- 5. VERTICAL APPROACH Easy access Cleanerwork conditions Body position is more comfortable Easier to use tools and equipments ADVANTAGES
- 6. VERTICAL APPROACH Time consuming Debris/cut piecesmay fall on the victim. Likely to work with concrete. DISADVANTAGES
- 7. Easy penetration Material inmost cases is not concrete. Debris does not fall on the patient. HORIZONTAL APPROACH ADVANTAGES
- 8. Uncomfortable body position Crawling frequentlyrequired Tool position awkward Dirtier working condition HORIZONTAL APPROACH DISADVANTAGES

- 10. Avoid cutting into load-bearingwalls. Shore before removing pieces which are in under pressure. Removing Rubble Remove small pieces first and never remove any pieces that are in under pressure. Verify the condition of building components. Determine pattern of collapsed structure.
- 11. Insp Vijay kumar11 When breaching a wall/floor , always be aware that a trapped victim may be in direct contact with the other side of the wall/floor. Avoid cutting too deeply to prevent damaging structural elements, wires, water pipes etc. Cutting & penetrating Note: Shoring, Lifting and stabilizing loads will discuss in next lessons.
- 12. Secure access area andremove rubble. Establish safety zones and escape routes. Evaluating Access Conditions Mitigate hazards. Proceed to victim marking location. Ensure utilities are cut off.
- 13. Procedures for cutting& penetrating materials Insp Vijay kumar 13
- 14. Procedure for Cuttingand penetrating metal and wood Use full PPE Select the proper tool. Make the work area safe from hazards. Knock on the metal or wood to find a hollow area. Make an inspection hole, use caution when breaking through the other side. 5 4 3 2 1
- 15. Insp Vijay kumar15 Cut a triangular access hole, large enough to permit access. Additionally avoid cutting too deeply.. Remove the piece you have cut, protect against sharp edges. Shore if necessary. 8 7 6

- 17. Procedure for cuttingand penetrating concrete block and brick Now check stability and Shore if necessary. Remove the cut triangle own side and ensure do not push it inside. Mark a triangle (70x70 cm) then firstly start to cut Base of triangle then other arms.

- 25. Horizontal approach Goal is tocut a triangular hole in the concrete. Make the two upper cuts slight angle off perpendicular (80 – 85 degrees). This will prevent the cut portion from falling inward.
- 26. Vertical approach 01 030402 Goal is to cut a square/rectangular hole in the concrete. Make a small hole in the centre of the piece which will be used to lift the cut portion. Cut two opposing sides of the square at a slight angle off perpendicular (70-80 degrees). Complete the square by cutting the remaining two sides in a normal perpendicular fashion.
- 27. Lift out thepiece using the centre hole. Insp Vijay kumar 27 06 05 For reinforced concrete with steel bars or stranded cable, loosen the concrete around the bar and cut the individual bar.
