Creosote : is a sticky, powdery, shiny, brittle and hard-glazed substance, dark brown or black with an unpleasant odor, resulting from the condensed wood gases and liquids of unburned fuel.
It forms highly combustible deposits that coat the inside walls of chimneys and woodstoves. The more it accumulates, the greater its potential fuel will be when it ignites.
Creosote build-up is a time bomb waiting to happen, and can add significant fuel to a fire situation. And as you see above, this is what can happen if too much buildup occurs...and if you don't happen to keep a helpful fire fighter standing by on your roof..please read tips below on how to keep your chimney and wood stove/heater safe :
Is Your Wood Stove Safe?
Research into safe wood heating installation led to an official code specifying how wood heat appliances should be installed. Most new stoves meet recognized standards and come with installation instructions. Many wood heat appliance retailers, installers and inspectors attend training programs and can give you up-to-date advice on safe installation if you’re upgrading your system.
If you already have a wood heat appliance, have it inspected to ensure it meets today’s safety guidelines – WETT certification. A fire department, building inspector, wood heat retailer or chimney sweep may be able to help with this. Remember, the fire department wants to prevent fires by reducing fire risk. They may do the inspection themselves, or recommend a complete inspection by a certified installer or chimney sweep.
If you're installing a new chimney or wood heating appliance or replacing one wood stove with another, you'll probably need a building permit, and the building inspector may automatically inspect your installation.
- If you ever have a fire either in the stovepipe or in the chimney, have the system inspected by a professional before you use it again. Serious damage may have been done to the pipes or chimney.
- Make sure your home is equipped with working smoke alarms. Add an extra alarm near the exit to the room where your wood heat appliance is located. It can give early warning of smoke from chimney blockage or from something smoldering close to your appliance.
- Keep a fire extinguisher within easy reach of your wood heat appliance – but not too close! Use an all-purpose and approved (ABC) fire extinguisher. Fire departments recommend a 4 or 5 lb 2A-10BC system. Check it every month for any loss in pressure or noticeable damage and follow the manufacturer's maintenance instructions. Read the label carefully before using it.
- A flue gas thermometer can tell you if the temperature of your appliance's flue is within the safe range specified by the manufacturer. Ask a certified professional to explain how these work.
- Keep heat-proof gloves near your appliance. If a log rolls out of the firebox, the fastest way to get it off the floor and back inside is to pick it up – as long as you've got the gloves on!
- Child guards are designed to keep small children away from hot stoves. A certified professional can give you suggestions. Make sure it is made from non-combustible material.
- Check the chimney and flue pipe often for creosote. Clean them regularly – or have them cleaned by a certified professional annually.
- Use properly seasoned wood and follow proper burning techniques to minimize creosote production.
- Check flue pipes for corrosion at least once a year – the end of the heating season is a good time. Replace any pipes beginning to corrode. Don't wait until there are holes – it may be too late!
- Use a covered metal bucket for ashes. Store it carefully outside or on a concrete floor well away from walls or anything that could burn.
Check the door latches, hinges and gaskets of your appliance regularly to be sure they are tight. From: http://www.ibc.ca
As a back up plan.... you should also have a fire alarm. To find out more about this, check our local Kaslo & Area Volunteer Fire Dept website.
