Testing the Face Masks Used In Asbestos Removal
or
Keeping our Workers Safe
This Article is of the testing of Asbestos Testing/removal facemasks. If you have any doubt that we keep our workers safe during Asbestos Testing and removal than I hope this excerpt on the testing of Asbestos Face masks alone will change your mind.

Each exercise described above shall be performed for at least one minute. If at any time during the test the subject detects the banana-like odor of IAA, the test has failed. The subject shall quickly exit from the test chamber and leave the test area avoid olfactory fatigue. If the test is failed, the subject shall return to the selection room and remove the respirator, repeat the odor sensitivity test be failed, the subject shall wait about 5 min before retesting. Odor sensitivity will usually have returned by this time.
If an employee cannot pass the fit test described above wearing a half mask respirator from the available selection, full facepiece models must be used. When a respirator is found that passes the test the subject breaks the face seal and takes a breath before exiting the chamber. This is to assure that the reason the test subject is not smelling the IAA is the good it of the respirator facepiece seal and not olfactory fatigue.
When the teats subject leaves the chamber the subject shall remove the saturated towel and return it to the person conducting the test. To keep the area from becoming contaminated the used of towels shall be kept in self-sealing bag so there is no significant IAA concentration buildup in the test chamber during subsequent tests. At least two facepieces shall be selected for the IAA test Protocol. Test subject shall be given the opportunity to wear them for one week to choose the one which is more comfortable to wear. Persons who have successfully passed this fit test with a half mask respirator may be assign the use of the test respirator in atmospheres with up to 10 times the PEL of airborne asbestos. In atmospheres with up to 10 times and less than 100 times the PEL (up to 100 ppm), the subject must pass the IAA test using a full-face negative-pressure respirator.(The concentration of IAA inside the test chamber must be increased by ten time qualitative fit testing of the full facepiece.)
REGULATIONS
The test shall not be conducted if there is any hair growth between the skin and facepiece sealing surface. If hair growth apparel interfere with a satisfactory fit, then it shall be altered or removed so as to eliminate interference and allow a satisfactory fit. If a satisfactory fit is still not attained, the test subject must use a positive-pressure respirator such as a powered air purifying respirator, supplied air respirator, or self contained breathing apparatus.
If a test subject exhibits difficulty in breathing during the tests he or she shall be referred to a physician trained in respirator disease or pulmonary medicine to determine whether the test subject can wear a respirator while performing her or his duties.
Qualitative fit testing shall be repeated every six months at the least.
