Key Benefits of the CM-7M Military-grade Gas Mask: Outstanding resistance against all kinds of CBRN agents, industrial toxic gases, riot control gases, etc. The military-grade technology used for this full-face respirator provides comprehensive protection against the full spectrum of CBRN agents and toxic industrial chemicals in the form of gases, vapors, and aerosols. Although the M-17 may be purchased at an attractive price as compared to the currently approved gas masks, the level of protection provided by this mask is questionable.The CM-7M tactical gas mask is the ultimate chemical, biological, radiological, and nuclear (CBRN) defense system when used in conjunction with suitable filters or breathing apparatus. Besides, users can no longer obtain spare parts and fresh canisters from MSA. The facepiece may have deteriorated and the sorbent probably has lost effectiveness over such a long storage time. Furthermore, the currently available M-17 masks were manufactured at least ten years ago. There is no reason for OSHA to accept the M-17 under a variance situation on the basis of unavailability. There are many approved gas masks available with modern design, improved construction materials, and with different types of canisters for protection against a wide variety of air contaminants. Since the M-17 is not approved by MSHA and NIOSH, this respirator may not be used by workers other than enlisted military personnel. MSA does not recommend the use of this mask by civilians. It may not pass the certification tests currently administered jointly by the Mine Safety and Health Administration (MSHA) and the National Institute for Occupational Safety and Health (NIOSH) under the provisions of. Furthermore, this mask was made in accordance with specifications for military use. Since the Defense Department owns the mold, MSA no longer stocks spare parts for this mask. From my conversation with a technical representative of MSA, I learned that the production of the M-17 was terminated in the early seventies. The Mine Safety Appliance Company (MSA) was the principal manufacturer of the mask under contract with the Department of Defense. The M-17 gas mask is used for the protection of army personnel against chemical warfare. This is in response to your letter of March 24, concerning the use of nonapproved M-17 gas masks.
