Workplace Safety, Environmental Practices and Documentation
Workplace Safety, Environmental Practices and Documentation
This domain tests safe field behaviour and the records that prove the work was done correctly. It covers laser safety, electrical and height hazards, waste handling and splice documentation.
Core rules and concepts
- Fiber systems use invisible laser light. Never look into a fiber, connector or splicer port. Use an optical power meter or VFL to confirm dead fiber; do not rely on the absence of visible light.
- Wear safety glasses when cleaving or working with bare fiber. Keep fiber offcuts in a labelled sharps container. They can enter skin and eyes and do not decompose.
- Follow electrical safety for powered equipment, use RCD protection where required, and secure ladders. For aerial or confined-space work, use the prescribed harness, gas test and permit system.
- Segregate waste: fiber offcuts, alcohol wipes, packaging, batteries and electronic waste. Follow local rules and the product safety data sheet.
- Documentation includes splice loss records, OTDR traces, fiber assignment, closure labels, as-built drawings and test reports. Record date, technician, wavelength, direction and pass/fail against the limit.
Worked example
A 12-fiber splice job has one splice at 0.45 dB and the rest below 0.10 dB. The acceptance limit for a fusion splice is 0.10 dB. You re-splice the 0.45 dB joint, measure 0.06 dB, and update the splice sheet. You also save the OTDR trace before and after, label the tray and note the rework. The record now explains the change rather than hiding it.
Traps that cost marks
Do not put fiber offcuts in a shirt pocket or ordinary bin. Do not look into a connector to see whether it is working. Do not submit only a final loss number without direction, wavelength and test method. Do not leave labels blank for future technicians.
