Question 1

Can you use flour to put out an electrical fire?

Accepted Answer

•

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable.

Question 2

What if my smoke detector is too high to reach?

Accepted Answer

•

Your smoke detector might be too high in some homes or circumstances to reach yourself. If you feel unsafe getting on a ladder to replace your hardwired smoke detector, call a licensed electrician or local handyman to knock this project off your to-do list. If you have a battery-operated smoke detector, your local fire department can change the batteries or help you replace the detector—just make sure you call the non-emergency number.

In any case, do not let this project go unresolved, as it could turn into a huge safety issue.

Question 3

Can a bad light switch cause a fire if the light switch is off?

Accepted Answer

•

If a light switch is off, it’s very unlikely to cause a fire. For a fire to start, the switch has to be on, activating an electrical current, and the wiring must be faulty. However, the malfunctioning light switch could cause an intermittent current to move across the electrical wire. This issue could become a fire hazard with another device connected to the wire. You should replace the bad light switch as soon as you notice it or call an electrician.

Question 4

Can you close off a fireplace?

Accepted Answer

•

Yes, you can close off a fireplace both temporarily and permanently with extremely wide price ranges. Temporary solutions involve fireplace plugs that can be inflated to block air and deflated to open the fireplace, covers, and boards. Permanent methods of shutting off fireplaces usually involve bricking up the fireplace or covering it with drywall. No matter the method, it’s probably best to hire a professional.

Question 5

Should an unused chimney be sealed or capped?

Accepted Answer

•

Yes, you should seal and cap an unused chimney to protect it from damage. Sealing the structure helps prevent moisture damage, which can lead to issues like cracks, spalling, efflorescence, and damaged mortar joints. Capping the chimney is also crucial to prevent blockages, damage from invasive critters, and downdrafts, while still allowing for proper air ventilation to manage moisture. For the best results, consult a chimney professional to select the right type of chimney or flue cap for your home. It's also wise to continue with annual chimney inspections to maintain the structure's integrity.
