6.2 PPE During Cleaning: Glove Change Frequency & Disposal

PPE During Cleaning: Glove Change Frequency & Disposal

Cleaning, deactivating, and decontaminating HD-contact surfaces is one of the most frequent tasks in an HD program — performed at the end of every shift, after every spill, and on a fixed daily or weekly schedule for primary engineering controls. Because cleaning feels routine, staff sometimes treat it as lower-risk than compounding. USP <800> does not make that distinction: any task that puts skin or clothing in contact with an HD-contaminated surface requires the same rigor as handling the drug itself, including the correct PPE and a disciplined glove-change schedule. The exam tests this section heavily through “how long can I keep wearing these gloves” and “what do I do with this used wipe” style scenario questions.

PPE Required for Cleaning Tasks

This is the same ASTM D6978 chemo-glove standard used during compounding — cleaning does not get a lighter-weight glove just because no drug is being prepared. If the surface was in contact with an HD, the glove standard does not change.

Glove Change Frequency

Gloves must be changed under two independent triggers, and the exam expects you to recognize both:

The wear-time trigger is the one test-takers most often miss. Permeation resistance is a function of time, not just visible integrity — an intact-looking glove can still allow HD molecules to migrate through the material once the manufacturer's tested window has elapsed. This means an extended cleaning task, such as a scheduled deep clean of a containment primary engineering control (C-PEC) that runs 45–60 minutes, requires a glove change partway through even if the gloves show no rips.

Exam Tip: Two glove-change triggers exist independently — visible damage OR elapsed wear-time. Either one alone is sufficient to require a change.

Gown Handling

Disposable gowns used during cleaning follow a simpler rule: single use. A gown is discarded after one cleaning task, or immediately if it becomes visibly contaminated or torn during the task — whichever comes first. A gown is never reused between cleaning sessions and never repurposed from a cleaning task into a compounding task (or vice versa); each task gets fresh PPE.

Disposal of Contaminated Materials

Everything that contacts an HD-contaminated surface during cleaning becomes HD waste:

• Used gloves, gowns, and any eye/face protection removed after the task
• Wipes, absorbent pads, and spent cleaning agents
• Any packaging from single-use cleaning supplies

All of it goes into HD/chemo-labeled waste containers, never general trash, recycling, or a standard biohazard bin. Mixing HD-contaminated cleaning waste into regular trash is both a regulatory violation and a direct exposure risk for downstream housekeeping and waste-handling staff who have no reason to expect hazardous contact.

Doffing Order Matters Too

Even during a routine cleaning task, PPE must come off in the order specified by the facility SOP (generally outer, more-contaminated items first) so that the person removing gear does not transfer HD residue from a glove to bare skin or clothing. A technician who is careful about glove-change timing but careless about removal order can still contaminate themselves at the very end of an otherwise correct cleaning task.

Exam Scenario

A technician is assigned the facility's daily 50-minute deep clean of the C-SCA hood. She dons double chemo gloves (ASTM D6978) and a disposable non-permeable gown at the start. At the 40-minute mark, the gloves show no visible tears, but the manufacturer's label specifies a 30-minute permeation-resistance window for the cleaning agent in use. The correct action is to stop and change gloves at that point — not to continue because the gloves “look fine.” At the end of the task, the gown, gloves, and all used wipes go into the HD waste container, and a fresh gown and gloves are used for the next task.

Key Takeaways for the Exam

• Cleaning tasks require the same ASTM D6978 chemo-glove standard as compounding — there is no reduced-rigor PPE tier for “just cleaning.”
• Gloves change on two independent triggers: immediately if torn/punctured, or at the manufacturer's specified wear-time limit (commonly 30–60 minutes), even without visible damage.
• Extended cleaning tasks (deep cleans, large spill cleanup) require a mid-task glove change once the wear-time limit is reached.
• Gowns used for cleaning are single-use: discarded after each task or immediately if contaminated or torn.
• All contaminated cleaning materials — gloves, gowns, wipes, absorbents — go into HD/chemo-labeled waste containers, never general trash.
