Sep 13, 2017 · Safe use of machinery. This guideline is aimed at employers, engineers, designers, manufacturers and distributors of machinery. WorkSafe has also developed a set of fact sheets for specific machinery. Though relevant to employers, these fact sheets are mostly aimed at operators and employees.
Feb 02, 2021 · Consequently – and much to the annoyance of HSE – practical and cost-effective noise control advice in noise assessors' reports is conspicuous by its absence. A little understood fact is that if you reduce noise by 3dB you have cut the risk of harmful noise exposure by 50 per cent. However, cut it by 7dB and the risk reduction is 80 per cent.
May 21, 2021 · An eight-wheel tipper truck has been crushed by the Environment Agency (EA) under new powers to combat fly tipping. The vehicle is believed to belong to an organised crime group operating in the South East and was discovered near Iwade, outside Sittingbourne in Kent, during a waste crime investigation. The truck was seen at a […]
Jul 07, 2017 · Engineering intervention case studies. We found 12 studies that described 107 uncontrolled case studies of immediate reductions in noise levels of machinery ranging from 11.1 to 19.7 dB(A) as a result of purchasing new equipment, segregating noise sources or installing panels or curtains around sources.
However, this is independent from the health-related costs of noise pollution. The level of truck noise pollution is influenced by several factors such as vehicle speeds, traffic flow (free flow vs. stop and go), road surfaces, weather, and vehicle type and conditions. The index used for noise is the energy mean sound level, [dB(A) 6]. It gives
HSE Noise: Sound Solutions Case Studies. Reducing noise in gravel chutes case study 1 A major noise source in quarrying and mineral workings is from materials dropping onto steel chutes or into hoppers. A lower noise alternative for compressed air drying case study 2 Compressed air jets, widely used in industry for drying, can emit excessive
Construction Dust Causes, Effects and Remedies. Construction dust can seriously damage the health of construction workers and if exposed for longer times can eventually even kill them. About 22,000 to 52,000 persons per year are dying due to inhaling polluted air in USA alone – most of whom are construction workers.
In some cases noise levels can be reduced by lining hoppers, chutes and conveyors, but in others the ambient conditions do not allow such techniques. Alternative approaches then have to be considered. One such example was a machine used in processing cocoa beans. The beans were transported along a vibrating tray beneath an array of gas burners.
The safest alarms in the world due to their instant location and directional sound. The multi-frequency alarms are only heard in the danger zone, thus eliminating noise nuisance for local residents. Medium duty alarms are ideal for commercial road going vehicles and environments with mid-level ambient noise.
Noise. Noise means unwanted sound or loud discordant or disagreeable sound or sounds. The effect of noise on hearing can be temporary or permanent. Temporary deafness is often experienced after leaving a noisy place. Although hearing recovers within a few hours, this should not be ignored as it is a sign that continued or regular exposure to
A three-fold approach to noise reduction was taken: the large surface areas of the cab, roof, bulkhead and door panels were treated by the application of 10 mm thick bitumastic damping pads to reduce resonant vibration; a proprietary sound barrier mat consisting of a lead/fibreglass laminate was applied to the floor and engine bulkhead; an
Nov 09, 2016 · Noise and vibration have significant health implications; they both arise from the same mechanism. Excessive noise exposure gradually damages hearing, making communication more difficult, whilst poor control of hand-transmitted vibration can give rise to disabling loss of manual dexterity, which reduces workers' productivity.
manufacturers to reduce the noise footprint of their products. The new specification uses a formula to determine the allowable sound pressure level based on the power of the machine. In this case, the new standard required a noise reduction of about 6 dB(A) relative to the existing design. The noise measurements are based on the ISO 6393
The solution. One company carrying out large-scale quarrying operations reduced noise levels by lining the bodies of its 20-tonne dump trucks with abrasion-resistant rubber. Sheets 50 mm thick were used, and moulded so that a profiled section of 200 mm overall depth was obtained. The sheets were then attached mechanically to the body of the truck.
HSE - Noise: Sound Solutions Case Studies
Occupational audiometry is a screening technique used to detect early damage to hearing resulting from exposure to noise. The Control of Noise at Work Regulations 2005 requires employers to prevent or reduce risks to health & safety from exposure to noise at work. Employers have duties under the Regulations to: Assess the risks from noise at work.
HSE (listed in telephone directories) or the HSE Infoline 08701 545500. 1.11 In this Code sections 1 to 6 outline the general requirements and basic principles of load safety, and sections 7 to 18 provide advice. This advice is based on proven good practice, on the satisfactory methods for securing the more common types of load.
case studies A major US Frac service provider engaged MGB Oilfield Solutions to assist them in reducing fracturing cost while maintaining operational efficiency. The Marcellus site provided a perfect opportunity to do a comparison between previous well-site operations and using the MGB PowerCell system.
Reducing noise in gravel chutes (case study #1) A major noise source in quarrying and mineral workings is from materials dropping onto steel chutes or into hoppers. A lower noise alternative for compressed air drying (case study #2) Compressed air jets, widely used in industry for drying, can emit excessive levels of noise from the high jet
