The Defence Secretary has told ITV News lessons have been learnt when it comes to military training exercises.
It follows the Health and Safety Executive's criticism of the way risks were assessed during an SAS selection exercise in the Brecon Beacons in July, which left three reservists dead.
Today Philip Hammond said reservists can be confident that changes have been made.
The notice served by the Health and Safety Executive says the Ministry of Defence:
- Failed to make a suitable and sufficient assessment of the risks to the health and safety of employees, namely those soldiers participating in the aptitude phase in the Brecon Beacons on July 13
- Failed to properly identify the risks associated with the activity and implement effective measures to control them, including those relating to heat illness
- Failed to review the risk assessment when it became clear persons participating in the test were suffering from heat illness
The HSE notice went on: 'These contraventions are likely to continue or be repeated during the planning of, training for and carrying out of future selection tests of this nature'.
The Ministry of Defence has released a statement saying it will implement all of the HSE's recommendations.
– Ministry of Defence spokesperson
Our thoughts remain with the families of those who died on this exercise.
We have co-operated fully with the Health and Safety Executive inspectors and are implementing all the recommendations in the Crown Improvement Notice.
As the incident is still subject to a Police and MOD investigation it would be inappropriate to comment further.
