1.0     SCOPE / OBJECTIVES

This Method Statement covers the installation, testing and commissioning of Fire Alarm System. This procedure is to define the method used to ensure that the Fire Alarm System has been installed as per the contract requirement.

  • REFERENCES
  •   Particular Integrated Fire & Voice Alarm System specification Section 1105/SP/E-16720.
    •    Shop Drawings ref: 1505/A&P/SD/FA
    •    General Specification Clauses 16005, 16010, 16050
  • ACCESS / EGRESS

Work will be carried out only when all associated works of main contractor and A&P being verified that they have been completed.

4.0       HEALTH AND SAFETY HAZARDS.

Health and Safety procedure by Main Contractor and by A&P will be implemented for this job. The responsible safety officer as per A&P procedure will do a routine safety inspection.

  1. 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 will be provided ensuring the good illumination of the working area. The task lighting will get power supply from the nearest power socket (provided by main contractor) which should be protected by relevant RCD.

  • Emergency Arrangements.
  • General: Site general safety procedures will be followed. In case of emergency the safety officer will stop the work, he will administer the emergency arrangements and he will report to 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 Arabtec instructions to A&P.
  • Communication: Communication from site areas to Site Office via mobile phones issued to senior foremen. In emergency situations the users of handheld 2-way radios to be notified if deemed that this can speed up notification of relevant personnel and/or the JBR01 Site Clinic.
  1. Risk and Controls.
  • Relevant Risk Assessments (see Section 19 Attachments):
  • WAH-001 Ladders and Step Ladders
  • MAT-004 Disposal: Waste Materials
  • PRT-007 Hand Tools
  • WAH-002-Mobile Elevated Working Platforms
  • PRT-010 Portable Electronic Equipment
  • 3rd Party Protection: Applicable as per the contract only
  • Environmental Considerations: After the finalization of the works the working area should be cleared of waste materials on a daily basis related to the performed work.
