Social distancing for National Safety Month - plans?

Not sure if you guys do this at your company, but June is National Safety Month:

Normally at my company we would go to each department and put on a couple trainings/presentations and feed everyone lunch. Obviously that's going to be tough this year given the current situation. We plan on getting everyone T-shirts and gift cards to supplement lunch, but I'm wondering how we are going to do the remote presentations. Something tells me having one massive Zoom conference with an entire department is going to be tough (I just picture 30 people crowded around a computer monitor). Anyone have any ideas?
