J <br /> rieal,th and Safety Plan operating Procedures <br /> Field operating Procedure - Fldol - NOISE pFMSCI <br /> Noise is defined as unwanted Noise can cause sudden traumatic, hearing loss, <br /> long term more sloTaly occurring sensory-neural hearing loss which is irreversible, <br /> disruption of ccesmiunication and masking of warning devices and alarms, increased <br /> stress levels and effects on the cardio-vasc-ular and nervous systems. These latter <br /> two effects nay occur at levels below that which cause damage to wring and in <br /> situations where the conditions are more or less constant and daily. <br /> OSHA regulations generally apply to 8 hour exposur'e_., and consider 85 dBA as an action <br /> level for a Hearing Conservation Program. <br /> Where feasible, noise exposure will be controlled by engineering controls. 'Where <br /> high noise levels are encountered and where engineering controls are infeasible or <br /> until engineeritxg controls can be accoMlished, hearing protection devices will be <br /> used for worker protection from noise induced hearing loss. <br /> Some of the sources of noise on hazardous materials,� ion and irxlustrial <br /> sites of a magnitude to cause hearing damageresscr motors, drill rig <br /> engine, hammer blows (from split spoon or other) , compressor motors, compressed air, <br /> compressed water, and heavy equignent. 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 instramentation, any noise/sound preventing normal <br /> vocal discussion between two individuals at arm 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 preventingnoise exposure los <br /> since extreme noise for a short duration can cause severe, permanent <br /> s. <br /> In addition to these protocols, WE5,w's Hearing Conservation Program includes <br /> physical exairination and audiometric testing during annual medical monitoring. <br /> The selection, use, maintenance and control of hearing protection is further defined <br /> in the 'WESTM personnel Protective Fquipme<nt Prcg'�. <br />
