SUMMARY

The discussion focuses on the hazards associated with welding on materials treated with chlorinated solvents, particularly in the context of industrial construction projects. Participants highlight the need for a list of commercially available products containing chlorinated solvents used in metalworking, as existing resources primarily list chemical compounds. Notable products mentioned include CRC Brakleen and CRC Heavy Duty Degreaser, both of which contain tri and tetrachloroethylene. The conversation emphasizes the importance of awareness regarding these chemicals to ensure safety during welding operations.

PREREQUISITES
  • Understanding of OSHA regulations related to chemical safety
  • Familiarity with welding processes and safety protocols
  • Knowledge of chlorinated solvents and their applications in metalworking
  • Awareness of industrial degreasing products and their chemical compositions
NEXT STEPS
  • Research the safety data sheets (SDS) for CRC Brakleen and CRC Heavy Duty Degreaser
  • Investigate the effects of chlorinated solvents on welding processes
  • Learn about alternative degreasing agents that do not contain chlorinated solvents
  • Explore OSHA guidelines for handling hazardous materials in industrial settings
USEFUL FOR

This discussion is beneficial for industrial construction project managers, safety officers, welding supervisors, and anyone involved in metalworking who needs to understand the implications of using chlorinated solvents in their operations.

I am taking the OSHA 30 course as a requirement of a job and came across some information regarding the danger of welding on materials that have had chlorinated solvents applied. Being someone who manages industrial construction projects, but often doesn't supervise welding operations, I am not familiar with a chemical product commonly in use for metal working applications that would have chlorine in it.

Is there a list available of common products that contain chlorinated solvents? So far, I am only seeing lists of chemical compounds, not off the shelf brand names that would be used for welding applications.

(Yes, I know bleach contains chlorine, I am looking for something that is likely to be used in metal working applications).
 
Physics news on Phys.org
Degreasing solvents containing methylene chloride or chloroform or carbon tetrachloride or the various chlorinated versions of ethylene are what is being discussed.

CRC Brakleen contains tri and tetrachloroethylene. It is also sold as CRC Heavy Duty Degreaser.
