' Health and Safety Plan Operating <br />' Field operating Rrocedure - FldOl - MM FT—O-n CPION <br />' Noise is defined as unwanted soured. Noise can cause sudden traumatic hearing loss, <br /> long term more slowly o=irring sensory-neural hearing loss which is irreversible, <br /> disruption of c amuni.cation and masking of warning devices and alarms, increased <br />' stress levels and effects on the cardio-vascular and nervous systems. These latter <br /> two effects may occur at levels below that which cause damage to hearing and in <br /> situations where the conditions are more or less constant and daily. <br />' OaM regulations generally apply to 8 hxt e3gxxmres arra consider 85 dBA as an action <br /> level for a Hearing CbnseYvation Program. <br />' Ffiere feasible, noise exposure will be ca ntrolled by engineering controls. Where <br /> high noise levels are encountered and where engineering controls are infeasible or <br /> until engineering controls can be aooanpl fished, hearing protection devices will be <br />' used for worker protection from noise induced hearing loss. <br /> Some of the sources of noise can hazardous materials, cion and industrial <br /> sites of a magnitude to cause hearing damage are: ompres_sor motors, drill rig <br /> engine, haunee r blows (frau split spoon or other), corpressor motors, cXXIrprassed air, <br /> oanpressed water, and heavy equipment. The list is not all inclusive. <br /> Any sound level surveys indicating noise levels of 85 dBA or above, or, in the <br /> absence of sound level measuring instramentatian, any noise/sound preventing normal <br /> vocal discission between two individuals at arms length distance will dictate the <br /> need for hearing protection. <br /> Hearing protection will be afforded by either disposable ear plugs or ear muffs. <br />' Administrative time control is not an acceptable method for preventing noise exposure <br /> since extreme noise for a short duration can cause severe, permanent hearing loss. <br />' In addition to these protocols, WEST I s Hearing Conservation Program includes <br /> physical exaM nation and audiometric testing during wwaal medical mxdtoring. <br /> Zhe selection, use, maintenance and control of hearing protection is further defined <br /> in the WESICN Personnel Protective Equipment Program. <br /> 1 <br />
