🔍 Key Concepts

• RADAR transmitter safety precautions when operating near a pier or terminal • The effect of radio-frequency (RF) energy on people and on certain types of cargo/equipment • Which options describe realistic, standard practices vs. obviously impractical or incorrect ones

💭 Think About

• Ask yourself which option reflects a specific, recognized hazard associated with turning on a RADAR set, especially in port or during cargo operations. • Consider which choices mention something that RF radiation can realistically affect, and which ones are unrelated to normal RADAR operation. • Think about standard shipboard procedures: which action would typically be written into port or terminal safety rules for starting transmitting equipment?

✅ Before You Answer

• Eliminate any option that describes something physically impossible or nonsensical for a magnetron or RADAR set. • Consider whether you are more concerned about personnel exposure or interaction with sensitive/explosive materials when energizing high‑power RF equipment. • Verify which action is commonly tied to safety around flammable/explosive operations rather than a special notification requirement to authorities.
