The earplugs should be free of debris, Helix tears, and other physical damage. Tip • Inspect the coiled cable and the cable connection to the earplug. Left Earplug Right Earplug • Lubricate the earplugs with water or Aegisound Ear Gel around the canal tip, being careful not to allow water or gel into the opening at the earplug tip. • Gently insert the tip of the earplug into the ear canal with the helix rotated forward. • Rotate the earplug backwards while pushing the earplug until the tip slides into the canal and the helix fits into the pocket at the top of the ear. Correct Earplug Insertion Correct Incorrect Insertion Insertion (Earplug (Earplug not locked locked in in helix) helix) Custom Earplug Familiarization • Wearing the custom earplugs for long periods of time may require an adjustment period of a week or more. • Begin by wearing earplugs for one hour at a time for the first several days. • Once acclimated to the earplugs, start wearing them for two or more hours until they can be worn for an entire shift. Do not risk exposure to noise without wearing hearing protection. USER MANUAL | 3 Typical Earplug Insertion The following indicates the most typical insertion technique. All ears are different, and techniques may need to vary from that shown. It will be helpful to practice by using a mirror until comfortable with installing the earplugs into the correct position. 1. Insert the tip into the ear canal with the helix rotated forward 2. While pressing the tip into the ear canal, rotate the helix back. Pulling on the outer ear in directions indicated (orange) may help the earplug to slide into position 3. Continue rotating back until the earplug helix can be inserted into the helix of the ear. The earplug to the right is not yet fully inserted. 4. Press on the earplug to be sure it is seated fully into the ear helix and the outer ear bowl. 4 | DANR THP & THPC EARPLUGS Waxguard Replacement Installed waxguards should be inspected before each use to verify that they are not blocked with wax or other debris. If a waxguard becomes obstructed, it should be removed and replaced. To remove the waxguard, insert the “OLD” side of the waxguard applicator into the used waxguard installed in the tip of the DANR earplug. When the waxguard applicator is removed from the earplug, the old waxguard will be captured by the applicator. A new waxguard will come preinstalled on the “NEW” end of the waxguard applicator. The new waxguard should be installed into the tip of the earplug using a similar motion used in the removal step. When the waxguard applicator is removed from the earplug, the new waxguard will remain installed in the earplug. Waxguards should only be changed in sheltered and clean areas. Waxguards should be disposed of properly. Replacement Parts To reorder, please contact Gentex Corporation at (603) 657-1200 DANR Replacement Parts Please refer to the following part numbers when ordering: Part Number Description 05-021001 DANR Earplug Set T1P 05-021008 Replacement Waxguards with Applicator 05-999002 Aegisound® Ear Gel Note: Please provide the earplug serial number, person’s name, and their last 4 of SSN when reordering earplugs. USER MANUAL | 5 Warning Do not turn the DANR system on unless the DANR earplugs are connected to the earcups and properly inserted into the ears to obtain proper initialization. Earplugs are custom made to fit your ear. They will not work for anyone else’s ear. Attempting to use custom earplugs that are not the wearer’s own, may result in damage to the ear canal. Always wear both the headset and the earplugs when in high noise environments. Never remove the earplugs while in a high noise environment. Failure to comply with general safety precautions violates the safety intent of this product and may result in damage to the product or bodily harm. Gentex Corportion claims no liability for damage or injury resulting from a failure to comply with the safety precautions outlined in this manual. Do not wrap the coiled cable around your neck. Doing so can cause strangulation. See supplemental component manuals for additional warnings and cautionary statements 6 | DANR THP & THPC EARPLUGS Caution Inserting or removing the earplugs too quickly may result in air pressure or suction against the eardrum causing temporary pain. Earplugs should be inserted or removed slowly with a twisting motion to prevent excess pressure buildup. Gently moving the earplug while opening the jaw fully may remove excess pressure buildup. Prolonged use of the earplugs (exceeding several hours) may result in temporary soreness near the ear canal. Use of Aegisound custom earplugs may reduce the risk of this irritation when compared to expandable foam type plugs. The use of earplugs may require a “break-in” period to accustom the ear canal to the presence of the earplug. In order to ensure maximum performance, the ear canal should be clean and free of excess ear wax and debris before inserting the earplugs. Long term usage of earplugs could result in the buildup of ear wax within the ear. In the event that ear wax or debris becomes impacted in your ear canal, seek medical consultation. When not in use, store the earplugs in a clean and dye free location, preferably in their case. Surfaces that have been dyed should be avoided to prevent the possibility of having the dye transfer onto the earplugs. The earplug surfaces should remain clean and free of other contaminates that could cause irritation of the ear canal such as sand and grit. Earplugs should be cleaned periodically with warm, soapy water to prevent buildup of dirt and bacteria. (NOTE: Do NOT submerge or allow water to enter the sound port in the tip of the canal.) Ear inflammation, otitis externa, or other infection could result from the use of dirty earplugs. In the event of pain or discharge from the ear canal, seek medical consultation. DANR custom earplugs are made from an immunologically inert material, and allergic reactions would be rare. In the event an allergic reaction is suspected, discontinue use and seek medical consultation. Do not hang or swing the headset by the earplugs or the cable. The cable may detach, damaging the devices.

  • Personal Hearing Protection Devices ______
    Safe Operating Procedure (Revised 10/14) PERSONAL HEARING PROTECTION DEVICES _____________________________________________________________________ When employees are exposed to sound levels in excess of occupational exposure or action limits, the first course of action is to reduce the noise with source and pathway controls (engineering controls). When sound levels cannot be reduced to less than an 8-hour Time Weighted Average (TWA) of 85 dBA through source and pathway control(s) and/or receiver controls (administrative controls), hearing protection should be used to protect workers from work-related hearing loss. Choosing the right kind of hearing protective device and correct use are essential to protection from hazardous noise exposures. This SOP describes the most common types of hearing protectors used at UNL. There may be specialty hearing protectors prescribed for certain UNL employees exposed to impulse noises which are not addressed in this SOP. Regardless, all employees participating in UNL’s Hearing Conservation Program will receive instruction in proper use of the hearing protectors prescribed for their exposure situation. Types of Hearing Protection There are two main types of hearing protection devices: ear plugs and ear muffs. Ear Plugs Ear plugs (figure 1) are commonly available in the following styles: roll-down foam; pre-molded; and semi-insert. Roll-down foam earplugs are rolled before each use and inserted into the ear canals. They conform to the shape of individual’s ear canals. One size of roll-down foam will fit most workers although workers with extremely small or large ear canals may need a different size. One disadvantage of roll-down foam ear plugs is that workers need to roll them each time they wear them, thus making it harder to use if workers have to take ear plugs out frequently during a work shift.

  • Honeywell Howard Leight Arc Flash Protection Brochure
    SOUNDSOURCE™ NO. 7-NA-US Arc Flash Protection What requirements must a hearing protector meet for arc flash protection? Arc flash is the term describing an extremely dangerous electrical hazard when uncontrolled current passes through the air between two conductors. When voltage is high enough (over 480V), the intense heat of the arc flash can create a serious hazard for workers in the arc flash zone; temperatures can reach 35,000° F, and the impulse sound resulting from the explosive expansion from the arc can exceed 160 dB peak. Shrapnel from an arc blast can be propelled over 700 mph. Each year, more than 2,000 persons are treated for arc flash burns (NFPA 70E-2015, Annex K). The National Fire Protection Association publishes its NFPA 70E Standard for Electrical Safety in the Workplace1, which defines arc flash boundary zones, and recommended PPE (personal protective equipment) for each zone. The FAQs on the next page summarize the requirements for hearing protection defined in NFPA 70E-2015. Are hearing protectors required for arc flash hazard zones, according to NFPA 70E ? References: Yes, the 2015 standard requires workers in an arc flash hazard zone to wear insert-type 1. National Fire Protection hearing protection (earplugs), as defined in Section 130.7(C)(5)). Association, NFPA 70E®: Standard for Electrical Safety Does NFPA certify or approve particular hearing protectors as being compliant with in the Workplace®, NFPA 70E-2015? No, the NFPA does not certify or approve any PPE. Any manufacturer 2015 edition. claims that a particular piece of PPE has been tested to NFPA standards, or has been 2.

  • Measurements of Earplug Attenuation Under Supra-Aural and Circumaural Headphones
    International Journal of Audiology 2012; 51: 730–738 Original Article Measurements of earplug attenuation under supra-aural and circumaural headphones Jennifer B. Tufts* , Jillian V. Palmer * & Lynne Marshall† *Department of Communication Sciences, University of Connecticut, Storrs, USA, and †Naval Submarine Medical Research Laboratory, Groton, Connecticut, USA Abstract Objective: Supra-aural audiometric headphones are generally not recommended for use in measuring the attenuation of earplugs, because contact between the headphone and pinna and/or earplug could alter the attenuation obtained, and because of concerns of non-comparability between modes of excitation from supra-aural headphones and the sound-fi eld procedure required by the standardized method. In this study, we compared measurements of earplug attenuation obtained under Telephonics TDH-50P supra-aural headphones with measurements obtained under circumaural headphones designed expressly for such testing. Design: The attenuation of three types of earplugs (foam, premolded quadruple-fl ange, and custom-molded) was measured in a repeated-measures design. Study sample: The study sample comprised 42 normal-hearing adults (21 females, 21 males). Results: With the foam earplugs, nearly all of the attenuation measurements under the supra-aural headphones fell within 10 dB of the measurements under the circumaural headphones. With the fl ange and custom earplugs, approximately 10% of individuals obtained spuriously high attenuation under the supra-aural headphones. Conclusions: We conclude that standard supra-aural audiometric headphones are suitable for measuring the attenuation provided by foam earplugs. However, supra-aural headphones should not be used to measure the attenuation of fl ange or custom-molded earplugs. The potential exists for substantial over-estimation of attenuation, especially of custom plugs.

  • Sound Advice on Hearing Protection for Young Ears
    ® http://www.noisyplanet.nidcd.nih.gov Sound Advice on Hearing Protection for Young Ears Noise-induced hearing loss (NIHL) occurs when tiny sensory cells in our inner ear, called hair cells, are damaged by sounds that are too loud and that last too long. How near we are to the source of the noise also matters. NIHL can be permanent—but it is preventable. You can help your tween enjoy healthy hearing for a lifetime by learning about hearing protectors and when to use them. When are hearing protectors recommended? Hearing protectors are recommended whenever a person’s hearing is exposed to noise levels that exceed a certain level and time. Scientists have set this level in the workplace at 85 decibels for exposures longer than eight continuous hours. The louder the sound, the shorter the time before damage can occur. In practical terms, your child won’t damage his or her hearing by temporarily cranking up the volume for a favorite song or by taking a short ride on the subway. On the other hand, your tween could potentially damage his or her hearing by listening to music at maximum volume for an extended period of time. The same is true when your tween participates in any activity that exceeds a safe noise level and listening time. Your child should wear hearing protectors while using a lawn mower, operating many power tools, or riding a snowmobile or farm tractor. Hearing protectors may also be advisable when your tween attends certain events in stadiums, gymnasiums, amusement parks, auditoriums, and other entertainment venues.

Before Usage Always evaluate the adequacy of your protective gear before entering hazardous environments. The wearer should ensure that: • The earmuffs and earplugs are fitted, adjusted, and maintained in accordance with the manufacturer’s instructions. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the included instructions for proper fit. • The earmuffs and earplugs have been inspected for serviceability. • The earmuffs and earplugs are worn at all times in noisy surroundings. The use of any hearing protective device will not guarantee adequate protection for hearing loss for all persons under all circumstances. Consult your physician or audiologist frequently when being exposed to high noise levels. If exposure to high noise levels occurs during employment activities, also consult your employer regularly. US Federal Law requires the following additional statements: The level of noise entering a person’s ear, when hearing protector is worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the Noise Reduction Rating (NRR).

    11 PERSONAL MEASURES AND HEARING CONSERVATION Professor Samir N.Y. Gerges Federal University of Santa Catarina Mechanical Engineering Department-Noise and Vibration Laboratory Cx.P.476 - Florianópolis - SC BRAZIL [email protected] Mr L. Vedsmand Mr H. Lester* Consultant, Work Environment Health and Safety Executive, UK BAT-Kartellet, Kampmannsgade 4 Postboks 392 DK-1790 Copenhagen DENMARK [email protected] 11.1. WORK PRACTICES AND ADMINISTRATIVE CONTROLS Evaluation of the workplace for noise exposure includes preliminary noise measurements, separation of the workplace into different noise risk areas - and development of both short and long term noise management plans. After evaluation of the workplace, it might be appropriate to evaluate possibilities which the individual employee has to control his or her own (noise) work environment and to evaluate simple measures which may result in a further reduction of the noise level. Whatever noise levels are agreed upon in the workplace, or have been legally demanded, there will always for the individual employee and for a specific group of employees in definite sections of the workplace be a question of what risk is acceptable - or "the acceptability of the noise level in the work environment". Every human has their own limit of acceptance - according to their attitude to their own life and health, their family and their colleaques. This limit of acceptance varies a lot from human to human, but even if the limit is exceeded one will back away from the risk. The limit is rather vague and is related to workers’ traditions, possibilities of finding other less unhealthy jobs and the degree of influence at the workplace.
