5 Introduction to the Israel Standard This Israel Standard is the American Standard ANSI/NFPA 130 from the year 2000, approved as an Israel Standard with Israel national deviations. The following are brought in the Hebrew language: - The Scope clause with Israel national deviations - Details of the Israel national deviations to the clauses of the American Standard Israel national deviations were added only in places where it was necessary to modify the requirements of the American Standard to the legal requirements, regulations, Israel Standards and the organizational system in Israel. After the Hebrew part, the American Standard is brought in the English language only. Scope (Clause 1-1 of the American Standard with Israel national deviations) This Standard covers fire safety requirements for fixed guideway transit and passenger rail systems. These are underground, surface, and elevated systems of light transit, "metro trains" and heavy passenger vehicles. The Standard is applicable to the rail guideways, the vehicles themselves vehicles and cars, stations, maintenance and storage areas and their facilities, smoke control systems, emergency communication and emergency procedures. The Standard relates to the fire safety of passengers and the employees in the stations, on the rail guideways and on the vehicles themselves. This Standard establishes minimum requirements for each of the identified subsystems. In the case of difficulty in maintaining a specific requirement given in this Standard, due to topographic or other reasons related to the physical design of the rail system, the Firefighting and Rescue Commissioner has the authority to lighten the requirement according to the specific reason and the principles of the Standard. In addition to this Standard, other Israel Standards are applicable to the safety of the rail system, such as SI 1227 Part 2, SI 5350, SI and SI Parts 1 and This Standard shall not cover requirements for the following: 1. Conventional freight systems; 2. Buses and trolley coaches; 3. Circus trains; 4. Tourist, scenic or historic operations; 5. Any other system of transportation not included in the definition of To the extent where a system, including those listed above in subclauses 1 to 5 introduces hazards of a similar nature to those addressed herein, this Standard, shall be permitted to be used as a guide. 1

6 1-1.3 Nothing in this Standard is intended to prevent the use of new methods, materials or devices, provided that sufficient technical data are submitted to the authority having jurisdiction to demonstrate that the new methods, materials and devices are equivalent to or superior to the requirements of this Standard with respect to fire resistance and safety. This use of new methods, materials or devices is conditional on meeting the requirements of Israeli laws or Israel Standards, and lacking an Israel Standard, the requirements of an International Standard, regional Standard or national standard, and approval of the authority having jurisdiction.

It shall be at least 4 m wide. The height without obstacles shall be at least 4.70 m for the complete length and width of travel path. The height can be lowered to 4.20 m under structures (such as bridges) and near the entrance and exit from them. Access points shall be provided for a fire and rescue vehicle from the regional road system to this lane, at distances not greater than 3 km. for the length of the route. Where the distance between two stations does not exceed 3 km, one access point is sufficient and it shall be widened to allow maneuvering and return of the fire vehicle at each end of the access lane. Where the rail strip is fenced in and the access lane along the route is between the fenced region, the access to the lane shall be through a gate or a free opening in the fence, at least 4.5 m wide and at least 4.2 m free height. Alternatively, or in sections along the route, where there is no such lane, access shall be provided for firemen to the rail route, such that the maximum walking distance from the access opening for the entrance of firemen to the farthest point in the rail route, accessible through this opening, does not exceed 190 m. The net width of the opening, including the gate, if installed, shall not be less than 1.6 m. Such an access gate shall be located so that the fire and rescue vehicle can approach it from the regular road system. Alternatively, the accessibility of fire and rescue forces shall be possible by specific equipment in accordance with the requirements of the Fire authority, that can travel on the rail. This equipment shall be supplied by the rail operator. Alternatively, the accessibility of fire and rescue forces shall be possible in a manner that an emergency vehicle can travel on the track bed, and enables it to maneuver at each end of the access lane. 21

The following shall be added to the clause: If there are bridges or embankments higher than 30 m above the access roadway: 1. Access shall be possible in a manner that an emergency vehicle can travel on the track bed. 2. Along the track, a 3" diameter fire tap in accordance with all parts of Israel Standard SI 448 shall be installed every 90 m. The water feed line shall be at least 4" in diameter. The line water pressure shall not be less than 2 bars and not greater than 7 bars. The minimum water flow to a single 3" fire tap shall be 400 l/min. 3.
