What does 6.1-PLANT require?

Whoever designs plant for use at work must ensure, as far as is reasonably practicable, that the design carries no risk to health and safety, and tackling noise at the planning stage is both more effective and usually cheaper than fixing it once the plant is in use. Under Regulation 59 the designer must pass to everyone who receives the design, for the purpose of giving effect to it, the noise emission values of the plant (sound power or sound pressure data), the operating conditions under which those values were measured, the measurement methods, and any conditions needed for safe use. Design options worth considering: preventing or softening impacts between machine parts; quieter plastic parts in place of metal; guards combined with acoustic treatment; enclosures around the noisiest parts; power transmission that allows the quietest speed regulation, such as speed-controlled electric motors; isolation of the vibrating sources inside the machine; well-sealed machine doors; cooling flanges that avoid the need for air jets; quieter fans or mufflers in ventilation ducts; quiet motors and transmissions; pipework sized for flow speeds no higher than 5 metres per second; and inlet and other mufflers so that ducts do not carry noise from noisy rooms into quiet ones. How the plant will be maintained and serviced is taken into account in the noise control design.

6.1-BLDG Designers of buildings and structures plan noise control from the start and minimise structure-borne noise so far as is reasonably practicable, considering reverberation, layout and workstation location relative to noise sources, vibration-isolated frames, floors and machine bases, isolated plant rooms, acoustic treatment of noisy areas including absorbent ceilings and floating floors, flexible joints, walls, floors, windows and doors with the needed transmission loss, carpeted offices, and sealed, ventilated sound-insulated control rooms
6.2-INSTALL Installers ensure plant and structures are installed, constructed or commissioned without noise risk so far as is reasonably practicable, following the designer's specifications including isolating vibrating sources on separate bases or away from the building structure, and give users information on conditions for safe use including maintenance
6.2-MANUF Manufacturers ensure plant and structures are manufactured without noise risk so far as is reasonably practicable, with noise emission as low as reasonably practicable where it cannot be eliminated and no new hazards introduced, using and testing the designer's safety measures and low-noise materials and techniques, and provide importers and suppliers with the emission values, measurement conditions and methods and conditions for safe use
6.2-SUPPLY Importers and suppliers ensure plant is without noise risk at supply so far as is reasonably practicable, take all reasonable steps to obtain the manufacturer's noise emission information and pass it to everyone supplied, supply all noise controls as set up in the noise test results, and provide maintenance information for safe use
6.3 Give purchasers and users the information needed for safe use, including results of calculations, analysis and testing, the noise emission values with measurement conditions and methods, peak and where relevant continuous levels, preferably sound pressure at the operator position, the Table 5 minimum test information, and safe-use instructions in a form easily understood
6.4-CONTROL Control acoustic shock in headset work: high-quality headsets with acoustic shock protection, prompt repair of damaged equipment and network faults, proper fitting, use and maintenance of headsets, reduced background noise through room and workstation design, absorption, barriers, quiet conduct, relocated office machines and managed hot-desk changeovers, training to detect warning sounds and remove headsets, turning volume down after changeover, managing psychosocial hazards, keeping mobile phones out of call centres, and baseline audiometry at commencement
6.4-INCIDENT Manage acoustic incidents: the worker removes the headset at once, moves to a break-out area where appropriate, reports the incident and symptoms and discusses continuing work; the PCBU records and logs the event, discusses the worker's ability to continue, refers persistent or severe symptoms to a GP or audiologist, investigates the internal or external cause, checks and removes damaged or faulty equipment, and reviews the noise controls and working environment
