9.3 Task-Based PPE Selection

Task-Based PPE Selection

Not every hazardous drug task carries the same PPE requirement, and treating every task identically — either over-protecting routine tasks or under-protecting higher-risk ones — is both a real-world safety issue and a heavily tested exam concept. USP <800> allows facilities to calibrate PPE to the task through a documented Assessment of Risk (AoR), but that calibration only works in one direction: it can justify a reduced PPE tier for certain low-manipulation tasks, and it can never excuse skipping the baseline minimum of at least one pair of ASTM D6978-tested chemo gloves for any task that contacts an HD.

The Assessment of Risk (AoR)

An AoR is a facility's documented, drug-by-drug and task-by-task analysis of manipulation, dosage form, packaging integrity, frequency, and quantity handled. It allows alternative (typically reduced) containment strategies or PPE for specific low-risk tasks and drugs meeting defined criteria — but AoR-based reductions do not apply to sterile or nonsterile compounding, which always require full PPE regardless of what an AoR concludes for other tasks involving that same drug.

Matching PPE to the Task

The pattern to notice: receiving and simple counting sit at the low end of the manipulation spectrum and may use single gloving; anything that involves compounding, manipulating, or generating aerosols or particles sits at the high end and always requires double gloving plus a gown, with sterile compounding adding garb on top. Administration sits in between — always gloved and gowned, with a CSTD reducing (not eliminating) the exposure pathway when the dosage form allows a closed connection.

Why "It's Just Counting" Is a Trap

A common exam distractor implies that counting a handful of intact oral tablets — say, tamoxifen or methotrexate — needs no special PPE because nothing is being opened, crushed, or reconstituted. This reasoning fails on two counts. First, oral HD tablets and capsules can carry surface drug residue from manufacturing or blister-pack handling even when intact, so bare-hand contact remains an exposure risk. Second, no special PPE is never a compliant answer for any HD-contact task — the true floor, even for the lowest-risk task on the table, is at least one pair of ASTM D6978-tested chemo gloves. An AoR can justify skipping the second glove or the gown for simple counting; it cannot justify skipping gloves altogether.

Why Compounding Never Gets an AoR Reduction

Sterile and nonsterile compounding involve direct manipulation of the drug itself — measuring, mixing, drawing up, or reconstituting — which is the highest-exposure-potential activity in the HD workflow. Because of that, compounding sits outside what an AoR can reduce: double gloves and a gown (plus sterile garb for sterile compounding) are required regardless of what the facility's risk assessment concludes for other tasks with that same drug. A technician cannot point to an AoR that reduced PPE for receiving a drug and use it to justify reduced PPE for compounding that same drug — the AoR's scope is task-specific, not drug-wide.

Exam Scenario

A technician receives a sealed, undamaged carton of injectable hazardous drug vials and, per the facility's Assessment of Risk, wears a single pair of ASTM D6978-tested chemo gloves to unpack and shelve them. Later that shift, the same technician is asked to compound one of those same vials into a sterile IV admixture inside a CACI. She reaches for a single pair of chemo gloves again, reasoning that the AoR already covered this drug. Is she correct?

No. The AoR that justified single gloving for receiving does not carry over to compounding. Compounding requires double chemo gloves and a chemo gown (plus sterile garb) regardless of any reduced-PPE determination made for a different, lower-manipulation task involving the same drug.

Key Takeaways

• An Assessment of Risk (AoR) can justify reduced PPE for specific low-manipulation tasks, but it can never eliminate the baseline minimum of at least one pair of ASTM D6978-tested chemo gloves for any HD-contact task.
• Receiving, storage, and simple counting of intact final dosage forms may use single chemo gloving per facility SOP/AoR.
• Sterile and nonsterile compounding always require double chemo gloves plus a chemo gown, regardless of what an AoR concludes for other tasks with the same drug.
• Administration requires chemo gloves (often double per SOP) and a gown; a CSTD reduces but does not replace the PPE requirement when the dosage form allows one.
• An AoR reduction is task-specific, not drug-wide — a reduced-PPE determination for receiving does not carry over to compounding the same drug.
