+ +--- + +## Activity and Persons at Risk + +| Field | Details | +|---|---| +| **Activity Description** | Operation of the Fyla Iceblink Supercontinuum Fiber Laser as a broadband filtered light source within the photonic lantern wavefront sensing optical setup. The laser output is coupled into the optical setup via a single-mode fibre output and may be used in enclosed (fully fibre- or optic-coupled) or free-beam configurations. Optical bandpass filters are used to select specific spectral bands from the supercontinuum output. The system includes a key-switch interlock and laser emission indicator. | +| **Persons at Risk** | Trained laser operators; postgraduate research students; postdoctoral researchers; visiting researchers; laboratory technical staff. | +| **Persons Excluded** | Untrained personnel; members of the public; persons under 18 years of age; pregnant persons (unless risk assessed separately by the University Occupational Health unit). | + +--- + +

+ +--- + +## Hazard Assessment Table + +> **Laser Classification Note:** The Fyla Iceblink emits a **supercontinuum output spanning approximately 450 nm to 2400 nm** (visible to mid-infrared), with peak power outputs in the kilowatt range (pulsed) and average power up to approximately **1 W** depending on configured output and spectral filtering. Without filtering, the unfiltered output at the fibre tip constitutes a **Class 4 laser hazard**. Filtered outputs may reduce the class rating for specific configurations, but this MUST be verified by calculation using AS/NZS IEC 60825-1:2022 methodology before any change in PPE requirements is made. All work MUST be treated as a Class 4 laser hazard unless a formal reclassification has been completed and documented. + +| # | Task or Scenario | Hazard/s | Associated Harm | Existing Risk Controls | Current Risk Rating | Additional Controls Required | Residual Risk Rating | +|---|---|---|---|---|---|---|---| +| 1 | **Direct or reflected beam exposure to the eye – free-beam operation (unfiltered or pre-filter beam path)** | Class 4 optical radiation (450–2400 nm supercontinuum); direct, specularly reflected, and diffusely scattered beam at fibre output tip and any free-beam section prior to filtering optics | Immediate and permanent retinal injury (photochemical and thermal burns); corneal burns from infrared components (>1400 nm); loss of sight in one or both eyes; injury from a single brief exposure | Key-switch interlock preventing unauthorised laser activation; laser emission indicator on front panel; laser warning labels (Class 4) affixed to unit and optical table; laboratory laser warning sign on entry door with emission status indicator; nominal ocular hazard distance (NOHD) established for the setup; Laser Safety Officer (LSO) registered with the University | **Very High** (Likelihood 4 – Likely; Consequence 5 – Catastrophic) | 1.

Nitrile or equivalent non-reflective gloves MUST be worn when hands are in proximity to any beam path. 3. All beam paths MUST terminate in appropriate beam dumps rated for the incident power and spectral range. 4. Specularly reflective items (watches, rings, polished tools) MUST be removed or covered before entering the laser-controlled area. | **Low** (Likelihood 1 – Rare; Consequence 4 – Major) | +| 3 | **Laser emission during optical alignment of free-beam or filter components** | Unintended beam exposure during manual positioning of mirrors, lenses, fibre couplers, or bandpass filters in the beam path; Class 4 optical radiation at all wavelengths from 450–2400 nm | Eye injury (irreversible); skin burns; exposure of bystanders if beam direction is altered unexpectedly | Key-switch interlock (operator-controlled); laser emission indicator on unit; laser warning signage; trained operators only | **Very High** (Likelihood 4 – Likely; Consequence 5 – Catastrophic) | 1.

Any contamination or damage MUST be cleaned or reported before laser operation. 2. Fibre end-face cleaning MUST follow a documented procedure: dry wipe first (lint-free IPA-free wipe), then wet wipe (fibre-grade IPA, ≥99.5% purity), then re-inspect. 3. Fibre connectors MUST only be mated with compatible, clean, and undamaged mating connectors or adaptors. NEVER force-mate a damaged connector. 4. The fibre MUST NOT be bent below the manufacturer-specified minimum bend radius (refer to Iceblink manual Section on fibre handling). 5.

Even in the enclosed configuration, appropriate laser safety eyewear MUST remain accessible and worn when the enclosure integrity cannot be visually confirmed. | **Very Low** (Likelihood 1 – Rare; Consequence 4 – Major) | +| 6 | **Spectral filter failure or incorrect filter installation resulting in unfiltered beam transmission** | Failure, omission, or incorrect installation of bandpass filter in the beam path; unfiltered supercontinuum (450–2400 nm, up to ~1 W average power) transmitted to downstream optics or sample | Eye and skin injury from broadband high-power optical radiation; thermal damage to downstream optics not rated for full supercontinuum power; fire or equipment damage | Bandpass filters specified for experimental setup; visual inspection of filter mount before operation | **High** (Likelihood 3 – Possible; Consequence 4 – Major) | 1. A checklist (included in the SOP) MUST be completed before each experiment, explicitly confirming filter type, orientation, and secure mounting. 2. Filters MUST be labelled with centre wavelength and FWHM; incorrect filters MUST be stored separately from in-use filters. 3. Downstream power at the filter output MUST be measured at first use of any new filter configuration and recorded; this reference value is used to detect filter omission or failure. 4. Filter mounts MUST be mechanically secured (e.g., clamped, screwed) to prevent accidental dislodgement. 5. Thermal power meters rated for the full supercontinuum spectral range MUST be used when characterising filtered output; photodiode-based detectors may have spectrally limited response and MUST NOT be used for total power measurements. | **Low** (Likelihood 1 – Rare; Consequence 4 – Major) | +| 7 | **Electrical hazard – mains power supply and internal high-voltage components** | Mains electrical supply (240 V AC, 50 Hz) to the Fyla Iceblink chassis; internal pump laser drive electronics operating at high voltage; capacitor banks or pulsed electronics within the unit (per Fyla Iceblink architecture) | Electric shock (potentially fatal); arc flash; burns from electrical arc; ignition of flammable materials from electrical fault; electromagnetic interference with sensitive equipment | Fyla Iceblink supplied with IEC-rated mains cable and chassis earth; unit designed and certified to applicable IEC electrical safety standards; internal components are inaccessible without tools; fused IEC inlet on rear panel; laboratory fitted with RCD-protected circuits | **High** (Likelihood 2 – Unlikely; Consequence 5 – Catastrophic) | 1.

Clean using an approved fibre cleaning tool (e.g., fibre cleaning swab or click cleaner). Dispose of used cleaning swabs in general waste. + +5. **Remove and store** any alignment aids, beam blocks, or test components used during the session. + +6. **Return all tools** to their designated storage locations. + +7. **Leave the optical bench in the standard operating configuration** or in the supervisor-specified state for the next session. + +### 7.2 Waste Types and Disposal + +| Waste Type | Description | Disposal Method | +|---|---|---| +| Lens tissue / optical cleaning materials | Solvent-contaminated if IPA used | If contaminated with isopropanol (IPA): allow to evaporate fully in a fume cupboard before disposal in general waste. Quantities of >250 mL of IPA: dispose as chemical waste. | +| Fibre cleaning swabs | Contaminated with fibre cleaning solvent | Allow solvent to evaporate, dispose in general waste. | +| Damaged fibre sections | Silica glass fibre fragments | **Hazardous — puncture risk.** Seal in a rigid container (e.g., plastic bottle with lid) labelled "Broken Glass — Silica Fibre". Dispose in sharps/glass waste stream as directed by University waste management. | +| Damaged optical filters | Glass / coated optical elements | Broken glass: seal in rigid container, dispose in glass waste stream. Intact damaged filters: consult supervisor for special optical material disposal. | +| Worn or degraded laser safety eyewear | Plastic / polycarbonate lens | Dispose in general waste. Remove from service and record disposal in equipment register. | +| Packaging and cardboard | Consumable packaging | General recycling. | + +> **Hazardous Waste:** If any chemical reagents, solvents, or coated materials are used in conjunction with this laser, consult the relevant SDS and the University of Sydney hazardous waste disposal procedure. Do not mix chemical waste streams. + +--- + +## 8. References + +1.
