Basic Offshore Safety Induction and Emergency Training (BOSIET) with Compressed Air Emergency Breathing System (CA-EBS)

OPITO Standard

Product Code: 5750

Who is this Product for?

This Product is to meet the initial offshore safety and emergency response training requirements for personnel new (or returning) to the offshore oil and gas industry who will be supplied with a compressed air emergency breathing system (CA-EBS) during offshore helicopter travel.

What does this Product cover?

This Product introduces learners to the specific safety issues and regimes relevant to offshore installations and to equip them with the basic emergency response knowledge and skills for travelling to and from offshore installations by helicopter.

The objectives of the BOSIET (with CA-EBS) Training are that learners will be able to:

(a) Identify the generic hazards which are specific to offshore oil and gas installations, potential risks associated with those hazards, and how controls are put in place to eliminate or reduce risks.
(b) Identify key offshore related safety regulations and explain the basic safety management concepts.
(c) Demonstrate, in a simulated environment, that they can use the safety equipment, and follow procedures in preparing for, and during helicopter emergencies – with particular focus on escaping from a helicopter following ditching.
(d) Demonstrate sea survival and first aid techniques.

(e) Demonstrate that they can effectively use basic firefighting equipment, and practise self-rescue techniques in low visibility situations, including smoke-filled areas.

f) On the date on which the learner is to undertake shallow water CA-EBS training, and prior to entering the water in which the training takes place, the learner gives to the OPITO-approved Centre a statement, that to the best of the learner’s knowledge and belief, the learner has no (current or past) medical condition which makes the learner unfit to participate in the training.

Learners must not participate in Additional CA-EBS Training (In-Water) practical exercises if they are unable to meet the requirements of d), e) and f) above.

Note 2: Please note that learners who possess a valid and current certificate of medical fitness provided by an Approved Medical Examiner of Diving (AMED) will not be required to undertake d) and e) above as they have already met the requirements of the Diving at Work Regulations 1997.
