Wikipedia › wiki › Harassment
Harassment that can happen anywhere but is most common in the workplace and schools. It involves unwanted and unwelcome words, deeds, actions, gestures, symbols, or behaviours of a sexual nature that make the target feel uncomfortable. Gender and sexual orientation harassment fall into this family.
By some definitions, you were harassing this employee. Obviously, not your definition.
I don't know you but I will say you seem to be concerned with yours and your fellow employees' safety. With that being said, if you feel the need to directly address an issue with another person's performance of duties, do so with a Steward present (away from management) and from a standpoint of protecting said employee from discipline (which he/she should appreciate) as well as the health and safety of others.
Your role as a CHSP member should never single out an employee. Address the root of the problem. The 70+ packages are not being properly highlighted to raise awareness. Your concerns log should reflect this.
