U)travue facepieces with the MSA Chemox oxygen-generating self-contained breathing apparatus.

This request is made in e

accordance with the instructionc provided in 10 CFR 20.103 (c).

originally approved by t.he Bureau of The Chemox respirator was Mines (Approval Nurbor 1307).

To de.te, the National Institute for Occupatior: 21 Safety and lloulth/Mine Safety and licalth Administration (NIOSil/MSilA) har extended the Bureau of Mines approval for use of the Chemox until further notice.

When the Chemox was originally

approved, only tro facepieces coulu be used with this respirator, and both were basically medium si ne +'acopieces.

Due to the fact that:

1) small and large size facepieces were not available when the Bureau of Mines approved the Chemox, 2) the Chemox respirator never received a

llIOSil/MSilA

approval, and 3) 10 CFR 20.103(c) requires that the iconsee shall uso equipment that is certified or had certification stended by ll10Sil/MSilA, we request authorization to use the following MSA Chemox facopieces:

.E 1.

Ultravue small liycar rubber (part number 476850) 2.

Ultravue r all silicone rubber (no part number) 3.

Ultravue large liycar rubber (part number 476851)

Both Ultravue Hycar rubber facopieces have been available as accessories to the Chemox respirator in recent years.

The Ultravue silicone rubber facepiece, however, had not been tested for use with the Chemox respirator by MSA unt il requested to do so by Beaver Va lley.

The results of this testing, which are attached for your

review, 19rified that the silicone rubbar had no detrimental effect on the cration of the respirator.

Based upon tho information presented we hereby rcquest 11RC authorization to use the dif ferent e

size Ultre ue facepieces specified.

Notabolic simulator testing was performed using an A4 closed-circuit breathing apparatus with a smal] silicone Ultravue facopicco.

The toat protocol followed was the current test plan performed on Chamox canisters for QC acceptance. _The purposo of the test was to dotarmine if there would be any adverse perfort.ance effects due te the change in the materiel and size of the facopiece.

The results of the testing showed no adverse effect; from the change in facepiece size and material.

Attached for your inf 0rnation and record are the graphs of the data collected during the test.

All parameters meet the requirements for the

~

Chemox canister and are within the expected values.
