Operating Precautions - rcf DS313 Manual De Uso Y De Instalación

Hearing loss - Exposure to high sound levels can cause permanent hearing loss. The sound
pressure level which leads to hearing loss varies considerably from one person to another, and
depends on the duration of exposure. The U.S. Government's Occupational Safety and Healt
Administration (OSHA) has established the maximum sound pressure levels that can be with-
stood without causing damage, which are shown in the table below. According to the OSHA regula-
tions, any exposure over the maximum limits indicated in the table can reduce the hearing capacity of
a person. To prevent potentially dangerous exposure to high sound pressure levels, anyone subjected
to such levels must use suitable protection. When an RCF product capable of producing high sound
levels is being used, it is therefore necessary to wear ear plugs or protective earphones when the limits
shown in the table are exceeded.
