ADOSH-SF Code of Practice CoP 3.0 Occupational Noise, Version 4.0, dated 15 July 2024, sets the mandatory occupational noise requirements applying to employers within the Emirate of Abu Dhabi. It sits within the Codes of Practice layer of ADOSH-SF, which ADPHC describes as providing minimum mandatory occupational safety and health technical requirements for all entities regardless of risk classification.\n\nThe Code addresses the management of occupational noise from initial risk assessment through monitoring, control, hearing conservation, audiometric testing, training and record retention. Its structure places responsibility on the employer to identify exposure, assess risk, introduce controls and verify that the arrangements remain effective.\n\nCoP 3.0 is an Abu Dhabi instrument. It must not be described as federal UAE law or as automatically applicable in Dubai or the other emirates. No equivalent published occupational noise requirement has been identified for those jurisdictions or at federal level.
CoP 3.0 applies to all employers within the Emirate of Abu Dhabi. Its subject is occupational noise: sound arising from or encountered during work that may affect employees and other people entering controlled work areas.
The employer carries the principal responsibility for compliance. This includes arranging a suitable risk assessment, identifying exposed groups, obtaining measurements where required, establishing controls and maintaining a hearing conservation programme where the action level is reached.
The employer must also provide suitable information, instruction and training. Where exposure reaches an eight-hour time-weighted average of 85 dB(A), CoP 3.0 requires training within 30 days of starting work and before the employee enters a high-noise area. This figure and the related duty come from CoP 3.0 and apply within the Emirate of Abu Dhabi.
In practice, employees contribute by following established controls, using hearing protectors as instructed, attending the training arranged for them and taking part in the audiometric arrangements offered. Reporting damaged controls, unsuitable protectors or changes in work that appear to alter noise exposure is part of the same contribution.
Contractors and visitors fall within the Code's scope where high levels are involved. CoP 3.0 states that no employee, contractor or visitor is to be exposed to continuous, intermittent or impact noise at or above 100 dB(A) without appropriate hearing protection. This figure and requirement come from ADOSH-SF CoP 3.0 and apply within the Emirate of Abu Dhabi.
The Code requires the employer to assess occupational noise risk. The assessment must consider the level, type and duration of exposure, including peak sound pressure, and must identify employees who may be at particular risk.
It must also consider interactions between noise and ototoxic substances, interactions between noise and vibration, and the possibility that noise may interfere with audible warning signals. Manufacturer information, quieter equipment, work beyond normal hours, supervised rest facilities, health surveillance information and the availability of suitably attenuating hearing protectors are also relevant.
Where reliable conclusions cannot be reached from existing information, exposure monitoring is required. Monitoring must represent the employee's actual exposure pattern rather than an isolated sound level chosen without regard to the work undertaken.
Where high mobility, significant variation in sound level or a significant impulse component makes area monitoring inappropriate, representative personal sampling must be used unless area sampling can be shown to provide equivalent results. This monitoring requirement comes from CoP 3.0 and applies within the Emirate of Abu Dhabi.
Monitoring must be repeated whenever a change in production, process, equipment or controls may raise exposure so that more employees reach the action level or the protectors being used become inadequate.
Employees must be informed of monitoring results where exposure reaches the action level. The information should explain the significance of the result and the controls that follow rather than presenting a decibel value without context.
At or above an eight-hour time-weighted average of 85 dB(A), CoP 3.0 requires a hearing conservation programme within the Emirate of Abu Dhabi. The programme brings together assessment, control, monitoring, protection, audiometry, information, training and record management.
The programme should be based on the findings of the noise risk assessment. Its purpose is not limited to distributing earplugs. It should identify where noise arises, who is exposed, what controls are already in place, what further action is required and how continuing effectiveness will be verified.
Noise reduction should begin with controls that act on the source or transmission path. Suitable measures may include selecting quieter equipment, modifying operating methods, enclosing noisy processes, isolating sources, maintaining machinery and limiting unnecessary access to high-noise areas.
Administrative arrangements may supplement engineering controls where exposure cannot be adequately managed by source and path controls alone. Hearing protection then provides an additional protective layer and should not be used as a reason to disregard feasible noise reduction measures.
The separate page on the hearing conservation programme explains programme administration in detail. CoP 3.0 provides the mandatory trigger and core elements for employers within the Emirate of Abu Dhabi.
Where exposure is at or above an eight-hour time-weighted average of 85 dB(A), audiometric testing must be made available at no cost under CoP 3.0 within the Emirate of Abu Dhabi.
A baseline audiogram is required within 6 months of first exposure and must be preceded by at least 14 hours without workplace noise exposure. An annual audiogram must take place within 12 months of the baseline. These timings come from CoP 3.0 and apply within the Emirate of Abu Dhabi.
Pure-tone air-conduction testing must cover each ear at a minimum of 500, 1000, 2000, 3000, 4000 and 6000 Hz. Audiometers must conform to ANSI S3.6-2010 or ISO 8253-1:2010. These technical requirements are specified by CoP 3.0 for Abu Dhabi workplaces.
The Code defines a standard threshold shift as an average change of 10 dB or more at 2000, 3000 and 4000 Hz in either ear relative to the baseline, with no allowance for presbycusis. The employee must receive written notification within 21 days in a language they understand, and a retest may be undertaken within 30 days. These figures and procedures come from CoP 3.0 and apply within the Emirate of Abu Dhabi.
Audiometric testing is part of an occupational hearing conservation process rather than an individual diagnosis. A worker who reports hearing symptoms, tinnitus, pain or other concerns should be referred to occupational health or a licensed audiologist for appropriate assessment.
At or above the action level, the employer must make suitable hearing protectors available at no cost and require their use. Selection should consider the measured exposure, the work activity, communication needs, compatibility with other protective equipment, comfort and the ability to achieve a reliable fit.
The protectors must reduce exposure to at or below an eight-hour time-weighted average of 85 dB(A). Where one protector cannot provide sufficient attenuation, double protection is required. These requirements come from ADOSH-SF CoP 3.0 and apply within the Emirate of Abu Dhabi.
For a single protector, the Code calculates attenuation using the manufacturer's noise reduction rating minus 7 dB. For double protection, plugs are assessed at their noise reduction rating minus 7 dB, while earmuffs are assessed at their noise reduction rating minus 25 per cent, rounded down to a whole number, after which the two adjusted values are summed. This calculation method is specified in CoP 3.0 for Abu Dhabi workplaces.
Warning signage must identify high-noise areas. Access arrangements should ensure that employees, contractors and visitors understand the requirement to use hearing protection before entry.
Signs do not replace assessment or physical control. They communicate an established requirement and support the management of access to an area where the employer has already evaluated the exposure.
Detailed protector selection and fit considerations are addressed on the separate hearing-protection page rather than repeated throughout the Code summary.
CoP 3.0 specifies the types of instruments to be used for exposure monitoring within the Emirate of Abu Dhabi. Measurements may be undertaken using a sound level meter conforming to ANSI S1.4-1983 (R2006) Type S2A or a personal noise dosimeter conforming to ANSI S1.25-1991 (R2007).
The instrument must use the A-weighting network and slow response and must integrate continuous, intermittent and impulsive sound levels from 80 dB(A) to 130 dB(A). These specifications come from CoP 3.0 and apply within the Emirate of Abu Dhabi.
A field calibrator conforming to EN/IEC 60942 (2003) Class LS and Class 1 and/or ANSI S1.40-1984 must be used before and after measurements. Laboratory calibration must be completed by the manufacturer or a manufacturer-approved third party.
Pre-measurement and post-measurement checks establish whether the measurement system remained stable during the monitoring period. Laboratory calibration provides traceable confirmation that the instrument continues to perform within the applicable technical requirements.
The choice between area measurement and personal sampling must follow the exposure pattern. Personal sampling is required where mobility, variation or impulse characteristics make an area reading unrepresentative unless equivalent area results can be demonstrated.
Detailed instrument selection and field methodology are addressed on the separate sound-level-meter and dosimetry pages.
Training must explain the effects of workplace noise, the purpose of monitoring, the meaning of the action level, the controls in use, the correct use and care of hearing protectors, and the purpose of audiometric testing.
At or above an eight-hour time-weighted average of 85 dB(A), training is required within 30 days of starting work and before entering a high-noise area. Employees must also be notified of monitoring results. These requirements come from CoP 3.0 and apply within the Emirate of Abu Dhabi.
Training should be provided in a form and language the employee can understand. It should reflect the actual tasks, equipment and controls encountered rather than relying solely on generic noise-awareness material.
Exposure-monitoring records and medical-surveillance records must be retained for the period of employment plus 30 years. Compliance and training records must be retained for five years. These retention periods are specified by CoP 3.0 for employers within the Emirate of Abu Dhabi.
Records should allow the employer to demonstrate what was assessed, who was exposed, what measurements were obtained, what controls were selected, what training was given and how audiometric follow-up was managed.
Compliance within the Emirate of Abu Dhabi requires the employer to implement the relevant provisions of ADOSH-SF CoP 3.0 Occupational Noise, Version 4.0, dated 15 July 2024. The Code forms part of the mandatory ADOSH-SF layer overseen by ADPHC and applies to all employers in the emirate. It is not a federal UAE instrument, and no equivalent published requirement has been identified for the other emirates or at federal level.
No. ADPHC describes Codes of Practice as mandatory for all entities regardless of risk classification. CoP 3.0 applies to all employers within the Emirate of Abu Dhabi where occupational noise is relevant.
Relying on protectors alone is poor practice. Quieter equipment, engineering control, maintenance, isolation and suitable administrative measures should all be considered, and the Code requires the risk assessment to take account of the availability of quieter equipment.
The Code's protection requirement at or above 100 dB(A) expressly names contractors and visitors alongside employees, so people entering under those conditions are within its scope. Beyond that provision, including contractors in information, access and hearing-protection arrangements is ordinary good practice.
No. It is a specific occupational hearing test forming part of the hearing conservation programme. Symptoms or clinical concerns should be referred to occupational health or a licensed audiologist.
Only where they remain representative. Monitoring must be repeated when changes in production, process, equipment or controls may bring more employees to the action level or make existing protectors inadequate.
No. It may be adopted as recognised practice or an internal organisational standard elsewhere, but its mandatory territorial application is within the Emirate of Abu Dhabi.
