Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what guidance his Department issues to military personnel conducting endurance (a) exercises and (b) training in the UK when (i) 1-hour concentrations of tropospheric ozone exceeds 180 micrograms per cubic metre, (ii) the Met Office is forecasting ambient air quality to be moderate, high or very high and (iii) the Automatic Urban and Rural Monitoring Network reports moderate, high or very high air pollution.

All Defence activities are conducted under a Safety System of Work, which ensures that all reasonably foreseeable hazards, including air quality, are identified and control measures implemented.

Where risks, such as weather or air quality, change during Defence activities, a dynamic risk assessment must be carried out to ensure the risk remains manageable.
