Separated from unprotected areas by self-closing fire rated doors, normally to a period between half to one hour for occupants to reach a place of safety outside the building, unaided, in the event of a fire emergency.2) Protected Lobby - a lobby surrounded by fire rated building materials and self-closing doors (same as means of escape) for separating means of escape or landings of firemens lift from unprotected areas.3) Any other areas required to be protected to the above standard by local authority.2. Protected areas are required to be kept clear and unobstructed at all times. The Housekeeping Department should be designated to establish a routine to inspect these areas at least once every day for obstructions.3. A standard notice should be devised for the inspecting persons to fill in and transmit to the head of department responsible for the immediate clearance of the obstruction.4. If no action is taken after 24 hours of the first notice, a reminder notice should be sent and copied to the Manager for his action.5. No services, such as air ducts, electric wiring, gas pipes are to be added or pass through protected areas unless such service are boxed in with materials with the same fire rating as the protected areas and to the acceptance of local authority.6. All fire rated doors should be maintained closed at all times, unless they are held open by electromagnetic devices which would automatically release doors to close on the activation of a fire alarm signal from a smoke detector.7. Where doors are located at or within protected areas forming escape routes, locks installed must be able to be opened unaided from the egress side, with simple and legible instruction to open doors.8. Secondary lighting should be installed within protected areas at least two-hour useful illumination duration. For generation fed lights, they should be lighted within 10 seconds after the failure of main power.9. Graphic directional sings and floor numbers should be posted at regular intervals and floor landings along means of escape, preferable with non-radiation type self-illuminating material.Date:08.07.1998Supersedes issue of:15.03.1994Issued by:Billy FongApproved by:Mr Philippe CarettiPage:1/1To:From:Date:Subject:Obstruction To Fire Escape RoutePlease be informed that obstacles belongs to yours department were found on the fire escape route at the following location:-LocationObstaclesPlease remove the obstacle from the aforesaid area immediately.Thank you for your kind attention and co-operation.Billy FongSecurity Manager
