RPD Selection Information

RPD may be required for protection against contaminants which are corrosive in nature. These contaminants may come into contact with the skin, eyes or the RPD, either as gaseous or aerosol contaminants, or by splashing of liquids from the work process. Selection of suitable RPD will need to include consideration of the interaction of the RPD with adequate and suitable chemical protective clothing.

Certain substances are capable of weakening components and parts of RPD. This may lead to a reduction in robustness of components over time. This would be of concern if the performance of the RPD is reduced, e.g. by damage to valves or if other protective elements of the RPD, e.g. helmets or eye protectors, were significantly weakened or rendered opaque. As a result, an enhanced maintenance and/or replacement schedule may be required for the RPD.

Advice from the RPD manufacturer/supplier should be sought on the suitability of the RPD for the environment, and the selection modified if appropriate.
