Strenger can help you to ensure that your workplace is compliant with British and European Standards requirements and HSE guidance. Our approach is to measure, assess, evaluate and design remedial measures to control thermal stress within the workplace.

The further one’s thermal state drifts from their state of ‘thermal comfort’, then the higher their risk of being exposed to heat stress or cold stress becomes. Although ambient temperature plays a significant role in determining one’s level of thermal stress, it is important to consider a range of environmental and personal factors.

Strenger undertake thermal stress assessments in accordance with the following British, European and International standards:

ISO 7243 (1989) Hot Environments – Estimation of the heat stress on working man, based on the WBGT-index (wet bulb globe temperature)

ISO 11079 (2007) Ergonomics of the thermal environment – Determination and interpretation of cold stress when using required clothing insulation (IREQ) and local cooling effects

BS EN ISO 7933 (2004) Ergonomics of the thermal environment – Analytical determination and interpretation of heat stress using calculation of the predicted heat strain

BS EN ISO 9886 (2004) Ergonomics – evaluation of thermal strain by physiological measurements

BS EN ISO 13732-1 (2006) Ergonomics of the thermal environment – Methods for the assessment of human responses to contact with surfaces – Part 1: Hot surfaces

BS EN ISO 13732-3 (2008) Ergonomics of the thermal environment – Methods for the assessment of human responses to contact with surfaces – Part 3: Cold surfaces
