Temperatures in the indoor workplace are covered by the Workplace (Health, Safety and Welfare) Regulations 1992, which place a legal obligation on employers to provide a ‘reasonable’ temperature in the workplace.
Minimum workplace temperature
The Approved Code of Practice suggests the minimum temperature in a workplace should normally be at least 16 degrees Celsius. If the work involves rigorous physical effort, the temperature should be at least 13 degrees Celsius. These temperatures are not absolute legal requirements; the employer has a duty to determine what reasonable comfort will be in the particular circumstances.
Higher workplace temperatures
A meaningful figure cannot be given at the upper end of the scale due to the high temperatures found in, for example, glass works or foundries. In such environments it is still possible to work safely provided appropriate controls are present. Factors other than air temperature, ie radiant temperature, humidity and air velocity, become more significant and the interaction between them become more complex with rising temperatures.
Risk assessment
In addition to the Workplace Regulations, the Management of Health and Safety at Work Regulations 1999 require employers to make a suitable assessment of the risks to the health and safety of their employees, and take action where necessary and where reasonably practicable.
The temperature of the workplace is one of the potential hazards that employers should address to meet their legal obligations. Employers should consult with employees or their representatives to establish sensible means to cope with high temperatures.
