and is used in CW defense to help accomplish themission.The MOPP doesn’t require that personnel wearprotective clothing all the time. Duty requirements,body heat buildup, and basic human needs will preventyou from using full protective equipment for an infiniteperiod of time. The MOPP does, however, give the COthe option of no protection to full protection, dependingon the threat to the ship.All operations are conducted under the MOPPsystem, even when there is no threat. There are fourlevels of MOPP—from Level-1, the least protection, toLevel-4, the most protection.MOPP Level-11. Individual protective equipment and medicalsupply items are issued to shipboard personneland maintained at respective battle stations.Protective masks are fitted for immediate use.2. Inventory stowed chemical/biological defenseequipment and supplies.3. Set readiness Condition III and materialcondition YOKE, if not already set.MOPP Level-21. For both chemical and biological threats,protective mask is in a carrier and worn on theperson.2. Preposition decontamination supplies in deconstations and at repair lockers. Prepositionstowed detection and monitoring equipment,supplies, and empty canteens as specified in theship’s CBR Defense Bill.3. Set material condition ZEBRA (modified).MOPP Level-31. Install new filter canisters on protective masks,maintain in a carrier and on the person. Providewet-weather gear for donning over otherprotective clothing and equipment for weatherdeck activities. Don overgarment trousers andcoat with hood down. Don chemical-protectiveoverboots. Stow personnel decontamination kitin mask carrier. Stow chemical-protective gloveset and medical supply items in pocket onovergarment coat. Initiate pyridostigminepretreatment regimen.2. Go to general quarters (GQ) (readinessCondition I may be relaxed and readinessCondition II set at CO’s discretion); set materialcondition ZEBRA.3. Fill prepositioned canteens with potable water.4. Activate decontamination stations andcontamination control areas (CCAs) and assureoperability. Post detection and monitoringteams.5. Post and monitor detection equipment andmaterials as designated by the ship’s CBRDefense Bill.6. Activate countermeasures washdown systemintermittently.MOPP Level-41. Don protective mask and secure hood over headand around mask. Don chemical-protectiveglove set.2. Direct ship to GQ (if not previously in effect).3. Initiate continuous monitoring and operation ofdetection equipment.4. Set CIRCLE WILLIAM.5. Activate countermeasures washdown system tooperate continuously.The setting of MOPP levels may be different atvarious locations around the ship. This depends on themission, work rate, and heat buildup in these battlestation areas (engine rooms, combat information center,flight deck, and so on).REVIEW 6 QUESTIONSQ1.
