Chances are, someone in your life has been affected by cancer. And you've seen plenty of pets in your practice battling the
disease. Thankfully, research has given cancer patients hope—and has given you a chance to help the pets you serve. But you
can't let the noble desire to extend the lives of your patients be a source of suffering for you and your team members.

To that end, it's important that you take precautions when handling cytotoxic drugs (CDs). Staff exposure can occur at many
points in the process—during preparation, administration, or cleanup.
When deciding on a method to control or eliminate any safety hazard, the Occupational Safety and Health Administration (OSHA)
expects practice owners to rely on "engineering controls" before the use of procedural policies or personal protective equipment.
The latter steps are necessary, but they don't negate the need for proper facility preparation.
The most basic purpose of these physical safeguards is to control environmental exposure during procedures. Typically, this
exposure comes in the form of splattering, spraying, or aerosol generation of the material. In that vein, environmental controls
are designed to protect not only those team members immediately involved in the procedure, but also others in the area or
who may use the area at a later time. Here are some of the most important issues to address when dealing with CDs:
Segregation: All CDs must be stored and prepared in one centralized area to minimize the risk of "extraneous" contamination throughout
the facility. This means setting aside a room to be used exclusively for chemotherapy procedures. In specialty practices with
oncology services, the room should be large enough to prepare and administer the drugs as well as segregate patients from
common areas during hospitalization. The busy treatment area is the least suitable place for these procedures.
OSHA requires that a biological safety cabinet (BSC) be used for diluting, drawing up, and mixing all dangerous drugs. "Closed
system" drug bottles are a good precaution, but OSHA still requires the use of a BSC.
Signage: You must post warning signs on the door to the chemotherapy area. The signs should identify the room as a CD preparation
area and restrict entry to authorized persons. Spill cleanup procedures should be posted in the room, and you should place
a spill response kit nearby.
Disposal: You must place a yellow sharps container inside the BSC and another in the administration area. A suitable waste collection
container and segregated laundry container must be available in the room.
Emergency preparation: An appropriate eyewash device must be readily available. In this case, it's considered essential that the eyewash device
be in the room where all procedures are performed.
Cleanup: You must take special care when cleaning the chemotherapy room. After each procedure or when cleaning patient cages, the
precautions you've outlined for spill cleanup should be followed. At the end of each day, the entire area should be sprayed
thoroughly with 70 percent alcohol.
Finally, make sure team members aren't smoking, drinking, eating, or applying cosmetics in the preparation area—these activities
greatly increase the risk of exposure.
