A single 20-foot tall steel I-beam column weighing 1,000 lbs is lifted by a crane and set onto a concrete foundation pier. The ironworkers quickly install two anchor bolts diagonally, tighten the nuts, and signal the crane operator to unhook the sling so they can grab the next column. A stiff gust of wind hits the column. Evaluate the procedure.

An ironworker (connector) is sitting on a column, receiving a 2,000 lb steel beam from the crane. The beam has 4 bolt holes at the connection point. To save time, the connector inserts one bolt, tightening it loosely with a spud wrench, and signals the crane to release the load.

A 50-foot tall structural steel frame is erected. It is not yet tied into the main building core. A wind gust exerts a lateral force of 50 lbs per linear foot on the structure. Calculate the overturning moment at the base.

A crane operator is performing a multiple lift to fly 6 steel beams up to the connectors at once. The crane's rated capacity for the current boom angle and radius is 15,000 lbs. Each beam weighs 2,000 lbs. The rigging hardware (slings and hooks) weighs 500 lbs. Is this lift legal and safe?

Workers are laying metal decking on the 4th floor of a steel-framed building. They are operating within a marked Controlled Decking Zone (CDZ). A worker steps out of the CDZ toward an unprotected edge (a 40-foot drop) to grab a dropped tool without tying off their harness.
