Soldering Safety - Hazards of Soldering Fumes and Fume Extraction Systems
- 1. Soldering Safety Health Hazards & Fume Extraction Solutions
- 2. Soldering uses heat to join two metals together by melting a third metal or solder material. What is Soldering? Fumes are produced from: • Metal Solder • Solder Flux (aids bonding process) Sentry Air Systems • www.sentryair.com
- 3. Soldering Applications • Fixing Circuit Boards • Manufacturing Electronics • Crafting Jewelry • Metalwork • Stained Glass • Roofers • Plumbers • Gutter Repairs • Electricians Sentry Air Systems • www.sentryair.com
- 4. What are Solder Fumes? Solder (low-melting point metals) heated up releases metal vapors Solder Flux turns into gaseous state to aid bond releases gases Sentry Air Systems • www.sentryair.com
- 5. Soldering Fumes Health Effects Occupational Asthma • Develops from workplace exposure • Sensitized to certain substances • Symptoms: – Chest Tightness – Wheezing – Shortness of Breath Sentry Air Systems • www.sentryair.com
- 6. Soldering Fumes Health Effects Depends on: • Type of Solder – Lead (Lead & Tin) – Rosin-Core – Lead-Free (Tin, Silver, Copper) Lead Solder Rosin-Core Solder Lead-Free Solder Rosin FluxFluoride Flux • Chemical Composition of Solder Flux – Fluorides – Rosin-Based Sentry Air Systems • www.sentryair.com
- 7. Lead Solder Health Effects • May cause: – Lead Poisoning – Kidney Disease – Hypertension – Weight Loss • Targets: – Gastrointestinal Tract – Nervous System – Kidneys – Blood • Symptoms include: – Metallic Taste in the Mouth – Nausea & Vomiting – Headaches – Cramps – Nervousness & Insomnia Headaches Kidney Disease Metallic Taste in Mouth Nervousness & Insomnia Targets the Nervous System Weight LossCramps Hypertension Nausea & Vomiting Targets Gastrointestinal Tract Targets Kidneys Lead Poisoning Targets The Blood
- 8. Lead-Free Solder Health Effects • Tin – Generally Harmless – May Cause Benign Pneumoconiosis – Eye, Skin, and Respiratory System Irritation • Silver – Throat Irritation – Blue Gray Eyes – Nasal Septum Irritation – Gastrointestinal Disturbance • Copper – Eye and Upper Respiratory Irritation – Metal Fume Fever • Fever, Chills, Aches, Pains, Nausea, and Dizziness Fever Dizziness Eye Irritation Blue Gray Eyes Nasal Septum Irritation Throat Irritation Aches, Chills, & Pains Respiratory Irritation Benign Pneumoconiosis Nausea Gastrointestinal Disturbance Skin Irritation
- 9. Specialized Solder Health Effects • Beryllium – Classified as a Group 1 carcinogen. Can lead to beryllium sensitization possibly causing chronic beryllium disease with symptoms of shortness of breath, coughing, fatigue, night sweats, and fever. Can worsen over time forming granulomas or masses of immune cells on the lungs • Aluminum – May provoke irritation to eyes, skin, respiratory system • Gold – Regarded as generally harmless but exercise caution with certain alloys • Iron – May lead to siderosis a form of pneumoconiosis • Brass (zinc oxide) – Can cause metal fume fever (Fever, Chills, Aches, Pains, Nausea, and Dizziness) Dizziness Eye Irritation Coughing Aches, Chills, & Pains Respiratory Irritation Siderosis Nausea Night Sweats Skin Irritation Fever Shortness of Breath Fatigue Granulomas
- 10. Flux Fumes Health Effects • Fluoride Based – produces Hydrogen Fluoride and Boron Trifluoride – Eye, Skin, Nose, and Throat Irritation – Pneumonitis – Bronchitis and Pulmonary Edema • Rosin Based – from Resins of pine trees – Particulate • Lung Damage • Occupational Asthma – Gases • Upper Respiratory Irritation • Possible Cancer Formation Throat IrritationEye Irritation Upper Respiratory Irritation Nose Irritation Pulmonary Edema Lung Damage Skin Irritation Bronchitis Cancer Occupational Asthma Pneumonitis
- 11. Soldering Safety OSHA • OSHA legally requires employers to: – Monitor Air Quality – Restrict exposure – Must stay below Permissible Exposure Limit (PEL) • Use Ventilation to prevent exposure – Local exhaust ventilation – Fume Extraction systems – Best way to prevent exposure • NIOSH Recommended Exposure Limit (REL) – Provides extra safety to employee – Based on scientific data – Not legally enforced Sentry Air Systems • www.sentryair.com
- 12. Government Standards Data from Occupational Safety and Health Administration. “OSHA Annotated Table Z-1.” https://www.osha.gov/dsg/annotated-pels/tablez-1.html. Substance OSHA PEL NIOSH REL Aluminum (respirable) 5 mg/m3 5 mg/m3 Beryllium 0.2 µg/m3 (0.0002 mg/m3) 0.2 µg/m3 (0.0002 mg/m3) Boron trifluoride 1 ppm 1 ppm Copper (fume) 0.1 mg/m3 0.1 mg/m3 Hydrogen fluoride 3 ppm 3 ppm Iron oxide (fume) 10 mg/m3 5 mg/m3 Lead 0.05 mg/m3 0.05 mg/m3 Rosin core solder (formaldehyde) 0.1 mg/m3 0.1 mg/m3 Silver 0.01 mg/m3 0.01 mg/m3 Zinc oxide 5 mg/m3 5 mg/m3
