Jobs that require a TWIC OSHA card include positions in construction, bulk liquid handling, fire watches, and industrial cleaning. These cards represent authorization to access specific areas for your job more than the details of the job itself. In general, if your job involves traveling to a government facility to work, you may need either or both of these cards. The primary qualifications for getting these cards are passing a background check and attending any necessary classes. Fulfilling the duties and responsibilities of a job that uses a TWIC OSHA card requires attention to detail, the ability to follow safety directions, and communication skills.
