AONA Environmental has completed Occupational Air Quality monitoring and Noise at Work surveys for a large number of workplaces ranging from pharmaceutical facilities to power plants. Our clients include Abbvie Ltd., Baxter Healthcare, Tynagh Energy Ltd., Balcas Timber Ltd., Barna Waste, Americk Packaging among others.
AONA Environmental have undertaken Occupational Air Quality monitoring for a range of gaseous chemicals and dusts using both personal and static sampling methods. Frequently requested analysis includes inhalable and respirable dust, respirable silica, rubber fumes, volatile organic compounds, polycyclic aromatic hydrocarbons (PAH), aldehydes, etc.
Sample analysis is undertaken by a UKAS accredited laboratory. As part of our Occupational Air Quality monitoring, reporting and auditing we determine daily exposure and time weighted averaged concentrations which are compared against the relevant Workplace Exposure Limits (WELs). Where an exceedance of occupational air quality limit values are reported, we provide cost-effective advice and solutions to resolve such issues.
Noise at Work
Noise at work surveys measure the level of noise to which employees are exposed to in their day to day working environment. Where the continuous or regular use of machinery or power tools produce a background noise level resulting in employees having some level of difficulty holding a conversation, usually a noise survey is conducted to identify the source and determine its relative contribution to the area noise level and the employees noise exposure. A noise survey is conducted at suitable locations and time durations to ensure that monitoring is representative of the employees daily personal exposure. The standard instrument used for measuring noise is a sound level meter. In addition, AONA Environmental can provide dose badge personal noise dosimeters as a way of determining the daily personal exposure of an employee in high noise / high risk areas.
Noise at work legislation provides legal limits on noise exposure in the workplace. These limits are based on a worker’s time weighted average over an 8-hour day. The level at which employers must provide hearing protection and hearing protection zones is 85 decibels (daily or weekly average exposure) and the level at which employers must assess the risk to workers health and provide them with information and training is 80 decibels.
By carrying out noise at work surveys and ensuring that recommended guidelines are adhered to, noise-induced hearing loss in the workplace is entirely preventable.
