3.2.4 Confined Space Entry <br /> It is not anticipated that any work conducted during this project will require entry into a <br /> confined space. A confined space is defined as an enclosure which is large enough for an <br /> employee to enter, but which has limited means of access and egress and is not designed for <br /> continuous employee occupancy. <br /> A permit-required confined space is a confined space as defined above winch also contains <br /> one or more health and/or safety hazards. This can include chemical, mechanical, electrical, <br /> or other hazards. The potential for a hazardous atmosphere is also present. <br /> 3.2.5 Noise <br /> Some of the equipment used on the project generates loud noise Exposure to sound levels <br /> above 85 dBA can cause temporary impairment of hearing Prolonged and repeated exposure <br /> to sound levels above 85 dBA can cause permanent hearing damage The risk and seventy of <br /> hearing loss increases with the intensity and duration of the exposure In addition to <br /> damaging hearing, noise can impair voice communication, thereby increasing the risk of <br /> incidents. <br /> M7,(05-09-9WSTR440063 bk 3-3 <br />
