Our compounding pharmacy customers are reviewing proposed new guidelines, USP <800> Hazardous Drugs—Handling in Healthcare Settings, for compounding hazardous drugs (HD).
Hazardous drugs are a category of pharmaceutical products that can harm the people who prepare them even though they are designed to have a therapeutic effect on the patients who use them.
Included are drugs that are carcinogenic, genotoxic, teratogenic, have reproductive toxicity, or are toxic to organs.
HDs may require either sterile or non-sterile compounding.
Our customers use our Ductless Containment Hoods for non-sterile compounding.
“No acceptable level of personnel exposure to HDs” – USP <800>
USP <800> proposes a separate room for non-sterile HD compounding. No matter which type of hood is used, it must have HEPA filtration and be exhausted to the exterior of the building.
The block diagram below uses the terminology of the proposed USP <800> document.
The drawing below shows how pharmacists who use our Ductless Containment Hood can connect our ductless hoods to existing building ventilation ductwork and contribute to the proposed air-pressure requirements for the room.
The noted line numbers refer to specific lines in the proposed USP <800> standard.
The photo to the right shows a plenum attached to a Model 300 chassis.
Plenums are used to create enclosed chambers within ventilation systems that can affect air pressure within a building or room.
A 6-inch collar on the plenum allows HEPA-filtered air to be exhausted into central exhaust ductwork.
Our plenum is not a special build or a custom product.
We’ve had plenums in our catalog for years because we have customers who need them.
Modular design at its most effective
Modular design can seem like an ephemeral concept – until it solves a problem for you.
Some compounding pharmacists have called to bemoan their earlier purchases of hoods that cannot be modified.
We feel their pain, but we can’t help but acknowledge the diverse customer worlds made available to us due to modular design.
Proposed 12-air-exchanges-per-hour requirement
We think pharmacists should investigate the value of air exchanges as a method for controlling exposure to airborne hazards.
Experts in industrial hygiene don’t favor air exchanges to control exposure.
