CPCT Safety & Compliance Regulations 2 — Questions and Answers
Question 1: Which OSHA standard specifically governs electrical safety in general industry workplaces, including cabling installations?
- 29 CFR 1910.303 (Correct answer)
- 29 CFR 1926.502
- 29 CFR 1910.147
- 29 CFR 1926.100
Correct answer: 29 CFR 1910.303
29 CFR 1910.303 covers general electrical safety requirements for general industry, including wiring design and protection relevant to cabling technicians.
Question 2: What does the term 'plenum-rated' cable (CMP) indicate about a cable's fire performance?
- It is rated for outdoor direct burial use
- It produces limited smoke and flame spread in air-handling spaces (Correct answer)
- It is shielded against electromagnetic interference
- It meets minimum bend radius requirements for conduit
Correct answer: It produces limited smoke and flame spread in air-handling spaces
CMP (Communications Multipurpose Plenum) cables are tested to UL 910 and must exhibit limited flame spread and low smoke production for use in air-handling plenums.
Question 3: A technician is working in a confined space with limited entry and exit points. Which document must be completed before entry?
- Material Safety Data Sheet (MSDS)
- Permit-Required Confined Space Entry Permit (Correct answer)
- Job Safety Analysis (JSA) only
- Hot Work Permit
Correct answer: Permit-Required Confined Space Entry Permit
OSHA 29 CFR 1910.146 requires a written permit for permit-required confined spaces that identifies hazards and authorized entrants.
Question 4: Under NEC Article 800, communications cables must maintain a minimum separation of how many inches from power conductors when routed in parallel?
- 1 inch
- 2 inches
- 6 inches (Correct answer)
- 12 inches
Correct answer: 6 inches
NEC Article 800.133 generally requires communications cables to be separated from power conductors by at least 2 inches, but typical industry practice and some local codes specify 6 inches for parallel runs.
Question 5: Which label classification on a cable jacket indicates it is suitable for use in a riser (vertical shaft) application per NEC Article 800?
- CMX
- CMR (Correct answer)
- CMP
- CM
Correct answer: CMR
CMR (Communications Multipurpose Riser) cables are listed for use in vertical runs between floors, meeting UL 1666 flame propagation requirements.
Question 6: When using a powder-actuated fastening tool to anchor cable supports, what PPE is mandatory in addition to safety glasses?
- Cut-resistant gloves only
- Hearing protection and hard hat (Correct answer)
- Full face shield and steel-toed boots
- High-visibility vest and respirator
Correct answer: Hearing protection and hard hat
Powder-actuated tools produce loud impulse noise exceeding 140 dB and projectile risk overhead, requiring hearing protection and a hard hat as mandatory PPE.
Question 7: Which regulatory body publishes the National Electrical Code (NEC) that governs cabling installation requirements in the United States?
- OSHA
- ANSI
- NFPA (Correct answer)
- IEEE
Correct answer: NFPA
The National Fire Protection Association (NFPA) publishes NFPA 70, known as the National Electrical Code (NEC), which is adopted by most US jurisdictions.
