Occupational Hygiene – Air Monitoring.
The Health and Safety Authority of Ireland have published Occupational Exposure Limit values for hundreds of chemicals in their Code of Practice for the Chemical Agents and Carcinogen regulations. Employers must ensure that workers are not exposed to concentrations above these limits. Occupational hygiene air monitoring can give vital information regarding workers exposure to gases, vapors, dusts, fibers, and fumes in the
workplace for compliance testing against these limit values. Monitoring can also be carried out for other reasons such as to assess controls, containment testing of equipment, identify sources of contamination or baseline checks. Wright Environmental Services routinely carry out these assessments for clients after which a report is issued where results are assessed and observation/recommendations made using our extensive experience.
When conducting occupational hygiene air monitoring, a worker is usually fitted with a sampling pump (personal exposure monitoring) connected to a sample collection device and monitored over a period of time. The sample is then analysed for the contaminant in question. This is followed by a series of calculations to determine the workers occupational exposure to
that contaminant.
Occupational Hygiene – Containment Testing
The containment capability of equipment is an important factor in evaluating the risks associated with the handling of pharmaceutical ingredients. Wright Environmental Services routinely conduct containment performance testing on equipment (including personal sampling) to demonstrate that the Containment Performance Target to which the equipment was designed has been met. These assessments are based on ISPE Good Practice Guide:
Assessing the Particulate Containment Performance of Pharmaceutical Equipment. The Guide provides a set of principles and standardized methodologies for evaluating the containment capability of pharmaceutical equipment. The methodologies involve the sampling and analysis for airborne emissions and surface contamination of a surrogate material manipulated within the equipment.
Indoor Air Quality Surveys
Complaints of stuffy atmosphere, headaches, sinus irritation or dry air are commonplace in many workplaces. This is often referred to as “Sick Building Syndrome”. Wright Environmental Services have the experience and knowledge to carry out a thorough and comprehensive indoor air quality investigation to determine the quality of the indoor air in the workplace and provide guidance on recommended standards.
Odour Investigation
Nuisance odours can cause problems and complaints in offices and factories. With our knowledge and experience, we can carry out odour investigations to help our clients identify and eliminate the problems and complaints.
Ambient Air Monitoring (Dust fall out)
Ambient air monitoring is an important part of a company’s environmental management system. Monitoring may be carried out for various reasons; EPA requirement, local authority requirement, complaints, determination of background levels, Environmental Impact Assessments etc.
Wright Environmental Services have many years experience providing such a professional service to clients. We install, change, collect and analysis deposit gauges to measure dust fall out concentrations using Bergerhoff gauges. We then provide a comprehensive report to our
client, comparing results to relevant standards.
