. Change No. 11 License No. DPR-25 Gentlemen:

Recent tests by the AEC Respiratory Studies Group at LASL of full facepiece respirators operating in the demand mode as currently approved by the U. S.

Bureau of Mines have indicated that the protection factor for particulates and vapors and gases is considerably less than the expected factor of 500.

As a result of these tests, technical specifications containing allowances for the use of respiratory protective equipment shall be changed to reflect a protection factor of no nore than 100 for full facepiece respirators operating in the demand mode for atmosphere-supplying respirators, both airline and self-contained breathing apparatus.

Also, your procedures for determining protection factors afforded by each of the respirator types currently in use at your facility should be reviewed to determine that the protection afforded the individual wearing such respiratory equipment is at least the protection factor assigned theIf the particular respiratory equipment,by your technical specifications.

act9M protection factor is less than that given in your technical specification, you should take corrective action to either repair your res-replace the defective equipment or reduce the allowable i

piratory equip =ent, protection factor assigned to such respiratory equipment and reevaluate the I

ayosures ca aay individual that used such equipment in plant activities with an assigned protection factor greater tuan the actual valua.
