A Member has forwarded its recently-issued safety reminder concerning the use of prescription medicines.
Sometimes, employees who are under treatment of a qualified doctor may be prescribed to take medicine(s) that may impair work performance or weaken reflexes, especially in the event of an emergency.
- While under medical treatment, it is the responsibility of all such employees to make the vessel master or diving supervisor aware of such a situation/condition.
- It is also the responsibility of the master/supervisor to enquire of new/transferred employees during familiarisation whether they are under medical treatment/taking prescription drugs. The purpose of identifying such personnel is for the master/supervisor to be aware of their limitations in work performance and in the event of any emergency, thus preventing a potential accident.
