Abstract Neither rationalisation of ventilation nor air conditioning can solve all the problems in coal seams where there are severe climatic conditions. In the case of an effective temperature of less than 35°C and a low velocity air flow (0.5m/s), merely stirring the air by ordinary ventilation is enough to improve conditions considerably. With temperatures above 35°C, however, either the air blowing on the individual worker must be cooled, or else the worker must wear cooled clothing. Research in this field has shown that priority must be given to cooling the head and trunk, that cooling by dry ice is very effective but is ergonomically unsatisfactory, and that the simplest and most effective solution is to issue workers with a hooded jacket of double sponge fabric soaked in cold water (15°C). This article is illustrated by many tables and graphs showing, in particular, pulse rate variations when different types of cooled suits were worn.
