3M 8512, N95 fireproof particulate respirator with Cool Flow valve for protection from metal fumes. 10 units/box.

3M 8512 N95 Flame‑Resistant Mask for Metallic Fumes

Compliant with NIOSH standard 42 CFR 84. Sold by the box.

Ten masks per box, eight boxes per case. The 3M 8512 N95 flame‑resistant mask is designed to provide high‑performance respiratory protection in environments where workers are exposed to solid particles, metallic dust, and welding fumes. Thanks to its N95 filtering media, it captures at least 95% of airborne particles while maintaining smooth breathing through the Cool Flow valve. Its flame‑resistant and durable shell allows safe use in hot environments or areas exposed to sparks. This respiratory protection mask is made of a patented electrostatic filter coated with a layer of flame‑resistant carbon fiber capable of withstanding small amounts of metallic vapors. It is N95 certified, meaning it captures airborne particles with 95% efficiency.

The letter “N” means “non‑resistant,” indicating that the filtration membrane does not resist oily particles but protects against solid, liquid, and biological particles. The 8512 mask is equipped with the Cool Flow™ valve, a 3M innovation. This valve quickly evacuates the heat generated by exhalation while significantly reducing fogging in safety glasses. The result is real comfort and increased safety for the worker. The product is manufactured in the United States. Provides basic protection for workers. Compatible with safety glasses.

This disposable 3M respirator stands out for its comfort, reliability, and ability to reduce heat buildup, making it a preferred choice for metalworking, manufacturing, and industrial maintenance professionals.

Features of the 3M 8512 N95 flame‑resistant mask and metallic vapor‑resistant mask

 The 3M 8512 N95 flame‑resistant mask stands out for its heat‑resistant shell and its anti‑clogging filtering media, especially designed for environments containing metallic particles. Its Cool Flow valve reduces internal humidity and facilitates the expulsion of hot air, improving comfort during extended wear. The braided straps ensure stable support, while the adjustable nose clip guarantees optimal sealing for consistent respiratory protection. This mask was designed for long‑duration work where the worker is exposed to hot and humid temperatures. It is ideal for workers involved in metal casting, brazing, cutting, welding of stainless steel, aluminum and galvanized steel, as well as other activities generating metallic vapors. It also protects against liquid particles from non‑oil aerosols that do not release harmful vapors. NIOSH‑approved masks (N95, N100, R95, R100, P95, and P100) offer a sufficient level of protection against silica, the second leading cause of chronic respiratory problems after asbestos.

Installing the 3M 8512 N95 flame‑resistant mask with Cool Flow valve

To properly install the 3M 8512 N95 flame‑resistant mask, position the shell over the face covering the nose and mouth, then place the straps behind the head to achieve a firm fit. The nose clip must be carefully molded to ensure an effective sealing and prevent air leaks. A quick fit check by lightly inhaling and exhaling confirms that the respirator is properly sealed.

Maintenance and Replacement of the 3M 8512 N95 Flame‑Resistant Mask

This product is disposable, so it requires no maintenance. It was designed to have an estimated service life of eight hours. This figure is for informational purposes only and should not be the sole tool for estimating the lifespan of your mask. Since every work environment is different, it is important to follow the limits established by the manufacturer.

Usage recommendations for the 3M 8512 N95 mask for welding fumes and metallic particles

 To ensure optimal protection, the 3M 8512 N95 flame‑resistant mask must be used in environments containing solid particles, metallic dust, or welding fumes. It must not be used for gases, vapors, or hazardous contaminants such as asbestos or lead. The user must always check the fit before each use and respect the recommended exposure limits to ensure effective N95 filtration.

Biological particles:

This respirator helps reduce inhalation exposure to certain airborne biological particles, such as mold, Bacillus anthracis (anthrax), Mycobacterium tuberculosis (tuberculosis), and pandemic influenza viruses (H5N1, H1N1), etc. However, it cannot completely eliminate the risk of infection, disease, or illness. Due to the nature of certain biological contaminants, government agencies have not been able to determine exposure limits for all types of contaminants.

Restrictions:

Do not use if the user has a beard or any condition preventing direct contact between the mask’s edge and the face. Do not use if you suffer from a respiratory disease such as asthma or emphysema. It is not recommended to use this mask when handling spray paint, oil‑based aerosols, gases, vapors, asbestos, particles released during sandblasting, or aerosol concentrations exceeding ten times the exposure limit allowed by the CNESST or any other applicable government regulation. This respiratory protection mask must only be used in areas that do not present an oxygen‑deficiency risk. When the mask is properly fitted and the qualitative fit test is successful, this respirator meets the ANSI Z92.2‑1992 standard, providing a protection factor of 10. Therefore, the worker may be exposed to certain airborne contaminants at concentrations up to ten times the established exposure limit. If needed, contact our customer service for more details.
