Multi-Gas Detection Equipment for Mining, Tunneling, Water & Industrial Applications

Multi-Gas Detection Instruments for Mining and Tunnelling

Putting safety first is essential for both the wellbeing of miners and the legal compliance of mine companies. Both put their trust in Carroll Technologies Group every day for their mine safety product needs. That includes mining gas detection equipment.

Methane becomes highly inflammable and even explosive at atmospheric levels as low as five to 15%. Carbon monoxide levels as low as 0.1% are liable to cause fatality within just a few minutes, and it can take as little as 30 seconds of oxygen deprivation for a miner to lose consciousness.

As such, it’s vital for mine workers to be able to detect changes in their atmosphere immediately.

Gas Detection Equipment – Portable Multi Gas Detectors for Mining, Tunneling & Water Industries

A multi-gas detector can be produced in both portable and fixed formats. Portable detectors allow miners to test the atmosphere of confined spaces prior to entry, trace leaks, and provide early warnings of the presence of dangerous gases.

Fixed detectors can be installed in high-risk areas where flammable gases could accumulate to be constantly monitored – making the technology useful for the tunneling and water industries, as well as for mining operations.

One device supplied by Carroll Technologies Group in a fully portable format represents the very highest caliber of gas detection technology – the Mine Safety Appliances (MSA) Altair 4X Detector.

Assembled to order, the device offers a 4-year operational life, and can alert the user to the presence of combustibles, toxins, and anaerobic environments in 15 seconds. It also has improved reusability and accuracy compared to previous models, and a lower maintenance cost.

The device is estimated to have a four-year working life, and comes with a manufacturer’s instrument warranty of three years.

The Altair 4X also comes with MotionAlert™ as standard in all mining gas detection equipment. This technology activates an alert when no movement is detected from the user for 30 seconds or longer, should they be injured or unconscious.

Users are also able to manually activate the InstantAlert™ alarm, which utilizes the device’s alarm system to quickly and efficiently warn others of hazards in the near vicinity.

The software can be easily connected to a PC for simple data management, and is dust and water resistant. Its 30-hour runtime allows for continuous operation over three shifts, and its chunky, ergonomic design allows it to be easily operated even if the user is wearing gloves.

Gas Detection Solutions for the Water Industry

The water industry relies on gas detection solutions when undertaking work as part of tunneling or pipeline construction projects. Gas detection systems protect workers in the water industry by providing a vital safety net for such projects, through mitigating the potentially life-threatening risks of explosions or toxic gas inhalation. Carroll Technologies provides an extensive range of gas detection solutions which are effective for application within the water industry, helping to reduce costs and increase worker safety.

Molded Case Circuit Breakers for Use in Mines and Tunnelling

Electrical equipment

An MCCB is a vital piece of apparatus for electricals where load current will exceed the capability of a miniature circuit breaker, and is essential for both the safety of mining staff and the longevity of the equipment they use every day.

Molded Case Circuit Breakers for Use in Mines and Tunneling: Risk Prevention

MCCBs are triggered in cases of thermal overload, short circuit, and ground faults. When these events occur, the MCCB will use its electromechanical trip units to safely halt the flow of electric current. This helps to minimise a mine’s risk of fire, explosion, or related hazardous events.

Carroll Technologies Group offers the widest range of electronic equipment available to mine owners across North America, including a range of mining MCCBs from Eaton.

Eaton Molded Case Circuit Breakers

Eaton EHD3010 Series C NEMA F-frame

Eaton EHD1010 Series C NEMA F-frame

Both new and factory serviced, each mode is a high-quality product which guarantees mine owners efficient running and a safe working environment for their employees.

Eaton’s 40-year commitment to the mining industry means their MCCBs can be relied upon to provide the very best in circuit-breaking technology.

The products have been extensively tested for reliability in hazardous mining environments, designed collaboratively with engineers from several reputable coal companies.

Eaton’s mining Molded Case Circuit Breakers are designed to protect all sizes of trailing cable, with minimal panel design and inventory requirements, and come in seven frame sizes to fit your individual needs.

The majority of units can also be installed in the field, allowing for simple on-site customization and replacement.

Field testing is also straightforward, as each MCCB includes a convenient built-in test port, compatible with the 120 Vac test kit.

Likewise, mechanical testing couldn’t be easier, with a push-to-trip button on each unit which can be triggered to confirm functionality during routine maintenance.

Eaton’s 310+ electronic trip unit technology means these MCCBs are triggered faster than microprocessor-initiated instantaneous trips.

The peace of mind delivered by these technologies is second to none, guaranteeing “faster than instantaneous” clearing times and enhanced safety measures.

Maintaining Your Mining Circuit Breakers

With an Eaton MCCB, you’ll always be able to visit a Breaker Service Centre (BSC) to maintain your device.

If it maintains minor physical damage or general wear and tear, BSC staff will be able to restore your device to full functionality. Should a device be beyond repair, Eaton offers credit toward the purchase of a new MCCB in exchange for the old model.

Miner using self contained self rescuer (scsr)

Our Miners Self-Rescuers

View our range of SCSRs in our products shop or get in touch to discuss your requirements.

Despite all safety precautions, accidents can and do happen, and a fire or explosion in a mine or tunnel could leave workers without rescue for some time.

Should an employee need to await help following a crisis or make their own way to safety, they must be able to do so with access to uncontaminated, breathable air.

Self-rescue breathing apparatus can provide a vital lifeline in an emergency, and is an integral piece of the miner’s equipment arsenal.

Self-Contained Self-Rescuers: Our Range

Among our range of SCSRs is the Mine Safety Appliances (MSA) W65 Self-Rescuer Respirator, an air-purifying oxygen mask designed to protect against carbon monoxide and other toxic gases emitting from underground mine fires or explosions.

Immediately ready-for-use, the latex-free mouthpiece and nose clip allow for a smooth flow of safely breathable air to the user. Designed to be strapped to the head permitting hands-free operation, the device can be carried on the belt or over the shoulder when not in use.

The hermetically sealed, stainless steel container of the W65 mining self-rescuer boasts a long life expectancy of up to 15 years, with an in-service life of 10 years, and can provide a wearer with clean air for up to four hours.

We also offer self-rescuer respirators products from Ocenco, such as the EBA 6.5. This closed-circuit apparatus uses compressed oxygen, rather than the chemical-based breathing solutions available from alternate vendors.

This allows for extended life of the product as these units can be repaired and refurbished after use where others cannot, giving the wearer with the security of a 15-year useful life.

A clear case allows the miner to quickly and accurately assess the condition of the device, which can be manually adjusted to provide the user with up to eight hours of respiratory protection.

Another Ocenco SCSR available is the M-20, a belt-borne device which is particularly useful in tunnels and other confined spaces.

At just over six inches square and three inches thick, this is the world’s smallest SCSR, using compressed oxygen to provide respiratory protection for up to 32 minutes.

The user can quickly check the oxygen supply through the clear case, and much like the EBA 6.5, this is a device which can be upgraded and maintained for up to 15 years.

Collision Prevention Systems in Industrial Applications

Any industry that deals with heavy-duty vehicles will understand the importance of collision prevention systems. According to the U.S. Bureau of Labor statistics, contact with objects/equipment is one of the top three causes of injury or even fatality for industry workers, from oil & gas extraction to coal mining to construction. In fact, 2020 statistics show that 716 US industry workers lost their lives due to contact with equipment.

Carroll Technologies is dedicated to finding the best equipment and working with industries to calibrate custom safety solutions ideally suited for the application to ensure that workers are kept safe, even in the most adverse of environments.

Collision Prevention Systems for Heavy-Duty Vehicles

The basis of most collision avoidance solutions is an effective tracking system, which can monitor the positions of workers and pieces of equipment to ensure that they don’t come into contact with one another. This can take the form of tags, worn by workers and attached to machinery and vehicles, which feed information into a control centre, ensuring a human operator can see the relative position of everything.

These collision avoidance systems also include alarms and alerts that trigger when two tags are moved too close to one another, providing an early collision warning system to prevent collisions from taking place.

These proximity detection functions can be customized, enabling larger or smaller safe zones to be established for individuals and machines of different sizes, creating a system where alarms are tailored to the scale and function of individual operations.

Large, above-ground operations may also utilize GPS tracking. While satellite solutions require companies to have access to this level of technology, they can save on operational costs and minimise equipment usage in the long-term, as satellite tracking removes the need for individual people and objects to be tagged.

Holistic services are increasingly popular, with companies such as Carroll offering tracking and communication services using the same technological base, and could significantly reduce the likelihood of collisions.

Collision prevention systems provided by Carroll include PBE’s collision avoidance system, which uses EM (electromagnetics), RFID, GPS and bi-directional radar at the same time for accuracy that can be configured to recognize different groups (such as vehicle types or personnel). Additionally, the dash-mounted PAS-Z Proximity Alert System alerts drivers to the presence of personnel, vehicles and obstacles.

The PAS-ZR is a ruggedized version of PBE’s standard collision avoidance system, specifically designed for both above and below ground vehicles in the construction and mining industry.
