Introducing CabSafe

Your Road to ISO 23875 Compliance in Mining Vehicle Air

Introducing CabSafe

CabSafe – Revolutionizing Air Quality Management for Mining Vehicles

Introduction: In recent years, the spotlight on air quality within the cabins of industrial vehicles has intensified, culminating in a groundbreaking standard – ISO 23875. For mining vehicles in Australia, compliance with this standard is now not just encouraged but required.

Challenges of Non-Compliance: Non-compliance comes with its challenges, prompting the exploration of solutions such as air filtration systems that maintain a cabin’s air at a slight over-pressure, preventing the infiltration of contaminated air. However, installing such systems can be costly, making it essential to pinpoint cabins that truly require these measures.

Key Questions and Complexities: The burning questions arise: How do you identify at-risk cabins? How can you detect and resolve instances of non-compliance? And once additional filtration equipment is in place, how do you ensure ongoing compliance? This becomes even more complex when dealing with a sizable fleet of 300 vehicles.

Enter CabSafe – The Game-Changer: Enter CabSafe, a game-changer in the realm of air quality management. This easy-to-deploy module, requiring only 10-30VDC to operate, can be installed effortlessly in minutes. Even offline, CabSafe diligently keeps logs, which can seamlessly sync to a mobile device in areas lacking cellular coverage.

Magic in Data Sets: The real magic happens in CabSafe’s recorded data sets. These valuable insights can be harnessed to determine whether proactive measures are needed or if the cabin is comfortably within safe limits. With CabSafe, managing compliance with ISO 23875 becomes efficient and economical, ensuring your drivers’ safety and well-being across expansive fleets

CabSafe as the Beacon: In the world of mining vehicles, CabSafe emerges as the beacon guiding you towards ISO 23875 compliance, transforming the complex task of air quality management into a streamlined and cost-effective process. It’s time to safeguard your fleet, drivers, and compliance efforts with CabSafe.

Managing Dust for Enhanced Electronics Reliability in Mining Operations

Dust and MTBF: Enhancing Electronics Reliability

In the realm of electronics, the presence of dust within electrical cabinets poses a multifaceted challenge. While dust may lead to shorts, depending on its composition, it also acts as an insulating layer, hindering proper cooling of electrical components. As we understand, the Mean Time Between Failure (MTBF) exhibits a strong correlation with the operating temperatures of electronics, characterized by an exponential relationship. Thus, ensuring dust-free environments that facilitate adequate cooling significantly bolsters the reliability of electronic components. This realization has prompted mining companies to adopt stringent cleaning procedures for critical electronics cabinets.

Cleaning Procedures and RCS: A Safety Concern

Pressurized air stands as the primary tool for periodically clearing dust from electrical cabinets. However, a substantial portion of this dust comprises Respirable Crystalline Silica (RCS), presenting a significant safety hazard for individuals conducting the cleaning. Exposure to RCS can contribute to severe ailments such as silicosis and lung cancer. Alarmingly, in 2017, the Queensland Mines Inspectorate reported that around 50% of all respirable dust and RCS exceedances observed in surface coal mines stemmed directly from compressed air usage during maintenance activities. Notably, a third of these exceedances specifically related to blowing out high voltage cabinets in electric drive trucks or motor-generator sets in dragline houses.

Prevention Over Remediation

Given the hazardous nature of cleaning operations, it becomes imperative to prevent dust intrusion into electrical cabinets altogether. This approach not only minimizes the need for risky cleaning procedures but also promotes a safer work environment. To support this preventive stance, CabSafe has collaborated with a mine operator in Australia to install CabSafe units inside the main electrical cabinets of Komatsu mining trucks. These installations serve as the baseline for quantifying the effectiveness of future improvements.

CabSafe Installation and Data Analytics

CabSafe operates as a fully self-contained air-analytics lab, requiring either 10-30VDC or a USB battery bank for operation. Data retrieval occurs via LTE-M or through a mobile phone, facilitating seamless offloading to the analytics portal. Its self-contained design allows for flexible deployment, enabling detailed air-quality assessments within driver cabins or electrical cabinets.

Measurement Insights

CabSafe’s built-in accelerometer enables the distinction between the truck’s stationary and driving states. Each graph provides averages and standard deviations for both datasets, highlighting notable differences in CO2 readings and particle concentrations between stationary and mobile states. Baseline readings underscore substantial room for improvement. Following enhancements to the air-cooling systems within these cabinets, we anticipate quantifiable improvements, which will be documented in future measurement campaigns.

Stay tuned for updates on our ongoing efforts to optimize the cooling of this Komatsu truck electrical cabinet!
