Field Notes: The M95 Respirator by Mike Conti Please note this is not an advertisement. Saber Group, Inc. has no financial or other ties to any respirator manufacturer or distributer. This information is being provided solely for informational purposes. This information is in no way complete in regard to the M95 Respirator, nor does it constitute a thorough overview regarding the operation or employment of the M95 or any other respirator. Saber Group, Inc. assumes no liability whatsoever for the use or misuse of any of the information provided here. Always seek out qualified instruction prior to employing any equipment, methods, or techniques shown on this website.
The Safety Tech International M95 Full Facepiece Respirator
The M95 FULL FACEPIECE RESPIRATOR is an ergonomically-designed, comfortable, and effective respirator. I have worked extensively with this and many other respirators over the past 26+ years in the military, police, and private industries, and believe the M95 to be one of the better negative-pressure respirators available for tactical applications - especially when coupled with the M95 Filter Cartridge. Prior to employing this or any respirator, the user must be familiar with the design and operational capabilities and limitations of the specific device used. Therefore it is strongly suggested that the manufacturer's information be accessed and read thoroughly until a complete level of understanding is achieved. For information about the M95, click here or on the image at right. As stated above, professional instruction in the operation and employment of this type of equipment is mandatory to ensure the highest margin of safety for you and your personnel.
Safety Notes Like any piece of equipment, the M95 Respirator will only work as designed when assembled and used correctly. The M95 utilizes a number of modular components which must be installed properly prior to use. While the filter cartridge (shown attached to the mask in the image at left) is the most obvious, other components must be checked as well. A few (but not all) of these components are shown below in a series of photographs. Components selected for illustration based on field use experiences. NOTE: Do not over tighten the filter cartridge when screwing it into the Filter Cartridge Connector Port! You can dislodge the Inhalation Valve resulting in an improper seal.
Ensure that there is an Inhalation Valve installed in BOTH the right and left (Inhalation) Cartridge Connector Ports, regardless of which port you are installing the filter cartridge into. The (Inhalation) Cartridge Connector Port not being used for filter cartridge attachment is filled by a gray plug. The plug screws in clockwise and must be seated firmly. The Inhalation Valve consists of two green silicone components: the Valve Disk and the Valve Seat. When assembled correctly the Disk sits flush against the Seat (image below right). The image below left shows what you should see when the Filter Cartridge is removed. This is what is should look like if the Inhalation Valve is assembled and inserted into the mask correctly.
NOTE: The green silicone Valve Disk is connected to the green silicone Valve Seat by inserting the Disk's thin nipple through the Seat's center hole. The Disk's nipple should be left alone once the Disk is seated properly. Do not over-pull the Valve Disk's protruding nipple through the center hole of the Valve Seat as it will cause the Valve Disk to deform as shown in the images below!
If the Inhalation Valve Assembly looks like those shown below, or if either or both Inhalation Valve components are missing, distorted, or damaged, IMMEDIATELY notify your Chemical Agent Officer!
IF YOU HAVE ANY DOUBTS DO NOT EMPLOY THE MASK UNTIL IT HAS BEEN INSPECTED AND REPAIRED!!! NOTE: The Valve Disk will deform in the manner shown below if the Valve Disk's protruding silicone nipple is pulled too far through the center hole of the Valve Seat. This will render the Inhalation Valve inoperative!
Left: Inoperative Inhalation Valve Assembly, front view. Right: Same Inoperative Valve Assembly, rear view.
Exhalation Valve Assembly *** Correct!!! *** Gently unscrew the Exhalation Valve Assembly and remove it from the mask.
The Exhalation Valve Assembly should look like the one shown at right. If it does not, IMMEDIATELY notify your Chemical Agent Officer! IF YOU HAVE ANY DOUBTS DO NOT EMPLOY THE MASK UNTIL IT HAS BEEN INSPECTED AND/OR REPAIRED!!! Once inspected, screw the Exhalation Valve Assembly clockwise into the Exhalation Valve Connector Port until it seats. Ensure it is firmly seated. Nosecup Assembly The M95 is equipped with a gray silicone Nosecup Assembly (shown below). In addition to ensuring that the Nosecup Assembly is properly installed within the facepiece, you must also ensure that the two green silicone Nosecup Valve Disks and the plastic Valve Seats are installed in the Nosecup itself. The image below shows how the Nosecup should look when these components are installed properly. Note: Also visible in the center of the Nosecup is the green drinking device tube.
The image below shows the Nosecup with one of the Inhalation Valve Seats and Disks missing.
If the Nosecup Assembly has any missing, distorted, or damaged components such as illustrated above, IMMEDIATELY notify your Chemical Agent Officer! IF YOU HAVE ANY DOUBTS DO NOT EMPLOY THE MASK UNTIL IT HAS BEEN INSPECTED AND/OR REPAIRED!!! Summary As always, professional instruction in the operation and employment of this type of equipment is mandatory to ensure the highest margin of safety for you and your personnel. Certified, knowledgeable and competent instructors should be sought prior to purchasing, training with, or employing any critical equipment. Considering what the respirators are intended to be used for, there are few more critical pieces of equipment we may possess. |
