TY - JOUR AU - Coles, R R A AB - 1016 Proc. roy. Soc. Med. Volume 63 October 1970 S6 This suit is generally worn with a disposable PVC oversuit for ease of decontamination and the operator may require on occasion additional protective garments such as leaded or flameproof aprons. This means that he must be lightly clad if work is to be within the suit strenuous performed. User comfort: Thermal comfort can be main- tained by a flow rate of respirable air of around 0*14 ml/min. The airflow rate is more important than air pressure in maintaining a good supply of respirable and cooling air. A pressure differential between outside and inside of the suit is adequate at 1 in (2-5 cm) water gauge. Noise produced by the incoming airflow can be quite high at these flow rates, hence the addition of the silencing device. Most workers, however, confess to a greater feeling of safety if they are constantly aware of the hiss of incoming air. Maximum safety in operation is best achieved by the close supervision of the worker and his air supply from a control point, preferably with intercommunication facilities. The latter are essential if the operator is to be outside direct visual control.
