Most common Demolition Citations No Engineering Survey No hazard or utilities identification No exterior chutes No canopy for entrances
Types of Structures Covered by the Standard Chimney, Stack, Silo, or Cooling Tower Pre-stressed Concrete Structures Pre-cast Units Stressed Separately from the Main Frames Monolithic Structures Progressively Pre-stressed Structures Confined Spaces Confined Spaces
Demolition Preparation Engineering Survey Utilities Location Medical Services Police and Fire Contact
The 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 job Methods of Wrecking (equipment needed) Methods of Wrecking (equipment needed) Man Power Man Power Protection of the Public Protection of the Public
Utilities Location Alabama One Call or 811 Must call at least 48 hours in advance Service is available Monday through Friday, 7:00 am to 5:00 pm All utilities are marked in a standardized color code
Medical Services and First Aid Provisions should be made for prompt medical attention Make sure first aid kits are properly stocked and accessible Emergency phone numbers should be readily accessible
Shoring and Bracing Brace 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.
Fire 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.
Extinguishers Ordinary Combustibles Includes materials such as wood and paper Flammable Liquids Includes fuels, grease, other liquids Electrical Fires Contains non-conductive smothering agent
How to Use a Fire Extinguisher P-A-S-S Pull -- Pull the pin at the top of the extinguisher that keeps the handle from being activated Aim -- Aim the nozzle at the base of the fire Squeeze -- 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.
