2 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT an effective hearing conservation program An effective hearing conservation program can prevent hearing loss, improve employee morale and a general feeling of well being, increase quality of production, and reduce the incidence id of stress related ltd disease. 2

3 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT an effective hearing conservation program Employer Responsibilities The employer must administer a continuing, effective hearing conservation program whenever employee noise exposures are at or above an eight hour timeweighted average (TWA) of 85 dba or, equivalently, or a dose of 50 percent. This is referred to as the action Minimum requirements of a hearingconservation program Program Monitoring Audiometric Testing Hearing Protection Devices (HPD) Employee Training and Education Recordkeeping level. Recordkeeping 3

4 Monitoring Program CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT The employer must develop and implement a monitoring program whenever information indicates that any employee's exposure may equal or exceed the action level. The sampling strategy must be designed to identify all employees for inclusion in the hearing conservation program, and enable the proper selection of hearing protectors. 4

5 Monitoring Program part 2 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT The monitoring requirement is performance based, as it allows employers to choose a monitoring method that best suits each individual work situation. Either personal or area monitoring may be used. If there are circumstances that may make area monitoring generally inappropriate, such as high worker mobility, significant variations in sound level or a significant component of impulse noise, then the employer must use representative personal sampling unless it can be shown thatarea area sampling produces equivalent results 5

6 Monitoring Program part 3 Noise measurements must integrate all continuous, intermittent, and impulsive noise levels from 80 to 130 dba. 6 CANUTILLO INDEPENDENT SCHOOL DISTRICT Es tablished in as The Lone Star School & In 1959 as Canutillo

7 Monitoring Program Part4 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT Repeated Monitoring. Monitoring must be repeated whenever a changein production, process, equipment orcontrols increases noise exposures to the extent that: Additional employees may be exposed at or above the action level, or The attenuation provided by hearing protectors used by employees may be rendered dinadequate to meet the requirements described din Hearing Protection Devices. Employee Notification. The employer must notify each employee who is exposed at or above the action level of the results of the monitoring. Observation of Monitoring. The employer must provide affected employees or their representatives with an opportunity to observe noise monitoring procedures. Refer to the Exposure Evaluation section for additional information on noise monitoring. 7

8 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT Hearing Protection Devices (HPDs) Hearing protection devices (HPDs) are considered the last option to control exposures to noise. HPDs aregenerally used during the necessary time it takes to implement engineering or administrative controls, or when such controls are not feasible. Basic Requirements: Employers must make HPDs available to all employees exposed at or above the action level. These must be provided at no cost to employees and must be replaced as necessary. Employers must ensure that HPDs are worn by employees: where feasible administrative and engineering controls fail to reduce sound levels within those listed in Table G 16. or who are exposed at or above the action level and who have not yet had a baseline audiogram established or have experienced a standard threshold shift (STS). HPD Selection and Use Employees must be given the opportunity to select their HPDs from a suitable variety. Generally, this should include a minimum of two devices, representative of at least two different types. The employer must provide training in the use and care of all HPDs provided to employees. 8

9 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT Hearing Protection Devices (HPDs) Part 2 The employer must ensure proper initial fitting of HPDs and supervise their correct use. HPD Attenuation Attenuation refers to the damping or decrease of noise levels as a result of wearing HPDs. The employer must evaluate HPD attenuation for the specific noise environments in which the HPD will be used. HPDs must attenuate employee exposure to at least an eight hour time weighted average of 90 dba. For employees who have experienced a standard threshold shift (STS), HPDs must attenuate exposure at or below the action level of 85 dba TWA (time weighted average). The adequacy of the HPDs must be re evaluated whenever employee noise exposures increase to the extent that they may no longer provide adequate attenuation. The employer must provide more effective hearing protectors asnecessary necessary. Methods for Estimating HPD Attenuation (App IV:C) Hearing Protection Labeling Additional Information(App IV:D) on the background of hearing protection labeling, Task Force recommended changes, and other relevant publications are available. 9

10 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT Employee Training and Education The employer must: institute a training program for all employees with noise exposures at or above the action level and ensure employee participation; repeat training annually for each employee in the hearing conservation program; update information to be consistent with changes in protective equipment and work processes; ensure that each employee is informed of the following: The effects of noise on hearing The purpose p of hearing protectors, the advantages, disadvantages, and attenuation of various types, and instructions on selection, fitting, use, and care. The purpose of audiometric testing and an explanation of test procedures. 10

11 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT Access to Information and Training Materials The employer must: Make copies of the noise standard available to affected employees or their representatives and post a copy in the workplace. Provide affected employees with any informational materials pertaining to the standard that are supplied to the employer by OSHA. Provide, upon request, all material relating to the employer's training and education program to OSHA. 11

12 Recordkeeping CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT The purpose of OSHA recordkeeping regulations is to assist employers in recognizing and correcting workplace hazardsby tracking work related related injuries/illnesses and their causes. Requirements according to the noise standard are: Exposure Measurements Employers must maintain anaccuraterecord accurate record ofall employee exposure measurements These records must be retained for two years. Audiometric Test Records The employer must retain all employee audiometric test records. These records must include: Name and job classification of the employee. Date of the audiogram. The examiner's name. Date of the last acoustic or exhaustive calibration of the audiometer. Employee's most recent noise exposure assessment. The employer must maintain accurate records of the background sound pressure level measurements in audiometric test rooms. These records must be maintained for the duration of the affected worker's employment. 12

13 Recordkeeping Part 2 CANU UTILLO IN NDEPENDE ENT SCHO OOL DIST TRICT Access to Records All records required by the noise standard must be provided upon request to: employees, former employees, representatives designated by the individual employee, and OSHA. Transfer of Records Employers who cease to do business must transfer to the successor employer all records required by the noise standard. The successor employer must retain these records for the remainder of the periods described previously. With regard to recordkeeping requirements, OSHA has developed a "decision tree to determine whether the results of an audiometric exam given on or after January 1, 2003 reveal a recordable STS. 13
