For safety reasons, a respiratory protective mask must be worn to protect a worker from harmful dust, gases, vapors, particulates of various sizes including silica, and aerosols.

Getting the worker to consistently wear a mask is difficult.

Respiratory protective masks are a common piece of Personal Protective Equipment (PPE) and should be worn whenever there is contamination danger in the air.  A variety of occupations utilize masks including the military and medical facilities.  Respirators interfere with the performance of work tasks and should be taken into consideration if a worker is slower performing those tasks because of a mask.

Because of the physical size and limits on productivity masks come with burdens to the worker including:

Productivity is challenged because workers cannot perform as long or as hard while wearing a respirator.  If protective clothing is required along with the respirator, it makes the situation even worse.  Either more time is needed to complete the task, or additional workers must help to complete the task.

The wearer of the mask must be fitted properly, and even then, wearers have different tolerance levels to:

No two workers are alike when it comes to a respirator mask.  When the air is dirty with known silica particles, a respiratory mask should be worn.  What if you could detect when the mask should be worn?

Instantaneous, real-time monitoring of the air allows the worker to wear a mask less.

The company bottom line increases because the worker is more productive and only wears a mask when necessary.

At Nanozen, we offer a solution.  You can determine the highest exposure processes and have the workers wear a mask during those times.

By having your work processes tested for airborne particles with a unit mounted to a worker, you determine when masks are needed.
