. It shall be 42 wide and shall swing out into the corridor. Typically a one or two hour rating is required. What is dry type electrical equipment.

Bob December 22 2014 at 313 pm - Reply. Access doors shall be provided for all elevator machine rooms or enclosures and shall conform to the following. The door serving each room shall be a fire rated door in accordance with the applicable provision of the Building Code.

In order to omit them from the space it must be dedicated to electrical equipment only use only dry - type electrical equipment is a 2-hour fire-rated enclosure and no combustible storage is allowed in the room. Traction elevator machine rooms containing elevator equipment only Protected by smoke detectors or other automatic fire detection Area is separated from the remainder of the building by fire rated construction No storage Exception is NOT for hydraulic elevators. IBC Section 30021 requires that hoistways comply with Section 713 for shaft enclosures.

The rating must be equal to the rating of the hoistway. ASME A171 The Safety Code for Elevators and Escalators requires machine room temperature to be as determined by the elevator manufacturer. 2 A room containing elevator machinery need not be.

Since then Precision Fire Protection has flourished into a statewide fire protection construction leader. Precision Fire Protection started in the field 15 years ago. The fire-resistance rating shall not be less than the required rating of the hoistway enclosure served by the machinery.

Therefore if the shaft connects four or more stories then the hoistway and the machine room must have a fire-resistance rating of 2 hours or 1 hour if connecting fewer than four stories. The proper rating for the type of construction should be verified by the local jurisdiction at time of plan review. In a 2-story building with 1-hour rated stair and elevator shafts we know that 60 minute doors are required on stairways from the chart 7154 as they are in a shaft.

Fire Separations for Elevator Machine Rooms. If an elevator hoistway is not required to be rated is the machine room required to be rated. The question is if the elevator machine room for a room that abuts the elevator shaft needs a 45 or 60 minute door.

All mechanical equipment rooms that house elevator machinery shall be lockable and securable such that access is limited to elevator mechanics employed by the U of I. 762mm and a minimum height of 6 ft 183m for machine rooms and a minimum height of 30 in. The need for sprinklers is addressed for three different locations.

Unlike the hoistway no such fire rating is specifically indicated for elevator machine rooms by the OSSC. No Section 30064 requires fire barriers horizontal assemblies or both to separate the machine room from the rest of the building with a fire-resistance rating no less than the rating required for the hoistway. Wires or cables that are located outside of the elevator hoistway machine room control room and control space and that provide normal or standby power control signals communication with the car lighting heating air conditioning ventilation and fire-detecting systems to occupant evacuation elevators shall be protected by construction having a fire-resistance rating of not.

For other than fire service access elevators and occupant evacuation elevators where machine rooms machinery spaces control rooms and control spaces do not abut and do not have openings to the hoistway enclosure they serve the fire barriers constructed in accordance with Section 707 or horizontal assemblies constructed in accordance with Section 711 or both. Typically the entrance door to the elevator equipment room is required to be fire-rated and a fire-rated door with a manual flush bolt may not operate as NFPA 80 requires. The International Building Code requires that elevator machine rooms and machinery spaces have at least the same rating as the elevator shaft.

The heating system for the machine room also is a built. All door openings in a 1-hour barrier are required to be ¾ hour fire rated with fire rated frames. Elevator machine rooms and machinery spaces shall be enclosed with fire barriers constructed in accordance with Section 707 or horizontal assemblies constructed in accordance with Section 712 or both.

1 Except as permitted by Sentence 2 a room containing elevator machinery shall be separated from all other parts of the building by a fire separation having a fire-resistance rating not less than that required for the vertical service space containing the elevator hoistway. Most building elevator mechanics and manufacturers maintain elevator machine rooms between 60F and 80F with 35 to 60 relative humidity. At the bottom of the pit at the top of the hoistway and in the elevator machine room machinery space or control room.

A Have a minimum width of 30 in. Wires or cables that are located outside of the elevator hoistway machine room control room and control space and that provide normal or standby power control signals communication with the car lighting heating air conditioning ventilation and fire-detecting systems to fire service access elevators shall be protected by construction having a fire-resistance rating of not less. The openings into the machine room also need to be protected with doors having a fire rating equal to the fire rating of the doors protecting the hoistway elevator shaft.

762mm for other spaces specified in Sections 3011 e 2 and 3011 e 3. The images below demonstrate hydraulic elevators and traction elevators and show the different locations where the need for sprinklers must be evaluated.
