A bright red warning sign showing the position of the fire extinguisher No 9 with a symbol of flames. Right next to it hangs an ancient petroleum lamp made of green porcelain with a very narrow and long glass cylinder. The metal clamp used to hang it was also for carrying it. These lamps were used in the past to find one's way from the living room to the bedroom. The clamp protected the hand: if one swayed too much and petroleum spilled out, it could quickly cause a fire. Of course, the lamp is empty.
