Conditions of use of disposable masks | JINHAOCHENG

What are the conditions for using disposable masks?Jinhaocheng is a professional disposable mask manufacturer.

Disposable masks are made of three or more layers of 28 grams of non-woven fabric;The bridge of the nose is made of environmentally friendly plastic strip, which does not contain any metal, and is breathable and comfortable, especially suitable for electronics factories and daily use.Disposable masks (surgical masks for medical purposes) can protect against respiratory infections to some extent, but not against smog.It is important to note that you should choose masks that are clearly marked "surgical mask for medical use" on the packaging.

There are many types of disposable masks, which must be selected according to different work requirements and working conditions.

The first should be based on dust concentration and toxicity.According to GB/T18664 "Selective use and maintenance of respiratory protective equipment", as dust masks, all dust masks are suitable for the environment where the concentration of harmful substances does not exceed 10 times the occupational exposure limit, otherwise, advanced respirators should be used for full masks or protection grade.

If the particulate matter is highly toxic, carcinogenic and radioactive, the filter material with the highest filtration efficiency should be selected.

If the particles are oily, be sure to select the appropriate filter material.

If the granular material is acicular fiber, such as slag wool, asbestos, glass fiber, etc., dust masks should not be washed with water, and masks with microfiber attached to the face seal can easily cause facial irritation and will not be suitable for use.

For high temperature and high humidity environment, choose mask with exhalation valve will be more comfortable.Selecting masks that remove ozone for welding can provide additional protection, but if ozone levels are more than 10 times the occupational health limit, replace the mask with a dust-resistant, toxic combination filter element.

For environments with no particulate matter but only some odors, for example, in some laboratory environments, the choice of dust masks with activated carbon layers is much lighter than the wearing of gas masks, but the use of such masks is not regulated due to standard reasons for technical performance.
