How 300 home care workers gained greater safety in just six months
Within six months, more than 300 employees at Skellefteå municipality were onboarded to a modern personal alarm system from Crystal Alarm, connected directly to the SOS Alarm emergency response centre.

The result? Faster activation, simpler administration, and a noticeably safer working day for staff who work alone in sometimes challenging environments.
