Which statements regarding diking at a HAZMAT spill are TRUE?

1. Use whatever on-scene resources are available such as tree limbs, boards, ladders or bagged materials 2. Covering the dike with plastic sheeting or tarps can slow seepage 3. Applying an outer layer of dirt can slow seepage

It is generally best to have at least BLANK responders work on preparing a diversion dike?

3

What angle should a diversion dike be in order to redirect a fast moving HAZMAT spill?

60 degress or more

To secure a storm drain or manhole cover from spilled product, lay a sheet of plywood or plastic over it, extending it at least BLANK around the outer edge of the manhole cover?

8 inches (20 CM)

BLANK materials soak up product and can become saturated?

Absorbent

At a HAZMAT spill, damming involves?

Constructing a barrier across a waterway to stop or control product flow

BLANK involves redirecting the flow of the spilled product to another area where less harm will result from contamination?

Diverting

A flammable liquid spill should be contained to the smallest area and as close to the source as practical so any ignition will be contained in a small area to make extinguishment easier. T or F?

False

Circle dikes should never be used in retaining operations. T or F?

False

Containment operations should be performed by choosing only one method, diking, diverting, damming or retaining; a combination of methods is not practical. T or F?

False

Most HAZMAT spill control equipment is specialized and expensive to purchase. T or F?

False Most HAZMAT spill control equipment is neither specialized nor expensive. The equipment and materials include many items you already have as well as others you could easily acquire

Because of the risk of sparking, mechanical equipment should never be used at a HAZMAT spill. T or F?

False The risk of sparking should be taken into consideration, but use mechanical equipment whenever possible. Work smarter, not harder.

When responding to a HAZMAT spill, you should make sure that the spill is properly contained or diverted and then attempt to identify the product. T or F?

False When responding to a HAZMAT spill, you should idenity the product before attempting to divert or contain the spill

At a flowing HAZMAT spill, where should you perform confinement measures?

In advance of the leading edge of the spill

At a HAZMAT spill involving a waterway, how do you trap material heavier than water but allow uncontaminated water to flow?

Overflow dam

Combustibles should be removed from the vicinity of a corrosives spill or the spill should be diverted away from combustibles to limit the?

Risk of fire

The primary objective of hazardous material spill control is to?

Stop the flow of prodcut in order to protect life, property and the environement

What is the goal of retention operations?

Temporary confinement of the prodcut to an area where it can later be absorbed or vacuumed up after dilution or neutralization

At a HAZMAT spill, what does an underflow dam do?

Traps material lighter than water behind the dam, allowing uncontaminated water to flow undeneath the dam

Applying water to a HAZMAT spill can sometimes make the situation worse. T or F?

True

Some retention methods involve creating a basin to capture flowing product. T or F?

True

The circle dike completely encloses the material and it is usually used with slow-moving materials. T or F?

True

To divert a HAZMAT spill, position a diversion dike in advance of the spill so the product will flow in a different direction. This can be accomplished by shoveling dirt into a solid barrier. T or F?

True

As a general rule, a good first option at a HAZMAT spill may be to control the leak at the source instead of only trying to contain the spill by digging retention ponds. T or F?

True Attempt to control the release at the source. For example plugging a leak
