Noise

Noise is commonly identified as an occupational health hazard in many workplaces. Exposure to excessive levels of noise may lead to noise induced hearing loss (NIHL), or other auditory and/or non-auditory health effects.

深夜福利站’s Hearing Conservation Program

The purpose of 深夜福利站’s Hearing Conservation Program is to meet the requirements of Ontario's Regulation for Noise: .

This program is intended for all 深夜福利站 workers, students, contractors, and all other persons who may work in an environment considered hazardous to their hearing. This includes activities which may produce hazardous noise in research labs and classrooms.

In the Workplace, the Ontario Regulation 381/15, requires that employers ensure workers are not exposed to sound pressure levels greater than the equivalent sound exposure level limit of 85 dBA measured over an 8-hour workday.  This is commonly referred to as Lex,8.  深夜福利站 has adopted an action level limit of 80 dBA to investigate the potential for hazardous noise. 

Assessments

Noise assessments will be conducted by Health, Safety & Well-being in areas where the potential for hazardous noise has been identified.  If there is a concern about noise levels, the area supervisor should contact Health, Safety & Well-being, at hsw@uwo.ca to arrange for a site assessment.

Signage

深夜福利站 posts applicable signage in compliance with section 2(7) of O. Reg. 381/15 which states that “a clearly visible warning sign shall be posted at every approach to an area in the workplace where the sound level regularly exceeds 85 dBA.”

Training

0. Reg. 381/15 requires that workers provided with hearing protection must be trained on the care and use of the device, including its limitations, proper fitting, inspection and maintenance and, if applicable, the cleaning and disinfection of the device.

Health, Safety & Well-being has created an online module to provide the worker with general training and education on this topic. The Hearing Conservation module is available through 深夜福利站’s Human Resources. Visit the Required Training page under Required Training for Specific Duties.

A YouTube video is also available to demonstrate how to fit foam earplugs - 

Hearing Protection Devices

Health, Safety & Well-being carries a selection of Hearing Protection Devices (HPDs) for workers exposed to noise, provided when required, in compliance with Ontario Regulation 381/15.  These devices must comply with the CSA Standard Z94.2 “Hearing Protection Devices – performance, selection, care and use”.

A selection of ear plugs can be picked up and tried, so the most suitable one for the user can be selected. Earmuffs are also available for purchase at cost by the user department.

Music playing devices increase the risk of noise exposure and distraction in the workplace that interfere with the ability to receive important sounds.  Personal audio devices are not considered HPDs.  These types of devices shall not be used. 

Hearing Protection Devices is an information sheet that can be provided to supplement the training on HPDs.

Audiometric Screening

Audiometric screening is conducted by the Workplace Health Office. This service is offered to workers who may be exposed to excessive noise levels in the workplace, as identified through 深夜福利站’s completed by the immediate supervisor during the onboarding process.
