Biography information for The Countess of Mar – 2015 Parliamentary Question to the Department for Transport
The below Parliamentary question was asked by Biography information for The Countess of Mar on 2015-12-02.
To ask Her Majesty’s Government further to the Written Answer by Lord Ahmad of Wimbledon on 16 July (HL1538), whether, in preparing that answer, they took account that of the substances in jet engine oils, only tri-ortho-cresyl phosphate has an exposure standard or short-term exposure limit, and that EH40/2005 Workplace Exposure Limits states that the absence of a workplace exposure limit does not indicate that [a substance] is safe”
Lord Ahmad of Wimbledon
The previous answer took account of all the substances referred to in the Cranfield University’s Aircraft Cabin Air Sampling Study regardless of whether they are subject to Workplace Exposure Limits. For example, two of the substances measured (tolulene and carbon monoxide) are the subject of a European standard for safety, health and comfort limits (BS EN 4618:2009). In addition to this, for the substances that do not have a European standard, other limits and guidelines have been considered in assessing the significance of any health risk of exposure to the concentrations measured in cabin air. Several of the substances monitored during the research, for example TBP, TOCP and tetrachloroethylene, have workplace exposure limits (WEL). For substances that do not have a WEL, a number of guidelines were used that have been recommended by the World Health Organisation as well as different groups in the UK and EU. These groups include Kotzias et al, Department for Communities and Local Government (DCLG) and Committee on the Medical Effect of Air Pollutants (COMEAP).
