A carabiner is normally marked with which of the following?

A carabiner is typically marked with the Minimum Breaking Strength (MBS), which indicates the maximum load the carabiner can withstand before breaking. This marking is critical for safety, as it informs users of the limits of the equipment, ensuring they do not exceed these limits during operations.

Understanding the MBS is essential for rope access technicians, as it helps them select the appropriate gear based on the loads they will be working with. When planning for tasks, technicians must ensure that the combined weight of tools, personal gear, and any other loads do not approach or exceed the MBS of the equipment used.

Other concepts like Working Load Limit (WLL) and Safe Working Load (SWL) are also relevant in the context of working loads but may not be specifically marked on carabiners themselves. The Design Factor refers to the ratio of the MBS to the WLL, providing another safety margin but, again, is not typically the information marked on the carabiner. The emphasis on MBS ensures users have immediate and clear information regarding the equipment's breaking strength, thereby promoting safe practices.
