I would appreciate the views of those with competence in this topic on the following:-
What is the concensus on the continued use of P3 filters used for asbestos removal on full & half-mask non-disposable respirators? Should they be retained after having transited the shower and re-used the next day/shift; or should they be diposed of at end of shift?
Please do not just give me chapter & verse of CoSHH etc without identifying the relevance to the question.
I shall await all responses with great anticipation.

Yes, P3 filters can be re-used but it is all down to how well the asbestos work is supervised. The operative may re-use but it is imperative that the filter is capped when showering. The asbestos supervisor must ensure that the conditions where the filter is being used are correctly monitored and that stated control measures are being adhered to and remain effective throughout. The operative must be conversant in the decontamination procedures and know when their filter needs to be changed. Effective training and supervision should address this. P3 Filters are robust and designed for more than single use provided the asbestos work is well controlled and decon procedures are followed. P3 filters can be used over a number of shifts/ days as long as they are used correctly as stated.
