That’s where Distributed Antenna (DAS) Systems can help. The above concern is not just an inconvenience for everyday two-way radio and mobile phone users; it can also affect life-saving communication to those who work in hazardous conditions such as mines, tunnelling systems, existing buildings and new construction projects.
Many authorities are now setting standards for connectivity and emergency responder coverage as a prerequisite for obtaining certificates of occupancy for new buildings.
One solution is the use of distributed antenna systems (DAS) and equipment which can also be very beneficial to the mining and tunnelling industries.
DAS for mines, tunnels and buildings are an organisation of spatially placed antennas, coax, and splitters that provide radio frequency (RF) coverage within a structure or geological area that does not have adequate signal levels.
How do DAS for Mines, Tunnels and Buildings Work?
Antennas are attached to a bi-directional amplifier which boosts the RF signal that it receives from the donor antenna and transmits out the network of coax and antennas to provide RF coverage as needed.
DAS can either be active or passive. In an active system, the signal is distributed through fiber optic cables to remote units which then distribute the signal to the mining antennas to amplify and boost signals along the route as required.
A passive DAS, on the other hand, simply uses bi-directional amplifiers, coax, splitters and diplexers to distribute the RF signal as needed.

Large vehicles, restricted access routes, blind spots, changing site layouts and high-traffic working areas can all increase the risk of collisions between machines, vehicles and personnel. Sophisticated proximity alert systems and proximity detection devices help operators, drivers and pedestrians identify potential hazards before they become incidents.
Carroll Technologies Group supplies a range of proximity warning and proximity detection solutions from leading manufacturers including PBE and ELOKON, helping industrial operators improve safety around mobile equipment, vehicles, forklifts and personnel.
Proximity Warning Systems and Proximity Detection Devices for Industrial Safety
Restricted access, reduced visibility, blind corners, congested travel ways and busy loading areas can all increase the risk of equipment-related incidents.
These risks are present across many industries, from mines and construction sites to warehouses, maintenance facilities, manufacturing plants, rail yards and industrial worksites. Wherever heavy vehicles, mobile equipment and pedestrians operate in close proximity, site managers need reliable ways to reduce collision risk.
Proximity alert systems are designed to help by creating warning zones around vehicles, equipment or people. When another vehicle, pedestrian or object enters a defined zone, the system can trigger visual, audible or vibration alerts, giving workers and operators more time to respond.
Depending on the system and application, proximity detection technology can also support geo-fencing, pedestrian detection, vehicle-to-vehicle alerts, speed reduction, access control and real-time situational awareness.
Reducing Collision Risk With PBE Proximity Alert Systems
Carroll Technologies Group supplies PBE proximity alert systems designed to support safety in demanding industrial environments, including mining and other heavy equipment applications.
PBE’s PAS-C Proximity Alert System uses detection technology to help identify vehicles, obstacles and personnel within defined zones. Sensors worn by workers or fitted to vehicles and machinery allow the system to monitor relative positioning and alert users when a potential hazard is detected.
The system can help operators establish configurable warning zones around mobile equipment, supporting safer vehicle movement in areas where visibility may be limited or personnel may be working nearby.
When a warning zone is breached, the system can trigger alerts to warn workers and operators of the potential risk. PBE proximity warning systems use colour-coded warnings, such as yellow or red alerts, to help indicate the severity of a potential collision risk and support an appropriate response.
For operations working with heavy vehicles, mobile machinery and complex site layouts, systems such as PBE’s PAS-C can provide an important additional layer of awareness.
Dash-Mounted Proximity Alert Devices for Real-Time Awareness
Carroll Technologies Group also offers PBE’s PAS-Z Proximity Alert System, a dash-mounted proximity detection device designed to warn operators when they are approaching another vehicle, person or potential obstacle.
The PAS-Z provides audio and visual warnings to help drivers respond to hazards in real time. It can also support real-time video surveillance, helping operators maintain better awareness in environments where their direct line of sight may be compromised.
Like the PAS-C, the PAS-Z can support geo-fencing technology, helping operators manage risks around pre-defined hazards such as bottlenecks, restricted access points, hazardous travel ways and high-risk work areas.
For industrial sites where equipment movements are frequent and visibility is often limited, dash-mounted proximity alert devices can help drivers make safer decisions and reduce the risk of collision.
ELOKON Forklift Proximity Detection for Warehouses, Manufacturing and Industrial Sites
For environments where forklifts and pedestrians work closely together, Carroll Technologies Group also supplies ELOKON proximity detection solutions.
ELOKON’s ELOshield system is designed to enhance safety around forklifts, pedestrians and other vehicles. It is particularly useful in warehouses, manufacturing facilities, logistics operations, loading areas, maintenance shops and other industrial environments where forklift traffic is frequent.
ELOshield uses Ultra-Wideband technology to detect the position of forklifts, pedestrians and other equipped vehicles. Modules can be installed on forklifts, while personal modules can be worn by pedestrians working in the same area.
When a pedestrian moves too close to a forklift, the system can alert both the driver and the pedestrian. Drivers can receive visual and acoustic warnings, while pedestrians can receive acoustic and vibration alerts. Where configured, the forklift can also be slowed automatically to help reduce the risk of an incident.
The system supports programmable detection zones, allowing warnings and responses to be adapted to the needs of each site. This can include vehicle slow-downs, stop functions, driver alerts and pedestrian warnings.
ELOshield can also detect other forklifts, helping to reduce the risk of vehicle-to-vehicle collisions in high-traffic areas. Fixed-position modules can be installed in key locations to manage vehicle speeds, support controlled movement and provide additional warnings in areas where risk is higher.
Choosing the Right Proximity Detection System for Your Site
The right proximity alert system will depend on the type of equipment being used, the layout of the site, the movement of pedestrians, the level of vehicle traffic and the specific hazards that need to be controlled.
For heavy equipment and mobile machinery, PBE’s PAS-C and PAS-Z systems can support proximity warnings, geo-fencing and improved operator awareness.
For forklift-heavy environments, ELOKON’s ELOshield system can help manage risks between forklifts, pedestrians and other vehicles, particularly in indoor and high-traffic industrial settings.
Carroll Technologies Group can help operators choose the most suitable proximity detection solution for their working environment, whether the priority is vehicle-to-person detection, vehicle-to-vehicle collision avoidance, pedestrian warning, geo-fencing or forklift speed management.

From fires and dust explosions to gas emissions and windblasts, history tells us that the majority of mining accidents are ventilation-related.
Just seconds of breathing contaminated air such as carbon monoxide can have severe consequences.
While ventilation has no direct contribution to a mine’s production, failing to properly control airflow within an underground mining site can also lead to increased accidents and damage the health of workers, as well as decrease productivity and efficiency.
It’s no wonder then that ventilation is among the most important aspects of underground mining.
In order to ensure miners are safe in their workplace, effective equipment must be provided and correctly maintained.
The Different Types of Mining Ventilation Systems
To comply with this heavily regulated aspect of mine safety, suitable airways must be in place to allow clean air to come in and ensure contaminated air is filtered out.
There are several approaches mine operators can take to achieve a safe airflow and underground ventilation.
Ventilation on Demand (VOD)
Ventilation on demand for underground mines (VOD) has become an increasingly popular option.
This type of mining ventilation system uses sensors to detect where people and machinery are present and directs clean air to flow through these areas only, instead of the entire site.
Flow Through Ventilation
This variety is often the main and most natural option for underground mine ventilation.
The flow through ventilation methods sees air enter the mine from the surface via a shaft, which is then distributed by venturi tubes and controlled by ventilation fans and other types of regulators.
Ventilation Mining Curtains
Ventilation mining curtains can also be used to manage a site’s air requirements.
This approach works by channeling air to different areas and trapping any potential contaminants. Mining curtains are often the only practical option for underground use.
Carroll Technologies Group is a leading supplier of mining safety appliances throughout North America.
We supply a range of ventilation curtains from Bluefield Manufacturing and can customize them by size, grommet type, spacing and material as per customer request.
Bluefield’s catalog of mining ventilation curtains are designed to be tear-resistant, with the ability to withstand a wide range of temperatures.
They are lightweight, made from either a woven or double laminate polyethylene material, and customers can choose from varying degrees of transparency to allow for high visibility.

It’s no secret that mine work can be dangerous work, and that’s why safety should be at the heart of every mining operation.
Whilst each mine may take a different approach – initiatives, ongoing training, or special programmes, for example, the wellbeing culture of a mine can be vastly improved by investment in the latest portable gas detection technology.
Companies that take advantage of developments in safety equipment send a clear message to their staff: We are committed to keeping you safe.
Monitoring the underground atmosphere is one such commitment. Without warning, harmful vapours can be inadvertently released within a mine.
Methane, for example, becomes highly flammable and even explosive at atmospheric levels as low as 5%-15%, while carbon monoxide levels as low as 0.1% can cause fatality within a few minutes.
In as little as 30 seconds of oxygen deprivation, a miner can lose consciousness, making the investment in quality handheld carbon monoxide detectors absolutely crucial.
According to leading North American mining industry supplier Carroll Technologies:
“It is vital for mine workers to be able to detect changes in their atmosphere immediately.
“Portable gas 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.”
One device supplied by Carroll Technologies is the Mine Safety Appliances (MSA) Altair 4X Gas Detector, a fully portable device representing the very highest calibre in mining handheld gas detectors.
The Altair can be carried by miners as their own personal gas detector, alerting the user to the presence of combustibles, toxins and anaerobic environments within 15 seconds of detection.
Real-Time Safety Monitoring
With patented MotionAlert technology as standard, the portable device activates an alert when no movement is detected from an active user for 30 seconds or longer, should they be injured or unconscious.
Users are also able to manually activate the InstantAlert alarm, which utilises the device’s warning system to alert others of hazards in the 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 means it can be easily operated even if the user is wearing gloves.
Plus, when paired with the MSA ALTAIR Connect app via a Bluetooth wireless connection, the Altair can also provide real-time incident awareness to team members, supervisors, and safety managers.
Event notifications can even be sent via text message with the Altair Connect app.
Handheld Gas Detector Solutions at Carroll Technologies
Carroll Technologies, which has been a leader in the North American mining industry for more than 30 years, is a factory-authorized warranty mining repair center.
They provide after-sale repair services for handheld gas detectors and a broad range of other essential mining safety equipment to over 800 mines.
Customers can also reach out to the MinerCare 24/7 team, where highly skilled staff are on hand to provide technical support and same day delivery for products and parts required from a network of 13 distribution centres across North America.
When workers are tunnelling underground it is imperative they are able to converse with each other, especially in the case of major incident or accident, which is where underground mine radio systems come into play.
An advanced workplace communications system maximizes the efficiency and productivity of the operation. Carroll Technologies Group supplies a range of portable underground mining radio and radio systems from Kenwood and Motorola, as well as stationary leaky feeder systems.
Over 800 mines across North America put their faith in the solutions supplied to them by Carroll Technologies Group every day to keep their facilities running, supported by Carroll’s 24/7 MinerCare team.
Portable Underground Mining Radios
Kenwood supplies and manufactures both analog and NEXEDGE® digital handheld portable mine radios, designed to withstand the extreme conditions of a mine and allowing instant communication between units. Used in mining operations across the world, the ATEX-certified devices are equipped with gas, dust and mining protection.
These easily transportable radios are equipped with a long battery life, with the NEXEDGE® models also boasting GPS capacity.
Motorola likewise offers a series of two-way radio solutions known as the MOTOTRBO range, varying from simple-voice only models to feature-rich voice and data radios. They are accompanied by a wide range of accessories to optimise the performance of the device and have been put through an Accelerated Life Testing (ALT) process to ensure they can withstand up to five years of field use.
Stationary Mine Communication Systems
Should a mining facility be in need of a stationary system, a leaky feeder system can provide effective and secure communication both underground and above ground. Carroll Technologies Group supplies the PB2 112 Page Boss Phone, a stationary two-way radio which can work with traditional pager-type systems and be integrated into leaky feeder system.
A leaky feeder system is more stable than a traditional wired phone system, and can be integrated with tracking and monitoring technologies to provide a holistic solution to everyday mining communication.
In this system, a cable is stretched throughout a mine and it acts as an antenna for a number of devices to pick up a radio signal. This way radio devices do not have to stretch to communicating with each other over long distances, where this may not be possible or practical, but instead communicate with the cable. This extends the range of the devices, meaning a worker ten miles below ground can communicate with a colleague ten miles above ground using the antenna between them as a connection.
These systems can be divided into older pager systems and more modern leaky-feeder systems, both of which have their own pros and cons depending on the operation.
Underground Mining Telephones Available from Carroll Technologies
Carroll Technologies supplies a wide range of Page Boss mine phones and underground telephones, designed for use in harsh conditions. Our mining communication solutions include:
Paging telephones in mines are battery-powered, hard-wired communication units that use radio signals to send individual audio and text messages. These mine telephones connect underground personnel with surface-level operators, ensuring clear, static communication. While they have a more limited range than leaky-feeder systems, underground page phones are ideal for smaller or shallower mines where communication needs are more localized.
Leaky Feeder Systems and Integration
Leaky-feeder systems offer both wired and wireless communication throughout a mine. The leaky feeder cable, a type of coaxial cable with sections of its shielding removed, allows radio signals to “leak” in and out. Stretched across mining tunnels, it acts as an antenna that devices can connect to, greatly extending communication range.
This makes leaky feeder systems a better choice than paging-only setups for large or complex mining operations. Carroll’s minephone offerings from Pyott-Boone Electronics (PBE) can be installed as part of either system, giving mine operators the flexibility to build the ideal communication network.
Portable Underground Communications with the Sybet System
In addition to fixed underground mine phones and leaky feeder systems, Carroll Technologies also offers the Sybet portable communication system as a flexible solution for dynamic underground operations. The Sybet system is ideal for environments where personnel and equipment are frequently relocated, offering reliable portable underground communication without the need for complex infrastructure. This makes it a strong complement or alternative to traditional mining telephone systems, especially in smaller mines, development headings, or temporary work zones where installing permanent underground phones isn’t practical.
Mine Phones for All Environments
The PBE Gen 2 underground mining phone (Model 112) is a two-way radio mine phone that works with both pager and leaky feeder systems. It’s part of PBE’s advanced range, supporting proximity alerts, gas monitoring, and both text and voice communication.
Models 118 desktop mining phones are best suited for control rooms at the surface level and feature battery backups to maintain functionality during power outages.
The Model 139 Page Phone Coupler allows connection between standard page phones and external communication networks.
24/7 Support for Mine Phone Systems
All customers benefit from MinerCare 24/7™, our around-the-clock support line. Whether you’re using underground mine phones, mining phone systems, or integrating a full underground communication network, our team can talk you through issues, assist with network design, and action same-day part deliveries.
Maintaining a proper ventilation system is vital for worker safety, but it’s still important to have emergency breathing apparatus at the ready for crisis situations. There are various devices available to ensure the safety of miners in irrespirable atmospheres, each with their own unique practicalities, meaning mine operators can always be safe in the knowledge that their workers have the most comprehensive protections available.
Plenty of these devices are available through Carroll Technologies Group, a leading supplier of mining apparatus and equipment. Trusted by over 800 facilities across North America, Carroll Technologies Group’s 24/7 MinerCare support team is always on hand to provide support and guidance to those in need. This includes coverage for a full range of self-contained self-rescuers (SCSRs), one of the most important devices a miner carries with them day to day.
“MSHA, the regulating body for the mining community, mandates that anyone who is underground has to have an SCSR,” said Carroll Technologies Group’s Josh Johnson.
Why is an SCSR an important piece of mining breathing equipment?
Accidents such as a fire or an explosion can compromise air breathability and leave workers without rescue for some time. They may even be required to make their own way to safety. This makes an SCSR a vital part of the miner’s arsenal.
These easily portable devices provide personal respiratory protection to each individual miner, and should be carried at all times as a safety precaution. The typical SCSR blocks air flow from the nose and the miner instead breathes through the mouthpiece of the device, which oxidises air pollutants and converts them into a breathable format.
This can sometimes feel uncomfortable as the air provided by the SCSR can become very hot and dry, but it’s important no miner sneaks a breath of cool air from around the device – a carbon monoxide concentration as low as 0.5% can cause collapse, unconsciousness, and death in just a few minutes.
Among the market-leading SCSRs supplied by Carroll Technologies Group is the W65 Self-Rescuer Respirator from Mine Safety Appliances (MSA).
This particular device is intended to protect specifically against carbon monoxide poisoning, and weighs only 2.2lbs. Protected inside a rugged stainless steel case, the W65 as a positive hermetic seal and has a total life of 15 years, with an in-service life of ten years. It’s important to note that the W65 is a one-use only device, and should not be used in atmospheres containing less than 19.5% oxygen or which have become polluted by toxic gases and vapours other than carbon monoxide.
Carroll Technologies Group also supplies two SCSRs from Ocenco, the M-20 and the EBA 6.5.
The M-20 is a belt-borne device which comes in 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.
The underground mine self rescuer provides short-term and long-term protection
The EBA 6.5 is a little different to the other two devices. These devices will be stored in bulk in a refuge centre of a mine, which workers can make their way to in the event of a crisis with the initial help of a W65 or M-20. They can then transfer to the larger, closed-circuit apparatus of the EBA 6.5. This device uses compressed oxygen rather than an oxidisation process, making it more comfortable to wear and with a longer window of active use.
“If there was a situation where a mine rescue was going on, the EBA 6.5 would allow up to 90 minutes of operation time straight,” said Johnson. “The device has oxygen in a resting type of situation, so if someone were actually stuck in a mine, if there was an explosion and they couldn’t get out, they could regulate that oxygen on and off as they needed it. They could make it work for somewhere up to 8 hours if they needed to.”
The EBA 6.5 can also be refurbished and upgraded where other devices cannot, with a clear case which allows the user to monitor their oxygen supply.
The US Mine Safety and Health Administration (MSHA) reported 27 mining industry deaths across the country in 2018.
This was the second lowest annual figure ever recorded, but there is still more mining operators can do by employing a comprehensive range of mining safety appliances and systems.
Mine safety systems such as proximity alert apparatuses are vital to avoid haulage accidents
Alongside investing in sophisticated personnel awareness it’s important operators kit out their mining sites with proximity alert systems.
Proximity alert devices can prevent haulage-related injuries and fatalities by minimizing the risk of collision.
Typically an alarm is triggered when two tagged elements pass too close by each other – eg, a person and a moving vehicle – warning workers so that they may remedy the situation as appropriate.
Carroll Technologies Group supplies PBE’s PAS-C Proximity Alert System, which utilizes electromagnetic sensors and GPS tracking to detect vehicles, obstacles, and personnel.
This allows collisions to be predicted and avoided, and help is always on hand from Carroll’s 24/7 MinerCare support center. Just a phone call away, MinerCare are committed to providing Carroll Technologies customers with the expert product support they need to ensure their facility runs safely and smoothly.
Mining safety appliances are particularly important when it comes to a breathable air supply
Worker safety can also be put at risk as a result of a compromised oxygen supply. The atmosphere in a mine must be regularly monitored for the presence of flammable methane gases and carbon monoxide.
Personnel can be alerted to any airborne contaminants via a multi-gas detector. These appliances can be fixed in high-risk areas to provide constant monitoring or portable to permit a miner to test the atmosphere manually, often before entering a confined space.
One such device available from Carroll Technologies Group is the MSA Altair 4X. This device is triggered by both methane and carbon monoxide, and lets workers know that the air around them is no longer safe to breathe prompting them to don their self-contained self-rescuers (SCSRs).
An SCSR is an easily portable device which a miner may carry on their person as a safety precaution – MSHA actually mandates that all workers in underground mines must have an SCSR with them at all times.
Carroll Technologies Group offers devices such as the Mine Safety Appliances (MSA) W65 Self-Rescuer Respirator and Ocenco M-20, both belt-worn devices which miners can quickly strap on in the event of an emergency to protect their lungs from dangerous gases such as carbon monoxide as they make their way to safety.
For more long-term search and rescue operations, Carroll customers can also access the Ocenco EBA 6.5. This is a larger, full-body piece of equipment providing a supply of oxygen for a much longer period of time. These can be stored in bulk in refuse centers throughout a mine. Workers who may be stuck underground for some time can then await rescue using the EBA 6.5 to keep themselves safe.
Unexpected, harmful vapors can be inadvertently released within a mine without warning, which is why miners need to always be prepared for a potential gas leak or drop in oxygen levels with atmospheric monitoring 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.
Miners can protect themselves against the atmospheric hazards in their working environment by using both hand-held and fixed underground atmospheric monitoring devices for confined spaces.
These include multi-gas detectors, anemometers and diesel particulate monitors (DPMs), all of which are supplied by Carroll Technologies Group.
Carroll has led the North American mining industry for over 30 years and today provides over 800 mines with a broad range of safety equipment. Its customers can also reach out to its MinerCare 24/7™ team, who are continually on hand to offer technical support.
Hand-Held Underground Atmospheric Monitoring Equipment and Air Monitoring Devices
One easily portable confined space air monitoring device supplied by Carroll represents the very highest caliber of multi-gas detection technology – the Mine Safety Appliances (MSA) Altair 4X Detector.
The Altair can be carried day-to-day by miners and will alert the user to the presence of combustibles, toxins and anaerobic environments within 15 seconds of detection.
The detector, which comes with patented MotionAlert™ technology as standard, will activate an alert when no movement is detected from an active 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 warn others of hazards in the near vicinity.
The ventilation of a mine system also needs to be monitored and managed regularly, and a tool such as an anemometer is vital for doing so. These small, portable devices use wind velocity to measure the volume of air entering and exiting the mine shaft, ensuring there is enough airflow to prevent the accumulation of dangerous gases.
This not only keeps workers safe but maximizes a mine’s efficiency by providing a comprehensive overview of the ventilation system.
Using an anemometer is one of the easiest ways to test air quality in a mine, and can be used to select appropriate ventilation equipment as well as ensure worker safety.
This technology can be used for both quick ad-hoc checks and long-term monitoring of airspaces, requiring minimal technical understanding to operate.
Carroll supplies the ST-1000 Vane Anemometers, portable models ideal for carrying by hand to monitor air quality between mining sites.
Underground Atmospheric Monitoring Devices Sensitive to Diesel
With diesel engines commonplace in the mining workplace, it is vital that workers are conscious of the diesel levels present in their atmosphere.
To this end Carroll stocks the Flir Airtec DPM, which is a lightweight, portable device that can be strapped to a miner’s belt, attached to a vehicle or mounted on a wall in a high-risk area, displaying real-time elemental carbon levels on an LCD screen.
The Airtec system allows miners to modify vehicle use, their positioning or the ventilation system should diesel levels in the environment become too high. It also allows users to monitor the underground site for ongoing diesel overexposure.
With regulations, site conditions, workforce needs and equipment risks continually evolving, operators must be able to demonstrate that workers are properly trained, that hazards are being identified and controlled, and that safety programs are kept up to date with current Mine Safety and Health Administration (MSHA) expectations.
Through its partnership with MSHA Safety Services, Carroll can now connect customers with specialist mine safety professionals who understand the practical challenges of maintaining compliance in active mining environments. From workforce training and site audits to industrial hygiene support and project safety staffing, the partnership provides mine operators with a reliable path to the expertise, equipment, and ongoing support needed to strengthen safety performance.

Supporting safer operations in a changing regulatory environment
Recent developments in mine safety have placed renewed focus on proactive compliance planning, written safety programs, industrial hygiene and workforce training. Mine operators are expected to maintain clear systems for identifying hazards, reducing risk and keeping employees informed of safe working practices.
One key area of focus is surface mobile equipment. Mine operators are now required to develop and maintain written safety programs for surface mobile equipment at surface mines and surface areas of underground mines. These programs are intended to help reduce accidents, injuries and fatalities associated with mobile equipment by formalizing the processes for identifying, reviewing and controlling hazards.
Respirable crystalline silica exposure also remains an important compliance and worker health issue. Mines need to maintain effective dust control, respiratory protection, monitoring and industrial hygiene practices in line with applicable standards.
By working with MSHA Safety Services, Carroll customers can access guidance to support practical compliance, including facility audits, safety recommendations, accident investigation support, hazard communication improvements, and preparation for evolving mine health and safety requirements.
Product training for critical mine safety equipment
In addition to compliance and workforce training, Carroll Technologies Group provides training on major safety products within its portfolio. This includes equipment and systems from leading manufacturers across Carroll’s network of more than 80 partners.
Training can cover areas such as:
MSHA electrical safety requirements
