Chimneys should either be sealed or waterproofed, which is different from sealing off—closing at both ends—a chimney.

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches often result from loose wiring, exposed connections, or other electrical problems that can cause overheating or sparking.

If you suspect your light switch is faulty, immediately turn off the power at the circuit breaker and contact a qualified electrician to remedy the issue.

So remember to ensure you have enough installed in your home and that they are working and in good shape.
