How the Hearing program works

How often do employees need to have a hearing test?
All employees in the Hearing Conservation Program must be tested annually as required by CFR 29 Part 1910.95 and ANSI S3.1-1991. Retests for any invalid test or STS (Standard Threshold Shifts) must be conducted within 30 days.

What type of testing does E&SSG conduct?
Air conduction, pure tone audiometric threshold tests will be conducted at 500hz, 1000hz, 2000hz, 3000hz, 4000hz, and 6000hz in each ear.

What type of testing equipment does E&SSG utilize?
E&SSG mobile units are equipped with today’s latest technology utilizing Tremetrics RA650 interface.

Who should be tested?
According to NIOSH, for maximum protection of the employees (and for that matter, the company), audiograms should be performed on the following five occasions: 
1. Pre-employment.
2. Prior to initial assignment in a hearing hazardous work area.
3. Annually as long as the employee is assigned to a noisy job (a time-weighted average exposure level equal to or greater than 85 dBA). 
4. At the time of reassignment out of a hearing hazardous job.
5. At the termination of employment.
*In addition, NIOSH suggests that employees who are not exposed be given periodic audiograms as part of the company's health care program. The audiograms of these employees can be compared to those of the exposed employees whenever the overall effectiveness of the hearing loss prevention program is evaluated.

What are the qualifications of E&SSG’s hearing technicians?
Testing completed by a CAOHC certified professional 

What is expected of our employees prior to testing?
Employees should not be exposed to loud noises for 14 hours at work or at home. The employer shall notify employees of the need to avoid high levels of non-occupational noise prior to testing. This can be accomplished by the use of hearing protection devices.

What should be expected the day of testing?
Our technician will arrive at least 30 minutes ahead of the scheduled start time to prepare and set up the unit for testing. Please determine ahead of time where we should park the mobile unit. We will require access to an electrical outlet. The technician will provide sign in sheets for the employees. It will help streamline the process if the employees have the form filled out prior to testing.
When should we expect to receive our final report?
Usually reports are finalized and delivered within a week of the final testing date. Data that is captured in the field will be sent to E&SSG's audiologist for review. Once the data has been reviewed and recommendations are logged, E&SSG will print the final results in a designated hearing report. The report will include a list of employees tested, individual audiograms, a list of potential STS and Recordable shifts or potential medical condition, a list of employees retested, a summary to help identify a possible trend in a particular area and individual employee notification letters are included. You will be contacted by an E&SSG client liaison to review the results, making sure all of your questions are answered.

Respiratory Fit Testing
We come to you


What OSHA Requires
OSHA requires all employees who wear a respirator be fit tested in order to ensure that the respirator fits properly.

The law requires that, if feasible, engineering controls shall be used to prevent air contamination at the workplace and reduce employee exposure below the Occupational Safety and Health Administration's (OSHA) Permissible Exposure Limits (PEL). When effective engineering controls are not feasible, the employer is required to provide an alternative method of employee protection such as providing an appropriate respirator for use by the employee. OSHA requires that employers shall ensure that employees using any respirator with a negative or positive pressure tight-fitting face piece pass an appropriate qualitative fit test (QLFT) or quantitative fit test (QNFT) prior to using a respirator and be fit tested with the same make, model, style, and size of respirator that will be used by the employee

If an employer chooses to implement the use of a respirator, OSHA requires that the employer has a written program in place. The written program should identify the following elements as applicable:

1.  Procedures for selecting respirators in the workplace.
2.  Medical Evaluations of employees required to use respirators.
3.  Fit Testing procedures for tight-fitting respirators.
4.  Procedures for proper use of respirators in routine and emergency situations.
5.  Procedures and schedules for cleaning and maintenance.
6.  Employee Education and Training 


Our View:  Onsite testing is convenient and cost effective. E&SSG uses mobile units equipped with today's latest technology to conduct respiratory fit testing. 

What We Offer
Mobile/Onsite Respiratory Fit Testing

E&SSG conducts quantitative respirator fit testing using a porta count machine. Employees will be fit tested using their own mask or an identical mask.

Each test takes about 10 minutes to complete with an average around 12 fit test an hour.
The following protocol is used by E&SSG in conducting fit testing on all employees:

1. The technician will provide the employee with the PLHCP recommendations prior to conducting the fit testing procedures.

i. E&SSG will not fit test any employee that has not passed a medical clearance. 

ii. The employer shall provide to E&SSG a copy of the medical clearance prior to requesting fit tests.

2. The technician will review with the employee how to put on a respirator, how it should be positioned on the face, how to set strap tension and how to determine an acceptable fit. This instruction may not constitute the employee's formal training on respirator use, because it is only a review.

3. The test shall not be conducted if there is any hair growth between the skin and the face piece sealing surface, such as stubble beard growth, beard, mustache or sideburns which cross the respirator sealing surface. Any type of apparel which interferes with a satisfactory fit shall be altered or removed.

4. If an employee exhibits difficulty in breathing during the tests, she or he shall be referred to a physician or other licensed health care professional, as appropriate, to determine whether the test subject can wear a respirator while performing her or his duties.

5. Exercise regimen. Prior to the commencement of the fit test, the employee shall be given a description of the fit test and the employee's responsibilities during the test procedure. The description of the process shall include a description of the test exercises that the employee will be performing. The respirator to be tested shall be worn for a few minutes before the start of the fit test.

6. The fit test shall be performed while the employee is wearing any applicable safety equipment that may be worn during actual respirator use which could interfere with respirator fit.

7. Instruct the employee to be tested to don the respirator for a few minutes before the fit test starts. This purges the ambient particles trapped inside the respirator and permits the wearer to make certain the respirator is comfortable. This individual shall already have been trained on how to wear the respirator properly.

8. A record of the test needs to be kept on file, assuming the fit test was successful. The record must contain the employee’s name; overall fit factor; make, model, style, and size of respirator used; and date tested.

Pulmonary Function Testing click here


Pulmonary Function Testing


Pulmonary Function Test (Spirometry)

Spirometry is the most basic and most frequently performed test to measure lung function; the ability to move air into and out of the lungs. Using an instrument called a spirometer, the test is performed while the patient breathes in and out as quickly as possible into a measurement device. Specific measurements from the individual's test are then compared to a standardized set of values, thus comparing the individual's lung function against a norm.

Spirometry in Occupational Medicine

Spirometry can be used in pre-placement and fit-for-duty examinations, in situations where: a) the physical demands of a job require a certain level of cardiopulmonary fitness; or b) the characteristics of respirator use can impose a significant burden on the cardiopulmonary systems. Though not required routinely under the OSHA Respiratory Protection Standard, spirometry may be used in the evaluation of respirator users in some situations.
Repeated spirometric evaluations can be used in medical surveillance programs when workplace exposures put workers at risk of developing occupationally related respiratory disorders. Surveillance is needed to detect the slowly developing or delayed losses of function that characterize many work-related respiratory disorders. Surveillance programs require that a baseline be established and that workers be retested periodically. These periodic spirometry tests may be mandated by OSHA regulations for employees exposed to asbestos, cadmium, coke oven emissions or cotton dust and for respirator-wearers exposed to benzene, formaldehyde or methylene chloride.

Respiratory Medical Clearance
Simply fill out the questionnaire and mail

OSHA requires the employer to provide a medical evaluation to determine the employee's ability to use a respirator before the employee is fit tested or required to use the respirator in the workplace. If an employer chooses to implement the use of a respirator, OSHA requires that the employer has a written program in place. ESSG will request a copy of your company's written program. The medical evaluation shall obtain the information requested by the questionnaire in Sections 1 and 2, Part A of Appendix C of OSHA regulation 29 CFR 1910.134. ESSG will provide the medical questionnaire to you to distribute to the participating employees. The employees will complete the questionnaires confidentially. The employee will be provided an envelope to seal the medical clearance form. This envelope will be returned to the company contact. The company contact will deliver all sealed envelopes to ESSG for review by our consulting physician. The employer will receive back from ESSG's consulting physician a written recommendation concerning the employee’s ability to use a respirator.​
