Preventing fire and security systems: In a community of old wooden shop-houses like this, the danger of
fire is very serious – especially since there is so much cooking going on here. So under each of the four
lanes, they have laid big special high-pressure water pipes with outlets along the way in case of fire. The
water comes from the adjacent river. They test the system twice a month, just to check. Security: The
community also hires local people to be security guards, six people on each shift, around the clock, to go
around and make sure everything is OK, check for possible fire hazards.
