Fire & Electrical Safety
Fire Safety
Always have fire extinguishers available for both electrical and non-electrical fires.
In the event of an electrical or chemical fire, use only extinguishers that are specifically labeled
for such purposes. Using water or other liquids can cause fatal or other serious personal injury.
To reduce the risk of electrical shock, try isolating the product, if safe to do so.
Using electrical products in an environment for which they were not designed to be used can
lead to fire or explosion. Apply, observe, and enforce appropriate fire regulations for the type
of medical area being used.
Electrical Safety
• To reduce electrical shock hazards, inspect the scanner face and housing before use.
Discontinue use if the housing is damaged, or if the face is cracked, chipped, or torn.
• All patient-contact scanners not specifically indicated as defibrillation-proof must be
removed from the patient before applying high-voltage defibrillation pulse.
• High-frequency electrical signals from an ultrasound can interfere with pacemaker
operation. Be alert to this unlikely but potential hazard and stop using the system if you
notice it is interfering with a pacemaker.
• Connecting accessories not supplied or approved by Clarius could result in electrical shock.
• Electrosurgical units (ESUs) and other scanners intentionally introduce RF electromagnetic
fields (currents) into patients. Because imaging ultrasound frequencies are within the RF
range, ultrasound scanner circuits are susceptible to RF interference.
