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.
