Pod Battery Disposal
The pods contain batteries that require safe handling.
They may leak or explode if exposed to heat or
disposed of improperly. Dispose of the batteries in
accordance with applicable federal, state and local
regulations as applicable in the United States of
America, or equivalently as may be applicable in
other countries.
Within the European Union, disposal of small amounts
of portable batteries to landfills and incinerations are
allowed under the Batteries Directive 2006/66/EC
and Member State regulations. Alternate instructions
for safe battery removal to waste disposal is also
possible but requires special decontamination steps
as follow:
For safe battery removal at the end-of-life by a
waste treatment facility, infected units should be
decontaminated as per hospital procedure. However,
lithium battery risks (e.g. do not expose to autoclave
because of risk of explosion) should be considered
before they are sent for recycling. Instructions for
decontamination are provided below. If it is not
possible to decontaminate the pods before recycling,
the hospital should not attempt to remove the
batteries from the waste. Disposal of small amounts
of portable batteries to landfills and incinerations are
allowed under the Batteries Directive 2006/66/EC
and Member State regulations.
Prior to sending electronic waste for recycling, the
pods are required to go through a complete cleaning
and disinfection cycle. The following steps are
recommended:
1. The pod’s outer surfaces are wiped down first.
2. Remove the back cover (flexible) from the pod.
Separate a corner or side of the back cover from
the body using a flat screwdriver to allow the
complete back cover to peel off in order to expose
the undersurface. The exposed opening of the
undersurface will allow the inner portions of the
pod to be exposed to the sterilization gas for safe
disposal per the following step.
3. Expose the pod to an Ethylene Oxide (ETO)
sterilization cycle per the following parameters:
a. Preconditioning set points:
- Temperature: 55˚C
- Relative humidity: 55%
- Vacuum set point: 2.61 pounds per square inch
- Preconditioning time: 30 minutes
b. Exposure:
- Temperature: 55 ˚C
- Relative humidity: 55%
- EO gas concentration: 725 mg/L
- 100% EO gas
- Gas exposure time: 60 minutes
c. Aeration:
- Aeration time: 8 hours
- Aeration temperature: 51-59˚C
