Dust Monitoring Systems for DPM and Crystalline Silica

Exposure to diesel particulate and crystalline silica must be assessed where risks are present. Monitoring provides the evidence required to demonstrate compliance and manage workplace health risks effectively.

For WA projects to ensure employee safety and regulatory compliance, exposure to diesel particulate matter and crystalline silica must be understood and addressed. ENVSS monitoring programs provide the evidence required to demonstrate compliance and manage health risks effectively.

What Are Diesel Particulates?

Diesel particulate matter (DPM) is a complex mixture of particles and gases produced when combusting diesel fuel. It typically includes carbon based particles, hydrocarbons, metals and other byproducts.
DPM is incredibly small and particles can remain airborne for extended periods. On site, that increases the risk of inhalation and associated health and compliance concerns.

What Is Crystalline Silica?

Crystalline silica is a naturally occurring mineral used in man made sands, stones, concrete and bricks. When these materials are altered in any way, fine silica particles can become suspended.
The most significant risk comes from respirable crystalline silica (RCS). These particles are small enough to lodge deep in the lungs and, as they are not always visible, can cause damage without obvious red flags in the work environment.

Why is Monitoring Necessary?

DPM

In industries where diesel powered machinery is commonly operated in confined or poorly ventilated space, DPM exposure is a common issue. Excess exposure often leads to respiratory irritation and reduced lung function, but in extreme cases can trigger cardiovascular strain and an increased cancer risk.
A robust DPM monitoring plan is essential to ensure employee safety and project compliance for many mining, transport and construction operators.

Crystalline Silica

As mentioned above, RCS exposure is most common where fine particles are suspended via alterations to concrete, stone and other products. Associated health effects include silicosis, COPD and lung cancer.
Again, a comprehensive monitoring program is critical in protecting employees and ensuring projects remain within acceptable exposure thresholds.

When Is Monitoring Required?

DPM

In Perth and WA, diesel particulate monitoring is required when exhaust is present and exposure levels cannot be determined otherwise. Common instances include the introduction of new diesel powered equipment or worker reported symptoms.

DPM monitoring might also be undertaken as a part of wider dust monitoring or hygiene program.

Crystalline Silica

Monitoring is necessary when work activities generate silica dust and exposure levels cannot be confirmed. This could be following the cutting or grinding of engineered stone or after demolition works.
Monitoring may also be required following worker complaints or with the introduction of new processes. Like DPM, RCS assessments can be integrated into wider dust monitoring and OH programs.

How ENVSS Conducts Air Particulate Monitoring

At ENVSS, dust monitoring is conducted using respected methods that measure total carbon and/or RCS. Our process is as follows:

  • Personal Monitoring: We provide your staff with sampling equipment to wear during their normal duties. This assesses their individual exposure over a shift.

  • Static Area Monitoring: Sampling pumps are placed in fixed positions to assess general exposure levels in work areas or enclosed environments.

  • Analysis: Filters are sent to NATA-accredited laboratories to be analysed against internationally recognised methods (e.g., NIOSH 5040).

  • Reporting: Results are interpreted in line with occupational exposure limits and we provide practical recommendations to reduce risks. This includes assessing existing controls on site, such as exhaust filtration systems and ventilation.

ENVSS units are constructed at our Perth facility and tailored to suit your site. They can be fitted with an ethernet, GSM, radio or satellite communication option.

Once operational, the equipment is monitored on a daily basis, with maintenance and calibration carried out either monthly or as required.

Supporting Compliance and Risk Management

Air particulate monitoring forms a core part of a broader occupational hygiene strategy.
During daily operations, monitoring creates a safer environment for employees/occupants and supports site managers in making informed decisions about procedure design. When it comes to compliance, it proves your conformity with exposure standards and demonstrates a proactive approach to risk management.
By incorporating DPM and RCS monitoring into routine practices, site managers can reduce uncertainty and ensure their operation maintains acceptable exposure levels.
