As a company Dust Monitoring Equipment (DustWatch CC) offers many services that fall under our expertise:
Dust Control Design
These systems are used where material is conveyed or moved in such a way that fine dust particles are liberated.
Dust control or dust extraction systems are used to prevent dust from escaping and precipitating on the ground. A common misconception is that these systems actually remove fines from the product being transferred.
Occupational & Hygiene Audits
Legally, concerns that fall under the Department of Minerals and Energy in South Africa are required to have audits done.
These audits include the following investigations among others:
- Light or Illuminations
- Safety and Hygiene
- Respirable dust
This involves the determination of the exact dust or fume load in a stack, or dust plant. This is used to determine efficiencies of dust plants, calibrate dust/fume measuring devices and determine stack emissions.
PM 10 Sampling
The focus on PM10 particulate (particles with a d50 aerodynamic diameter of 10 microns) has increased internationally and in South Africa. New legislation now requires dust-generating activities to monitor for PM10 if the fallout dust levels exceed the respective residential or non-residential limit, of 600 and 1200mg/m2/day respectively.
This involves sampling for respirable dust particles (particles with a d50 aerodynamic diameter of 7 µm or 7 microns). These particle sizes are proportionally not kept out by the nasal system and pass into the lungs. Any sharp particles and or particles that go in and don’t come out can lead to serious health problems.
Noise & Illumination Assessments
These normally form part of the occupational audits but sometimes these investigations are required for a certain problem area. An example of this is the loudness of hooters and the effectiveness of headlights on earth-moving vehicles.
Water and Gas Sampling
This service includes the taking of samples and getting them analysed for the required substances.
