 As the typical wiper is aboard a vessel and underway, although they may be found in land-based operations such as railroading as well, they must be fluent in ship operations and have familiarity with safety equipment used.As the United States Merchant Marine is strict in compliance of international organization's precedent in regards to regulations on shipping, having to adhere to the standards set by the International Maritime Organization (IMO), many of the same requirements can be found for vessels that do not serve under the United States Jones Act.In relation to this requirement, a wiper is to be sufficiently trained on how to carry out firefighting operations; this includes the proper donning, assembly, use, and maintenance of all equipment involved should the need arise in order to facilitate the need for all seafarers to be fluent in lifesaving procedures These requirements are mandatory and are also adhered to on an international and involuntary basis with the need to renew the very same preliminary physical and firefighting examinations found within CFR 46.
