Safe Chargers
A common policy among psychiatric wards is that at-risk patients must hand over any chargers. The reason usually given is that the long cables (regardless of their weight bearing capacity) can be used for self-strangulation. Their phones are their lifelines to support and reassurance. Managing the charging of multiple patients' devices is also a significant unnecessary drain on resources.
This problem can be avoided entirely.

Upon admission, loan them one of these instead.
We are starting a pilot program to provide appropriately certified (RCM/CE) and professionally tested/tagged (AS/NZS 3760) chargers with extremely short cables to psychiatric wards which cannot easily be used as any kind of ligature. This includes USB-C, USB-Micro, Lightning and 30 Pin.
We use IKEA SJÖSS 30W chargers. They are readily available, excellent value for money and well regarded by people who do teardowns.
If you are a consumer advocate, or anyone working for a hospital who may be able to contribute towards effecting the required policy changes to make this a reality (or who has concerns), contact us.
All materials and funds used for this are donated.
