The building I worked at doesn't enforce it. I wound up in the hospital for an overnight stay, stress tests the next day, etc., due to someone’s fragrances. My boss understood and did what she could, then finally suggested I consider telecommuting. That has been such a blessing for me, you can't even know.
I don't really want laws to ban fragrances but whatever chemicals these companies are putting in them needs to be exposed. I can handle true perfumes, flowers, and such. Even all the oily odors from an auto shop or junk yard is completely bearable. But the cocktails these fragrances are are practically poison.
Wanna bet that the crap that makes you ill comes from China?
I have the same problem, and when several women wear several different overwhelming scents, it is painful to be at work. Even though I have told my office mate about my sensitivity, she from time to time slips and wears perfumed lotions or something.
Someone I was in conversation with many years ago told me that the problem was that so many of the fragrance manufacturers include hay oil in the mix, and that is what initiates the allergic reaction. Don’t know if this is it or not.
