That’s Not Supposed To Happen
There are certain things in life that we know and trust to perform a specific task. Most of the time these appliances and gadgets work exactly how they should, but then there are times when something strange happens, and they do the opposite of what they are expected to do.
And a fire alarm catching fire would probably not be something anyone would ever expect to happen. Sure, fire alarms aren’t fire-resistant, but they are meant to warn us when the fire is near. But when the fire starts in the alarm itself then you know you are in some trouble.
