At so many companies, they have the employees take blood bourne pathogens training, by lecture, video, or online module.

So when the following happens:

Revelation 8:7 The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up.

Will they totally freak out? As they'll have blood coming down upon them, not knowing whose or what the blood is. Will they all be terrified that perhaps they'll catch something horrible from that blood?
