CPCT Safety & Compliance Regulations 5 — Questions and Answers
Question 1: Which organization issues the CPCT certification and establishes the competency standards for premises cabling technicians?
- BICSI
- CompTIA
- NCTI (National Cable Television Institute) (Correct answer)
- ETA International
Correct answer: NCTI (National Cable Television Institute)
The CPCT (Certified Premises Cabling Technician) certification is issued by NCTI (now known as the Society of Cable Telecommunications Engineers, SCTE), validating technician competency.
Question 2: When using a fishtape or pull line through conduit, which safety precaution is essential to prevent electrical shock?
- Ground the fishtape to the conduit before use
- Verify the conduit is free of energized conductors before pulling (Correct answer)
- Use only plastic conduit when pulling fishtape near panels
- Wear leather gloves rated for 1000V arc flash
Correct answer: Verify the conduit is free of energized conductors before pulling
Before inserting a fishtape, technicians must verify the conduit does not contain energized conductors, as conductive fishtapes can contact live wires and cause electrocution.
Question 3: Under OSHA's Lockout/Tagout (LOTO) standard, which step must occur FIRST in the energy control procedure before a technician works on telecommunications equipment sharing a power source?
- Apply lockout/tagout devices to energy isolation points
- Notify affected employees of the shutdown
- Identify all energy sources associated with the equipment (Correct answer)
- Release or restrain stored energy
Correct answer: Identify all energy sources associated with the equipment
The first step in OSHA 29 CFR 1910.147 LOTO procedures is to identify all hazardous energy sources before any other control measures are applied.
Question 4: What does a Class C fire extinguisher rating indicate about its suitability for cabling work environments?
- It is effective on ordinary combustibles like wood and paper
- It is safe for use on energized electrical equipment fires (Correct answer)
- It is designed for flammable liquid fires only
- It is rated for metal and chemical fires
Correct answer: It is safe for use on energized electrical equipment fires
Class C rated extinguishers use non-conductive agents (CO2, dry chemical, or clean agent) making them safe to use on fires involving energized electrical equipment.
Question 5: A cabling technician is required to work on a roof to install antenna cabling. At what unprotected edge height does OSHA require fall protection in general industry?
- 4 feet (Correct answer)
- 6 feet
- 8 feet
- 10 feet
Correct answer: 4 feet
OSHA 29 CFR 1910.28 requires fall protection in general industry whenever workers are exposed to falls of 4 feet or more to a lower level.
Question 6: Which NEC article specifically addresses the installation requirements for optical fiber cables and raceways in buildings?
- Article 770 (Correct answer)
- Article 800
- Article 820
- Article 830
Correct answer: Article 770
NEC Article 770 covers optical fiber cables and raceways, including listing requirements, separation from power conductors, and fire-rated assembly requirements.
Question 7: When disposing of cable jacket scraps containing PVC insulation on a job site, what environmental regulation must technicians be aware of?
- PVC cable scraps are classified as universal waste and require special disposal (Correct answer)
- PVC scraps may be burned on-site if quantities are small
- Cable scrap is exempt from all environmental regulations
- PVC cable scraps must be sorted by conductor gauge before disposal
Correct answer: PVC cable scraps are classified as universal waste and require special disposal
PVC cable scraps may contain lead stabilizers or other regulated substances; many jurisdictions classify them as regulated waste or recyclable material with specific disposal requirements under EPA rules.
