REVIEW QUESTION: 

REVIEW QUESTION WHAT RULES APPLY WITH RESPECT TO THE DISCHARGE OF AFFF INTO THE SEA WHEN: INPORT / 3NM FROM LAND? PROHIBITED 3 -12 NM FROM LAND? IF SHIP SPEED IS > 10 KTS >12 NM FROM LAND? DISCHARGE AT WILL

REVIEW QUESTION: 

REVIEW QUESTION DESCRIBE THE ACTIVATION SEQUENCE IN A 2 SPEED INJECTION SYSTEM WHEN THE LOW FLOW RATE DEMAND CIRCUIT IS ENERGIZED. THE MASTER SOPV IS ENERGIZED, STARTING THE AFFF CONCENTRATE PUMP ON SLOW AND OPENING THE HYCHECK AND POWERCHECK VALVES AS WELL AS ENERGIZING THE SOPV FOR THE LOW FLOW RATE GROUP (MINUS HOSE REELS)
