Proforce recognises that central to the selection of the correct
respiratory device is the understanding of the hazard being faced.
The following key points require consideration before choosing
your respirator, disposable or cartridge type.

What is the name of the hazard
In what form is the hazard encountered
What other applicable regulations may effect selection
What is the Occupational Exposure Standard (OES) for the
hazard
What is the airborne concentration of the hazard
How long will worker(s) be exposed to the hazard within
any given 24hr period

With all of this information it is then possible to determine the
Time Weighted Average (TWA)

Long Term Exposure = (Concentration X Time of Exposure) / 8
Short Term Exposure = (Concentration X Time of Exposure) / 0.25

To determine the minimum required efficiency of the appropriate
filter divide TWA by OES. Proforce has a range of respiratory protection solutions to ensure that all hazards faced within the workplace have a suitable product against which you can protect.
There are five forms of hazard that are commonly encountered
within the workplace, these include,
Dust – formed by the breaking down of solid materials in general the smaller the dust particle the greater the hazard. Fibres of material should also be treated as dusts!
Mist – Formed by processes that involve atomisation and
condensation, such as spraying, and consists of tiny liquid droplets
Fume – formed by the vaporisation of a solid material by the application of intense heat. Extremely fine solid particles are formed as the vapour cools and condenses
Vapour – a gaseous state formed by evaporation from substances that are normally either solid or liquid at room temperature
Gas – an air like substance at room temperature. Gases can travel very far very quickly!
