It is designed to help focus on the most appropriate respirators in the 3M range for particular applications. It should not be used as the only means of selecting a respirator. Details regarding performance and limitations are set out on the respirator packaging and fact sheets. **A range of filters is available for these respirators.

It means that if you work with materials that contain silica and you work in an area where silica can become airborne – due to concrete cutting, grinding, coring, stoning, cement mixing and sweeping, or sandblasting – you need to wear a respirator. Some straightforward facts about respirators and silica dust

Here is the best respirator when using concrete. When you are working with concrete there's lots of dust particles in the air, and that's what you want to keep out of your lungs. Many people work with concrete on a daily basis and are needing concrete masks for their companies and small crafting business. So let's discuss concrete & cement safety.

Respirators may slow the work process and reduce productivity. Compared to the use of respirators without an effective program, a well-managed program can minimize the negative impact of respirators on productivity. Engineering controls that eliminate the need for PPE with the associated tasks generally improve productivity.

Agricultural Safety and Health) The disposable particulate respirator is commonly referred to as a dust mask, but it should not be confused with a nuisance dust mask.Main uses for the disposable particulate respirator include protection from dusts, mists, and some fumes in jobs such as haying, applying fertilizer, and …

Recent studies have shown that wet concrete cutting can drastically reduce the levels of respirable silica dust in a worker's environment. Water-fed control equipment is useful in cutting concrete without dust, and it is especially helpful in the grinding and polishing of concrete, as well as the cutting of materials with abrasive wheels.

or concrete products above recommended limits, wear a suitable NIOSH –approved respirator with protection factor appropriate for the level of exposure. For emergency or nonroutine operation- s (e.g., confined spaces), additional precautions or equipment may be required. Respirator use must comply with applicable MSHA or OSHA standards.

The most important safety hazard of grinding and polishing concrete you need to know is that of silica dust. Both grinding and polishing concrete produce silica dust as a byproduct. This dust is extremely fine and can easily get into your lungs. If it does get into your lungs, you run the risk of it affecting your respiratory system permanently.
