Ergonomics of the thermal environment - Assessment of heat stress using the WBGT (wet bulb globe temperature) index

ISO 7243:2017 presents a screening method for evaluating the heat stress to which a person is exposed and for establishing the presence or absence of heat stress. It applies to the evaluation of the effect of heat on a person during his or her total exposure over the working day (up to 8 h). It does not apply for very short exposures to heat. It applies to the assessment of indoor and outdoor occupational environments as well as to other types of environment, and to male and female adults who are fit for work.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
