Any personnel injuries or witnesses?
How much material is spilled, how many gallons, how many square feet on the deck?
e. DCC needs as much information as possible to decide who to send to the scene.
For example, a 5 gallon can of paint thinner was dropped down a ladder near a
storeroom. The can burst open when it hit the deck. The vestibule has no
ventilation and the flammable vapors are building. In response to this spill, the
DCA may want to send the entire fire party with charged fire hoses to the scene.
The DCA needs specific information to make proper decisions.
2. INITIATION OF ACTION
a. The most important initial actions are to evacuate personnel, secure power to the
affected area (if material is flammable), and call away a medical emergency for
any injured personnel.
b. Block off the area until help arrives.
c. The DCA, CDO, fire marshal, repair locker leader, scene leader, or other authority
will stabilize the situation before thinking about the cleanup. Stabilization may
include securing deck drains, securing ventilation, setting spill boundaries, and
staging backup personnel.
d. Once the situation is stable, injured personnel have been removed and cared for, and
there is no immediate threat of fire or explosion, then the authorities can consider
their next step.
a. The medical department representative and the HM coordinator must have an MSDS
for every hazardous material held on board. Each CDO, DCA, fire marshal, and key
player must know where to find these MSDSs and how to use them.
b. These MSDSs provide specific spill and hazard information for the spilled item. The
MSDS will tell if the item is corrosive, gives off toxic fumes, or reacts with nearby sub-
stances. In trying to decide how to handle and cleanup the spill, the MSDS informa-
tion is critical.
c. Part of an evaluation may take place during the initiation of the action phase. The
remainder may take place during the next phase of containment and damage
4. CONTAINMENT AND DAMAGE CONTROL
a. During this phase, the CDO, DCA, fire marshal, or scene leader decides if a Red Devil
blower is needed for ventilation, and if any further damage control actions, beyond the
initial action, is needed.
b. The decisions are made, based on the MSDS, what type of protective equipment is
needed, and who will dress-out to approach the spill.
c. Barriers of sand, absorbent, blankets, or paper toweling maybe placed around the spill
to prevent spreading.
d. The gas free engineering petty officer maybe required to determine explosive levels
and levels of toxic gas.
