.3 Cooperate with respective trades to determine methods and procedures to ensurewatertight junctions to items passing through roof.

.4 Do not use direct fired equipment. Use only kettles equipped with thermometers orgauges in good working order.

.5 Locate kettles in a safe place outside of building. When locating kettles, giveconsideration to direction of prevailing winds, building fans and air handling units tominimize possibility of smoke and fumes entering surrounding occupied buildings. Ifwind direction causes smoke and fume problems, relocate kettles on a daily basis asdirected by the Engineer.

.6 Maintain supervision while kettles are in operation and maintain metal covers forkettles to smother flames in case of fire. Supply suitable fire extinguishers.
