Question: How should spill cleaning materials be discarded?

Select one:

a. Leave them in the fume hood for the instructor.

b. Rinse the cleaning materials in the sink, then place them in the trash can.

c. Discard all components in the broken glats container.

d. Seal in a labeled plastic bag, then place in the solid waste container.

Expert Verified Solution:

The correct answer is:

d. Seal in a labeled plastic bag, then place in the solid waste container.

Explanation:

Spill cleaning materials, such as absorbent pads or paper towels used to clean up chemical spills, may contain hazardous residues. It is important to handle and dispose of them properly to prevent any contamination or exposure to hazardous substances.

Option D is the correct procedure because it involves:

Sealing the contaminated materials in a labeled plastic bag to contain any hazardous substances.

Placing the sealed bag in a solid waste container that is designated for hazardous or contaminated waste.

Other options are incorrect because:

a. Leave them in the fume hood for the instructor: This is not a safe or proper disposal method and could lead to exposure or accidents.

b. Rinse the cleaning materials in the sink, then place them in the trash can: This is unsafe as it could contaminate the sink and the general waste stream.

c. Discard all components in the broken glass container: This is inappropriate as the broken glass container is specifically for sharps and broken glassware, not for chemical-contaminated materials.

Therefore, option D ensures proper containment and disposal, minimizing any risk of exposure or environmental contamination.
