Study Notes
Incident Safety Officer (ISO) Responsibilities
- The primary responsibility of an ISO is to identify potential hazards and predict building collapse.
- Relying solely on experience to predict building collapse puts firefighters at risk because it can lead to oversight of critical warning signs.
Warning Signs for Structural Collapse
- ISOs need to understand and recognize warning signs such as:
- Cracks in walls or foundations
- Unusual sounds or noises
- Swaying or sagging of buildings
- Visible damage or deterioration
Building Construction Fundamentals
- Buildings must be constructed to resist various forces, including gravity, wind, and seismic forces.
- Loads in building construction refer to the weight of people, furniture, and other objects, as well as external forces like wind and snow.
- Dead load refers to the weight of the building itself.
- Axial load refers to the weight or force applied directly along the length of a column or beam.
Materials and Their Properties
- The fundamental knowledge base of ISOs includes understanding the properties of various building materials, such as:
- Wood: ductile, marginal resistance to forces, can develop surface char when exposed to flame
- Steel: excellent tensile, shear, and compressive strength, loses strength when heated
- Masonry: resistance to forces compared to its weight, can lose bond leading to instability
- Concrete: heat sink, can crack or spall when exposed to heat, reinforcing steel can lose strength
Columns and Beams
- Columns are primary load-bearing elements, providing vertical support to a building.
- Beams are horizontal or sloping elements that span openings and provide support to floors and roofs.
- Types of beams include:
- Cantilever beam: supported at only one end
- Arch beam: spans an opening in a load-bearing masonry wall
Trusses and Connections
- Trusses are triangulated structures that provide support and stability to roofs and ceilings.
- The purpose of connections in structural elements is to transfer loads and provide stability.
- Types of connections include:
- Mechanical connections: use nuts and bolts, screws, nails, or rivets
- Bonded connections: elements bonded together to form a solid union
- Gravity connections: resist gravity loads
Fire Resistance and Safety
- Francis Brannigan emphasized the importance of understanding building construction and materials to predict building collapse and ensure firefighter safety.
- The primary focus of an ISO at the scene of a structure fire is to identify potential hazards and predict building collapse.
- Cooling structural steel with fire streams is crucial to prevent weakening and loss of strength.
