FOUR GAS MONITOR — GAS DETECTION FOR COMPLEX ENVIRONMENTS

When facing unknown environmental hazards invisible to the body’s senses, a gas detector is the first line of defense for worker safety. Portable gas detectors are often part of personal protective equipment (PPE) mandated by businesses and designed to keep personnel safe. Personal four gas monitors or detectors continuously evaluate a worker’s environment for multiple gas hazards. A four gas monitor provides comprehensive gas detection coverage for complex working environments when there is a risk of injury, illness or death from potentially toxic or explosive ambient gases.

WHY A FOUR GAS MONITOR VERSUS A SINGLE GAS DETECTOR?

Hazards posed by gases can be classified into three categories: toxic, asphyxiating and combustible. Four gas monitors are typically configured with sensors to address each of these scenarios for a given worksite or scenario. For example, in the energy industry, sour gas presents a significant risk of hydrogen sulfide (H2S) exposure to workers. Many businesses supplement monitoring of H2S with combustible gases, oxygen and carbon monoxide. Combustible gas sensors are a smart addition to locations where natural gas is present with H2S, addressing the detection of a potentially explosive atmosphere. Everyone requires oxygen, which can be displaced by other gases, causing a deficiency. Further, incomplete combustion can generate carbon monoxide, an asphyxiating gas.

G7 IS A LEADING FOUR GAS MONITOR

A four gas monitor is often a smart investment for many industries and applications. Blackline Safety’s G7 connected gas detection system delivers an exclusive customizable, modular design, providing tailored comprehensive gas detection for every work scenario. Quad-gas cartridges turn G7 into a four gas monitor and are compatible with a selection of gas sensors.

G7 with a Quad-gas Cartridge is a highly configurable four gas monitor that is compatible with a range of gas sensors including combustible gases, hydrogen sulfide, carbon monoxide and oxygen. Other sensors are currently under development to expand our line of available sensors.

Let us know about your gas sensor requirements.

UNSEEN HAZARDS

Oxygen sensors will alert for both oxygen-enriched and depleted environments. Oxygen enrichment (more than 23.5%) occurs when oxygen concentration exceeds that of fresh air, potentially increasing the risk of combustion of flammable gases. Oxygen deficient environments (less than 19.5% oxygen) present a suffocation hazard and can impact the body’s respiratory system in seconds. Other gases, toxic or not, can displace oxygen, creating a hazardous atmosphere that impairs worker respiration.

Combustible gases pose a risk of explosion. LEL sensors detect the concentration of flammable or explosive gases and alert the user if the level of gas surpasses the pre-configured concentration below the lower explosive limit (LEL), well before the potential for explosion occurs.

Toxic gases are often fast acting and, depending on the concentration, can impact systems within the body very quickly or can pose a longer-term health risk. Electrochemical gas sensors, such as for carbon monoxide (CO) and hydrogen sulfide (H2S) alert well before toxic gas levels reach harmful concentrations.

G7 FOUR GAS MONITOR SENSORS

G7 supports three main gas detection sensor types that accommodate the monitoring of toxic, asphyxiating and combustible gases.

ELECTROCHEMICAL GAS SENSORS

  • Hydrogen sulfide, carbon monoxide and oxygen (pumped)
  • Monitor Short Term Exposure Limits (STELs) and Time Weighted Averages (TWAs)

CATALYTIC (PELLISTOR) GAS SENSORS

  • Detects combustible gases through controlled oxidation
  • Does not work well in an oxygen-depleted environment
  • Measures from 0-100% of the LEL
  • May not give a reading when above 100% LEL

INFRARED (IR) GAS SENSORS 

  • Detects combustible gases through IR absorption
  • Do not require oxygen to accurately function
  • Measures 0-100% LEL

INDUSTRIES WELL SERVED BY A FOUR GAS MONITOR

Hazardous gases vary from industry to industry, based on materials being handled and naturally-occurring environmental conditions. Comprehensive gas detection with a four gas monitor accommodates for diverse gas threats that employees can face in the line of work.

OIL AND GAS

  • Toxic hydrogen sulfide (H2S) gas is present in sour natural gas
  • Carbon monoxide (CO), an asphyxiating gas that may be generated from incomplete combustion
  • A gas leak can displace oxygen, posing a risk to the worker
  • Hydrocarbon gas leaks, such as natural gas, can pose an explosion risk

WATER AND WASTEWATER

  • Methane gas can be generated by biological processes that break down wastes, posing an explosion risk
  • Toxic hydrogen sulfide can be generated by biological processes

 MINING

  • Like water and wastewater facilities, mining operations also pose the risk of methane and H2S exposure. Additionally, carbon monoxide may be present — a toxic gas capable of depleting oxygen levels. In these cases, both LEL and electrochemical sensors are required for comprehensive detection coverage of possible gas exposures.

 CONSTRUCTION

  • Heaters that operate during cold weather can generate carbon monoxide if propane or natural gas combustion is hindered

G7 devices with a Quad-gas cartridge provide safety monitoring and gas coverage for a variety of complex working environments. The quad-gas cartridge supports up to four gases, but can also be configured for two or three gas sensors.

MAINTAINING FOUR GAS MONITORS

Proper maintenance and calibration are necessary to ensure reliable four gas monitor performance and accuracy — improper maintenance can lead to inaccurate readings or failure to detect a sensor that is not working.

OSHA recommends developing standardized procedures to ensure calibrations and proper usage, including the documentation and verification of proper maintenance. Calibration refers to measuring an instrument’s accuracy relative to a known traceable concentration of a test gas. It is important to calibrate devices to environmental conditions that are the same or close to real-world work conditions. Further, ISEA recommends verifying the operational capacity of gas detection sensors (bump testing), before each shift, plus regular calibration.

Blackline’s G7 Dock offers a cost-effective solution to perform bump tests and calibrations while minimizing the amount of calibration gas used. We’ll highlight our G7 Dock in an upcoming blog article.

RED DOT AWARD — G7 GAS DETECTOR IS INTERNATIONALLY RECOGNISED

Blackline Safety’s G7 wireless gas detector and connected safety solution has been awarded a sought-after Red Dot Award. The expert jury panel, comprised of 39 product designers, professors, architects, ergonomic engineers and other industry leaders, selected G7 as the winner of a Red Dot Award: Product Design 2017 from over 5,500 submissions sent in from 54 countries, for its innovation and design quality.

The Red Dot Awards: Product Design is recognised as one of the world’s most prestigious design competitions, awarding only products that feature outstanding design. Headquartered in Essen, Germany Red Dot initially convened more than 60 years ago to assess the best designs of the day. Since then, the Red Dot jury has been awarding their seal of quality for exceptional products of the year. Manufacturers and designers around the globe entered their products in the 2017 competition and were judged on degree of innovation, functionality, ergonomics, durability and overall quality of design.

 

“THE RED DOT WINNERS ARE PURSUING THE RIGHT DESIGN STRATEGY,” SAID PROFESSOR DR. PETER ZEC, FOUNDER AND CEO OF THE RED DOT AWARD. “THEY HAVE RECOGNISED THAT GOOD DESIGN AND ECONOMIC SUCCESS GO HAND IN HAND. THE AWARD BY THE CRITICAL RED DOT JURY DOCUMENTS THEIR HIGH DESIGN QUALITY AND IS INDICATIVE OF THEIR SUCCESSFUL DESIGN POLICY.”

 

DEFINING THE WIRELESS GAS DETECTOR OF THE FUTURE

Industrial work for employees can be risky. Many organisations use a personal gas detector to monitor for toxic or combustible gases, but they are traditionally disconnected and cannot call for help. With G7 a new level of personal safety is defined — as the world’s first wireless gas detector with 3G wireless, two-way speakerphone and live monitoring, G7 provides comprehensive safety coverage for even the most hazardous working conditions. With constant connectivity, every incident is communicated and managed in real-time, allowing teams to deliver optimised emergency responses tailored to the situation.

 

“THE HALLMARK OF ANY GOOD DESIGN IS ONE THAT ENABLES USERS TO DO NEW THINGS WITHOUT THINKING TOO MUCH ABOUT IT,” SAID BARRY MOORE, VP PRODUCT DEVELOPMENT AT BLACKLINE SAFETY. “G7 NOT ONLY LOOKS GREAT, BUT MORE IMPORTANTLY IT MAKES AN EMPLOYEE’S JOB EASIER BY COMBINING THREE DEVICES INTO ONE — A GAS DETECTOR, A LONE WORKER SAFETY DEVICE AND A COMMUNICATION TOOL. THIS AWARD RECOGNIZES THE EFFORTS OF OUR DEDICATED DESIGN TEAM WHO DEFINED A NEW LEVEL OF PERSONAL SAFETY FOR OUR CLIENTS.”

 

G7 features an exclusive modular design to support customisation that caters to diverse working conditions. Gas detection is customised to teams’ working environments with the choice of field-replaceable single- or quad-gas cartridges, and a selection of gas sensors including combustible gases, oxygen, carbon monoxide, and hydrogen sulfide. G7 solves the old problem of replacing sensors inside a gas detector, traditionally requiring a device be removed from the field for maintenance, with the Blackline Cartridge Replacement Program. Cartridges arrive ready to use and can be easily switched out on-site, increasing product up-time and fleet efficiency without teams having to worry about complex ordering processes.

OUTSTANDING WIRELESS GAS DETECTOR DESIGN MEETS CONNECTIVITY

Should a fall, no-motion or dangerous gas level be detected, G7 instantly connects workers with the Blackline 24/7 Safety Operations Centre, teams. Using seamless 3G or satellite connectivity, G7 gas detectors communicate environmental conditions in real-time directly with Blackline’s teams, who are then empowered to mobilise the appropriate response based on businesses’ pre-determined response protocols. The safety operations teams also leverage wireless gas detection insights to notify responders of possible hazards to be prepared for during emergency responses, should they need protective equipment or respirators— keeping everyone involved informed and safe.

A beautiful appearance is not enough — a Red Dot Award is presented only to those products that help users cope with daily life, to make working environments safer, or to make daily activities more comfortable. The Blackline Live web portal is a core of the G7 wireless gas detector solution — as an alert management tool, the portal serves up all pertinent information needed to deal with an emergency effectively. Available on desktop or mobile, Blackline Live provides easy wireless gas detector management, employee location mapping and alert management tools. When designing Blackline Live, we understood that the people requiring safety solutions aren’t always those wearing the equipment or the ones that are in the field. The people that need and value the safety information are often safety managers, operations teams, industrial hygienists or first responders. Blackline Live is the window they need to get useful, necessary and timely information easily. G7 wireless gas detectors are easily configured through the portal for specific working environments, where alert settings, emergency protocols and calibrations schedules are managed.
