How to Avoid Lead Fumes When Soldering

Lead, when heated enough, can give off poisonous fumes. Though lead-free solder is becoming more widely used, you can still find older lead solder in existing electronics and radiators. There are ways to protect yourself from the lead fumes.

Difficulty: Easy

Instructions

1. Use lead-free solder. However, the soldering and flux may still produce potentially-harmful smoke.

2. Hold your breath while the solder is smoking.

3. Avoid using excessive solder and don't burn the solder for long periods.

4. Work in a ventilated area with open windows and doors. Don't let the fumes and lead spread into other areas of the building.

5. Place a fan near your workstation to keep air circulating.

6. Wear a respirator if you plan to solder for an extended period. Ensure that the respirator is rated for lead particulate and fume protection.

7. Install a ventilation system if heavy soldering is routinely scheduled for your workshop or if you are working with radiators. A fume extraction system can remove lead fumes and dust from your work area.

8. Make sure that your melting pot has a thermostat that regulates the temperature, if you're melting dross. The temperature should be kept close to 620 degrees F, the melting point of lead. As lead approaches 900 degrees F, it produces fumes.

Tips & Warnings

• Don't use a soldering gun that's too powerful for the job. Never leave your soldering iron plugged in and unattended.
• Replace your soldering iron if the cable becomes worn or gets burnt.
• Change your cloths and wash your hands and tools after working with lead. Keep your work area clean of lead filings.
