Its primary responsibility is to oversee the safety of workers and employees in the country through standards and regulations they have set, which employers and business owners must strictly follow. Violation could lead to fines or penalties; a lawsuit, or in worst-case scenarios, temporary business closure or revocation of license to operate (whichever is applicable).

In general, the OSHA regulates employees’ working conditions, making sure that they are provided with a safe, healthy, and comfortable working environment at all times. And part of the working environment are pieces of equipment used in day-to-day operations. For ships, these include ladders.

In general, OSHA-rated ship ladders have fulfilled the following requirements:
