*(all) set. (to do something) prepared or ready to do something. (*Typically: be ~; get ~.) Are you set to cook the steaks? Yes, the fire is ready, and I'm all set to start.
How long will the odor last from our newly installed cellulose insulation? The odor is kinda of like a mild ammonia smell and is only noticeable when we're running the a/c.
Hydrogen sulfide rapidly fatigues the sense of smell, so while your nose is a good early detector, it cannot be relied upon over time. If you notice a sudden and a strong onset to the rotten egg odor, move to fresh air, and contact your local health department.
