This is the basis of the “hierarchy of control” - a list of common control
measures in order of preference.

Let’s look at some examples of how it can be applied to
controlling common occupational carcinogens

We’ll start with how exposure can be
prevented

The use of asbestos has also been banned
![Page 14: Occupational cancer what you need to know](https://reader034.vdocument.in/reader034/viewer/2022052619/55519c8db4c9053c488b4845/html5/thumbnails/14.jpg)
The use of silica sand for blasting is not allowed. Alternatives must be used.

When we can’t prevent exposure, we should try to find engineering approaches to
control exposure

Respiratory protection really
shouldn’t be used as a primary control
for carcinogens
![Page 28: Occupational cancer what you need to know](https://reader034.vdocument.in/reader034/viewer/2022052619/55519c8db4c9053c488b4845/html5/thumbnails/28.jpg)

But it may be needed in some situations as a
secondary control or where other
approaches aren’t practicable

Good training and supervision is needed to make sure respiratory protection is effective
