**Public Safety Bulletin**

**Immediate Attention Required: AC Ripple Hazards in Medical Mobility Devices**
Recent reports indicate that touchable metal surfaces on certain medical mobility devices—including patient lifts, power chairs, electric wheelchairs, and Acorn stairlifts—may emit dangerous levels of **AC Ripple (alternating current ripple)**. Testing has revealed levels up to **100 times higher** than the safety limits outlined in the **National Electrical Code (NEC)**, particularly when a patient’s skin is damp, significantly increasing conductivity and risk of harm.
**What is AC Ripple?**
AC Ripple refers to residual alternating current that can “ride” on direct current (DC) power systems. Excessive AC Ripple can lead to unintended electrical transfer through conductive surfaces, posing serious health risks.
**Affected Devices**
- Patient lifts
- Power chairs & electric wheelchairs
- Acorn stairlifts
- Other motorized medical mobility equipment

**Acute Health Consequences of AC Ripple Exposure**

1. **Electric Shock**: Immediate, painful shocks, even at low voltages, due to damp skin lowering body resistance.
2. **Muscle Spasms/Tetanus**: Involuntary contractions, potentially causing falls or injury.
3. **Burns**: Thermal burns at contact points from sustained current.
4. **Cardiac Arrhythmia**: Severe cases may disrupt heart rhythm, posing life-threatening risks.
5. **Respiratory Distress**: Muscle paralysis affecting breathing in extreme scenarios.
**Chronic Health Consequences**
1. **Nerve Damage**: Prolonged exposure may impair nerve function, causing numbness or tingling.
2. **Chronic Pain**: Persistent musculoskeletal pain from repeated minor shocks.
3. **Cardiovascular Strain**: Long-term stress on the heart and circulatory system.
4. **Psychological Trauma**: Anxiety or PTSD from recurrent shock incidents.
5. **Skin Conditions**: Dermatitis or lesions at frequent contact points.
**Vulnerable Populations**
Individuals with pacemakers, implanted medical devices, or pre-existing conditions (e.g., diabetes, neuropathy) are at **heightened risk**.

**Recommended Actions**

1. **Immediately Discontinue Use** if shocks, tingling, or unusual sensations occur.
2. **Test Equipment**: Have devices inspected for AC Ripple by a qualified technician.
3. **Mitigation**: Install NEC-compliant attenuation systems to reduce AC Ripple.
