3M R95 respirator for protection from oil based particles & low concentration of acid gases. Sold per box, 20 units/box.

3M R95 NIOSH 42 CFR 84 approved particulate respirator for welder’s protection from metal fumes and equiped with a Cool Flow™ valve. Sold per box of 20 units, 6 boxes/case.

This respirator is made of a patented electrostatically charged microfiber covered by a thin carbon layer that makes breathing easier and cooler while protecting from vapours. It is certified R95 which means it protects the user from 95% of the solid, liquid and non-oil based particles in the air. The letter "R" stands for "resitant", thus the membrane can resist oil based particles for a limited time, while it protects from solid, liquid and biological airborne contaminants.

The 8246 features stapled dual point attachment straps which provide a secure fit and a flexible and foam coated nosepiece which allows a better impermeability without putting aside comfort and a wider surface area which provides a better steadiness and a secure fit. Made in the USA.

Use for:
This respirator has been design for long term work in warm and damp environments. It is design to prtotect one from oil based liquid and sprays particles emit harmful organic vapours (solvents, degreasing agents, resins).

It is design to be used when manipulating oil based liquids from sprays that emit harmful concentration of acid gases like sulphur dioxide, hydrogen fluoride and/or chlorine. It may also be used in environments with low levels of acid gases. It is recommended for activities generating low levels of acid gases like glass etching, chemical processing, paper treatment, aluminum smelting and brewing operations. NIOSH certified respirators (N95, N100, R95, R100, P95 and P100) protect one from silica, the second main cause of chronic respiratory problems after asbestos.

Biological particles:
This respirator helps prevent the inhalation of certain airborne biological particles like mold, Bacillus anthracis (Anthrax), Mycobacterium tuberculosis (Tubercle bacillus Koch) the main causative agent of tuberculosis, pandemic flues (H5N1, H1N1), etc. However, it cannot eliminate the risk of contracting infection, illness or disease. Due to the nature of some contaminants, the exposure limit value of some products and byproducts haven’t been quantified by governmental agencies, thus wearing a respirator doesn’t necessarily protects you.

Do not use for:
Do not use on a beard and other facial hair or if the user suffers from a condition that prevents him from having direct contact with the respirator’s sides. The use of respirators is not recommended to people with compromised respiratory system such as asthma or emphysema. It is strongly discouraged to wear a respirator for application with oil based spray, brush painting, gases, vapours, asbestos and sandblasting. It is also highly advised to stay away from environment that exceed 10 times the permissible exposure limit set by the CNESST or any other government regulation applicable.One should never use a respirator in an oxygen deprived environment (an atmosphere with less than 19,5 % oxygen).

Whenever the respirator is well adjust and a qualitative fit test is successful, this respirator meets ANSI Z92.2-1992 standards, that is, a protection factor of 10. This factor means that the worker can be exposed to a concentration 10 times higher than the exposure limit when not protected. If needed, please contact customer service for more information.

Maintenance and service life:
No maintenance is needed since this respirator is disposable.  It has been design for an approximate service life of 8 hours. That number is in no way a reference since every work environments is different. The manufacturer’s limitations must be followed.
