Keeping Underground Mining Safe with OnGuard!

High-efficiency air filtration system with durable black filters and white PVC piping, designed for improved indoor air quality and ventilation in industrial and commercial facilities.

In underground activities, especially tunnelling and mining, dust exposure and poor air quality are critical health hazards. Limited ventilation, restricted air circulation, and the accumulation of carbon dioxide can quickly create unsafe working conditions for machine operators and crew members. To address these challenges, BreatheSafe designs and installs advanced filtration and pressurisation systems that provide operators with a clean, safe, and comfortable environment even in the harshest underground settings.

The Challenge of Underground Air Quality

Unlike open-air environments, underground worksites have very limited natural ventilation. Dust generated from drilling, cutting, and vehicle movement can remain suspended in the air for long periods.

At the same time, carbon dioxide produced by diesel engines, blasting activities, or human respiration can accumulate within enclosed spaces.

These conditions can cause a drop in oxygen concentration, increase operator fatigue, reduce visibility, and pose long-term respiratory risks. Maintaining air quality in such an environment requires a continuous and intelligent approach.

How OnGuard Keeps Operators Protected

To ensure the safety of operators, BreatheSafe’s OnGuard air quality manager continuously monitors and manages air quality inside control rooms, break rooms, medical rooms, and offices.

The system automatically detects changes in pressure, carbon dioxide (CO₂), and dust levels, then reacts intelligently to any changes in air quality. It maintains positive pressure inside the room to prevent contaminated air from entering and logs air quality data for compliance and performance tracking.

This fully automated process allows operators to focus on their tasks while OnGuard maintains a stable and safe working environment without the need for manual adjustment.

Custom Solutions for Demanding Conditions

Not only the RoomSafe system, but BreatheSafe also provides tailored solutions for underground machines, as well as electrical enclosures. Each system is custom-designed to meet specific site conditions or equipment requirements, ensuring optimal performance, safety, and reliability.

Whether it is protecting operators underground, safeguarding electrical components from dust and heat, or maintaining clean air in break rooms, BreatheSafe delivers integrated air quality solutions that enhance both safety and operational efficiency across all environments.

Operator Cabins – BreatheSafe System

What it does:
BreatheSafe system filters and pressurises air in mobile machinery like excavators, dozers, trucks, and drills.

Key features:

  • HEPA H14 filtration removes 99.995% of harmful dust (carbon filter optional for gas removal)

  • HEPA Panel Return Air Filter scrubs and filters the internal air
  • Positive pressure keeps contaminants out

  • Real-time monitoring of CO₂, PM2.5, airflow, and cabin pressure

Why it matters:
It protects machine operators at the source of exposure and helps your site meet safety standards for air quality.

Electrical Enclosures – VoltAire System

What it does:
VoltAire protects sensitive electronics inside the enclosure by preventing dust ingress and heat build-up. This improves the reliability and longevity of critical electrical components.

Key features:

  • EPA E11 pressurisers filter incoming air.

  • Positive pressure prevents contaminated air from entering.

  • Automatically manages pressure and flushes out hot air when electronics begin to overheat.

Why it matters:
Electrical components are highly sensitive to heat and airborne contaminants. Reducing maintenance costs and extending equipment lifespan.

The new ISO 23875 standard places a greater emphasis on the air quality inside the operator cabin than has been previously addressed.

BreatheSafe has always focused on air quality

ISO 23875 for the Mining Industry

BreatheSafe systems meet and exceed this standard with our new INPRESS TS.

There are 5 performance requirements in ISO 23875

  1. Higher filter efficiency requirements
  2. Defined maximum CO2 level
  3. Recirculation and fresh air system requirements
  4. Established cab pressurisation levels
  5. Real-time operator cab monitoring

INPRESS

INPRESS Auto Pressure Control

The INPRESS TS is the latest touchscreen monitor controller of the BreatheSafe system. It provides automatic control over the air filtration system and utilises a simple interface for a user-friendly experience.

ISO23875 Performance Requirements

The BreatheSafe High Pressure HEPA Filtration system meets and exceeds ISO23875 requirements

Filter Efficiency Requirements

BreatheSafe uses HEPA H14 filters at 99.99% efficient of particles 0.3 microns in size. This is more efficient and safe than the standard of H13.

Maximum CO2 Levels

Using maximums outlined in the standard, the TS alerts the operator when CO2 levels reach and pass acceptable levels, and increases airflow to minimise CO2.

Recirculation and Fresh Air

BreatheSafe systems are integrated into the OEM aircon system. Both the fresh and recirculated air are filtered through HEPA filters for optimal protection.

Pressurisation Levels

The TS automatically controls pressure levels to remain at a pre-set pressure by adjusting blower speed of the pressurisation unit.

Real Time Monitoring

The TS is equipped with live charts, auto-recording of events, and auto data logging to ensure prolonged safety.

Features

Automatic Pressure Monitor

The INPRESS TS (TLUCPMCO2) automatically controls the blower speeds to maintain preset cabin pressure. It does this by monitoring the pressure through its built-in pressure transducer.

Industry minimum standard is between 20 and 50 Pa from new. Our systems are preset to remain at 50 Pa but can be changed through system settings.

The TLUCPMCO2 measures the pressure inside and outside the clean air compartment and calculates the error based on the pressure setpoint. An algorithm applies these values, and the controller calculates a proportional output that adjusts the speed of the pressuriser motors.

Automatic Alarms

The BreatheSafe TLUCPMCO2 automatically sounds alarms at pressure drops, alerting the operator to the potential of hazardous air.

Optionally, the unit can distinguish if a door or window is not sealed correctly and alert the operator. At the same time as this alert is sounding, the blower power will increase to keep the operator as safe as possible.

CO2 Sensor option (ISO 23875)

With the option to add TLUCPMCO2 BreatheSafe CO2 sensors, operators will be alerted when unsafe air quality conditions are present by providing real-time CO2 data and audible/visual alerts.

Automatic Data Logging

The BreatheSafe INPRESS automatically records and stores recorded data, depending on sampling requirements this can be up to 12 months.

The TLUCPMCO2 controller is designed to start data logging as soon as it is powered up. Data samples time, date, motor capacity, and current pressure readings. This is additional to standard alarm logging, which occurs at every alarm instance.

Service Test Mode
