The scope of this training is to familiarize me with the following: *

1 puan

Resource Conservation and Recovery Act hazardous waste regulations

UAF hazardous waste procedures

Emergency procedures

all of the above.

The hazardous waste regulations (RCRA) require that hazardous wastes be identified:

1 puan

By trained personnel at the licensed Treatment and Disposal Facility

By the EHSRM Hazmat personnel

By the person generating the waste, at the point of generation

Never—there is no need to identify the hazardous characteristics of a waste generated at a University.

Containers of chemicals do not need to be labeled if you are the only person in the lab who is using the chemical.

1 puan

True

False

A lab tech uses ethanol in a procedure where the final concentration is 30%. They should:

1 puan

Collect the waste in an appropriate container and label with the words “30% ethanol waste, flammable”, and with the date that collection began

Collect the waste in an appropriate waste container and label as “waste” and include the date that collection began

Pour the waste down the drain—it is not regulated.

Collect the waste in an appropriate container and wait until it is full before requesting a hazardous waste pickup. EHSRM staff will label the container when they pick it up.

Pipet tips that have been used to dispense mercuric chloride solutions should be:

1 puan

Disposed of in the regular trash.

Left to dry in the fume hood and then disposed of in the regular trash.

Placed into an appropriate waste container labeled “Mercuric chloride-contaminated solid waste, toxic” and the date when the collection starts.

Placed into a red sharps container marked “Biohazard”.

A grad student accidentally drops a 4 L bottle of acetonitrile on the floor, breaking it. No one is injured in the accident and their lab coat keeps it from getting on their clothing and skin. Acetonitrile is a flammable solvent that can be metabolized into cyanide when it enters the body via inhalation or skin contact. They should:

1 puan

Wipe it up with paper towels and collect the towels for disposal.

Wipe it up with universal spill pads and collect the pads for disposal.

Evacuate the lab and call EHSRM for assistance.

Get another bottle out of the flammable cabinet and let the spill evaporate while proceeding with his experiment.

In the event of a fire or emergency in my building, I should

1 puan

Leave the building, using the nearest elevator.

Activate the fire alarm if needed, leave the building by the nearest safe exit, and meet at the evacuation assembly point for the building.

Close my door and continue working.

Leave the building, take the rest of the day off, and tell my supervisor about it the next day.

Bob uses disposable pipet tips to dispense chloroform into his sample tubes. Bob should:
*

1 puan

Put the tips in a beaker or other container and let them air dry briefly in the fume hood before discarding into the regular lab trash.

Put the tips in a beaker or other container and let them air dry briefly in the fume hood before putting them in a waste container labeled “Chloroform-contaminated pipet tips, toxic” and the date that he started collecting them.

Put the tips in a waste container labeled “Chloroform-contaminated pipet tips, toxic”, and the date that he started putting collecting them.

Let the tips air dry and reuse them

A researcher collects acetone waste in 4 L glass jugs, which can take 4-6 weeks to fill completely. Acetone is a U-listed chemical. During this time (when wastes are not being actively added to the jug) the wastes should be stored:

1 puan

In the fume hood

With the lids off to assist in evaporation of the waste so that they can get more into the jug

In the flammable cabinet in the lab

Nowhere—they are not allowed to collect this much acetone waste at one time and should request that it be picked up daily
