Definitions

Dust



Generic term
Range of potentially hazardous particulates
Nuisance dust


Dust with no inherent toxic profile
Excess can overload lungs
4
Other particulates
Harmful health effects

Silica – lung damage

Metal dusts



nickel – cancer
manganese – manganism
lead – damage to central nervous system, kidneys,
blood cells
5
Latent health effects

Delayed


Onset of health effects following exposure
Insidious

Progressive and often irreversible changes to health

Dust management

Regulatory focus on fibre and dust management in
mining

Statutory obligation to manage dust emissions in
drilling operations

Obligation to monitor exposures to atmospheric
contaminants

Ensure exposures do not exceed occupational
exposure standards (OES)
7
Dust emission points
8
Controlling dust
Use water

Fog

Foam

Binders

Surfactants
9
Potential controls

Trialling of dust suppression agents (e.g. foam, fog)

Automated sampling

Sample conveyors

Remote operating controls

Operating cabins
