So the O2 level in the room begins to decrease.So in a few hours there will be incomplete combustion in the BBQ hearth. As a result of that it emits CO gas that can cause deaths.

Answer for the Question of the Week

Small birds are not so large to make a contact with both the positive & neutral lines.So they suffer no electric shocks because they do not get earthed. Once they are not earthed, electricity can’t pass through their body,hence they do not get a shock. However bats hang down between both wires and there is a possibility to contact with both positive & neutral lines & they get the shocks that can killed themselves.
