READ EACH SCENARIO, THEN ANSWER EACH QUESTION IN DETAIL A building has been built of steel bar joists, metal roof deck, and masonry walls. A local businessperson is purposing to put a furniture store into the building. What concerns should be noted in the prefire plan related to the steel in this building?

The contents of the building can dramatically affect the structure. It should be noted how the underside of the roof could be reached with hose streams to minimize heat damage to the joists. Special attention should be directed at the building content height as well as the general height of the building. These factors could influence the amount of time it takes for the building to collapse or become heavily involved in a fire that prevents the steel from being cooled by heavy streams.

READ EACH SCENARIO, THEN ANSWER EACH QUESTION IN DETAIL A steel building is under construction when it catches fire on a windy day. What special considerations does this situation pose?

The temporary bracing should be examined closely. It is impossible to make all of the connections as soon as steel is placed. Temporay bolts are placed in rivet holes; thereafter, rivets are driven in the remaining holes, then the bolts are replaced with rivets, or permanent bolts. This practice is known as"field bolting", and it is good to give a wide berth to field-bolted structures during high winds.
