Safe practices

Smoke detector installation

The National Fire Protection Association reports 3 out of 5 deaths that occur during fires happen in homes that do not have smoke detectors installed or homes that do not have working smoke detectors. The chances of dying in a fire are reduced by 50 percent when smoke detectors are present. Approximately 74 percent of homes do have working smoke detectors installed.

Generally taught more to adults (particularly homeowners), a core part of fire prevention outreach involves encouraging people to ensure that they have an adequate number of smoke detectors installed in their home and how to maintain them.

  • Smoke detectors are to be tested regularly to make certain that they are in good working order. These steps can significantly reduce deaths in household fires, particularly at night when people are sleeping.
  • Smoke detectors generally make a persistent beeping sound when their batteries run low, and a key part of fire prevention outreach involves encouraging people to replace batteries promptly instead of just removing them to make the beeping stop.

Sprinkler systems

Sprinkler systems are used as a quick water delivery system to prevent a fire from growing beyond the capacity of the fire suppression systems allowing for safe egress. Most sprinkler systems are activated by the breaking of a glass bulb or fusible link by radiant heat of a fire which allows water to flow freely through the open parts of the system. The most common types of sprinkler systems consists of wet-pipe, dry-pipe, & deluge.

A wet-pipe sprinkler system is an automatic sprinkler system in which the supply valves are open and the system is charged with water. They are the quickest at getting water on the fire and are the simplest to maintain. Wet-pipe systems are installed where indoor temperatures can be maintained at or above 40 degrees Fahrenheit (4 °C). If the outside temperature is below freezing and the interior temperature is less than 40 degrees Fahrenheit, the steel sprinkler piping, which rapidly conducts heat and rapidly loses it, will cause the pipes to freeze. The frozen area may be isolated and near an opening or uninsulated portion of the building which could be enough to put the whole system out of service.

A dry-pipe sprinkler system uses a dry-pipe valve that holds water in a certain area leaving the sprinkler pipes empty. These are used in areas where freezing temperatures are common to reduce the risk of damage by water freezing in the pipes. These are activated by a glass bulb or fusible link which when exposed to radiant heat bursts allowing for the air pressure in the sprinkler pipe to drop opening the dry-pipe valve.

Reduction of false alarms

Much of fire prevention education also involves advice on how to reduce false alarms. False alarms have the potential to waste manpower and resources, which may be needed desperately during a real emergency. In addition, firefighters responding to calls in fire engines are at increased risk of traffic collisions when driving under emergency conditions. In 2008 the state of New York found that 18% of firefighter deaths in the line of duty had occurred whilst responding to calls.

Stop, drop and roll

Stop, drop and roll is the most taught part of fire protection education efforts as it is both a simple technique and an effective way of extinguishing burning clothing. It is particularly suited to children who may panic if their clothing catches fire and they do not know how to put it out.
