You can decide if a paint booth filter is hazardous waste by answering which of the following questions: a) is the paint an appealing color? b) is the paint residue liquid or solidified? c) does the paint being used contain any aluminum? d) are there solvents mixed in (or is it water based)?

The answer is C: Does the paint being used contain any aluminum?

Paint booth filters will be considered hazardous waste if hazardous compounds are present. The easiest way to determine if a paint booth filter is hazardous is to review the data sheets for the paint and the solvents you use. If the paint or solvents contains heavy metals like lead, aluminum, cadmium, or chromium, the spent filters would be considered a hazardous waste.

D) Are there solvents mixed in (or is it water based)?

Explanation:

Paints that have solvents in their composition are dangerous because they have a certain degree of toxicity. For this reason, these paints must be used with care and responsibility. Whoever handles this type of ink needs to protect their skin and respiratory tract from contact with these paints, because they can cause serious damage to the health of the manipulator. On the other hand, water-based paints do not present any danger to the manipulators.

For this reason, we can state that, you can decide whether a paint booth filter is a hazardous waste by answering the question "Are there solvents mixed in (or is it water based)?"
