Service 21 / 27 · Hazardous Drug Facility Engineering
Containment That Follows the Hazardous Drug from Receiving to Disposal.
Unclear hazardous routes become containment gaps: a package opened in the wrong room, storage without negative pressure, or waste that crosses a clean corridor. ALVEDA engineers hazardous drug facilities around the full journey of the material, from receiving and controlled unpacking through storage, compounding, deactivation and waste dispatch, with the pressure, exhaust, access and segregation measures each step needs. The concept is planned with consideration for applicable pharmacopeial chapters, such as USP <800>, and the project-specific requirements confirmed with the client.

Technical detail
Containment topics
Contents · 11
01 / 11
Receiving & Unpacking
Hazardous deliveries are separated from general receiving before any package is opened.
- Dedicated or segregated hazardous receiving point
- Unpacking in a contained, negatively pressurized space
- Damaged-package handling provision
- Direct route from unpacking to hazardous storage
02 / 11
Negative-Pressure Containment
Hazardous rooms are held negative to their surroundings, with the relationship defined and verified per project.
- Negative rooms and their buffer or ante spaces
- Airflow direction at every hazardous boundary
- Local pressure indication and alarms
- Evidence plan for commissioning and qualification
03 / 11
Hazardous Storage
Storage is kept separate from non-hazardous stock and from preparation areas.
- Dedicated storage room with containment
- Refrigerated hazardous storage where needed
- Separation from general stock and from compounding rooms
- Controlled access and inventory visibility
04 / 11
Access Control & Warning Systems
Only authorized people should reach hazardous rooms, and everyone should know when they are near one.
- Restricted access points and door control
- Hazard warning signage at entries and storage
- Pressure and alarm indication visible to staff
- Emergency egress kept clear of containment routes
05 / 11
Hazardous Compounding Areas
Compounding rooms combine operator protection with product protection where the preparation is sterile.
- Room placement within the negative containment zone
- Containment PEC selection input and exhaust needs
- Entry sequence with physical demarcation for gowning
- Separation of sterile and nonsterile hazardous work
06 / 11
PPE Strategy Interface
The layout gives the client PPE program the space and sequence it needs; PPE selection itself remains with the client safety team.
- Donning and doffing positions in the entry sequence
- Storage for clean PPE at the point of use
- Disposal points for used PPE inside the containment zone
- Coordination with the client PPE and training program
07 / 11
Spill-Response Infrastructure
Spill response depends on equipment being where the spill is likely to happen.
- Spill kit locations in receiving, storage and compounding
- Emergency eyewash and decontamination provisions
- Surfaces and finishes that allow full cleanup
- Clear access for response without crossing clean areas
08 / 11
Deactivation / Decontamination
The facility provides the space, utilities and surfaces the client cleaning program needs to deactivate and decontaminate.
- Wipe-down points for containers leaving hazardous areas
- Cleaning agent storage and preparation space
- Utility provisions for cleaning activities
- Finishes compatible with the selected cleaning agents
09 / 11
Hazardous Waste Flow
Waste leaves by its own route and is never returned through the clean supply path.
- Defined waste route from each hazardous room
- Waste holding and dispatch area
- Destructive autoclave interface where applicable
- Segregation from clean material flow
- Coordination with the licensed disposal interface
10 / 11
Exhaust / Containment Interfaces
Exhaust design is coordinated with HVAC so that contaminated air is filtered and discharged away from intakes.
- Dedicated exhaust for hazardous rooms and PECs where required
- Exhaust filtration requirements defined per project
- Separation of fresh-air intake and exhaust discharge
- Behavior on power or fan failure
11 / 11
Hazardous vs Non-Hazardous Segregation
Segregation is applied consistently across receiving, storage, preparation, packing and waste.
- Separate zones or clearly demarcated areas
- Separate garment and sterilization handling where required
- Packing and labeling kept apart by preparation type
- Laboratory testing of hazardous samples considered separately

- 01
Receiving
Deliveries arrive at a dedicated point, separate from general goods.
- Containment: Sealed outer packaging kept closed; spill kit at the point of receipt.
- 02
Controlled unpacking
Outer packaging is removed in a designated, ventilated area before items enter storage.
- Containment: Local exhaust or a ventilated unpacking station.
- 03
Storage
Hazardous items are stored apart from other materials under controlled conditions.
- Containment: Dedicated, clearly marked storage; refrigerated units where required.
- 04
Compounding
Preparation takes place inside a primary engineering control within a dedicated room.
- Containment: Externally exhausted primary engineering control: containment cabinet or isolator.
- 05
Transfer
Prepared items leave the room along a defined route that avoids crossing clean flows.
- Containment: Sealed, labelled transport containers; pass-through where applicable.
- 06
Deactivation / decontamination
Surfaces and equipment are cleaned with a defined, validated sequence.
- Containment: Finishes and details selected to be cleanable and resistant to agents.
- 07
Waste holding
Sealed waste is held in a secure, segregated area pending collection.
- Containment: Rigid, labelled containers; segregated from general waste.
- 08
Disposal interface
The hand-over point to the licensed waste contractor, outside the controlled areas.
- Containment: Containers stay sealed through collection.

PC-H
Hazardous drug containment cascade
A positive ante room shields the corridor, while the preparation room is held negative so hazardous particles stay in.
–HD buffer room
- Room function
- Houses the containment primary engineering control (C-PEC) used to prepare hazardous drugs.
- Classification
- ISO 7
- Relative pressure relationship
- Negative to the HD ante room — the lowest room pressure in the chain.
- Airflow direction
- Air enters from the ante room and is exhausted to outside, not recirculated to other areas.
- Adjacent spaces
- HD ante room, C-PEC
- Design consideration
- Externally vented, sealed room envelope; monitor the negative step continuously with a local display and alarm.
Selected zone: HD buffer room
Relative relationships only — differential values are set per project.
