
 

The Role of Gas and Flame Detection Systems

Gas detection systems are designed to identify harmful gases in the air, whether combustible, toxic, or asphyxiating. They provide early warnings, helping to enable preventive action before conditions become dangerous. However, gas detection alone doesn’t account for what happens when a gas leak ignites.

Flame detection systems complement gas detectors by identifying the presence of fire, which may occur even where gas concentration hasn’t yet reached detectable levels. Together, these systems can contribute to a more comprehensive safety net that addresses both potential and actual hazards.
 

Seven Reasons to Include Flame Detection in Gas Detection Systems 

1. More Comprehensive Hazard Mitigation

Gas detectors and flame detectors work hand-in-hand to prevent accidents and mitigate risks. While gas detectors alert you to the presence of a leak, flame detectors respond to fires that could result from undetected or ignited gases. 

2. Faster Response to Fire Emergencies

A gas leak can ignite in seconds, turning a potential hazard into an active emergency. Flame detectors react in real-time to the presence of a flame, helping to enable prompt action to contain the fire and prevent escalation. 

3. Helps Eliminate Blind Spots

Gas detection systems can only monitor specific zones. In scenarios where a leak occurs outside the detection range or a minor leak ignites directly, flame detectors can be an important second layer of protection. 

4. Tailored for High-risk Industries

In industries like oil and gas, petrochemicals, and manufacturing, the risk of fire due to flammable gases is ever present. Flame detection helps protect these high-stakes environments against both minor and catastrophic ignition events. 

5. Meeting Regulatory Standards

Safety regulations often require both gas and flame detection systems for compliance. Adhering to these standards not only protects your team and assets but also ensures your operations meet legal and industry benchmarks. 

6. Minimizing Damage and Downtime

Early flame detection can activate suppression systems, limit the spread of fire, and enhance the safety of personnel. By containing incidents quickly, businesses can avoid costly equipment damage and extended downtime. 

7. Enhanced Operational Safety and Continuity

Combining gas and flame detection creates a more resilient safety framework that reduces the likelihood of accidents and enables a quicker recovery in the event of an incident. This reliability is key to maintaining trust and productivity.
 

Despite its importance, users might hesitate to include flame detection in their safety systems due to perceived challenges such as cost, complexity, or maintenance. Users may also assume that gas detection alone is sufficient for preventing incidents, underestimating the speed at which a leak can escalate into a fire. Addressing these misconceptions and highlighting the critical role of flame detection in mitigating catastrophic events is key to overcoming reluctance and ensuring comprehensive safety solutions.

The Bottom Line: A Layered Defense is Key

Safety in industrial environments is not about choosing between gas or flame detection—it’s about understanding the benefits of both to build a layered defense. While gas detectors prevent potential hazards by identifying leaks, flame detectors act as a safeguard when ignition occurs.

Safety managers may consider this combination a necessity in today’s high risk, high stakes industries. By integrating flame detection into your gas detection system, you help to ensure that your operations are protected from the full spectrum of potential hazards, safeguarding lives, assets, and your reputation.
