Dust

WHY IS DUST SUCH A PROBLEM?

Dust is present everywhere, but when it is inhaled in large quantities or for extended periods it can be very dangerous to health. It can cause the following problems:

• The particles can enter the bronchioles of the lungs, causing respiratory and other diseases. This is especially so in the case of fine particles, as they penetrate the lungs easily and are very difficult to expel.
• Dust is a breeding ground for microorganisms, including bacteria and viruses.
• The dust may contain components such as lead, silica or synthetic mineral fibres which are highly toxic or harmful to humans.

HOW IS DUST MEASURED?

To determine the amount of dust in an environment, measurements are taken with constant volume air sampling pumps, high volume air samplers, or with dust deposit gauges.

To check the composition of the dust and scan for harmful elements, the dust may be analysed for toxins such as lead or silica, and visually examined for synthetic mineral fibres and asbestos fibres.

To see whether the dust is composed of the more dangerous finer particles or the less harmful larger particles, the particle size can also be determined on the spot with a laser particle meter. The dust is drawn through a laser cell and an immediate readout of the particle sizes is given.

WHERE CAN DUST BE MEASURED?

Dust can be measured in both indoor and outdoor environments, wherever there may be a potential hazard to health. Dust measurements can be taken from a static workplace, or alternatively from a particular person to see how much dust is likely to be inhaled by the individual.

HOW CAN NEW ENVIRONMENT HELP?

We can tell you if a dust problem exists, and if there is a problem what is it and what can be done about it. New Environment is NATA accredited for air volume measurement.
