Assuming your state follows the Federal hazard communication standard (29 CFR 1910.1200), see 1910.1200(b)(4), which simplifies the requirements for people like mailroom staff who only handle sealed containers
under normal operations, and I believe exempts such staff from needing an explicit list of hazardous chemicals, if I am reading the exemption in 1910.1200(b)(4)(iii) correctly.

Hello, all,
I have a new question prompted by a recent webinar I attended.
I am wondering how folks approach HazCom training for mailroom personnel. Since the chemicals they handle have not yet been added to our inventory records and with it the accompanying SDSs, I am wondering how to meet the requirements for
lists of chemicals they could be exposed to. I recognize that a general approach to interpretation could help, but it seems like that would not meet the program requirements. Also in a practical sense, substances with out-of-the-ordinary hazard profiles pass
through their hands with some regularity so I'm wondering how to help them understand those, just in case.
Anyway, any incite or suggestions you might have so very much appreciated,
Thanks,
