1. Worksite Preparation and Safety
SCTE FCBI-K Domain 1 (12%): permits, right of way and utility locates; traffic control and public safety; Job Hazard Analysis including compressed air and stored energy; PPE; communication; and stop-work decisions.
Key facts
- Before work, verify permits, right-of-way permission and current utility locates. Call 811 or the state one-call center, and respect the ticket's life.
- Work in or near roads needs a traffic control plan following the MUTCD and local permits, with high-visibility apparel.
- A Job Hazard Analysis breaks the job into steps, identifies hazards and assigns controls. Update it when conditions change.
- Compressed air is stored energy: hose whip, ejected fittings or sponges, and sudden release at the duct or head.
- PPE follows the hazard: eye protection against particles at duct ends, hearing protection near compressors, plus gloves, hard hat and high-visibility clothing.
- Pick communication to suit the site: two-way radios for distance and noise; hand signals only with a clear line of sight.
- Stop work immediately on loss of communication, abnormal system behavior or an uncontrolled hazard.
- Vaults and manholes may be confined spaces. Test the atmosphere and keep compressor exhaust away from openings.
Flashcards
Exam tip: Between a faster answer and a safer one, the exam wants the safer one. If people cannot communicate or the system is behaving oddly, stop first.
2. Route Assessment and Equipment Verification
SCTE FCBI-K Domain 2 (14%): reading drawings, work orders and splice plans; calculating route and segment lengths; judging terrain, elevation and bends; and matching equipment and compressor capacity to the route.
Key facts
- Construction drawings, work orders and splice plans define blowing scope, segmentation and constraints.
- Stationing: 58+75 means 5,875 ft from the zero point. Subtract stations to get a segment length.
- Compare planned and observed conditions. A discrepancy that affects feasibility goes to the supervisor or engineer before blowing.
- Bends and elevation change add resistance, and their effect combines. Blowing downhill is preferred where the layout allows.
- Select the launch point and direction that make the hard parts of the route most manageable, within the design.
- Compressors must deliver enough air volume at working pressure, not just reach the pressure.
- Pneumatic drive units draw air too, so add their consumption to the duct demand.
- Altitude and heat can reduce the delivered performance of compressors and hydraulic power units.
Flashcards
Exam tip: Always subtract stations, add field changes, then compare with the expected reach. Most route items are this three-step calculation followed by one decision.
3. Materials Selection and Cable Handling
SCTE FCBI-K Domains 3 (8%) and 4 (10%), 18% together: cable and duct types, fill ratio, compatible lubricants and accessories; reel setup, footage and slack, bend and tensile limits, carriers and grips, exit-site management and climate effects.
Key facts
- Cable construction affects blowing: stiffness, weight, diameter and jacket material. Hard, low-friction jackets generally blow better.
- Stiffer cables resist buckling and do well on straight routes; more flexible cables handle many bends better.
- Fill ratio by diameter is cable OD divided by duct ID. A common guide is about 50 to 75%, with 80% usually the practical upper limit. The manufacturer's limit governs.
- Very low fill raises the risk of the cable curling in the duct, and very high fill cuts airflow.
- Lubricant must be approved for both the jacket and duct, and used in the specified quantity.
- Cable must enter the machine straight and without tension, from a level reel with free payout.
- Bend radius and tensile limits come from the cable data sheet, and dynamic limits are stricter than static ones.
- Figure 8s, fleeters and take-up reels control cable at the exit; keep cable away from dirt, traffic and damage.
- Cold stiffens cable and duct and reduces flexibility; heat softens plastics.
Flashcards
Exam tip: Check which diameter is in a fill question. Duct is sold by OD/ID pairs, and the formula always uses the inner one.

4. Equipment Inspection and Operational Safety
SCTE FCBI-K Domain 5 (10%): blowing system components including safety clips and whip checks; signs of wear, moisture and contamination; airflow and pressure ratings; manufacturer maintenance; and climate effects on equipment.
Key facts
- A system usually includes a compressor, aftercooler or moisture separator, air hoses, a blowing head with drive, duct connection seals and a hydraulic or pneumatic power source.
- Safety clips stop claw couplings from separating; whip checks restrain a hose if a connection fails.
Flashcards
Exam tip: Two questions for any equipment item: is it rated for this load, and is it in safe condition? If either answer is no, it stays out of service.
5. Duct Preparation and Proofing
SCTE FCBI-K Domain 6 (14%): lead-in jumpers, couplers and continuity loops; visual, mandrel, sponge, rod and air proofing; leak and pressure testing and what the results prove; and moisture and environmental effects.
Key facts
- Lead-in jumpers connect the blowing head to the target duct, couplers join sections, and continuity loops carry the air path through intermediate access points.
- Every coupler must be correctly seated and rated, because one leak robs the blow of air.
Flashcards
Exam tip: List each test with what it proves and what it leaves open. Most proofing items ask you to name the remaining risk.
6. Fiber Blowing Operations
SCTE FCBI-K Domain 7 (12%): manufacturer operating limits; single-length versus sectionalized blowing; procedural sequence; monitoring distance, pressure, airflow, hydraulic load and cable movement; and safe pause, shutdown and restart.
Key facts
- Manufacturer limits on pressure, push force, speed and temperature are hard limits. Stay inside them.
- Blowing combines a mechanical push near the entry with air drag along the cable, which reduces friction and tension.
Flashcards
Exam tip: Sequence items usually hide one unsafe step. Find where the head is opened or the air is turned on, and check what must already be true at that moment.
7. Fiber Blowing Troubleshooting
SCTE FCBI-K Domain 8 (10%): recognizing abnormal indicators and cable behavior, separating likely causes of stalled, obstructed or failed operations, and choosing corrective action only after the cause is confirmed.
Key facts
- Stall signature: distance stops or slows while push load rises.
- Leak signature: pressure falls, airflow rises and cable speed drops.
Flashcards
Exam tip: Read the indicators as a set before picking a cause, then pick the action that confirms it. The exam separates diagnosis from correction.
8. Project Handoff Documentation and Compliance
SCTE FCBI-K Domain 9 (10%): tracking installed footage for quality control and billing, jobsite photos and field records, accurate as-builts, and reporting incidents involving injury or damage.
Key facts
- Track installed footage from sequential marks at start and finish, and compare it with the machine counter.
- Footage records support quality control, project handoff and billing verification.
Flashcards
Exam tip: Records must match reality. Any answer that adjusts a number to make it agree, or skips reporting because damage is small, is wrong.
How to pass
- Route assessment and duct proofing are the largest domains at 14% each. Practice reading stationing, computing segment lengths and deciding what each proofing test does and does not prove.
- The objectives are judgment-focused. When a scenario shows abnormal behavior, lost communication or an uncontrolled hazard, the safe answer is usually to stop, depressurize and diagnose before anything else.
- Learn to read indicators together: distance, pressure, airflow, hydraulic load and cable movement. Pressure down with airflow up points to a very different fault than load up with distance stopped.
- You need 38 of 50 correct. Treat the exam as closed book, as SCTE's objectives state, and memorize the formulas for fill ratio, stationing and footage.
