An Engineman is removing a 12-volt battery from the motor whale boat. The boat is on the davit, and
the Engineman must carry the battery down the side ladder. As he lifts the battery over to the side of the
boat, his glove slips, and the battery falls about 10 feet to the deck below. The battery caps fly off and about
2 quarts of battery acid spill on the deck The acid is flowing toward the deck edge and scupper over the
side. A nearby Boatswains Mate tries to set the battery up to stop the spill and suffers acid burns on his
This spill will involve:
A medical emergency for acid bums
Stopping the spill from spreading
Using baking soda to neutralize the acid around the battery, and using personnel protective
equipment to pick it up and bag it
Spreading baking soda and scrubbing the spill area
A fire party to charge hoses and dilute the acid while washing it over the side
Personal protective equipment that would include rubber boots, rubber gloves, a rubber apron,
and goggles (a respirator may not be required)
The used hazardous material would include the broken battery and any contaminated containment
materials. The acid spill should be neutralized before washing it over the side. The alternative is to
neutralize with baking soda and absorbing it up with towels, absorbent, or other material. All this would be
bagged as used hazardous material.
An SK3 went down to the flammable liquid storeroom to break out a 5-gallon can of paint thinner
(flash point less than 100 degrees). As he carries this can up the ladder, the handle breaks off the can, and it
falls down to the bottom of the ladder. As the can hits, the cap pops off and the contents spill. The vestibule
is small and there is no ventilation in the ladder well. The SK3 tries to go down after the can, and while
trying to right the can, replace the cap, and cleanup the spill, falls unconscious in the thinner. A sailor in a
space above smells the strong vapors and phones DCC to get the fire marshal to investigate. The sailor and
the fire marshal find the unconscious SK3 and see the spilled paint thinner in the vestibule.
This spill will involve:
Explosive vapors and the need to secure sources of ignition.
A medical emergency with the SK3 overcome by the vapors and skin contact with the chemical.
A rescue would require respiratory protection but not an OBA due to flammable vapors.
Ventilating the area with a Red Devil blower.
Calling away the fire party in case of explosion and fire.
Gas-freeing the area.
Dressing out two people in goggles, organic vapor respirators, rubber boots, rubber gloves, and
Cleaning up the spill using absorbent, double plastic bagging, and marking the material as used
Decontamination of the area with soapy water.
