Carroll Technologies makes available competitive pay and a comprehensive benefits package, which included a 401(K) plan, vision and dental insurance, life insurance, short and long-term disability coverage, company holidays and other miscellaneous benefits. Also note that Carroll Technologies provides 12 days of annual vacation.
With over 30 years of experience supplying safety and environmental monitoring devices, Carroll Technologies stocks and distributes Zefon products across the U.S. mining industry. Carroll Technologies president, Allen Haywood, emphasizes the reliability of Zefon’s products: “Zefon is a great company with a product that has been reliably tested and proven. We have been distributing for them for decades, and we are an authorized repair and calibration facility for that product.”
Zefon Pumps for Environmental Monitoring
Pumps are central to the air sampling and analysis process. In environmental monitoring, Zefon offers a range of advanced air sampling pumps suited for various applications, including indoor air quality (IAQ) analysis, personal abatement, and industrial hygiene. Paired with filters or sampling cassettes, Zefon’s pumps are capable of detecting exposure to harmful substances like asbestos, respirable dust, mold spores, silica, beryllium, and hazardous particulates.
Zefon’s latest innovations include the Zefon Bio-Pump Plus, a state-of-the-art, portable, battery-powered IAQ pump designed specifically for use with Air-O-Cell and Via-Cell cassettes. The Bio-Pump Plus is lightweight and user-friendly, featuring programmable sample times and a real-time display. Its long-lasting NiMH battery supports up to eight hours of continuous use or 100 five-minute samples, making it highly efficient for fieldwork. This model also offers quiet operation and provides visual and audible indicators to signal when a sample collection is complete.
For environments that demand higher precision, such as mining or hazardous industrial settings, the Zefon Escort ELF sampling pump is an ideal solution. Built with intrinsic safety features, this pump provides excellent laminar flow control with temperature and pressure compensation, ensuring reliable accuracy in challenging environments, including underground locations.
Diverse Pump Options for Varied Applications
Zefon’s Z-Lite IAQ pump series is another addition to its lineup, designed to handle IAQ sampling with ease. These pumps are capable of operating on both DC and AC power, providing flexibility in the field. Z-Lite pumps are particularly well-suited for applications that require low backpressure sampling devices, such as spore traps. With their versatility, they meet the demanding needs of environmental monitoring and industrial hygiene professionals.
Gas Detection and Additional Services
In addition to its air sampling pumps, Zefon also produces gas detector tubes. These tubes detect the presence of gases by changing color when they react with a specific airborne compound. Zefon’s gas detection technology is a simple, safe, and cost-effective method for identifying flammable or toxic gases, pollutants, and vapors. This rapid detection capability eliminates the need for lab-based analysis, making it invaluable for on-site inspections.
Carroll Technologies supports Zefon customers through its MinerCare 24/7 support service, offering certified repair services for Zefon products, alongside other environmental monitoring devices. This service provides continuous technical support, rapid response to mining emergencies, and an extensive stock of spare parts.
The rule aims to protect miners from severe health issues such as silicosis, lung cancer, and chronic bronchitis, which are caused by prolonged exposure to silica dust in mining environments.
Coal mines must be in compliance with the new rule by April 2025, while MNM mines have until April 2026. This staggered timeline provides operators with some time to implement the necessary controls and procedures to meet the new requirements. However, given the complexity of the rule, operators are urged to begin preparations well in advance to avoid penalties and ensure the safety of their workforce.
The Significance of the New Silica Dust Rule
The new rule, outlined under 30 CFR Part 60, mandates that mining operations limit workers’ exposure to RCS to no more than 50 micrograms per cubic meter of air, calculated as an 8-hour time-weighted average. This represents a significant reduction from previous limits and reflects the growing understanding of the dangers associated with silica dust inhalation.
Respirable crystalline silica, often found in dust created during mining activities like drilling and blasting, is particularly hazardous due to its ability to penetrate deep into the lungs. Long-term exposure can result in irreversible diseases, many of which can be fatal. This rule is designed to prevent these diseases by drastically lowering allowable exposure levels.
What Mine Operators Need to Know
Under the new rule, mine operators must adopt engineering controls to limit dust exposure, including ventilation systems, water sprays, and enclosed cabs with air filtration systems. MSHA makes it clear that relying solely on administrative controls, such as rotating workers to limit their exposure, is not acceptable. Instead, operators must focus on preventing the dust from becoming airborne in the first place.
Additionally, regular dust sampling and monitoring will be required to ensure that exposure levels remain below the permissible threshold. If monitoring shows that levels exceed the limit, operators must take immediate corrective action. While respirators may be used in specific, limited cases (such as during maintenance), they cannot serve as a permanent solution. Mine operators are required to implement more robust and permanent controls to bring dust levels into compliance.
Medical Surveillance Requirements
A key component of the new silica dust rule is the medical surveillance program. This program will now extend to miners in the MNM sector, in addition to coal miners who are already covered by similar protections. Under this program, mine operators must offer periodic health examinations to miners, including chest X-rays and lung function tests, at no cost to the workers. These exams are crucial for detecting early signs of silica-related diseases.
For newly hired miners, these examinations will be mandatory, while experienced miners will have the option to participate voluntarily. However, MSHA encourages all miners to take part in the program to monitor their health and catch any issues before they become severe. Operators are responsible for ensuring these exams are conducted and for maintaining records of the results.
Carroll Technologies: A Partner in Compliance
As the mining industry adapts to these stringent new requirements, Carroll Technologies offers a range of solutions to help operators remain compliant with MSHA’s silica dust rule. Carroll provides advanced equipment, such as the Zefon Escort ELF Dust Pump, which is designed for accurate air sampling in mine environments. The Escort ELF Dust Pump features a laminar flow sensor for precise flow control, ensuring reliable sampling even under challenging conditions. The pump also includes features like a flow/fault indicator and a low-battery alert to make dust sampling as seamless as possible.
Carroll Technologies also supplies coal dust sampling cassettes, tubing assemblies, and calibration devices such as the DigiCal Primary Flow Calibrator, which ensures that personal and environmental air pumps are accurately calibrated. These tools are vital for keeping your operation in line with the latest MSHA requirements. With Carroll’s help, operators can implement proper dust control measures and maintain compliance through continuous monitoring.
