Fire and Life Safety Systems

707 17th St. Fire and Life Safety Systems

A modern high-rise building has hundreds of occupants and represents a complex community. It is now agreed that total evacuation of a building is generally the preferred response to be taken in an alarm.

Evacuation is the appropriate response in buildings such as Denver City Center that meet the criteria of required safety features covered below.

The major hazard to occupants in a fire is smoke. Smoke is responsible for 85% of all fire deaths, which is more than all other causes combined (i.e. burns, falls, explosions, heart attacks, etc.).

The controls for the firefighter that interface with the Fire/Life Safety systems are located in the Fire

Command Center (FCC) on the street level of the building. The Security Desk that is also located on the street level is staffed 24 hours a day. The security personnel at this desk are responsible for the following:

Assisting the Fire Department and building management during emergencies. Monitoring the elevator systems and communications.

Identifying and issuing badges to authorized vendors that enter the building.

Communications dispatching between security and building management. Also with tenants via the Public Address System.

 

Fire Detection Features

Smoke Activate - Smoke detectors are located in electrical closets, switch gear rooms, air handling ducts, all mechanical areas, elevator shafts, common corridors and elevator lobbies.

 

Person Activated - Fire alarm pull stations are located adjacent to each fire stairwell access door.

 

Fire/Heat Activated - Each floor of the building has a water flow switch for the fire sprinkler zone on that floor. When a sprinkler head is activated and water begins to flow through the pipe, a flow switch will activate the alarm.

 

Fire Suppression Features

The building construction incorporates fire-rated doors and walls to maintain critical separation to slow the spread of smoke and fire.

 

A steel cabinet is located by each of the two fire stairwells. Each cabinet contains a Fire Department hose connection to the wet standpipes that run the entire height of the building.

 

An ABC type fire extinguisher is located in the same steel cabinet located by each fire stairwell.

A fire pump supplies water to the fire sprinklers in all sprinkler areas and hose valves throughout the building.

 

Upon activation, affected sprinkler heads will release water to extinguish a fire.

 

Emergency power is provided by a diesel-driven emergency generator that supplies power to the fire alarm systems and equipment, fire pumps, smoke control fans and dampers, emergency lighting and limited elevator service.

 

 

Life Safety Features

  • Visual alarms (strobes) are located in all common areas of the building - lobbies, common corridors, restrooms and tenant areas.

  • The public address system provides communications throughout the building via speakers located in elevator lobbies, common corridors, stairwells, mechanical rooms and other tenant locations.

  • Fireman’s Communication System phone jacks are located throughout the building in elevators, elevator lobbies, adjacent to the fire alarm pull stations outside of every fire stairwell, and in freight elevator vestibules to provide firefighters with two-way communication with the Fire Command Center.

  • Rescue assistance intercoms are located on every 5th floor in the emergency stairwells.

  • Each elevator is equipped with an intercom system, as well as a speaker connected to the public address system.

  • Denver City Center is equipped with a smoke control system that provides floor and stairwell pressurization and smoke exhaust automatically in the event of an alarm. These systems are designed to exhaust smoke from the fire floor while pressurizing other areas to prevent smoke infiltration.

  • Upon alarm activation, all elevators are automatically called to the street level, or to an alternate floor in the event of an alarm on the street level.

  • Upon alarm activation, all electro-magnetic locks in the building automatically unlock allowing unrestricted egress.

  • Denver City Center is constructed with two fire stairwells, constructed of concrete and steel that provide a protected means of exiting the building in an emergency. These stairwells are equipped with emergency lighting connected to the emergency generator.

Life Safety System Testing: on a daily basis the stairwell pressurization and smoke exhaust fan controls are inspected for automatic control and logged on the startup forms. On a weekly basis the fans are tested and operated from the lobby FCC and logged on the weekly life safety fan test form. Preventative maintenance is conducted on a bi-monthly, quarterly, semi-annual, and annually.

 

  • Fire Alarm System: The fire alarm system is designed to provide both monitoring and activation sequencing upon the activation of smoke and heat detectors and water flow switches.

 

  • Fire Alarm System Test and Inspections: The fire alarm panel is checked daily by Engineering and logged and three times per day by security. The checks conducted are for any points that are active, disabled, or in trouble condition and status condition of the fire alarm panel and fan control panel. A flow and tamper test is conducted quarterly by Engineering. A certified contractor on an annual basis conducts a building wide test of the main fire alarm panel, remote panels, and all reporting and activating devices.

 

Fire Prevention

Do not accumulate quantities of discarded files or other paper trash in your office or storage area. Pay special attention to housekeeping in those departments that produce quantities of debris, such as duplication machines, mailing and receiving rooms.

 

Do not store large quantities of flammable solvents, duplicating fluids, or other combustible fluids.

 

Keep electrical appliances in good repair. Report unsafe conditions to the building office.

 

When furnishing an office, consider the fire potential of materials used in large amounts, like overstuffed chairs, settees, couches or anything that could become a combustible item. Such furnishings should be flame proofed.

 

Where potential for fire is especially high, such as supply rooms, tenants may wish to consider installing additional fire extinguishers.

 

Fire Emergency

IF YOU DISCOVER A FIRE, you should remain calm and:

 

  1. Pull the nearest fire alarm. Alarms are located in the corridors adjacent to the stairwells.
  2. Call 911 from a safe location.
  3. Evacuate or relocate and assist all others in the immediate area.
  4. Close doors behind you to isolate fire.
  5. Proceed to stairwells and listen for instructions. NEVER use the elevators.
  6. Be cautious when opening doors so as not to spread the fire. Touch any door to see if it is hot before opening.

 

If smoke is present, stay low and crawl with your body against the floor. The clearest air is near the floor. If forced to make a dash through smoke or flame, hold your breath and cover your nose and mouth with an article of clothing.
