Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the regulations are when the Wet Bulb globe temperature thermometer reading exceeds the upper temperature limit for training during a training event; and if he will make a statement.

Joint Service Publication 539 (Heat illness and cold injury: prevention and management) contains advice about the upper limit for activities. This recommends that a dynamic risk assessment be undertaken throughout the activity to determine whether the activity should be continued, paused or stopped.
