Dust masks are lightweight masks that are fitted over the nose and mouth and secured behind the head with elastic. They provide breathing relief from many types of air contaminants or vapours. Dust masks are usually disposable and come in a range of models:
- rated for different types of dust such as for mechanically or thermally generated particles
- masks with air valves and filters for protection against specific vapours
- masks made of varying materials for improved comfort over long periods
- masks that fold flat for easy storage
- high visibility dust masks
- dust masks with breathing valves for improved air flow
- single or dual elastic straps
- individually packed for extra hygiene
- colour coded nose pieces for identification purposes
- aluminium moulded nose pieces to allow individualised moulding and better fit and protection.
The provision of dust masks for protection should be part of a company’s comprehensive respiratory protection program within workplaces exposed to physical and vapour particles. Dust masks should be used to complement other air quality management control methods.
Workplace solutions and adjustments
As well as being a legal requirement for some workplaces, wearing a respiratory mask may be a necessity for people who have specific health needs including:
- a breathing condition such as asthma
- sensitivity to certain substances.
Other issues to consider in order to improve the condition of the air in the workplace include:
- allowing regular breaks
- ensuring windows and doors are open for ventilation where possible
- ensuring air conditioning and ventilation systems are well maintained
- tasks resulting in vapours or dust should be isolated from other areas of the workplace to minimise employee exposure.
