Soldering Operations

The Soldering Operations SOP (SOP-WLD-002) outlines critical safety procedures to mitigate risks associated with soldering processes. It covers hazards such as burns, eye injuries, inhalation of harmful fumes, and lead exposure, ensuring compliance with relevant workplace health and safety legislation. This document is crucial for electrical technicians and any personnel involved in soldering work, promoting a safer working environment and reducing the likelihood of accidents.

• Burns from soldering iron tip (typically 350–450 °C) and hot solder splash → severe burns
• Eye injury from solder splash, flux spit, or rosin spit → corneal damage
• Inhalation of solder flux fume (rosin/colophony) → occupational asthma, sensitisation
• Lead exposure from leaded solder and contaminated surfaces → neurological, reproductive harm (especially children)
• Fire or explosion from torch flame igniting timber, insulation, or flammable atmospheres → fatality, asset loss
• Burns and asphyxiation from butane or propane cylinder leak
• Electric shock when soldering live circuits (improper isolation)
• Carbon monoxide build-up in poorly ventilated areas during torch use

• Work Health and Safety Act 2011 (Cth) and applicable state/territory WHS legislation
