General Types of Building Construction Hazards Light Frame Heavy Wall Construction Heavy Floor Construction Precast Construction
Light Frame Hazards Weakened wall and connections Broken utilities Combustible materials Cracked or leaning walls Separation from foundations Cracked or leaning chimneys or veneer walls Separated porch or upper story connections Loose roof tiles or roof equipment Broken glass and damaged door frames
BRICK PATTERN THAT IDENTIFIES UNREINFORCED MASONRY. HAS BOND (HEADER) ROW AT ABOUT EVERY SIX ROWS. AT FRONTS OF BUILDINGS, THE PATTERN MAY BE HIDDEN BY FANCY MASONRY VENEER
Heavy Wall Hazards Weakened perimeter load bearing walls and connection to floor and roofs Broken utilities Broken parapets, chimneys, ornamental masonry Broken walls and columns Broken structural connections Cracked wall corners, windows, door frames Unsupported collapsed floors Loose HVAC or roof equipment
Heavy Floor Hazards Weakened columns and poor connections between floors and columns Broken utilities “Empty cage” – concrete column failure Broken structural connections Diagonal shear cracking in support beams Broken infill or shear walls Loose HVAC or roof equipment
Precast Construction Hazards Weakened interconnection of structural components – floors, wall panels and beams Broken utilities Broken walls, cracked corbels at beam-to-column connections Cracked columns at top and bottom joints Broken wall panels Loose HVAC or roof equipment
Collapse Patterns Lean-To V-Shape Pancake Cantilever
Collapse Patterns Lean-to collapse V-shape collapse Pancake collapse Cantilever collapse
Personal Protective Equipment Helmets or hard hats, gloves, safety boots Eye protection-goggles or glasses Hearing protection Respiratory protection Dust masks, APRs, B/As Flashlights or head lamps Flash protection-brush gear, coveralls Knee pads Communications gear Personal alarm device
Safety Considerations Lookouts, communications, escape routes, safe zones Safety Officer duties – 1 per incident Watch for hazards Scene safety No active participation with rescue – hands on Utilize a safety check list Use buddy system – teams of 2 that stay together
Communications Communications plan – part of IAP Portable radio and PAD for each rescuer Maintain continuous voice or radio contact Constant progress reports to leader Coordinate with other rescue teams Prearrange emergency evacuation signal Communications with entrapped rescuers
Escape Routes Pre-established paths to safe zones Considerations Direct path may not be the best option Remain in place may be good option Constant updating of egress pathways
Safe Zones Pre-established area of safe refuse from hazards Can be in or out of “hot zone” area Personnel accountability procedure must be used Immediate relay of information must be relayed to operations
Personnel Accountability System Keeps track of all members at all times Assign officer to keep track Conduct checks after any emergency evacuations, periodically throughout incident and when leaving work area
Other Considerations Rescuer hydration Team Rotations Personal hygiene 8 to 12 oz water every 30 minutes during heavy work Team Rotations Rotate on regular basis Consider 15 to 30 minutes for heavy work Personal hygiene Wash hands and face prior to eating, leaving work area Eat or drink only properly prepared and stored foods Stress factors Prolonged rescue operations Fatigue and psychological
