Diesel Particulate Monitors

Diesel Particulate Monitoring

Overview

Diesel Fume Exposure Monitoring – Requirements For WA Mining Companies

The Department of Mines wants to see proper monitoring plans in place using equipment specifically suited for diesel particulate measurements (DPM). The protection of underground workers is paramount as the health effects of long term DPM exposure can be serious.

All underground mines using diesel vehicles must:

  • 1.) Conduct personal diesel fume monitoring.
  • 2.) Conduct background diesel fume monitoring.
  • 3.) Conduct on‐vehicle diesel fume monitoring (if needed).

Personal Diesel Particulate Monitors

TSI real-time series of personal aerosol monitors are rugged, lightweight, belt mounted laser photometers, weighing as little as 455g. They are compact and quiet, minimizing interference and worker discomfort. They incorporate TSI’s smart battery management system, which includes long-running NiMH or alkaline battery packs and provides precise run time information in minutes remaining. The monitor’s easy-to-read display shows your data in both real-time aerosol mass concentration and 8-hour time-weighted average (TWA). With its convenient data logging and long battery life, the monitor is also ideal for extended sampling. The units are also intrinsically safe (CSA).

Activating the data logging feature allows the company or wearer to record high resolution DPM exposure data taken over one or more work shifts. This data can
later be downloaded to show the time, date, levels of exposure and the duration of exposure to diesel particulates. This is highly valuable and sought after information that helps companies improve processes and safety for their workers.

None of the above can be achieved using sampling pumps and filter cassettes

Portable and Fixed Diesel Particulate Monitors – Background Monitoring

The TSI DPM Aerosol Monitors are battery-operated, data-logging, light-scattering laser photometers that give you real-time aerosol mass readings. They use a sheath air system that isolates the aerosol in the optics chamber to keep the optics clean for improved reliability and low maintenance. Each unit is specifically calibrated for Diesel Particulate Monitoring.

These monitors provide 24 hour continuous monitoring & data logging of DPM levels helping companies identify hot spots, such as improperly tuned diesel vehicles. The collection of instant real-time data and the use of audible / visual alarms, allows people to be properly informed and take action if need be. Thus providing better safety for your workers.

Data logging allows the user to capture valuable data such as the time, date, levels of exposure and the duration of exposure to diesel particulates. Analysing the data later can help companies reduce diesel emissions, reduce risk, improve monitoring programs and keep their workers safe from DPM exposure.

None of the above can be achieved using sampling pumps and filter cassettes

Features & Benefits

  • 100nm to 15um wide particle size range
  • 1ug/m3 to 400mg/m3 particle concentration range
  • Measure PM1, PM2.5, PM4, PM10 & Total PM fractions
  • Real-time instant results, audible and visual alarms
  • Data logging with powerful Windows based software
  • 37mm filter sample collection
  • Rugged and reliable, easy to install in mines
  • Can be connected to external lights, alarms & buzzers. SMS and remote telemetry compatible
  • Optional lockable enclosure prevents tampering and is easily mounted on an L shaped bracket in any mine.

Vehicle Diesel Exhaust Test Systems

The latest test systems from WA based Mammoth Exhausts provide real-time on vehicle diesel particulate measurements. The technology has been around for nearly a decade and has been validated locally and internationally with many companies nationally now using their on vehicle test systems.

On vehicle testing can help companies reduce emissions and determine whether vehicle tuning is required and or the use of particle filters. Along with personal and background monitoring, it can play an important role in any exposure monitoring plan.
