electrical, radiation, and laser safety
exam questions and answers
electrical safety - Correct Answers -Electricity has long been recognized as a serious
workplace hazard.
• Injuries can occur from electrical arc flash and arc blast.
• Electrical energy is everywhere and, too often, we take this for granted.
• Only a tiny amount is needed to cause an electrocution.
• Each facility has a safety plan to promote electrical safety.
electrical shock - Correct Answers -- Direct contact with electricity.
- The human body is a good conductor
of electricity.
- Exposure can feel subtle, like a mild tingle.
- Effects can range from a mild tingle to immediate cardiac arrest.
electrical arc flash - Correct Answers -- The light and heat produced as part of an arc
fault.
- A type of electrical explosion or discharge that results from a connection through air to
ground.
- Can be seen and can cause serious burns.
- Can occur from a low and high voltage source.
- Can cause thermal injuries (i.e. burns).
C-arm - Correct Answers -The name derives from the c-shaped arm used to connect
the x-ray source and x-ray detector to one another.
C-ARMs have 2D radiographic capabilities, though they are used primarily for
fluoroscopic intraoperative imaging during surgical, orthopaedic, and emergency care
procedures.
C-ARMs are used in the O.R. (vs. traditional x-ray) because they are quite portable.
o-arm - Correct Answers -O-ARMs have 2D and 3D radiographic capabilities.
They are used primarily for fluoroscopic intraoperative imaging during surgical,
orthopaedic, and emergency care procedures.
O-ARM is a portable CT scanner.
Many O-ARMS offer enhanced connectivity to other capital equipment to enhance
accuracy in surgery (i.e. spine and neurosurgery) through navigation enhancement.
