The British Safety Industry Federation (BSIF), through its Respiratory Protection Group, has relaunched the ‘Clean Air? Take Care!’ campaign, supported by a comprehensive range of online guidance resources designed to help employers and wearers understand and address the key considerations of respiratory protection in the workplace.

The accompanying campaign concertina leaflet has been developed to reinforce essential respiratory health and safety messages across UK workplaces. Designed for both employers and respiratory protective equipment (RPE) wearers, it provides a concise and accessible reminder of the principles that support effective respiratory protection.

Developed as a practical awareness resource for employers, health and safety professionals, supervisors and workers, the leaflet presents key information in a simple, accessible format while providing direct access to more detailed guidance through QR codes on every page.

The refreshed publication aims to support organisations in tackling one of the UK's most significant occupational health challenges. Despite increased awareness of workplace health risks, work-related respiratory disease remains a major cause of ill health and death, with thousands of workers affected every year.

The campaign  highlights a range of key topics, including:

•           Recognising invisible airborne hazards

•           Controlling exposure at source through ventilation and extraction

•           Understanding legal responsibilities

•           Selecting appropriate respiratory protective equipment (RPE)

•           The importance of face fit testing

•           Training users in correct wear and use

•           Maintaining equipment effectively

•           Purchasing products from trusted suppliers

Each section is supported by a dedicated QR code, enabling readers to access further information, guidance and practical resources relevant to the topic being discussed. This approach allows the leaflet to communicate the key messages clearly and concisely while providing a pathway to more in-depth learning.

Commenting on the launch, BSIF CEO, John Hooker said:"We are proud to relaunch the ‘Clean Air? Take Care!’ campaign with updated emphasis on the entire area of Respiratory Protection making the key messages clearer and more accessible than ever. Work-related respiratory disease remains a major source of occupational ill health, and we must continue to work together to keep the risks and the controls firmly front of mind.

"A common misconception is that respiratory protection is simply a matter of handing someone a mask. Effective protection depends on much more, including selecting the right product for the hazard, ensuring it fits the wearer correctly through face fit testing, providing appropriate training, and maintaining equipment throughout its life. Just as importantly, organisations should ensure they purchase products from trusted suppliers, as substandard or unsuitable products can leave workers exposed to significant risks."

The refreshed ‘Clean Air? Take Care!’  campaign forms part of the BSIF Respiratory Protection Group's ongoing commitment to raising awareness of respiratory hazards and promoting best practice in the selection, use and maintenance of respiratory protective equipment.

For manufacturers, compliance with the latest IECEx procedures helps ensure certification remains recognised throughout global markets.

Certification bodies also benefit from clearer procedures that improve consistency when assessing products against the IEC 60079 standards.

Ultimately, end users gain increased confidence that certified equipment has been assessed using harmonised international processes.

Growing Demand from Emerging Industries

One of the biggest drivers behind continued IECEx development is the rapid growth of emerging technologies.

Hydrogen infrastructure, battery energy storage systems, carbon capture facilities and renewable energy projects all present new hazardous area challenges.

As these industries expand, manufacturers increasingly require certification that is recognised internationally rather than being limited to one geographical region.

IECEx continues to play a central role in supporting these developments.

The Importance of the IEC 60079 Series

The IECEx Scheme is built around the internationally recognised IEC 60079 series of standards.

These standards cover every aspect of explosion protection, including:

• General equipment requirements
• Flameproof enclosures (Ex d)
• Increased safety (Ex e)
• Intrinsic Safety (Ex i)
• Pressurised equipment (Ex p)
• Equipment installation
• Inspection and maintenance
• Hazardous area classification

As these standards evolve, the IECEx Scheme is updated to ensure certification processes remain aligned with current technical requirements.

What Should Manufacturers Do?

Companies manufacturing equipment for explosive atmospheres should review the latest IECEx documentation and ensure internal certification processes remain aligned with current requirements.

Although existing certificates remain valid where appropriate, organisations planning new product approvals should work closely with their certification body to understand any procedural changes introduced through Edition 9.0.

Maintaining awareness of evolving IEC standards will also help reduce delays during future certification projects.

Looking Ahead

International demand for explosion-protected equipment continues to increase, particularly within hydrogen, renewable energy and advanced manufacturing sectors.

The publication of IECEx 02 Edition 9.0 reinforces the scheme's position as one of the world's leading certification systems for equipment used in explosive atmospheres.

As hydrogen technologies continue to grow, so does the need for pressure measurement equipment that can operate safely and reliably in demanding hydrogen environments. From production and storage to transportation and refuelling, hydrogen systems often involve high pressures and challenging operating conditions.

The HP1000H from ESI Technology has been specifically developed to meet these requirements. Based on the proven HP1000 platform, the HP1000H combines high-pressure capability, hydrogen-compatible materials, and robust sensor technology to provide accurate and dependable pressure measurement across the hydrogen value chain.

Designed for pressures up to 5,000 bar (72,500 psi), the HP1000H offers engineers a trusted solution for critical hydrogen applications.

Engineered for Hydrogen Service

Hydrogen presents unique challenges for pressure measurement equipment. Its small molecular size can affect materials differently from many other gases, making material selection a critical part of transmitter design.

To address these challenges, ESI developed the HP1000H using hydrogen-compatible titanium wetted parts. Each unit undergoes testing in accordance with ISO 11114 standards, which assess the suitability of metallic materials for hydrogen service.

ESI also supplies hydrogen-approved versions with certification confirming their compatibility with hydrogen applications. This gives engineers confidence that the transmitter has been specifically designed and tested for use within hydrogen systems.

In many of these applications, pressure measurement is critical for process control, equipment protection, and regulatory compliance.

Built for Extreme Pressures

Hydrogen systems frequently operate at very high pressures, particularly in storage and refuelling applications. As a result, pressure transmitters must be able to withstand demanding operating conditions while maintaining measurement accuracy.

The HP1000H uses a unique one-piece titanium sensing assembly. Unlike conventional pressure transmitters that rely on welded components, the diaphragm and pressure housing are machined from a single piece of titanium alloy.

This design removes welds from the pressure boundary, improving structural integrity and reducing potential points of failure. It also provides excellent resistance to pressure spikes, fatigue, and cyclic loading.

Combined with the natural corrosion resistance of titanium, this robust construction helps ensure long-term reliability in demanding hydrogen environments.

Proven Silicon-on-Sapphire Sensor Technology

At the heart of the HP1000H is ESI Technology's Silicon-on-Sapphire (SOS) sensor technology.

SOS technology offers exceptional long-term stability, excellent accuracy, and reliable performance across wide temperature ranges. These characteristics are particularly important in hydrogen applications, where operating conditions can vary significantly.

The sapphire substrate provides outstanding electrical insulation and contributes to the sensor's durability and measurement stability over time.

As a result, the HP1000H delivers dependable pressure measurement with minimal drift, helping to reduce maintenance requirements and improve long-term system performance.

ATEX Certification for Hazardous Areas

Many hydrogen applications operate in potentially explosive atmospheres, making hazardous area certification an important consideration.

To support these environments, the HP1000H is available with ATEX Intrinsically Safe approval on 4-20 mA versions. This certification enables installation within designated hazardous areas when used as part of an approved intrinsically safe system.

By combining hydrogen compatibility with hazardous area certification, the HP1000H provides a practical solution for applications where both safety and performance are critical.

A Pressure Transmitter Designed for the Future of Hydrogen

The transition towards cleaner energy continues to drive investment in hydrogen technologies. As systems become more advanced and operating pressures increase, dependable pressure measurement becomes increasingly important.

The HP1000H combines hydrogen-compatible materials, high-pressure capability up to 5,000 bar, proven Silicon-on-Sapphire technology, and optional ATEX certification in a single robust transmitter.

Whether monitoring hydrogen production, storage, transportation, or refuelling systems, the HP1000H delivers the accuracy, durability, and reliability engineers need to support the next generation of hydrogen infrastructure.

Dust is one of the most common hazards across manufacturing and chemical processing sites, yet it remains one of the most underestimated. Long-term exposure is linked to occupational asthma, COPD and other irreversible lung conditions, while numerous dusts also carry a combustible risk if allowed to accumulate. Because symptoms of dust-related illness are rarely immediate, the consequences of inadequate control are often only seen years later, making prevention far more valuable than any later remedy.

Effective dust control depends on understanding where dust is generated, not just how it is filtered afterwards. A facility audit, ideally carried out by qualified personnel, can determine average and peak airborne concentrations at key points across a site. This is typically when previously unmonitored dust sources are identified, such as transfer points, mixing operations or material handling areas where extraction either doesn't exist or is poorly positioned relative to the source.

Local exhaust ventilation (LEV) is one of the most effective controls available, but only when correctly designed and located close to the point of dust generation. Hoods positioned too far from the source, or sized incorrectly for the airflow required, or poorly designed are often the main factors where inadequate dust extraction exists. Reviewing existing hood placement against actual dust-generation points is one of the simplest ways to identify gaps in an otherwise established system.

Once exposure points have been addressed, attention should turn to the dust collection technology itself. A dust collector needs to deliver consistent, predictable performance, removing contaminants effectively while maintaining stable airflow. Filter unit type and media selection are central to this. Each application has its own challenges and more efficient choices, with many factors considered when choosing the correct equipment. Dust load, particle size, bulk density, dust properties, operating processes, and many more considerations should be taken into account when designing an effective LEV system.

A competent dust extraction and filtration engineer can specify a system matched to actual dust loads, effective airflows throughout the system, and compliance requirements rather than over- or under-specifying equipment based on assumptions.

The benefits of getting this right extend well beyond compliance. Effective dust control reduces airborne contamination risk during production, supports consistent product quality, and limits downtime caused by system failure or contamination issues. It also protects machinery, contributing to longer equipment life and more stable system performance, while extended filter life supports lower running costs over time.

Approaching dust control as a combination of exposure, filtration efficiency and system longevity gives facilities a far more complete picture of how well their systems are performing and ensures worker health is always at the forefront of their business.

Connected safety: Why ownership and integration matter

In high-risk industrial environments, safety depends on visibility. Knowing where workers are, understanding the conditions they are operating in, and responding quickly when something goes wrong are fundamental to protecting people and maintaining operational integrity.

Today, connected technologies are transforming how organisations achieve this visibility. Gas detectors, wearable devices and monitoring platforms can provide real-time insights into worker safety, enabling faster decision-making and more proactive risk management.

As connected safety becomes more widely adopted, organisations are increasingly considering how these systems fit within their existing operations. Connected safety solutions can be broadly understood through two approaches: outsourced monitoring services and integrated safety ecosystems.

Two approaches to connected safety

Connected safety solutions typically follow one of two approaches.

The first relies on outsourced monitoring services. In this model, alerts and worker status updates are routed to an external monitoring centre that operates around the clock. When an incident occurs, third-party agents review the alert and escalate the issue if necessary.

The second approach centres on integrated safety ecosystems. Here, connected devices feed data directly into a unified platform used by the organisation’s own safety team. Alerts, reporting and insights remain within the company’s operational structure, supporting alignment with existing processes.

Both approaches aim to improve worker protection, but they are suited to different operational needs. For example, outsourced monitoring can support organisations without dedicated in-house safety teams to manage alerts at all hours or, equally, those with in-house teams working standard business hours. While integrated approaches enable organisations that have round-the-clock safety teams to handle alerts internally within their existing workflows.

Why integration and access matter

Safety teams not only respond to incidents, but also work to understand why they occur and how they can be prevented. This understanding can improve significantly with access to accurate, comprehensive data and the ability to analyse it within the context of daily operations, regardless of how alerts are managed.

It is important to consider where safety data is stored, how it is accessed, and who should act on it. Different models support different organisational needs. For example, outsourced monitoring can provide reassurance for smaller teams, while integrated approaches may suit larger organisations that can manage safety processes in-house at all hours.

An integrated approach enables safety teams to maintain direct access to the information that matters most. By connecting detection devices with safety management platforms, organisations can  help keep alerts, worker data and operational insights are readily available within their existing workflows.

Each approach offers different advantages depending on how safety is managed within the organisation. Where integrated systems are in place, safety teams can access and use data within their existing workflows, supporting a more proactive approach to safety management. This enables organisations to 

analyse patterns in exposure, identify emerging risks and refine safety procedures before problems escalate.

From monitoring to safety leadership

As industrial environments become more complex, the role of safety leaders is evolving. Today’s safety teams are expected not only to respond to alarms but also to shape strategies that prevent incidents altogether.

Systems that provide a complete view of safety performance across sites and operations can help safety leaders achieve these goals. Detection technologies, monitoring platforms and reporting tools can work together to create a single source of truth that supports faster, better-informed decisions.

For this reason, many organisations are moving towards integrated safety ecosystems rather than relying solely on standalone devices or external monitoring services. When detection technologies are designed to work within a broader safety platform, they become part of a connected system that supports both immediate protection and long-term safety improvement.

Supporting the next generation of Gas Detection

For industries operating in high-risk environments, such as entering confined spaces, gas detection remains a key component of this ecosystem. Workers need reliable instruments capable of identifying hazards while also feeding data into the wider safety strategy.

Modern gas detection technologies are increasingly designed with this integration in mind. By connecting detection devices with safety management platforms, organisations can gain real-time visibility into worker status and environmental conditions while also capturing valuable data for reporting and continuous improvement.

Solutions such as the ALTAIR io™ 6 Multigas Detector from MSA Safety are designed to support this ecosystem-led approach. By combining advanced multi-gas detection with seamless integration into connected safety platforms, organisations can enhance worker protection while maintaining control of their data and supporting compliance within existing safety processes.

Looking ahead

Connected safety is not simply about adding new technology to the workplace. It is about building systems that give organisations the insight and flexibility needed to protect workers effectively.

As connected technologies continue to evolve, organisations will gain the greatest value from solutions that integrate easily into their operations, support streamlined compliance processes and accountability, and provide clear, actionable insights to the teams who help keep people safe.

To explore how integrated gas detection can support a connected safety ecosystem, discover more about the ALTAIR io™ 6 Multigas Detector and the wider connected safety solutions from MSA.

In hazardous environments, pressure measurement equipment must do more than deliver accurate readings. It must also operate safely in potentially explosive atmospheres while maintaining reliable performance under extreme pressure conditions.

The HP1000 Series from ESI Technology combines both requirements in a single solution. Designed for pressures up to 5,000 bar (72,500 psi), the Intrinsically Safe HP1000 provides dependable pressure measurement for demanding applications in hazardous gas, dust, and mining environments. With ATEX and IECEx certification available on 4-20 mA versions, engineers can confidently specify the HP1000 for use in some of the world's most challenging industrial locations.

Designed for Hazardous Areas

Many industries operate in environments where explosive gases, vapours, dust, or combustible particles may be present. In these areas, safety is a critical consideration when selecting instrumentation.

The Intrinsically Safe HP1000 has been designed to minimise the risk of ignition by limiting the electrical energy available within the device. This allows the transmitter to operate safely within designated hazardous areas when installed as part of an approved intrinsically safe system.

With both ATEX and IECEx certification options available, the HP1000 offers a globally recognised solution for hazardous area pressure measurement. These approvals help simplify specification and installation for projects operating across international markets and industry sectors.

The HP1000 Series uses a unique one-piece titanium sensing assembly. Unlike conventional designs that rely on welded diaphragms, the HP1000 machines both the diaphragm and pressure housing from a single piece of titanium alloy.

This design eliminates welds within the pressure boundary, increasing strength and improving long-term reliability. It also provides excellent resistance to pressure spikes, shock loading, and cyclic pressure conditions.

Furthermore, titanium offers outstanding corrosion resistance, helping the transmitter perform reliably in aggressive industrial environments.

Proven Silicon-on-Sapphire Technology

At the heart of the HP1000 is ESI Technology's proven Silicon-on-Sapphire (SOS) sensor technology.

SOS technology delivers excellent accuracy, long-term stability, and repeatability. It also performs reliably across wide temperature ranges, making it particularly well suited to demanding industrial applications.

The sapphire substrate provides exceptional electrical insulation, helping to maintain stable performance even in harsh operating conditions. This allows engineers to achieve accurate pressure measurement throughout the transmitter's service life while reducing maintenance requirements.

The high-speed door is associated with protecting buildings and the manufacturing/storage activities within, says Doug Hart, chairman, Hart Door Systems. However, this mega climate event, which, at the time of writing, is delivering very high temperatures across Europe, is causing unheard of challenges for industry, the main one being high temperatures in manufacturing and storage areas.

Our highspeed door brand, Speedor, is in daily use across significant areas of industry. As Speedors help to maintain temperatures within a building so can Speedors be used to protect buildings from the inflow of very warm air.

Maintaining temperatures within a building is essential even if faced by external weather issues be they extreme cold or heat challenges. The key is to reduce the inflow of very warm air and it’s the speed of Speedor which helps to reduce that.
