Discussion/Options - Select optimum
course. Station additional safety observers. -
Use engineering operating sequencing system
(EOSS). And drip pans. - Phone and distance
line. Restricted maneuvering doctrine. - Use
life jackets. Station after lookout. - Use drip
pans. At sea fire party and oil lab in
standby. - Review emergency breakaway
procedures. - Review emergency breakaway
procedures. Use EOSS. - Review emergency
breakaway procedures.

4. Implement controls
- SORM. - UNREP Instruction (NWP 4 -01.4). -
OPNAVINST 5100.19C - Hold safety brief. -
UNREP checklists for all applicable
departments. - Personal protective equipment
(PPE).

5. Supervise

• Enforce controls.
• Monitor effectiveness of controls.
• Evaluate and adjust controls as the situation
• changes.
• Ensure personnel are familiar with their
• situations.
• CHANGE is the mother of all risk.
• If there is a change, a time critical process may
  have to be done on the spot.
