I can say that they were suited up in isolation because that would be the proper protocol, and because doing otherwise defies the purpose of the hazmat suit.
You dumb ****. Tell us again how all PPE is worn all the time? I dare say I have more knowledge of OSHA and safety regs than you could dream of.
STUPID **** the basic PPE must be worn at all times while on the job site, If you don't think every person on the job site doesn't have to wear their PPE you don't know jack shit. I do this for a ******* living dumb ****
And like a typical dumb ****, you are avoiding the actual topic.
Let me try again.
Do you wear a hazmat suit at all times at work?
Look at the OSHA Standard. It requires PPE if there is a hazard present nor is there likely to be a hazard. In the picture in the OP, there is no hazard for the man wearing street clothes. Nor is there likely to be a hazard.
I spent 12 years as the Director of Safety for an operating unit of (at the time) the largest utility construction contractor in the world. I have more certifications and training from OSHA than I am willing to list. I was part of the team that wrote the main safety manual for that company.
If there is no hazard present, or likely to be present, you are not required to wear PPE. Most companies make entire work sites PPE required spaces, but that is the company, not OSHA. For OSHA it depends on the hazards present or likely to be present.
