Above is lists of masks made by other countries when the US ones aren't available. Thanks?

OSHA Instruction:
Who needs to use masks,under what conditions,employer responsibilities and citationable actions or non-actions. Guidelines for what mask when and how to determine suitability.
Also-
"Fit Testing - Paragraph (f).
Fit testing is required for all employees using negative or positive pressure tight-fitting respirators, where such respirators are required by OSHA or where the employer requires the use of such a respirator. A fit test is not required for voluntary users or for escape-only respirators.
The fit test must be performed before the respirator is used in the workplace. It must be repeated at least annually and whenever a different respirator facepiece is used or a change in the employee's physical condition could affect respirator fit. If the respirator subsequently becomes unacceptable to the employee (i.e., causes irritation or pain to the employee), the employee must be given the opportunity to select a different respirator facepiece and be retested.
Qualitative Fit Testing (QLFT) may be used to fit test negative pressure air-purifying respirators if they will only be used in atmospheres less than ten times the PEL, since existing evidence only validates the QLFT protocols listed in Appendix A of the standard to identify respirators that achieve a fit factor of 100.
( I have been fit tested many times and have been the tester many times. The procedure is as I stated previously with aspartame solution as test substance.)

More guidelines and rational for decisions. None of the user guidelines are beyond the understanding of the average middle schooled person.
