Engineering and Admin Controls- hierarchy of controls - list and explain, cite

Hierarchy of controls: from most to least effective: elimination (remove the noise), substitution (replace the source of the noise), engineering controls (isolate people from the noise), administrative controls (change the way people work), and personal protective equipment (protect people).

Engineering and Admin Controls - (6, 7) spacing

HPD - (8) spacing

TWA / HPD / MSHA - Make sure abbreviations were throughout page.

Says: "If the employee feels that hearing protection may impinge his/her work, whether it be missing important warning signals or the ability to communicate, he/she is less likely to wear it." - Change to: If the employee feels that hearing protection may impinge the ability to work (missing important warning signals or the ability to communicate), they are less likely to wear it. (using "employee" instead of his/her to improve readability)

HCP needs introducing or to not be an abbreviation

Sound survey- A sound survey is often completed to determine areas of potential high noise exposure. A noise screening is completed initially to determine which areas are higher than 80 dB A. For these areas, an official sound survey will take place.[3] This type of survey is normally completed using a sound level meter (SLM) suggest linking this to the SLM wikipedia page. There are three types of sound level meters. Type 0 is precision instrument normally used in laboratories '''. A type''' Type 1 is for precision measurements taken in the field.

Section - Completing baseline audiograms and periodically monitoring threshold levels is one way to track any changes in hearing and identify if there is a need to make improvements to the  HCP . The Occupational Safety and Health Administration (OSHA), which monitors workplaces in the United states to ensure safe and healthful working conditions, specifies that employees should have a baseline audiogram established within 6 months of their first exposure to 85 dBA time-weighted average (TWA). If a worker is unable to obtain a baseline audiogram within 6 months of employment, hearing protection devices (HPD ) is required to be worn if the worker is exposed to 85 dBA or above TWA. HPD must be worn until a baseline audiogram is obtained .[17]

Under  the Mine Safety and Health Administration  (MSHA), which monitors compliance to standards within the mining industry, an existing audiogram that meets specific standards can be used for the employee’s baseline.

Section 1: Program Requirements - (need a source)

Section: Employee Training and Education - Providing a refresher training when appropriate will support retention of this information  as well . OSHA requires  said this training to be completed on an annual basis. Proper training is imperative since "even with a very modest amount of instruction attenuation performance can be significantly improved."

Section: Program Evaluation - Proper program evaluation is important in maintaining the health of hearing conservation program. The National Institute for Occupational Safety and Health (NIOSH) has created a checklist to help evaluate the effectiveness of a hearing conservation program. It can be found on their website. *link? NIOSH recommends that fewer than 5% of exposed employees should have a 15 dB  Significant Threshold Shift significant threshold shift in the same ear and same frequency.

MSHA defines a  standard threshold shift STS as an average decrease in auditory sensitivity of 10 dB HL at the frequencies  2,000, 3,000, and 4,000 2000, 3000, and 4000 Hz. (30 CFR Part 62).
