§1910.95 (i)(j) Hearing Protectors
(i) Hearing Protectors
Make available to ‘ees exposed to 85 dBA over 8 hr. TWA
‘Er ensure protectors are worn
Worn by ‘ee exposed but has not had baseline audiogram
Worn by ‘ee that has experienced a threshold shift
‘Ee has opportunity to select from a variety provided by ‘er
Provide training in use & care of protectors
‘Er has to ensure proper initial fitting & supervise correct use
(j) Hearing Protection Attenuation (“Er responsibility)
Evaluation of protectors (Appendix B)
Must attenuate to at least 90 dBA
Must attenuate to at least 85 dBA or below for ‘ee that had experienced a threshold shift
Re-evaluate whenever the adequacy no longer provides adequate attenuation
