Method Statement -Anti-Termite

1.              1 .         OBJECTIVETo outline the sequence of activities, method and resources needed for the operation of

anti-termite soil treatment work.

Soil treatment to protect new buildings against subterranean termites attack should be carried out strictly in accordance with one of the reorganized international codes of anti-termites treatment practice.

2.         SCOPE

The work shall include all labour, material, equipment, safety requirement and services necessary for the execution anti-termite soil treatment work.

Anti-termite treatment is carried out under the Malaysian Standard code of Recommended Practice for soil Treatment of Protection of Building against Subterranean Termites. This code set out a recommended practice for the chemical treatment for the protection of building from attacks by subterranean termites. It includes reference to the chemical used, lay down minimum rates of application for usage and outlines procedures to be followed.

It covers the entire floor area including the aprons with a specially formulated chemical to create an impregnated unbroken barrier.

3.         MATERIAL

           

            Material to be used is as follows:-

               

                3.1          Anti termite chemical – Chlorpyrifos (Termi Force 21.2/Chemicide 75+)

4.         EQUIPMENTS & MACHINERIES REQUIRED

                Equipments and machineries to be used are as follows:-

4.1          Minimum: One (1) no. of power spray pump set (6.3)

                4.2          Minimum: One (1) no. of rubber glove

                4.3          Minimum: One (1) no. of safety glasses

                4.4          Minimum: One (1) no. of mask

4.5          Minimum: One (1) no. of 200 liter water tank

  5.         SITE PREPARATION WORK

5.1          The removal of free stamps, logs or roots from building site reduces the hazard from white ants. Similarly the sub-floor area should be kept free from all debris in which new colonies of termite might be established.

5.2          Anti-termite treatment should be carried out at the stage of the construction when the whole sub-floor area is readily accessible and there is little chance of subsequent soil disturbance, in general, this will be immediately before the slab is poured in case of lean concrete floor.

6.         WORK SEQUENCE AND METHOD

            6.1          Determine the location of the anti-termite treatment to lay (Silage Store).

62           Chemical Usage

               

6.2.1      Formulation – The latest anti-termite Chlorpyrifos with an active ingredient 21.2% which is recommended internationally for Termite Treatment.  It is suggested by Pest Control Association of Malaysia (PCAM) and approved by Pesticide Board of Malaysia.

6.2.2      Chemical Application

·         Rate of application (liters) – 1 liter of Chlorpyrifos : 40 liters of water (1:40)

·         Method of application (liters) – 4.5 to 5 liters of mixed termiticide per square meter.

6.3          Method of Spraying

·         Power spray with high pressure will be used to spray along perimeter of footing and ground beam/wall of the silage store and within built up area with a mixture of 1:40 as recommended by chemical manufacturer.

6.4       The anti-termite treatment shall be started when backfilling and compaction works for ground floor is completed.

6.5          Lean concreting for ground floor slab will start after impregnation the areas with the anti-termite chemical.

7.            QUALITY ISSUES

·      The anti-termite chemical shall be applied in accordance with the manufacturer’s recommendation and label instruction.

·         The minimum surface application rate shall be 5 L/m2 on all ground floors built-up areas including apron areas and also on all areas extending 1.0m beyond the perimeter drain all around the building.

·     The anti-termite chemical shall be sprayed on interfaces between the concrete ground beam and the hardcore at minimum rate of 1 litre per linear meter.

·     Treatment shall not be performed just before or after heavy rain unless the area to be treated can be physically protected as rain may cause leaching and run off before the anti-termite chemical has bound to the soil.

·         Immediately after spraying of chemical, all surface exposed to direct sunlight or rain shall be covered with the building concrete of polythene damp-proof membrane.

·       Upon completion of the entire job, the applicator will issue a warranty valid for TWO-(2) years starting from obtained of CPC. Under this warranty, we will provide quarterly inspections on the treated building. PRIMA PEST CONTROL AND SERVICES will undertake to treat any subterranean termite’s re-infestation without within the warranty period.

·     Any alteration or extension work to the existing building which may result breaching, bridging or bleaching of the treated soil laterally or vertically has to be notified to us for further consultation. Otherwise, the warranty is void and null.

8.         SAFETY ISSUES

·         Safety helmets and safety footwear should always be worn.

·         All soft spots or holes shall be identified and barricade if necessary.

·         Rubber glove, mask and safety glasses should always be worn.

·         The site shall be kept clear of unnecessary obstruction.

·         First aid kit boxes will be provided at site office.

·         During raining, no activities are allowed to work.

·         Unauthorized personnel are not permitted within the construction area.

·         All work will be done by in a safe working environment.

9.         ENVIRONMENTAL ISSUES

·         All workers shall ensure that all tools and equipment machinery are in good condition to avoid any oil leakage that could harm to environment.

·         Water from particular construction area shall be diverted into proper drain which is eventually empties into silt trap.

·         Domestic and construction waste from construction area must be collected into centralized garbage bin and disposed at the designated area.
