 Soldering Safety and Guideline

Soldering as a process is the physical linking of two pieces of metals using a filler metal, known as solder, which has a low melting point lower than the melting point of the work piece.

This guidance consolidates good control practice and reinforces existing knowledge with supplementary material.

Thermal, inhalation of toxic vapors from soldering (tin, lead), exposure to heavy metals (tin, lead). In addition, flux containing rosin produces solder fumes, which can cause eye and upper respiratory tract irritation

General Safety Precautions


Lead exposure

Lead (Pb) is a known neurotoxin and can pose other significant chronic health effects, therefore solder containing lead is considred toxic. Potential exposure routes from soldering include ingestion of lead due to surface contamination. Gloves should be worn when handling lead solder, it is recommended to wash hands properly after use. 

Rosin exposure

Flux containing rosin (also called colophony) produces solder fumes that, if inhaled, can result in occupational asthma or make existing asthmatic conditions worsen. The fumes can also cause eye and upper respiratory tract irritation. Avoid inhalation of soldering smoke/fumes. The smoke formed during soldering is mostly from the flux. . To Exposure can be reduced by performing work in a well-ventilated area. Avoid breathing fumes/smoke by keeping your head to the side of, not above, your work. The addition of a small fan that blows from behind the worker across the work area can help move fumes away from the breathing zone

 Soldering Iron Safety

The soldering element should never be touched, tip is about 400°C it is a burn hazard. To the extent possible, conduct soldering on a solid, level surface and always return the soldering iron to its stand when not in use. Soldering iron should not be placed down on workbench.

Solder, Flux and Cleaners

Follow manufacturer’s instructions and read and understand the Safety Data Sheets (SDS) for all materials before beginning work. Cleaning solvents should be kept in dispensing bottles. Hands should be washed after soldering

Fire Prevention

Work should be performed on a nonflammable surface that is not ignitable. Nonflammable clothing that covers arms and legs should be worn to help prevent burns. Secure soldering iron unit in its stand so it cannot inadvertently dislodge onto the work surface. Know where the nearest fire extinguisher is and how to use it.

Electrical Safety

It is prudent practice to use soldering units that are UL (or equivalently) listed. Equipment and cord should be visually inspected before each use. A Portable Appliance Testing (PAT) should also be performed where applicable and within a year to ensure unit is safe for use. Any defect noticed, should be reported and unit locked out and placed out of service.

 Personal Protective Equipment (PPE)

Eye protection, safety glasses, or appropriate goggles / face shields.

·         Gloves.

·         Lab coat.


·         Closed toed shoes.
