Alarm Systems: Pull Stations

Fire alarm manual pull stations are installed to manually activate a building's alarms in addition to the automatic fire sensing devices. When pulled manually, a pull station activates the fire alarm system and notifies University personnel that an emergency exists. Pull stations are located near exit stairways and/or building exits.

If you smell smoke or if you see smoke or a fire, complete these steps:

  1. Pull a manual pull station to evacuate the area.
  2. If you are not in immediate danger, call 9-911.
  3. If you are trained in fire fighting and it is reasonably safe to do so, attempt to extinguish the fire.

14. Reporting of Fires

  1. All fires that result in death, injury, or significant property damage must be reported immediately to the Director of Administration.
  2. The Director of Administration will notify the State Fire Marshal (512/305-7900) of the incident.
  3. The State Fire Marshal's Office will determine if an investigation is warranted.
  4. No clean-up of the fire damage should occur until the State Fire Marshal's Office has made an investigation decision.
  5. The Director of Administration will notify the component Dean/Director of the State Fire Marshal's decision and provide the appropriate protocol for clean-up of the fire damage.

15. Alarm Systems: Horns and Lights

Emergency horns/bells and lights are located throughout University buildings with fire alarm systems. They are typically found near emergency pull stations. Do not block emergency horns or lights. Report damaged or defective horns and lights to your component's Health & Safety Department or the TAMUS-HSC Director of Administration.

16. Fire Suppression

TAMUS-HSC uses various types of fire suppression equipment including portable fire extinguishers, sprinklers, halon systems, carbon dioxide systems, and fire hose/standpipe systems. The following sections discuss each type of fire suppression equipment.

17. Fire Extinguishers

Fires are classified according to three basic categories. Each type of fire requires special treatment to control and extinguish it. Therefore, all fire extinguishers are clearly marked to indicate the fire classes for which they are designed.

Fires are classified as indicated below. Refer to the table on the following page for additional information.

  • Class A: Fires involving ordinary combustibles such as wood, textiles, paper, rubber, cloth, and trash. The extinguishing agent for a Class A fire must be cool. Water and multi-purpose dry chemical fire extinguishers are ideal for use on these types of fires.
  • Class B: Fires involving flammable or combustible liquids or gases such as solvents, gasoline, paint, lacquer, and oil. The extinguishing agent for a Class B fire must remove oxygen or stop the chemical reaction. Carbon dioxide, multi-purpose dry chemical and halon fire extinguishers are ideal for use on these types of fires.
  • Class C: Fires involving energized electrical equipment or appliances. The extinguishing agent for a Class C fire must be a nonconducting agent. Carbon dioxide, multi-purpose dry chemical, and halon fire extinguishers are ideal for use on these types of fires. Never use a water fire extinguisher on a Class C fire.

There are numerous types of fire extinguishers; however, most extinguishers contain water, carbon dioxide, or dry chemicals. The Halon agent is no longer available for purchase. Halon has been determined to be an ozone-depleting agent. Halon fire extinguishers are safe to use, however, if used, the extinguisher will be replaced by a different type.

18. Inspection,Testing, & Recharging

The Environmental Health & Safety Department inspects and tests fire extinguishers regularly. The Environmental Health & Safety Department also recharges extinguishers. (Fire extinguishers must be recharged after every use.) To move a fire extinguisher to a new location or report a missing or damaged fire extinguisher, call the Environmental Health & Safety Department.
