3. 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

4. Demolition Preparation
Engineering Survey
Utilities Location
Medical Services
Police and Fire Contact

5. 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)
Man Power
Protection of the Public

6. Utilities Location Alabama One Call 1-800-292-8525 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

7. 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

8. 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.

9. 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.

10. Ordinary Combustibles
Extinguishers
Ordinary Combustibles
Includes materials such as wood and paper
Flammable Liquids
Includes fuels, grease, other liquids
Electrical Fires
Contains non-conductive smothering agent

11. 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.

12. Demolition Checklist
Make sure workers are using the right PPE for the job (noise & dust exposures)
Dispose of all materials properly
Insure that workers are not exposed to energized power sources
Educate workers on the special hazards they may encounter (lead paint)
Educate workers on the application and use of fall protection
