* The UK’s established safe limit for SAR (Specific Absorption Rate) is 2 W/kg. This means that any mobile phone or other wireless device must not emit more than 2 watts of electromagnetic energy per kilogram of body tissue.
** IP67 dust-tight and protected against short-term submersion in water up to 1 meter for a maximum of 30 minutes.
*** Maximum battery life consumption (in hours) was recorded on a new device using the default configuration and a static location, with automatic position settings disabled. Actual battery life may vary significantly depending on device configuration and real-world usage.
Are the devices safe to use?
All devices conform to relevant UK and EU electronic device specifications, having secured the mandatory UKCA and CE certifications to ensure safe and legal operation.
Peoplesafe devices use similar technologies to mobile phones for communication and magnetic charging.
Pacemakers
Due to the variety of pacemakers and heart conditions, we cannot provide specific medical advice regarding the impact of Peoplesafe devices on individual health.
- We recommend consulting the latest NHS guidelines, which currently advise keeping mobile phones and wireless devices at least 15cm away from pacemakers.
- Due to the comparatively low maximum SAR values, Peopleasfe devices should not impair the performance of implanted pacemakers.
- If you are in any doubt, seek advice and clarification from a doctor and/or the manufacturer of the specific pacemaker.
- A thorough risk assessment should consider all relevant factors, including potential medical implications. It is the employer's responsibility to conduct this assessment for their staff.
