A spill kit should be used to clean up a spill of a drug that is:

An expired drug, while no longer effective, does not inherently pose a risk of toxicity or harm during cleanup. Standard waste disposal procedures may apply, but a specialized spill kit is not necessary for handling expired medications, as they do not require the same level of caution as cytotoxic substances.

Controlled substances are regulated due to their potential for misuse or abuse, but not all controlled drugs are hazardous or cytotoxic. The use of a spill kit is not mandated solely based on a drug’s controlled status unless it is also classified as cytotoxic or hazardous.

Hydrophilic drugs are those that have an affinity for water and can dissolve easily in it. Their chemical nature does not determine the level of risk to health or safety during a spill. Therefore, a hydrophilic drug does not necessitate the use of a spill kit unless it is also cytotoxic or poses other specific hazards.
