Good afternoon all,
Concerning provision of RPE, if the msds states to minimise inhalation of dust but does not specify p2 or P3, would it be considered best practice even though there is a "cost" implication to provide P3 protection?
Thanks in advance guys.

What is it that implies the need for a mask?
The MSDS tells you to avoid inhalation - perhaps you could consider this to read differently, preventing initial release and/or containment rather than release and then the use of a mask that would be far from ideal on so many levels.
Minimising inhalation might be better achieved by preventing release in the first place though different handling, containment, good ventilation/LEV etc
Better working environment, easier to control, no collateral exposure etc

With disposable masks I only ordered P3 for dust / fume even when a lesser standard would have been suitable
Shop around. I found that the cost difference was small and you ensure that the correct mask is drawn from stores and used.

Risky,
if you are using disposable masks for any degree of protection then you will need to ensure that employees have had face fit training and testing. Disposable masks arent good for long term use, and they are not "one size fits all". Clean shaven and correct fitting are basic reqt?

Risky,
We are currently addressing some issues of dust inhalation (generated by process). I'd agree that if possible you should look at other methods of control first.
If it still comes down to RPE, as it has with us. The protection factor (FFP 1, 2,3) selection should ideally be based on the level of protection required. If you know the actual exposure this would help you decide.
We have had problems where over-protecting leads to other issues, for example the FFP3 does become uncomfortable more quickly (more resitance to breathing). When using FFP3, valve mask's do help somewhat as exhaled air is not restriced by the filter.
I would aim to use the lowest level that adequately controls exposure but ensure the selection is backed up as necessary by air monitoring, face fit testing etc. Our final choice of mask is based on best fit and personal comfort.
Regards
