Commissioning Method Statement For – Fire Damper Drop Test Document Number: Issue Date: Originated Date: Status:
1. Introduction This Method Statement covers the witnessing of Fire Damper drop test for all fire dampers within all ductwork systems throughout the development. A schedule will accompany this method statement detailing the dampers, the system they are located in and their physical location within the building.
2. Requirements Prior to Test The requirement prior to this test is: a) Safe and clean access to the damper location (access is a requirement of the installation acceptance) b) Lubricate and clean the damper if deemed necessary. c) Relevant Risk Assessments, including the following risks (See Section 15 appendix for attachments): Hand held lamp/torch Hand Tools Ladders and Stepladders Working at heights
3. Design Parameters The location of the fire damper is to be checked against the requirements of the design in respect of the rating and temperature setting of each damper to be tested.
4. Reference Documents/Drawings
Hilson Moran drawing Contractor shop drawing and approval/status Method statement (approved/agreed) Damper test schedule
5. Pre Start Checks/Pre-commissioning a. Each damper is accessible and can be visually inspected to confirm operation. b. Operation of each damper to be confirmed prior to test/witness, and lubrication/adjustment needed to be carried out should be complete as part of this section. c. The size of access required for reset is to be established and agreed during installation.

d. The damper is built, and fire sealed into the wall/floor that the damper is intended to maintain the fire integrity of, in accordance with the requirements of the manufacturer. (Manufacturers details to be provided)
6. Commissioning/Test Procedures a) b) c) d) e) f)
Check installation of Fire dampers as per approved shop drawing. Remove the access door on duct to access damper. Remove the fusible link and verify the damper fully closes properly. Re open the damper and re install fusible link. Lubricate and clean the damper if deemed necessary. Label the testing acceptance on fire damper.
7. Interface Procedure Confirmation that the ductwork system, enclosing the damper is complete, fully pressure tested and insulated.
9. Demonstration and Witness Procedures Dampers are to be offered for witness/demonstrated to the witnessing authority. This is prior to the offer of witness to civil defence. These tests will only be accepted once the regulatory authorities have given acceptance of operational suitability. The witness programme of the fire dampers is to be on a system/floor by floor basis. Details of all statutory demonstrations are also to be included.
10. Commissioning Flow Chart The Contractor is to produce a flow chart based on the commissioning, interface and hand over processes in Sections 6.0 to 9.0. As required by the commissioning authority.

11. Instrumentation
There is no instrumentation required for this test. Tools are required and are listed in 2 above.
12. Staffing Details of the engineer undertaking the process detailed above are required. Staff attending the test and their role and responsibility is required.
13. Safety Aspects & Permit to Work Requirements Health and Safety procedures by the Main Contractor will be implemented for this job. The responsible safety officer as per Main Contractor procedure will conduct a routine safety inspection in conjunction with testing staff.
Safety Rules during testing: In order to ensure safe conditions during testing the following rules have to be followed: Persons engaged with inspection and testing have to be skilled and have received proper and adequate training related to procedures and test equipment utilized for the particular testing activity. Test instruments and test leads should be maintained in a safe condition and the test methods not to create danger either for the operator or for other persons. Where tests are required to circuits which are live for amp readings then the tightness of the cable terminations will be checked without power prior to live amp readings.
Safety Lighting Safety lights will be used in case of power failure ensuring the good illumination of the working area to aid evacuation if necessary.
Task Lighting Adequate lighting shall be provided to ensure the good illumination on the working area.
Emergency Arrangements General:

Site general safety procedures will be followed. In case of emergency the Safety Officer or the most senior employee present will stop the work, and make the necessary emergency arrangements and report to the assembly points as described during Site Induction Course.
Fire Precautions: No significant fire risks associated with this activity but general fire precaution measures will be taken as per Main Contractors instructions. Communication from site areas to Site Office via mobile phones issued to all engineers.
Risk and Controls Hazards / Risks / Relevant risk assessments 3rd Party Protection: Applicable as per the contract only.
Environmental Considerations: All waste materials are to be disposed of in compliance with the clauses in the main contract.
