2Most common Demolition Citations No Engineering SurveyNo hazard or utilities identificationNo exterior chutesNo canopy for entrances
3Types of Structures Covered by the Standard Chimney, Stack, Silo, or Cooling TowerPre-stressed Concrete StructuresPre-cast Units Stressed Separately from the Main FramesMonolithic StructuresProgressively Pre-stressed StructuresConfined Spaces
4Demolition Preparation Engineering SurveyUtilities LocationMedical ServicesPolice and Fire Contact
5The Engineering Survey Survey is required by OSHA (a)Survey determines the condition of framing, floors, and walls to prevent premature collapse of any portion of the structure.Helps the contractor plan the jobMethods of Wrecking (equipment needed)Man PowerProtection of the Public
6Utilities Location Alabama One Call 1-800-292-8525 or 811 Must call at least 48 hours in advanceService is available Monday through Friday, 7:00 am to 5:00 pmAll utilities are marked in a standardized color code
7Medical Services and First Aid Provisions should be made for prompt medical attentionMake sure first aid kits are properly stocked and accessibleEmergency phone numbers should be readily accessible
8Shoring and BracingBrace or shore walls and floor structures that have been damaged and may require employee entry.No work is permitted where structural collapse hazards exist until they are corrected by shoring, bracing, or other effective means.Demolition of exterior walls and floors must begin at the top of the structure and proceed downward.Structural or load-supporting members on any floor must not be cut or removed until all stories above that floor have been removed.
9Fire Prevention and Protection A fire plan should be established prior to demolition.Fully charged portable fire extinguishers should be provided throughout the operation.Electrical wiring and equipment for providing light, heat, or power should be installed by a competent person and inspected regularly.Local fire departments are often willing to assist in pre-demolition structure assessments.
10Ordinary Combustibles ExtinguishersOrdinary CombustiblesIncludes materials such as wood and paperFlammable LiquidsIncludes fuels, grease, other liquidsElectrical FiresContains non-conductive smothering agent
11How to Use a Fire Extinguisher P-A-S-SPull -- Pull the pin at the top of the extinguisher that keeps the handle from being activatedAim -- Aim the nozzle at the base of the fireSqueeze -- Maintain a distance of eight to ten feet away from the fire and squeeze the handle. Discharge will only occur if the handle is being squeezed.Sweep -- Sweep the nozzle back and forth at the base of the fire until it appears to be out.
12Demolition ChecklistMake sure workers are using the right PPE for the job (noise & dust exposures)Dispose of all materials properlyInsure that workers are not exposed to energized power sourcesEducate workers on the special hazards they may encounter (lead paint)Educate workers on the application and use of fall protection
