Provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), this historic 1943 image depicted a male construction worker situated in a crouching position atop a wooden beam, which was located on a construction site. He was about to affix the wooden plank using hammer and nails. Note that he was not wearing any protective eyewear, which would now be required in order to protect him against flying debris such as nails and wood chips. Today, he would also be required to wear a hard hat, which would have helped to protect his head from accidental blunt trauma.
