Operational Safety Considerations at Ordinary and Heavy Timber Constructed Occupancies 

Building Type III and IV Training Materials for the Fire Service

This program was developed to support the case study information published within the 2009 Near-Miss Reporting Calendar for the Month of May, 2009 for the National Firefighter Near-Miss Reporting System.  If you’re not familiar with the NFFNMRS, go to their web site, HERE  for insights on resources and timely operational and training information, data and resources. The National Fire Fighter Near-Miss Reporting System is a voluntary, confidential, non-punitive and secure reporting system with the goal of improving fire fighter safety. 

The Near-Miss Reporting System Report Case Study #08-0099 provided various insights into operational and safety issues affecting incident operations within a complex of warehouses built within the late 1800’s. 

The program objectives consist of;  

  • Increasing awareness of Type III and Type IV construction characteristics.
  • Provide awareness of inherent building construction, stability, performance and collapse considerations.
  • Provide a focus on Type III and Type IV building construction predominant in pre-1960 construction and occupancies.
  • Although Type III and IV construction is utilized in a variety of present day construction projects, these areas are excluded due to production limitations and focus on the near-miss case study reporting correlations.

This program provides an awareness level perspective on selective construction, operational and safety issues affecting the fire service, and does not represent other numerous areas of considerations. Formal training courses within a number of related subject areas is encouraged to increase knowledge and skill sets necessary to further strategic and tactical firefighting operations and incident management.
