5. DISPERSION OF GASES AND VAPORSa. Ventilation from the surrounding area, a Red Devil blower, ram fan air mover, or localexhaust system may be used to reduce explosive levels, or to disperse or dilute air con-taminants.b. Take care when exhausting vapors and gases to the weather decks to prevent re-intro-ducing them into the ship.c. The gas free engineering petty officer uses meters and Draeger tubes to check forventilation.6. CLEANUP AND DECONTAMINATIONa. Once the initial phases are complete, the team can take its time cleaning up the spilland decontaminating the area. Remember that cleanup personnel must beappointed and supervised as they don the required protective clothing. Protectiveclothing is provided in each ship’s spill cleanup kit, kept in or near a repair locker.Notetotheinstructor:If your ship has the spill cleanup kit available, breakout the kit and show all thecomponents to the students. Explain the use of each item.b. During cleanup and decontamination, one person supervises the cleanup while theothers assist. The DCA, CDO, fire marshal, or scene leader will decide what protec-tive clothing and respiratory protection is required and instruct the team membersin the cleanup.7. DISPOSAL OF CONTAMINATED MATERIALSa. All the spilled material, absorbent, disposable clothing contaminated with the spilledmaterial, and items which cannot be decontaminated are considered used hazardousmaterial. These items must be double-bagged in plastic or placed in an empty drumor barrel and sealed. The material must be labeled with a hazardous chemical label.The material must then be turned over to the supply department for disposal.b. You must decontaminate reusable items, such as rubber boots, dustpans, brooms,and mops before reuse. Place them in a doubled, plastic, labeled bag until you canaccomplish the decontamination. The safety officer or the HM coordinator will helpdecide how to safely decontaminate reusable spill equipment.8. CERTIFICATION FOR SAFE REENTRYOnce the decontamination is completed, the CDO, DCA, or fire marshal inspects the areato be sure the cleanup is complete. If toxic gases or vapors were involved the area alsomay need to be cleared by the gas free engineer.9. FOLLOW-UP REPORTSa. The spill response should be logged in the DCC log (Engineering Log) and the ship’sdeck log.b. The CDO may want a written report to present to the CO or XO. Give a copy of thismemo to the HM coordinator.c. If there was local press interest, or if the spill caused fatalities or excessive damage, anOPREP-3 is probably required. Spills, such as oil, mercury, and PCBs have their ownreporting requirements.Figure 1-1.—Sample lesson plan—Continued.1-7
