Which of the following is incorrect when performing overhead work?

a.
clean workspace and clothing using compressed air.
b.
secure all tools and materials
c.
store materials in building under construction farther than 6 feet or hoist way/floor openings and more than 10 feet from an exterior wall
d.

Letter A. It is incorrect to use compressed air in order to clean the workspace or the clothing especially when performing overhead works. It is unnecessary for a person to clean a workplace and his or her clothing while in the middle of work. Securing all the tools and materials, putting up some additional protection like toe boards, and storing materials 6 feet away from a building under construction are all considered as part of the safety and health regulations for construction.
