Hazards of Solder Fume & Fume Extraction Equipment Recommendations

  1. 1. and some ventilation and fume extraction options. Presented by: Sentry Air Systems, Inc.
  2. 2. Weller®, a manufacturer of soldering andwelding products (among other items),explains that "at least 20% of the employeesworking in the soldering area show clinicalsymptoms of asthma caused by the workenvironment" in studies that have been doneon workers mostly in the United States andEngland in the electronics industry. [3]
  3. 3. Soldering is theprocess ofcombining twometals via a thirdmetal (the "joint")with a lowermelting pointthan the basemetals.
  4. 4. Lead-based SolderMany popular solders are manufactured with lead, awell-known metal with dangerous health hazards.According to OSHA:“Lead is used in the soldering process in the form oflead/tin and lead/silver filler metals. When heated, Excessivelead oxide fumes are formed.exposure to lead oxide fumescan result in lead poisoning.Symptoms include loss of appetite, indigestion,nausea, vomiting, constipation, headache,abdominal cramps, nervousness, and insomnia.According to Kirk-Othmer, lead is absorbed throughthe mucous membranes of the lung, stomach, orintestines and then enters the bloodstream.” [1]
  5. 5. Lead-based Solder"Symptoms include metallic taste in the mouth, lossof appetite, nausea, abdominal cramps, andinsomnia. In time, anemia and general weakness, Leadchiefly in the muscles of the wrists, develop.adversely affects the brain, centralnervous system, circulatory system,reproductive system, kidneys, andmuscles." [5]
  6. 6. Rosin-based FluxFlux is a chemical cleaning agent thatis used in conjunction with solder in order to removeoxidation from the base and filler metals involved insoldering. It improves the overall flow and effectiveness ofthe solder. Rosin-based flux is made from extracts of pinetree sap and can cause health problems if fumes fromsoldering are inhaled. According to the WorkSafe WesternAustralia Commission, “short term problemscan include nose, sinus, eye andthroat irritation and skin rashes, andlong term problems may includeasthma and dermatitis.” [2] OccupationalAsthma is a common result of solder fume exposure.
  7. 7. Rosin-based FluxColophony is the base product offlux. As explained by Weller®, "Colophony is thetranslucent amber-colored rosin obtained whenturpentine is distilled from resin of pine trees." It iscomposed of roughly 90% resin acid and 10% neutralmaterial. When the flux is heated, colophony hasbeen known to generate fumesincluding aliphaticaldehydes (likeformaldehyde) and "hydrochloricacid and other gases containingbenzene, toluene, styrene, phenol,chlorophenol and isopropyl alcohol."
  8. 8. Rosin-based FluxThe health hazards associated with solder fumescreate long-term discomfort and illnessfor employees, and results inincreased employee absence, turn-over and a high number of workerclaims for damages (Weller® cites that "90% ofall claims in the United States related to solderingoccupations involving respiratory diseases are litigated."[3])
  9. 9. Your Rights as an EmployeeThe Occupational Safety and Health Act of 1970 [6]states that "employers are responsible for providingsafe and healthful workplaces for their employees." Itis your right to inform your employer of workplacehealth hazards like poor ventilation during soldering.(The Whistleblower Protection Program protectsemployees who raise health and safety issues to theiremployers [7]).

  10. 10. VentilationBecause of the high risk of worker/operator exposure during soldering, OSHAsuggests Ventilation as a key to controlling lead exposures:“Ventilation, either local or dilution (general), is probably themost important engineering control available to the safety andhealth professional to maintain airborne concentrations oflead at acceptable levels. Local exhaust ventilation, which includes bothportable ventilation systems and shrouded tools supplied with ventilation, isgenerally the preferred method. If a local exhaust system is properly designed, itwill capture and control lead particles at or near the source of generation andtransport these particles to a collection system before they can be dispersed intothe work environment.” [4]Source capture also works effectively for soldering that does not involve lead-basedsolder. Organizations from The Health and Safety Executive of Great Britain tosolder equipment manufacturers, like Weller®, suggest a fume extraction systemwhile soldering. Image Credit: www.ohshub.com
  11. 11. Get Ventilated.
  12. 12. Here are some Options.
  13. 13. Source-Capture Fume Extraction Source-capture fume extraction equipment captures fumes at the source of emission, before they’re able to escape into the general working environment.
  14. 14. Sentry Air Systems Source-Capture Solder FumeExtractors are equipped with energy-efficient fans andhigh-quality HEPA filtration media that is up to99.97% efficient on particles 0.3 microns and larger. Popular Fume Extractor Configurations Include: • Bench-top Units • Wall-Mounted Units • Floor Units
  15. 15. Sentry Air Systems Benchtop Solder Fume Extraction Models The Stainless Steel Solder Sentry is an ESD-Safe solder fume extraction unit. It is constructed for stationary, benchtop applications that require the capture and filtration of airborne contaminants at the work surface. This has been proven to work well for solder fumes and smoke extraction.Model # SS-100-SS-STStainless Steel Solder SentryESD-Safe
  16. 16. Sentry Air Systems Benchtop Solder Fume Extraction Models The Solder Sentry is built specifically for stationary, benchtop soldering applications where airborne solder fumes need to be captured at the work surface.
