Werner Containerized Hazmat Question

I was offered a position here from Florida to work Werner Hauling Containerized Hazmat for them in the South East area.

Was wondering if anyone else on here does this, and if you can help elaborate on what exactly type of possible Hazmat material, we would haul? They said I also needed a TWIC card, (which I have already) and it's home on the weekends 1.5 day.

Thanks so much in advance for any help
