Health Care of People at Work

摘要

In order to appraise management of the restrictions necessary for work at 27°C and above, or when impermeable clothing is worn, a device called the Thermoguide has been produced. It contains information written on both sides of a card which fits into a jacket pocket. Definitions of the type of work undertaken at different dry and wet bulb temperature readings are given and these times are altered by clothing, the wearing of a respirator or a change in ventilation.When impermeable clothing or air-cooled suits are worn, information is given regarding air supply, temperature and the need for a medical opinion. Additional information is given on rest periods, replacement of fluid loss and the need for individual health assessment. The Thermoguide catalogues the type of health check that should be made by a supervisor before hot work is undertaken. The signs and symptoms of impending heat disorders are listed and a description of an incident when two men experienced heat stress is given. The Thermoguide has been found to be a useful means for management to control the type of work and working conditions of those exposed to excessive heat
