Fire Prevention and Safety

Ionization detectors
Ionization detectors contain radioactive material that ionizes the air, making an electrical path. When smoke enters, the smoke molecules attach themselves to the ions. The change in electric current flow triggers the alarm. The radioactive material is called americium. It's a radioactive metallic element produced by bombardment of plutonium with high energy neutrons. The amount is very small and not harmful.

Photo-electric detectors
These type of detectors contain a light source (usually a bulb) and a photocell, which is activated by light. Light from the bulb reflects off the smoke particles and is directed towards the photocell. The photocell then is activated to trigger the alarm.

When choosing a smoke detector, there are several things to consider. Think about which areas of the house you want to protect, where fire would be most dangerous, and how many you will need.  

The safest bet is to have both kinds or a combination detector with a battery back up. Be sure to check for a testing laboratory label on the detector. It means that samples of that particular model have been tested under operating conditions. Check to see if it is easy to maintain and clean. Be sure bulbs and batteries are easy to purchase and convenient to install.

Placement
The placement of smoke detectors is very important. Smoke detectors should be placed:

• Inside each sleeping area
• In each hallway (2 if longer than 30 feet)
• On every level of the home, in or near living areas, including the basement
• At the top of each stairwell
• Smoke detectors are NOT recommended for kitchens

Mounting
You can mount many detectors by yourself, but those connected to your household wiring should have their own separate circuit and be installed by a professional electrician. If you mount your detector on the ceiling, be sure to keep it at least 18 inches away from dead air space near walls and corners. If you mount it on the wall, place it six to 12 inches below the ceiling and away from corners. Be sure to keep the detector away from fireplaces and wood stoves to avoid false alarms. Keep them high because smoke rises.  

Keeping smoke detectors in good condition is easy. Always follow the manufacturer's instructions. Be sure to replace the batteries every year or as needed. Most models will make a chirping, popping or beeping sound when the battery is losing its charge. When this sound is heard, install a fresh battery, preferably an alkaline type.

Replace bulbs every three years or as needed. Keep extras handy. Check the smoke detector every 30 days by releasing smoke or pushing the test button. Clean the detector face and grillwork often to remove dust and grease. Never paint a smoke detector as it will hamper its function. Check your detector if you've been away from home.

Inspections cover business areas, public areas and exterior space of businesses and multi-family residential buildings.

Business owners have direct contact with fire inspectors allowing for open dialog on fire related topics.

Yes. The fee ranges from $25 to several hundred dollars depending on business size and inspection difficulty. The fees pay for a portion of the cost of the fire inspection program and staff.

Businesses generally have 14 days to comply with the fire code as noted on the fire inspections. Life threatening or repeat violations may need to be corrected immediately or within a short timeline.

Report corrections to your fire inspector within 14 days of the inspection.

Businesses are liable for problems noted during the fire inspections. A Fire Inspector will contact you in an effort to correct the items that are outstanding. You may be billed for additional time spent on issues due to noncompliance.
