Once you are sensitized there is no safe level much like peanut allergies. The allergic reaction can be super-excessive & that is what kills people, like 10 days of vomiting & dehydration or it starts with the nose being plugged and ends with the lungs filling with fluid and you die by drowning. Not a good thing.

The foam that is used from the cans you get at home depot to fill cracks and Gorilla Glue is also another irritant that can cause a tiny percent of the population to become sensitized, after the initial reaction if they are exposed even to the tiniest amount their lungs very quickly fill with fluid and they usually are overwhelmed & end up dead.
