Ms Maev Nic Lochlainn:

There are specific drug and alcohol provisions in the Bill relating to railway safety. On the aviation side, I understand random testing is conducted. Many such tasks in the transport sector are safety-critical. As I understand it, in aviation, the codes were developed under the Safety, Health and Welfare at Work Acts where one is obliged to have safe employees and safe practices to protect one's own safety and the safety of passengers. Health and safety legislation is used, as far as I understand it.
