What does 5.3-AREAS require?

Areas where people may be exposed to hazardous noise should be sign-posted as hearing protector areas with clearly defined boundaries, and workers and other persons, including managers and visitors, should not enter without appropriate hearing protectors no matter how short the stay. Where sign-posting is not practicable, other arrangements should make sure workers and others know when protectors are required: prominent warning notices on tools and equipment stating that protectors must be worn when operating them, written and verbal instructions on recognising the circumstances in which protectors are needed, and effective supervision of the identified hazardous tasks.

5.1-ADMIN Use administrative controls to cut exposure time: schedule noisy work when few workers are present, give advance notice of noisy work, keep workers out of noisy areas they need not enter, provide quiet rest areas, rotate jobs before daily exposure exceeds the standard, and check regularly that administrative controls are being followed
5.1-HIER In consultation with workers and HSRs, eliminate noise risk so far as is reasonably practicable, otherwise minimise it through the hierarchy: substitute quieter plant, processes and non-ototoxic substances with a buy-quiet purchasing and hiring policy based on supplier emission data, change the way the job is done, isolate sources by distance, barriers, enclosures, absorbent surfaces and remote operation, and apply engineering controls at the source before administrative controls and PPE
5.1-MAINT Maintain plant and noise control equipment regularly, checking for changes in noise level from worn bearings and gears, poor lubrication, blunt blades, loose or unbalanced parts and air or steam leaks, and inspect and maintain vibration mounts, impact absorbers, gaskets, seals, silencers and barriers, roadways, suspensions and tyres
5.2-PLAN Implement controls through an occupational noise management plan that assigns actions, owners and dates based on the assessment and includes confirmatory measurements of attenuation achieved, purchasing and hiring specifications, training and supervision, controls for temporary work areas, and timeframes for reviewing assessments and controls
5.2-REVIEW Maintain controls so they stay fit for purpose and correctly installed and used, and review and revise them when a control fails to minimise the risk, before a change likely to create a new or different risk, when a new hazard or risk is identified, when consultation indicates it, or when an HSR requests it, using inspection, consultation, testing and records, checking the listed questions, and repeating the noise assessment on installation or removal of noise sources, changed workload or operating conditions, building changes or changed time in noisy areas
5.3-MAINT Inspect and maintain hearing protectors regularly (undamaged ear-muff seals, headband tension, no unofficial modifications, soft clean earplugs, disposable plugs worn once), train workers in use, fit, care and maintenance, write the need to wear protectors into safety procedures, put someone in charge of issue and replacements, spot-check wearing and correct use, and have managers and supervisors set the example in hearing protector areas
5.3-REG44 Where PPE is used, select it to minimise risk and ensure it suits the work and hazard, fits and is reasonably comfortable, and is maintained, repaired and replaced so it keeps working and stays clean and hygienic; provide information, training and instruction in its use, wearing, storage and maintenance; workers must use it as instructed and not misuse it
5.3-SELECT Select and maintain hearing protectors under AS/NZS 1269.3 with worker involvement and a reasonable choice of types, using supplier attenuation data (SLC80, class, octave band values measured per AS/NZS 1270), matching the class to the measured exposure per Table 4 without overprotecting, suiting the environment and task (earplugs versus ear-muffs for hygiene, heat, confined spaces and helmets), weighing comfort, weight and clamping force, and checking individual fit with the worker's usual equipment and spectacles
