3. All chemical used for anti-termite treatment are poisonous and hazardous to health. Keep the containers closed and secured. Wear protective clothing while handling the chemicals. Avoid flames in the vicinity during mixing. Never allow treatment chemicals to contaminate sources of drinking water. Follow instructions provided by the manufacturer in the MSDS ( Material Safety Data Sheet ). In case of poisoning take remedial measures according to the MSDS provided by the manufacturer and as per IS 4015. 2. Health Hazards and Safety Measures Anti-Termite Treatment Scope How to Carry out of Pre-Constructional Anti-Termite Chemical Treatment for the Building.

5. 4. Submit Material Specification and MSDS to EIC before start of work 3. Follow Indian Standard Safety Code and Site Specific Safety rules 2. Anti-termite treatment should be carried out in the early stages of construction of buildings:- Start from substructure and up to plinth level. 1. Anti-termite treatment is a specialist job: Use only specialized agencies for carrying out anti-termite treatment preferably a member of Indian Pest Control Association. 4. General Requirements Anti-Termite Treatment

6. Remove all organic matter, construction debris, rubbish etc. Water logged foundations shall be treated after drying when the soil is absorbent. For low penetration and slopping sites, surface to be scarified 75mm depth. Complete all cutting, excavation, leveling & grading before starting treatment . 5. Site Preparation Anti-Termite Treatment

7. Chloropyriphos 20% EC bearing ISI certification . Dilute 1 part of Chloropyriphos 20% EC with 19 part of water to get 1% emulsion. Indian pest control association approved chemical shall be used. Contractor shall submit purchase vouchers to EIC for verification. 6. Materials Anti-Termite Treatment

8. Chemical emulsion should be applied uniformly by sprayers. Specified rates should be applied at each stages of treatment. Pressure pumps and sprayers of adequate capacity shall be used for proper penetration of chemical. 7. Mode of Application and Rate of Application Anti-Termite Treatment

9. Foundations shall be completely enveloped with chemical barrier. Treatment shall be from sub structure to plinth surface Apply emulsion @ 5 Ltrs/ Sqm for normal load bearing structures Vertical surfaces @ 7.50 Ltrs/Sqm. Legend A - Bottom and sides of trench B - Backfill in immediate contact with foundation wall C - Junction of wall and floor D- External perimeter of building 8. Treatment for Masonry Foundations & Basement Anti-Termite Treatment 7.50 Ltrs/Sqm 5 Ltrs/Sqm Min 300 MM

10. Treatment in Foundation Trenches: In case of normal wall load bearing structures, columns pits, wall trenches and basement, the treatment shall be at 5 litres/ sqm . or surface area of the bottom and sides to a height of at least 300mm. After the foundation work, the sides shall be treated at 7.5 litres/ sqm . of vertical surface of substructure on each side. After the earth filling is done, treatment shall be done by rodding the earth at 150mm centres close to wall surface and spraying the chemical with the above dose i.e. 7.5 litres/ sqm . In case of framed structure, the treatment shall start at a depth of 500mm below ground level. From this depth the backfill around the columns, beams and R.C.C. basement walls shall be treated at 7.5 litres / sqm . of the vertical and at 5 litres / sqm . for the horizontal surface at the bottom in the trenches / pits.

11. 9. Treatment for RCC Foundations & Basement Treatment shall start at a depth of 500 mm below the ground level/FML. Apply emulsion for vertical surfaces @ 7.50 Ltrs/Sqm. Legend A - Min 500 mm below ground level/FML B - Plinth Filling D- FML to Grade Beam top E - FFL to Plinth beam top NGL - Natural Ground Level FML - Formation Level 500 mm below NGL/FML 7.50 Ltrs/Sqm Anti-Termite Treatment

12. 11. Junction of the Wall and Floors Anti-Termite Treatment Continuity of vertical chemical barrier on inner wall surface from ground level to finished floor level is required. Treatment shall be carried out by Placing a channel of 30x30 mm at all junctions of wall and columns with floor before sub grade is laid. Make holes using 12 mm dia rod@ 150mm c/c and breakup the earth up to ground level. Pour chemical emulsion into the holes @ 7.5 Lit/ Sqm . Tamp back the soil into the channel and consolidate the earth.

13. Care to ensure that the chemical barrier is complete and continuous. The treatment shall not be carried out when it is raining or when the soil is wet. Treated soil surface shall not be disturbed. Take immediate steps to restore the continuity and completeness of the barrier system if treated soil gets disturbed. 18. Precautions During and After Treatment Anti-Termite Treatment SPRAYING EQUIPMENT A pressure pump shall be used to carry out spraying operations to facilitate proper penetration of chemical into the earth. The chemicals, concentration and dosage for horizontal and vertical surfaces are based on the IS code of practice for Anti-termite measures in Buildings. IS 6313 (Part-II). PRECAUTIONS DURING MONSOON No spraying shall be carried out when it rains. Treatment should be repeated in plinth areas if it rains immediately after a spraying operation and before the emulsion has soaked into the soil.

14. Measurement shall be made in Sq.mtr on the basis of plinth area of the building. 20. Mode of Measurement Anti-Termite Treatment Rate includes the cost of materials, labour and all tools, plants, sprayers and safety equipments required for complete operation.
