What respirator do I use for concrete dust?

What respirator do I use for concrete dust?

The 3M 8511 N95 particulate respirator is provide protection against non-oil based particles such as wood shop dust and concrete dust. The 3M 8511 respirator is well suited for work settings that involve heat, humidity, or long periods of wear.

Does P100 protect against dust?

Protection from debris and materials that are larger than 0.3 microns or greater can be achieved with N100 and P100 respirators are ideal for dusty and oily applications. These respirators filter 99.7% of airborne particles. The “N” designation means that these respirators are not resistant to oil.

What type of mask is required for silica dust?

N95
NIOSH recommends the use of half-facepiece particulate respirators with N95 or better filters for airborne exposures to crystalline silica at concentrations less than or equal to 0.5 mg/m3.

What happens if you inhale cement dust?

Crystalline silica is found in materials such as concrete, masonry and rock. When these mate- rials are made into a fine dust and suspended in the air, breathing in these fine particles can produce lung damage. Silicosis can be totally disabling and may lead to death.

How many microns is concrete dust?

It represents a major pollution problem in Egypt where around 2.4 million tons per year of cement dust is diffused into the atmosphere causing air pollution problems because of its size (1-10 microns) and alkalinity (pH 11.5).

What does P100 protect against?

P100 filters are strongly oil-resistant, which means they can protect against all types of solid and liquid particles in the atmosphere and can be used (but degrade faster in) atmospheres with oil-based particles.

What does a P100 respirator protect against?

NIOSH-approved P100 Particulate Filter for respiratory protection against certain oil and non-oil based particulates.

Is a P100 filter good for asbestos?

Any filters used for protection in atmospheres with asbestos need to be rated P100. Also called HEPA filters, the P100 is a NIOSH rating. NIOSH is the National Institute of Occupational Safety and Health. The P100 respirator filters block at least 99.97% of airborne particles and are strongly resistant to oil.

How do I clean my lungs after inhaling dust?

Ways to clear the lungs

1. Steam therapy. Steam therapy, or steam inhalation, involves inhaling water vapor to open the airways and help the lungs drain mucus.
2. Controlled coughing.
3. Drain mucus from the lungs.
4. Exercise.
5. Green tea.
6. Anti-inflammatory foods.
7. Chest percussion.

What are powered air purifying respirators (PAPRs)?

Powered air-purifying respirators (PAPRs) use a fan to draw air through the filter to the user. They are easier to breathe through than negative pressure air purifying respirators; however, they need a fully charged battery to work properly. PAPRs have three filter classes HE, PAPR100-N, and PAPR100-P.

Is the NIOSH P100 mask NIOSH approved?

NIOSH P100 Approved. Provides at least 99.97% filtration efficiency against solid and liquid aerosols, including oil based aerosols. * Professional Series silicone facepiece provides greater softness, comfort and durability. Easy-to-adjust, comfortable head strap assembly. Categories: Half Mask, Kits, Respiratory-NIOSH Approved.

What is the dust (or mist) collection efficiency of dust filters?

The dust (or mist) collection efficiency of filter materials also varies. Filter cartridges are available in three efficiency levels: 95%, 99%, and 99.97%, designated as 95, 99, and 100. For example, an N95 filter is 95% efficient; an N99 filter is 99% efficient; and an N100 filter is 99.97% efficient.

What type of dust filter do I need for my workplace?

P-Series filters are oil-Proof. For mineral dusts, such as silica, any of these filters will work unless the workplaces has an oil mist source. The most common oil mist sources in construction comes from percussion drills. These workplaces should use type R or P filters.
