Re: Liquid penetrant test : : WHAT TYPE OF FILTER SHOULD I USE IN MY MASK WHEN PERFORMING LP IN A CONFINED SPACE LIKE A TANK? : edxrýcdýrcd
We manufacture locally in Australia the Ardrox range of penetrants and would suggest that respirators appropriate for organic vapours should be suitable eg 3M's OV. If product is sprayed OV P1 is preferred. The user should be aware that the life of the filter is affected by vapour concentration. We would suggest confirmation of the limitations of the respirators usable life with its manufacturer.
If the products are to be used in confined spaces, with high vapour concentration for a long period of time, then we would suggest using supplied air respirators. Regards David Smart
