Surgical masks are disposable products. With the duration of wear, the respirator mask becomes soaked and no longer offers protection. In any case, the masks should be disposed of if they become soiled, soaked or damaged, or after 2 hours at the latest.
In pandemic use, it can be assumed that the masks will be worn at short intervals: e.g. when shopping, refuelling, on public transport or whenever the minimum distance cannot be maintained. We recommend storing the mask in a closed bag between wearing intervals and hanging it up to dry at home. When doing this, you should make absolutely sure that no other objects are contaminated by it. Hand hygiene when putting on and taking off the mask should also be followed very carefully.
