Ugh, respiratory protection questions are the worst. There are so many different elements to consider. I'm going to have to really focus and eliminate the options that don't make sense. Let me think this through step-by-step.
Okay, I've got this. The first measure for respiratory protection is always ventilation, so the answer has to be B. Respirators and PPE are important, but they come after ensuring proper ventilation. I feel good about this one.
Hmm, I'm a bit unsure about this one. I'll have to think it through carefully. Is it possible the answer could be A, using respirators? Or maybe D, ensuring PPE is in good condition? I'll have to review my notes.
This seems like a straightforward question about respiratory protection. I'm pretty confident the answer is B - the use of general and local ventilation.
