7.4.1 - Introduction

A sauna is a room in which the air is heated to a high temperature, humidity usually being very low, but occasionally increasing when water is deliberately poured over the heater. People using a sauna are usually unclothed and often wet (mainly due to perspiration), the absence of clothing (particularly shoes) removing much of their protection from shock (see{3.4.2}).

Special Regulations for saunas are new in the 16th Edition. As with bathrooms and swimming pools, zones are again classified, but this time they are concerned more with temperature levels than contact with water.

Zone A
The volume within 0.5 m horizontally from the Sauna heater and extending from the floor up to within 0.3 m from the ceiling.

Zone B
The volume covering the whole of the sauna room outside zone A up to 0.5 m above the floor

Zone C
The volume directly above zone B and extending upwards to within 0.3 m from the ceiling.

Zone D
The volume covering the whole floor area of the room and extending down from the ceiling for a distance of 0.3 m, including the space in this volume directly above the sauna heater.

The extents of the four zones are shown in {Fig 7.4}.
