True or False: Petroleum base lubes should be used on the female swivel of the humat.

Using petroleum-based lubricants on the female swivel of a Humat is not advisable due to the potential degradation of materials such as rubber and plastic, which are often present in the construction of the swivels. These materials can break down when exposed to petroleum products, leading to leaks or failure of the swivel during operations. Therefore, it's essential to use lubricants that are specifically designed for the materials involved in the equipment to ensure longevity and reliable performance. This practice helps maintain the integrity of the equipment and promotes safety during firefighting activities.
