Conference Programme

08.30 Registration

09.00 Conference Opening Dr Eoin Collins OHSI Hon. Pres.

09.10 Annual Tom O' Connor Lecture: The Ebola Disease Outbreak in Africa - Experiences from the Laboratory
Dr. Brian Crook, HSL

Following on from the Health & Safety Laboratory's and Health & Safety Executive's involvement in the outbreak management in Sierra Leone, HSL microbiologist Brian Crook volunteered and took up 5 week deployments in March-April, and again in July-August 2015, to work in a laboratory at the Ebola Treatment Centre run by International Medical Corps near Makeni, in northern Sierra Leone. This presentation will describe the background to his deployment, the work undertaken including the challenges of applying safety procedures in limited facilities, but also the rewards of working with a humanitarian aid organisation.

09.50 Legionella Risk Assessment and Control Strategies
Dr Bill Thomas, ISHEM Consulting

Bill will explore risk assessment and control strategies to meet current regulatory requirements. He will discuss the expectations of the regulator and how best to fulfil them by reference to some recent case studies where duty holders have managed to avoid prosecution by adopting a proactive risk management approach. Cooling tower cleanliness assessments will also be discussed, together with current views on risks from adiabatic cooling equipment.

10.30 Update on Biological Agents 2013
Nicholas de Paor, HSA

The presentation will review the 2013 Biological Agents Regulations, their associated Code of Practice and the guidelines issued by the HSA on the Regulations and Code of Practice; the reasons for updating the Regulations; a review of biological notification to the authority; the biological issues encountered by inspectors during inspections.


11.40 Update on REACH and CLP Regulations
Caroline Walsh, HSA

This presentation includes the 2018 registration deadline; the latest application dates for authorisation for SVHC's, the new SDS format, what to expect from an exposure scenario, ECHA supports for downstream users, overview of the latest ATPs to REACH and CLP and what guidance, support and help is available.

14.30 Occupational Health in the HSA Strategy 2016 - 2018
Martin O'Halloran, HSA

We are delighted to welcome the Chief Executive of the Health and Safety Authority to present at our 2016 Conference.

15.10 Indoor Air Quality in Energy Efficient Homes
Aine Broderick, NUIG

The objective of this study is to evaluate the impact of an energy efficient retrofit on indoor air pollutant levels and comfort in homes across two seasons. A variety of research questions will be addressed, including exploring the effects of factors such as building occupancy patterns and retrofit status on indoor pollution concentrations. Thermal comfort and occupant behaviour in these homes will also be assessed using an occupant survey.

15.30 HVAC Systems and Indoor Air Quality
Martin Deevy, Enviro Hygiene

This presentation explores how ventilation systems become contaminated and the dangers of contaminated ventilation systems. The relationship between a building and a ventilation system, sensitivity of air quality investigations with building occupants and trade unions and case studies will also be presented.
