- Compromises the protective rating of arc-rated garments
- Melts at ~260 °C
Fire-Resistant Thread Options
- Nomex® (Meta-Aramid):
- Self-extinguishing, non-melting
- Heat resistant up to ~370 °C
- Self-extinguishing, non-melting

Key Australian Standards
- AS/NZS 4836:2023 – Safe working on or near low-voltage installations
- AS/NZS 4502.1 – Protective clothing against heat and flame
- IEC 61482-2 – Clothing for protection against arc flash thermal hazards
- NFPA 70E – US standard for electrical safety in the workplace, covering arc flash PPE performance and safe work practices.
- Important: Any embroidery must maintain the garment’s compliance with these standards.
Best Practice for Safe Embroidery
- Use certified fire-resistant thread only
- Ensure backing and bobbin materials are also flame resistant
- Maintain proper stitch density and needle selection to protect fabric integrity
- Follow industrial laundering guidelines to maintain thread performance
