Television is suitable for dim atmosphere. You usually close the curtains. Then cover the curtains when singing. For fire safety, it is necessary to hang a fire extinguisher. This is a place that can only be opened after the acceptance of the fire department. So every ktv should have fire emergency equipment.
It is suggested that the fire extinguisher should be placed on the edge of the aisle, even in the KTV box, because the light in the box is too dim to see clearly.
