License do. LPR-22 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 pro-tection factor for particulates and vapors and gases is considerably less than the expected factor of 500. As a result of these tests, technical specifications con -ining allowances for the use of e
respiratory protective equipment shall be changed to reflect a pro-taction factor of no more than 100 for full facapiece 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 the particular respiratory equipment by your technical specifications.
If the actual protection fastor is less than that I
given in your technical specification you should take corrective action to either repair your respiratory equipment, replace the defective equipment or reduce the allouable protection factor assigned to such respiratory equipment and reevalusta the exposures to any individual that'used such equipment in plant activities with~an assigned protectica factor greater than the actual value.
