Course information

Overview: Electricity from mains power sources has been shown to cause shocks, muscle stimulation, fires and burns. In some cases, these effects have been fatal. Because medical equipment may be designed to come into contact with patients, protection methods and specific parameters defined by standards have been utilized by regulatory bodies. The primary standards come from the International Electrotechnical Commission and cover different classes and types of equipment. These standards require testing using appropriate test equipment and methods. The testing can take place in the healthcare facility under the guidance of biomedical engineering. The video provides this background on standards and test methods with the goal to keep patients and staff safe.

Course duration: Approximately 35 minutes.

Certificates: A Confirmation of Participation is available to participants who complete 100% of the course material.
