What Is a Gas Detection Wearable?

 
     
 

 

 
     
     
   
     
     
 

The number of workplace injuries remains nearly unchanged year-over-year, with more than 2 million nonfatal workplace injuries and illnesses reported by provide industry employees in 2019.[1] And up to 90% of workplace injuries can be attributed to human error.[2]

 

While PPE has not traditionally had the technological capabilities to help prevent worker injury due to human error, the latest safety innovations, such as gas detection wearables, can help provide the visibility and data-driven insights to help your organization create an adaptable, proactive safety program and establish a culture of behaviour-based safety. Connected, wearable technology is leading the way for gas detection programs to evolve and enhance both their approach to worker safety and their approach to record-keeping, compliance, and fleet management.

 

But transforming your organisation to a connected program does not happen overnight. The first step is understanding the benefits of wearable technology and how a connected program can work for your organisation.

 

To start, what is a gas detection wearable? What are the benefits of connected safety technology? Here are answers to those top questions:

 

  1. What is a gas detection wearable?

 

A gas detection wearable is designed to be worn by each individual worker, on his/her person, while on the jobsite. With a wearable detector that can simply clip directly on to apparel or other PPE, such as a fall harness, lone workers can be monitored in real-time to help provide critical data points about on-site workers to off-site safety managers, including emergency monitoring.

 

A wearable device can be a useful way to monitor workers’ safety, location, and behaviors; however, it may not always be enough to help build a proactive, adaptable gas detection safety program over time.

 

But a wearable gas detector that comes with automatic connectivity can be much more impactful in terms of driving transformation, efficiency, and reaching long-term safety and productivity goals of a gas detection program.

 

  1. What does the term “connected” mean for gas detection hardware?

 

The term “connected” not only means a connected device – one that comes with out-of-the-box, cutting-edge cellular connectivity through leading national networks – but also a comprehensive solution inclusive of hardware software. It’s not necessarily enough to simply have cellular connectivity; hardware should also be connected to software, so that connectivity can provide the real-time data and insights to help drive adaptable, proactive safety programs.

 

This connectivity transforms hardware from traditional PPE to a technology-based, future-forward solution. Successful integration of this advanced technology requires that not only are devices smarter and capable of providing visibility and insights to help curb risk, boost productivity, and simplify compliance, but also that they continue to perform with the durability and functionality to maintain their first and foremost mission of helping to protect the worker. As a wearable device, the detector should maintain the IP-rating, sensor technology, and battery life expected of today’s most durable portable gas detectors.

 

A wearable device that comes with automatic connectivity right out-of-the-box allows for quick and seamless implementation, no IT required.

 

  1. How can wearable, connected technology help improve worker safety?

 

The most common industries for lone workers include oil and gas, telecommunications, utilities, construction, and industrial contractors. With wearable devices, safety managers can help ensure these lone workers are not completely alone. By digitally assigning a wearable device to individual workers at the start of each shift, safety managers can gain insight into key individual worker data including:

  • Compliance of device use and faulty safety behaviours, including turning off an instrument or changing settings
  • Workers’ locations, gas readings, and alarms
  • Safety behaviours in the field, and whether new training specific to individuals is needed

 

A connected work program for gas detection can provide the visibility that is needed to manage large teams of workers and help establish a behaviour-based culture of safety. With real-time visibility of lone workers, safety managers can help make sure those workers are protected, with instant alerts. And connected hardware and software solutions can provide real-time data such as worker location and how the detector is being used by each worker – which can all help inform safety training to both drive worker safety day-to-day and enhance an organisation’s safety culture over time.

 

 

  1. How can wearable technology improve worksite safety?

 

It can be difficult to difficult to manage assets across different worksites and keep remote teams safe and productive. Connecting worksites with wearable, connected technology gives safety managers visibility into:

 

  • Teams and assets, including worker position and activities and which devices require maintenance
  • External and environmental factors, such as temperature or humidity
  • Equipment status, maintenance, and asset management information across all worksite locations
  • Centralised reports and data logs for automated compliance
  • Intelligent mapping and zone segmentation, automated digital follow-ups, alarm sharing, and heatmapping to help drive operation-wide safety

 

With notifications available on both desktop and mobile devices, safety managers can get alerts when alarm exposure or SOS event occurs. Other details such as GPS location, gas readings, and compliance data are readily available within these immediate notifications provides safety managers with the visibility needed to manage safety and productivity across multiple worksites at once, all from remote, off-site locations.

 

  1. How can wearable technology improve compliance and accountability across an organisation?

 

Since a non-compliant detector can lead to potentially disastrous outcomes, it’s essential to ensure that every device is optimised. In other words, every device operates and protects the worker as it should. Technology not only makes this possible, it also makes it seamless. Advanced features that wearable technologies for gas detection should include are:

 

  • Automatic bump tests and calibration when devices need it
  • Visual indicators with green, yellow, and red lights representing “compliant,” “non-compliant,” and “in alarm,” respectively
  • Device lock out to ensure that non-compliant devices are not inadvertently used
  • Real-time historical data into specific workers

 

 

  1. Can wearable devices help improve compliance and overall workflows?

 

Connected wearable devices allow you to connect workflows across your organisation by providing insight into compliance and productivity issues. This information, coupled with connected cloud-based software, can allow you to:

 

  • Automate compliance and help to reduce false alarms, remove asset-related risks, and lower the cost of downtime
  • Determine if instruments have been configured correctly and are compliant in testing and while in use
  • Create comprehensive reports in an industry standard format

 

 

  1. What type of investment should an organisation anticipate for implementing new wearable and connected technology across their workers and worksites?

 

With the latest technology, often comes newer business models to help drive your organisations’ transformation to a connected safety program. Subscription models that include both detector hardware and software options can help enable faster implementation, along with increased warranty coverage and ongoing software and firmware upgrades.

 

The right partner can help support your organisation’s connected safety journey with the right solution to fit your needs, from the number of wearables to various software options and features capabilities, giving you flexibility.

 

A seamlessly integrated solution of connected wearables and cloud-based software can provide visibility of your workers, worksite, and workflows that can make all the difference and help organisations drive a proactive safety culture over time.

BSIF launches checklist to take the risk out of buying PPE

With an increasing volume of substandard products on the market, the British Safety Industry Federation (BSIF) has issued a handy checklist to help specifiers and users check whether personal protective equipment (PPE) is fit for purpose.

BSIF analysis carried out last year showed that much of the PPE on the market fails to match up to the advertised protection.  

It completed tests on 127 non-member products, which included checking their compliance with relevant standards and testing whether they perform as claimed. Only 18 (15%) of these products were fully compliant. This means 108 products (85%) failed to meet the regulatory criteria, many of which are still for sale to unsuspecting users. 

The findings around non-member products contrast with the results of tests on products supplied by BSIF Registered Safety Suppliers, whose products are tested annually as part of the scheme’s audit process. Of 387 tests completed on Registered Safety Suppliers’ products, 332 (86%) passed immediately, and of the 55 (14%) that initially did not meet the test criteria, all issues were subsequently resolved.

The new BSIF PPE checklist has been created to help specifiers and users ensure that PPE complies with the law and conforms to PPE Regulation 2016/425. It presents a series of questions to ask when purchasing PPE, which are divided into sections for ease of use: Product Markings, Required Documentation, Product Condition, and Storage.  

Examples of questions included in the checklist are: 

  • Does the PPE have a UKCA, UKNI or CE Mark applied to it?
  • Was the PPE issued with User Instructions included?
  • Is there a Declaration of Conformity with the PPE
  • Is the PPE clean, undamaged and suitable for use?
  • Was the PPE stored correctly, according to the User Instructions?

If any questions present cause for concern, users are advised to seek support and guidance from their company’s health & safety advisor and the manufacturer of the PPE. The BSIF can also provide general guidance.

BSIF CEO Alan Murray says: “This checklist is a reminder that while anyone can sell safety, you shouldn’t buy safety from just anyone. Failing to check your PPE is fit for purpose could leave you or your employees, for whom you have a duty of care, vulnerable and unprotected, and also expose your organisation to the risk of prosecution. The easiest way to check your PPE is compliant is by only buying from a Registered Safety Supplier.”  

 

The checklist can be downloaded for free at: Check-your-PPE.pdf (bsif.co.uk) 

 The BSIF also offers anIs it Genuine – Certification Checklist’ that provides further advice on how to check if the supporting documentation for your PPE is genuine and what to do if you are concerned.

Belzona’s New Epoxy Structural Adhesive Provides Metal Cold Bonding Solution

Facilities maintenance operations can face different circumstantial challenges which require modern solutions. Particularly for hazardous environments such as the oil & gas and petrochemical industries, cold-curing polymeric repair and protection materials can provide a novel means of bypassing these challenges.

This application demonstrates a Customer’s use of Belzona’s cold-curing epoxy two-part structural adhesive, Belzona 7311, to navigate these challenges in the petrochemical industry to fulfil their maintenance needs.

Pic1.jpeg

This metal tank needed maintenance to both the base and the roof

Pic2.jpeg

The structural epoxy adhesive, Belzona 7311, provided a cold bonding solution for the metal substrate

What was the Problem?

A metal storage tank in a Chemical Plant containing concentrated sulfuric acid required maintenance to both the base and the roof. The Customer needed to bond pipe supports to the top of the tank to reinforce the pipes directly above. However, the tank was installed with a rubber lining, ruling out hot work such as welding as a means of attaching the pipe supports.

Meanwhile, the existing tank base coating had been exposed to chemical attack and needed to be replaced with a suitable chemical-resistant coating to protect the tank from future chemical spills.

Pic_3.jpeg

The tank base had been exposed to chemical attack

The internal rubber linning made welding inappropiate to bond the metal pipe support  

Belzona 7311: A New Cold Bonding Solution

Belzona’s first ever structural adhesive, Belzona 7311, proved to be the optimal cold bonding solution for the Customer’s requirements due to its high mechanical strength, cleavage and shear resistance. By using this technology, the supports could be cold bonded to the top of the metal tank without the associated risks of welding such as damage to the rubber lining and metal distortion known as Heat Affected Zones (HAZ). HAZ can be the result of the intense process of heating and cooling the substrate, leading to weaknesses in the metal and compromising the integrity of the weld joint.

Bonding of the Pipe Supports

The Contractor specified that the best way of attaching pipe supports was to cold bond six 254 mm by 254 mm (10 inch by 10 inch) metal plates to the top of the tank, which could then be cold bonded to the pipe supports. The chosen areas were marked with tape, before being prepared using handheld surface preparation tools. The application areas were prepared to SSPC-SP11 standard, producing a bare metal surface and a minimum 25 μm (1 mil) profile for a high level of adhesion.

The two-part epoxy adhesive, Belzona 7311, was then mixed and applied to both the substrate and the underside of the metal plates, before being held in place with no additional weight or pressure

while the product was allowed to cure. Once the plates had been cold bonded to the metal tank, the pipe supports were subsequently attached to reinforce the pipes in operation above the tank.

The cold bonding solution was allowed to cure with no extra weight or pressure

Application of the Chemical Resistant Coating

Belzona 4311 (Magma CR1) was specified to protect the tank base due to its chemical resistant qualities, having encountered no significant deterioration after a year of immersion in up to 98% sulfuric acid at 40°C (104°F), when tested in accordance with ISO 2812-1.

The previous tank base coating was removed and the concrete surface was prepared with an ATEX-rated power tool and conditioned using Belzona 4911 (Cleaner/Degreaser) to ensure maximum adhesion for the new coating.

Two coats of Belzona 4311 (Magma CR1) were applied to provide long-term protection to the tank base, avoiding the harmful financial, safety and environmental consequences of a future leak.

Results of the Repair

The sulfuric acid tank base will be protected against chemical attack for the long term due to the chemical resistant properties of Belzona 4311 (Magma CR1). Meanwhile, the Customer was impressed by the ability of Belzona 7311 to solve the challenges caused by the tank’s rubber lining, cold bonding the metal pipe supports securely without the need for welding. The Customer was also very satisfied by the high mechanical strength, cleavage and shear resistance demonstrated by the cold bonding solution during the application.

Pic11.jpeg

The strength of the cold bonding solution allowed the pipe supports to be seamlessly attached to the top of the tank

Cold Bonding Solution in Action

This application presented an example of the opportunities provided by the epoxy two-part structural adhesive, Belzona 7311 as a cold bonding solution, offering an effective and safe alternative to welding. The solution can be used for structural bonding applications requiring high mechanical strength, cleavage and shear resistance, including ladders, handrails and plate bonding, and is suitable for harsh service environments.

How to handle chemical hazards?

Chemical hazards in industries can cause serious harm to workers and the environment. To prevent these hazards, it is essential to have visual warnings and inspection recording in place. Visual warnings, such as labels, signs, and placards, can alert workers to the presence of hazardous chemicals and inform them of the proper precautions to take.

The purpose of the Chemtag is in case there is an accident or incident where the chemicals are stored or with a person coming into contact. It pulls the pertinent information off the COSHH safety data sheets and makes it immediately available for first aid or medical purposes.

1 = what fire extinguisher is required

2 = what's the immediate first aid action

3 = what's the immediate spill response

So the fire brigades know what they're dealing with, and the ambulance can take the card, take the person and away they go.

Designer and Project Engineer Ex Training and Competence

Many of you will be aware that the Ex-Standards aimed at end users(such as IEC60079-14) have very specific requirements for competence. These can include both ‘knowledge’ and ‘skills’ assessments and the need to retain and be reassessed regularly. ‘Installers’ have historically had to have some form of special certificationto be allowed to work in Hazardous Areas (for Example, CompEx 01-06) but it is now also the case that people involved in design and equipment selection will also be asked for their qualifications and evidence of competence. 

In addition to the current requirements of the users’standards, a new standard (initially a technicalspecification) is being developed specifically covering Ex Competence (IEC TS 60079-44 Personal Competence) so now is a good time to refresh our memory on the role of the designers and project engineers

Ex Design Competence

The requirements for personnel involved in the process of designing plant or equipment for use in potentially explosive atmospheres (including equipment that may be in the safe area but have functionality involved in the safe explosion prevention or mitigation) should be given serious consideration. 

Reviewing case studies of many recent explosions will demonstrate that it was the fundamental design that was unsafe, even when correctly built and installed (such as an incorrectly specified level switch or an impractical maintenance procedure post installation).

The requirements will obviously be applicable to companies who design plant but are equally applicable to project engineering companies or manufacturers who may provide rigs, skids or assemblies (now covered by IEC TS 60079-46that may or may not utilise certified hazardous area equipment. (ExVeritas offer specific course for ‘Assembles’ that cover these specific risks and challenges for ‘manufacturers’ as well as end users)

According to the Installation Standard, Designers must possess, to the extent necessary to perform their tasks, the following skills:

• Detailed knowledge of the general principles of explosion protection; this would include knowledge of terms such as LEL, MESG, Flashpoint and factors that affect dust and gas explosion properties (pressure, temperature, oxygen etc).
• Detailed knowledge of the general principles of types of protection and marking; this would include all of the electrical concepts such as i.c.m.a. op is, Non-electricalhetc., group markings such as IIB+H2 (Gas) or IIIC (dust) and EPL’s such as Ga/Gb.
 
• Detailed knowledge of those aspects of equipment design which affect the protection concept; this may include SIL if safety systems or protective systems are used and in-depth design knowledge if concepts such as constructional safety (c) or IEC special safety (s) are used.
 
Detailed knowledge of content of certificates, such as use of the ‘X’ or ‘U’ and the many different certificate types and issuing bodies. It is also important to make sure these corticates are to ‘current’ Standards and not certified to ‘withdrawn’ standards! 
 
An understanding of practical skills for the preparation and installation of relevant concepts of protection (full knowledge of the installation requirements).
 
Detailed knowledge of the additional importance of ‘Permit to Work systems’, safe isolation and ‘risk assessment’ in relation to Explosion Protection; Process and procedure documentation – most explosions occur during startup/shut down or maintenance!
 
Detailed knowledge of the techniques to be employed in the selection and installation of equipment referred to in IEC/EN 60079-14 and a general understanding of Inspection and Maintenance requirements of IEC/EN60079-17.
 

Designers must be able to demonstrate their competency and provide evidence of attaining the knowledge and skill requirements specified above, relevant to the types of protection and/or types of equipment involved. They must also be able to demonstrate their competency with documentary evidence such as ‘Designers training Certificates’ to the user and suitable documented safe operating procedures and list of required checks and maintenance (including intervals). 

One of the most used and widely accepted levels of certification for Designers is CompEx EX12, it is also worth noting that CompEx has also added an introductory Functional safety course to their portfolio which is useful alongside EX12.

Full details of the new CompEx Courses can be found here: CompEx Training and Competence Certification or email This email address is being protected from spambots. You need JavaScript enabled to view it. for a prospectus.
