DR. MARCELO HIRSCHLER

Dr. Marcelo Hirschler

Marcelo Hirschler has many years of experience with fire safety issues. He provides technical assistance with codes and standards issues (emphasis on fire), as well as consulting services for fire related legal cases. He has published almost 500 papers and six books. He has a strong background in fire performance of plastics (such as PVC or foam plastics) and the effects of flame retardants. He is very active on proposals for development and amendment of codes (leading to regulation), including the building codes (IBC and NFPA 5000), the life safety code (NFPA 101), the national electrical code (NEC, NFPA 70), the mechanical codes (IMC, UMC), the fire codes (IFC, NFPA 1), the residential code (IRC) and the wildland code (IWUIC). He is also very active in development of standard fire tests, practices, specifications and guides (nationally and internationally) within ASTM, NFPA, CSA, ISO and IEEE. He has been appointed to a number of positions of responsibility within codes and standards committees and has received several awards. He was appointed by ICC to the IBC Fire Safety committee for 3 code development cycles.
