Safe Working in Extreme Heat.

Following the Met Office’s first-ever “Red Extreme” heat warning of 2022, it’s vital for organisations to implement measures to ensure the welfare of their employees during extreme heat. There are no laws defining when it’s too hot to work as workplaces with hot processes—such as bakeries, glass works and foundries—would not be able to comply. However, under the Workplace Regulations 1992, employers should provide a “reasonable” temperature in which to work. While what is considered “reasonable” will vary between industries, the Trade Union Congress recently recommended a maximum temperature of 30C for most organisations and 27C for those doing strenuous work.

Mitigate Risks With These Measures
A number of health and safety risks are associated with heat, including dizziness, dehydration and fainting. Additionally, employees exposed to high workplace temperatures may be less productive, which could have wider effects on organisational profitability. 

• Relax the dress code - as doing so will allow employees to work more comfortably. Organisations could allow staff to remove jackets and ties and dress in casual lightweight clothing on a temporary basis.

• Adjust the office -  in order to reduce the effects of high temperatures. Closing blinds during the day may help lessen the sun’s heating effects, and providing fans can help increase air movement. 

• Consider flexible working -  it might be sensible for employers to allow a degree of flexibility on when and where employees can work during hot spells. For example, a temporary change in working hours— allowing staff to work earlier or later—may allow employees to avoid commuting during the hottest part of the day. Employees may also benefit from regular breaks to cool down.

• Keep an eye on vulnerable employees. Although important to consider all employees, some staff members may be more susceptible to heat stress. Employers could encourage staff to raise any health and well-being concerns during heatwaves.

• Remember outdoor workers. As well as being exposed to high temperatures, outdoor workers are susceptible to the sun’s harmful ultraviolet rays. Organisations could implement guidance such as regular breaks in the shade and frequent hydration. They could also provide sun protection, such as hats with neck covers.

Organise a risk assessment.

Extreme temperatures are among the potential hazards that must be addressed for organisations to keep employees safe. If a workplace is continually experiencing high temperatures during the summer months, employers may wish to conduct a full risk assessment. This will help them determine which steps can facilitate the welfare of workers during high temperatures.

Conclusion

By implementing mitigation measures, not only will employers help ensure the health and safety of employees, but workers will also be more likely to perform work duties to usual standards.
