Recommended Noise Standards— Based on the recent ILO Code of Practice* the following standards and guidelines are provisionally recommended for attainment, as far as practicable: A warning limit value of 85 dB (A) may be set as the level below which very little risk to an unprotected ear, of hearing impairment exists for an eight hour exposure. The danger limit value shall be 90 dB (A), above which the danger of hearing impairment and deafness may result from an unprotected ear: Provided that during emergencies, or because of unforeseen technical reasons, a worker may be temporarily authorised to exceed the daily dose, but only if on the next day he recuperates so that the maximum weekly dose does not exceed the value specified above. A worker should not be allowed to enter, without appropriate ear protection, an area in which the noise level is 115 dB (A) or more. Personal protective equipment shall be worn, if there are single isolated outbursts of noise which can go above 130 dB (A) Impulse or 120 dB (A) ‘Fast’. No worker shall be allowed to enter an area where the noise level exceeds 140dB(A). ------------------------------------------------------------------------------------------------------------ FOR MINING CONTENT PLEASE FOLLOW US ON OUR SOCIAL MEDIA PLATFORM ➡️ Click here to join our Telegram group: https://t.me/Mining_Technical ↗️ Click here to join our Facebook page:   / miningtechnical   ↗️ Click here to join our Instagram:   / mining_technical   ↗️Click here to Join our Telegram Profile:   / technicalmining
