After using a dust-mask respirator, cutting the straps before disposal is an essential best practice. This action prevents re-use of the mask by anyone else, which could pose a health risk if the mask was contaminated during use. In a laboratory or industrial setting, maintaining hygiene and safety is paramount, and ensuring that potentially hazardous materials do not stay on the masks supports this goal.

Additionally, cutting the straps helps to signify that the mask is no longer usable, reducing the chances of it being mistakenly reintroduced into circulation. It's crucial to handle personal protective equipment (PPE) responsibly, and disposing of it properly is part of a broader commitment to safety protocols.

Storing it in a clean area or disinfecting it may not be applicable practices, as dust masks are often designed for single use. Reusing a dust mask can compromise its effectiveness and increase the risk of exposure.
