What is the minimum manning level for high pressure water blasting operations at 120 fsw?

In high pressure water blasting operations at depths such as 120 feet of seawater (fsw), the minimum manning level is established to ensure both safety and operational effectiveness. Having a minimum of four personnel on-site allows for adequate coverage of various critical roles, which is essential given the potential hazards associated with high-pressure equipment and underwater operations.

The presence of multiple team members enhances the safety protocols, ensuring that in the event of an emergency, there are enough trained personnel available to respond effectively. This includes having a dedicated operator for the water blasting equipment, a safety diver observing and assisting, as well as support personnel for communication and surface monitoring. Additionally, this level of manning facilitates proper buddy diving practices and allows for rest periods, which are crucial for maintaining focus and performance in a challenging underwater environment.

This structured approach to manning during high-risk operations like water blasting complies with industry safety regulations and best practices, fostering a culture of safety and minimizing risks associated with underwater work.
