5 WHAT IS A CODE OF PRACTICE? WSCC codes of practice provide practical guidance to achieve the safety requirements of the Northwest Territories and Nunavut Safety Acts and related Regulations. As per subsection 18(3) of the Northwest Territories and Nunavut Safety Acts, For the purpose of providing practical guidance with respect to the requirements of any provision of this Act or the regulations, the Chief Safety Office may approve and issue such codes of practice as he or she considers are suitable for that purpose. WSCC codes of practice apply to workplaces in the Northwest Territories and Nunavut. The Chief Safety Officer approves codes of practice for use by all occupational health and safety (OHS) stakeholders. Codes of practice come into effect in each territory on the day they are published in the Northwest Territories Gazette and Nunavut Gazette. Codes of practice do not have the same legal force as the Safety Acts and related regulations. A person or employer cannot face prosecution for failing to comply with a code of practice. However, in legal proceedings under the Safety Acts and related Regulations, failure to observe a code of practice may be a consideration when determining whether a worker or employer complies with the Safety Acts and related Regulations. Employers and workers should follow WSCC codes of practice unless there is an alternative course of action that achieves the same or better occupational health and safety outcomes. Provides practical guidelines. Adapts to individual work sites. May serve as evidence. Should be followed unless there s a better way. 5 Code of Practice Personal Protective Equipment Hearing Protection

INTRODUCTION This Hearing Protection code of practice provides basic guidelines to ensure worker safety in the workplace through the use of personal protective equipment (PPE).

6 INTRODUCTION This Hearing Protection code of practice provides basic guidelines to ensure worker safety in the workplace through the use of personal protective equipment (PPE). If workers are at risk for hearing damage in the workplace, the regulations require that adequate measures be taken and workers wear hearing protective equipment to protect them from noise hazards. Definition Personal Protective Equipment means any clothing, device or other article that is intended to be worn or used by a worker to prevent injury or to facilitate rescue Interpretation 111. In this Part, "dba Lex" means the level of a worker s total exposure to noise in dba, averaged over an entire workday and adjusted to an equivalent eight-hour exposure. (dba Lex) Noise is one of the most common workplace hazards. Exposure to excessive noise can damage hearing and impact worker health and safety. The body responds to noise in similar way as to stress, affecting blood pressure, heart rate, hormone levels, and blood cholesterol. Too much noise can make a person feel tired. Hearing loss is permanent. Furthermore, high noise levels interfere with hearing messages and can lead to unsafe situations. Work-related hearing loss is preventable. PPE is equipment worn by workers to minimize exposure to specific occupational hazards such as noise. PPE cannot eliminate the hazard, but can reduce the risk of injury. 6 Code of Practice Personal Protective Equipment Hearing Protection

7 PPE AND HAZARD CONTROL Decisions about PPE form part of the hazard assessment process, the standard work site approach to dealing with potential hazards. There are five basic ways to control hazards. These controls form a hierarchy. Elimination is always the first control to consider. After that proceed down the hierarchy until the control of last resort, PPE. 1. Elimination (remove from the work site) 2. Substitution (replace noisy equipment or machinery with less noisy machinery) 3. Engineering (modify operation to generate less noise: e.g. lubrication, speed, dampeners.) 4. Administration (modify circumstances of exposure: e.g. change production schedule) 5. Personal Protective Equipment (provide earmuffs/earplugs) PPE is not the first protection option. The use of PPE does not prevent accidents or eliminate hazards. Make every effort to control all hazards at the source. When reducing noise exposure, preference is given to engineering controls, then administrative controls. If this is not possible, PPE in the form of hearing protectors reduce the amount of noise reaching the ears. PPE cannot achieve its full-protection potential without worker knowledge and cooperation. Several controls may have to be put in place. Certain hazards may require multiple PPE solutions. For example, working near machinery on the road could require a hard hat, ear muffs, goggles and high-visibility safety apparel. Wearing PPE should not add to the hazard or create a new hazard. Using several types of protection at the same time i.e. hard hat, ear muffs and goggles, should not increase the risk to the worker. PPE design criteria cannot cover all eventualities. Do not use PPE when its usage creates hazards greater than those for which it is designed. Take uncertainties into account when evaluating potential hazards.

10 CSA STANDARDS The Canadian Standards Association develops standards to address needs such as enhancing health and safety. To view CSA standards online see CSA Group test and certify products to Canadian standards and issue the CSA Mark for qualified products. Refer to CSA Standard Z , Hearing Protection Devices Performance, Selection, Care and Use. In the Occupational Health and Safety Regulations a CSA reference is written as follows: Identifying Mark of Approved Equipment Safety Acts Occupational Health and Safety Regulations Northwest Territories and Nunavut 23. (1) This section applies in respect of equipment and personal protective equipment that is required by these regulations to be approved by an agency. (2) An employer or supplier shall ensure that the approval of equipment and personal protective equipment by an agency is evidenced by a seal, stamp, logo or similar identifying mark of the agency indicating such approval, affixed on (a) the equipment or personal protective equipment; or (b) the packaging accompanying the equipment or personal protective equipment. 10 Code of Practice Personal Protective Equipment Hearing Protection

11 CAN/CSA-Z CAN/CSA Stands for Canada and the Canadian Standards Association. Z94.2 Lettering between CAN/CSA and the last two digits represent the internal CSA coding of the relevant standard. In this case the coding refers to the standard on Hearing Protection Devices. -94 The last two digits indicate the year issued. Technological and research developments result in regular updates to standards. The end of the CSA reference changes to the year of the update. The current standard for Hearing Protectors is Z Hearing Protection Devices - Performance, Selection, Care, and Use. This becomes the standard that applies to the regulation. MAKE SURE YOU USE THE MOST UP-TO-DATE STANDARD. 11 Code of Practice Personal Protective Equipment Hearing Protection

12 GENERAL INFORMATION People should wear a hearing protector if the noise or sound level at the workplace exceeds 85 decibels (A-weighted) or db(a). Hearing protectors reduce the noise exposure level and the risk of hearing loss. If hearing protection is required, then a complete hearing conservation program should be instituted. A hearing conservation program includes noise assessment, hearing protector selection, employee training and education, audiometric testing, maintenance, inspection, record keeping, and program evaluation. The effectiveness of hearing protection is reduced greatly if the hearing protectors do not fit properly or if they are worn only part time during periods of noise exposure. To maintain their effectiveness, they should not be modified. Radio headsets are not substitutes for hearing protectors and should not be worn where hearing protectors are required to protect against exposure to noise. Ear plugs are inserted to block the ear canal. They may be premolded (preformed) or moldable (foam ear plugs). Ear plugs are sold as disposable products or reusable plugs. Custom molded ear plugs are also available. Semi-insert ear plugs which consist of two ear plugs held over the ends of the ear canal by a rigid headband. Ear muffs consist of sound-attenuating material and soft ear cushions that fit around the ear and hard outer cups. They are held together by a head band. For more information on occupational noise levels and hearing protection see: Occupational Noise Levels: pdf Foam Earplug Fit: 12 Code of Practice Personal Protective Equipment Hearing Protection

13 SELECTION The choice of hearing protectors is a very personal one and depends on a number of factors including level of noise, comfort, and the suitability of the hearing protector for both the worker and his environment. Most importantly, the hearing protector should provide the desired noise reduction. It is best, where protectors must be used, to provide a choice of a number of different types to choose from. If the noise exposure is intermittent, ear muffs are more desirable, since it may be inconvenient to remove and reinsert earplugs. Manufacturers provide information about the noise reducing capability of a hearing protector as an NRR (noise reduction rating) number. The NRR ratings are based on noise reduction obtained in laboratory conditions. Select hearing protection that is: Correct for the job. Refer to the Canadian Standards Association (CSA) Standard Z or contact WSCC for more information. Provides adequate protection. Check the manufacturer's literature. Comfortable enough to be accepted and worn.

14 MAINENANCE Follow the manufacturer's instructions. Check hearing protection regularly for wear and tear. Replace ear cushions or plugs that are no longer pliable. Disassemble ear muffs to clean. Wash ear muffs with a mild liquid detergent in warm water, and then rinse in clear warm water. Ensure that sound-attenuating material inside the ear cushions does not get wet. Use a soft brush to remove skin oil and dirt that can harden ear cushions. Replace a unit when head bands are so stretched that they do not keep ear cushions snugly against the head.
