Soldering Safety

Flux fume, lead, burns and the habits that keep a soldering bench safe

Duration: 1 hour
Modules: 3
Final exam: 70% to pass
Certificate: No expiry

$59

Before you buy: what your employer must also provide

Your employer must assess your actual exposure (for tin-lead solder, the initial lead determination under 29 CFR 1910.1025(d)), select your PPE, train you on its own fume extraction and equipment, and cover its solders and fluxes in site hazard communication training. Where lead exposure is at or above the action level, the employer's lead training program must be repeated every year.

About this course

Soldering looks harmless: a small iron, a thin wire and a wisp of smoke. But the smoke from rosin flux is a recognized cause of occupational asthma, tin-lead solder puts lead on your hands every shift, and solder pots and wave machines hold kilograms of metal hot enough to cause deep burns. This course teaches the hazards and the controls that work.

You will learn what solder fume is made of, why colophony (rosin) fume is a respiratory sensitizer, the symptoms to report, and how to position, check and maintain fume extraction. You will learn how lead from tin-lead solder reaches the body, the action level and permissible exposure limit in the OSHA lead standard, 29 CFR 1910.1025, the hygiene rules that stop lead reaching your mouth, the status of lead rulemaking including the stricter Cal/OSHA limits in force since 2025, and what changes with lead-free alloys. The final module covers iron safety, solder pots and wave soldering, why moisture and molten solder must never meet, the difference between ESD grounding and electrical safety grounding, eye protection and housekeeping. Scenarios come from defense, medical device and industrial electronics assembly.

The course pairs with the PlanetISO ESD Awareness course for static control and J-STD-001 Essentials: Soldered Electrical and Electronic Assemblies for workmanship requirements.

What this course does not cover. It is general awareness training. Your employer must still assess the hazards of your actual work and select PPE, determine whether anyone's lead exposure reaches the action level, provide hazard communication training on the solders and fluxes at your site, and give you hands-on instruction on your extraction equipment, solder pots and wave machines. This course does not make anyone OSHA certified, and OSHA does not approve training providers. State-plan states may have additional or stricter requirements, and employers outside the US follow their own regulations.

The course closes with a 10-question examination drawn from a bank of 20. On passing you receive a PlanetISO Certificate of Completion for the online instruction, with lifetime access to the course. The certificate does not expire.

What you will be able to do

Explain what solder fume consists of and why rosin (colophony) flux fume can cause occupational asthma.
Position, check and report faults in fume extraction equipment.
Describe how lead from tin-lead solder reaches the body and apply the hygiene rules that prevent it.
State the action level and PEL in 29 CFR 1910.1025 and the current status of lead rulemaking, including stricter state limits.
Compare tin-lead and lead-free solder hazards.
Use irons, solder pots and wave equipment without burns, and distinguish ESD grounding from electrical safety grounding.

Prerequisites

None. The PlanetISO ESD Awareness course is a useful companion.

Questions

Does this course meet OSHA lead training requirements?

No. Where exposure is at or above the action level, 29 CFR 1910.1025(l) requires a specific lead training program covering the site's operations, monitoring, medical surveillance and controls, and the employer must make the standard and its appendices available. This course provides general awareness of lead in soldering. Your employer determines whether the lead standard's training program applies and delivers it. For employees at or above the action level, 1910.1025(l)(1)(iv) requires that program to be repeated at least annually; for other employees the standard sets no refresher interval, so this certificate does not expire.

Is the information on lead limits current?

Yes, as of 2026. Federal OSHA limits are an action level of 30 µg/m³ and a PEL of 50 µg/m³. OSHA's 2022 advance notice on lead has not led to a proposed rule. Cal/OSHA adopted an action level of 2 µg/m³ and a PEL of 10 µg/m³ from 1 January 2025, and other state plans may follow. Check the rules for your state.

Will I be OSHA certified after this course?

No. OSHA does not certify workers in soldering safety and does not approve training providers. You receive a PlanetISO Certificate of Completion for the online instruction.

Does the course teach how to make good solder joints?

No. It covers safety. Workmanship requirements are covered in the PlanetISO J-STD-001 Essentials: Soldered Electrical and Electronic Assemblies course.

Does it cover ESD?

Only where ESD and electrical safety overlap, such as wrist strap resistors and grounded irons. The PlanetISO ESD Awareness course covers ESD control in full.

What happens if I fail the exam?

You have 3 attempts. Each attempt draws a different 10-question set from the bank of 20, and module quizzes can be retaken without limit to prepare.
