CBT Safety & Compliance Standards 3 — Questions and Answers
Question 1: Which FCC regulation requires broadcast stations to maintain a public inspection file, including EEO records and ownership documents?
- 47 CFR 73.3526 (commercial) / 73.3527 (noncommercial) (Correct answer)
- 47 CFR 73.1870
- 47 CFR 73.1560
- 47 CFR 73.1015
Correct answer: 47 CFR 73.3526 (commercial) / 73.3527 (noncommercial)
47 CFR 73.3526 and 73.3527 require commercial and noncommercial stations respectively to maintain online public inspection files.
Question 2: A broadcast engineer discovers the station's Emergency Alert System (EAS) equipment has not been tested in over 60 days. What is the violation?
- Required weekly tests must occur at least once per week (Correct answer)
- Monthly tests are sufficient so no violation has occurred
- EAS equipment only needs testing during actual emergencies
- EAS tests must occur daily
Correct answer: Required weekly tests must occur at least once per week
FCC rules require Required Weekly Tests (RWT) of EAS equipment at least once per week, so missing 60 days constitutes multiple violations.
Question 3: What does the term 'controlled RF environment' mean in the context of FCC RF safety rules?
- Areas where only FCC-licensed personnel may enter
- Locations where occupants are aware of RF exposure and can exercise control over their exposure (Correct answer)
- Any area with RF power density below 1 mW/cm²
- Shielded rooms that contain RF emissions
Correct answer: Locations where occupants are aware of RF exposure and can exercise control over their exposure
A controlled environment under FCC rules is one where workers are aware of RF exposure and can take steps to control their time in that environment.
Question 4: Under OSHA 29 CFR 1910.1200, broadcast facilities storing hazardous chemicals must maintain which documentation for workers?
- Safety Data Sheets (SDS) for all hazardous materials on site (Correct answer)
- FCC Form 302 for each chemical storage area
- EPA Form 7610-1 for each substance
- MSDS submitted annually to the local fire department only
Correct answer: Safety Data Sheets (SDS) for all hazardous materials on site
OSHA's Hazard Communication Standard (HazCom) requires Safety Data Sheets (SDS) to be maintained and accessible for all hazardous materials.
Question 5: A directional AM antenna array requires reauthorization. Which FCC filing is used to request a license modification for antenna pattern changes?
- FCC Form 302-AM
- FCC Form 301
- FCC Form 2100 Schedule A (Correct answer)
- FCC Form 603
Correct answer: FCC Form 2100 Schedule A
FCC Form 2100 Schedule A is used for AM broadcast station license applications, including modifications to directional antenna patterns.
Question 6: What grounding requirement does the NEC specify for broadcast tower guy wire anchors to protect against lightning?
- Guy anchors must be bonded to the tower grounding electrode system (Correct answer)
- Guy anchors only need grounding if the tower exceeds 200 feet
- Guy wires are self-grounding and require no additional electrode
- Guy anchors must be insulated from ground to prevent RF currents
Correct answer: Guy anchors must be bonded to the tower grounding electrode system
NEC requires guy wire anchors to be bonded to the tower's grounding electrode system to safely dissipate lightning energy.
Question 7: Which agency must a broadcast station notify before painting or changing the lighting on a registered antenna structure?
- FCC only
- FAA only
- Both the FCC and FAA (Correct answer)
- State aviation authority only
Correct answer: Both the FCC and FAA
Changes to obstruction marking or lighting on registered antenna structures require notification to both the FAA (via Form 7460-1) and updating FCC antenna structure records.
