When wearing a respirator, where do the straps go?

When wearing a respirator, it is crucial that the straps are positioned correctly to ensure an effective seal around the face. The correct placement of the straps, which is under the hoods of protective suits, serves to enhance the fit of the respirator and minimize the risk of contaminant ingress. This positioning helps to ensure that the respirator is secured firmly against the wearer’s face, thereby optimizing its protective capabilities.

Straps situated under the hood prevent movement that could disturb the seal, maintaining the integrity of the respiratory protection even when the wearer is engaged in tasks that may involve physical exertion or changes in head position. This is particularly important in environments with airborne contaminants, where maintaining a tight seal is essential for the safety of the worker.

In contrast, other placements such as over the head only, around the neck, or attached to the suit's collar do not provide the same level of security, potentially allowing harmful substances to enter through gaps or breaches in the seal.
