An effective hearing conservation program must be implemented by employers in general industry whenever worker noise exposure is equal to or greater than 85 dBA for an 8 hour exposure or in the construction industry when exposures exceed 90 dBA for an 8 hour exposure. This program strives to prevent initial occupational hearing loss, preserve and protect remaining hearing, and equip workers …

Sep 13, 2000 · With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8 hour day. Occupational standards specify a maximum allowable daily noise dose, expressed in percentages. For example, a person exposed to 85 dBA per NIOSH or 90 dBA per OSHA over an 8-hour work shift, will reach 100% of their daily noise dose.

May 03, 2016 · If at 88 dBA over 4 hours Time allowed is 4 hours: Dose = (Time at/Time allowed) = (4 hours at/ 4 hours allowed) = 1.0 (or 100%) But if the rest of the day, they continued to receive this noise exposure, they would have been at “88 dBA” for 8 hours: Dose = (8 hr exposed/4 hours allowed) = 2.0 This is a 200% dose… this requires control.

0.85 51 0.90 54 0.95 57 1.00 60: A total amount of hours may sometimes be confused as hours and minutes. For example, 7.45 hours could be mistaken to mean 7 hours and 45 minutes. Actually, those .45 hours when multiplied by 60 are converted to 27 minutes. Even easier is to use the above chart and as you can see .45 hours = 27 minutes. ...

Apr 06, 2016 · 86.99. 16. 80.00. 85.00. The noise exposure limit for a 12-hour shift using an exchange rate of 3dB and limit of 85 dB (A), based on the equal energy rule, is 83.24 dB (A). In other words, if the noise level is kept below 83 dB (A) then, according to equal energy concept, the maximum permissible limit is not exceeded.
