I ran across a sign that the lung association had created, and while I am glad they are doing something , I found the message and visual required some tweaking.
Of course, the lung association didn’t come up with the term “sensitive”, it’s what is used in human rights laws, but it seems to have created an impression in the public’s mind that chemical and environmental sensitivities are trivial, and not disabling or even life threatening like they can be.
It also needs to be said that signs without enforcement are endangering lives and perpetuating harm, systemic accessibility barriers, discrimination, and forced isolated segregation for those who are disabled by any or repeated exposures.

For more information on how fragrance/scent-free policies benefit everyone, not just those who are ‘sensitive’, check the other posts on this site.
In a growing number of areas it’s now the law to remove accessibility barriers, and fragranced/scented products ARE accessibility barriers.
Be fragrance-free. It’s good for you! It’s good for me.
Seriously "Sensitive" to Pollution 
I prefer signs that list specific products which are offenders. For example, most people don’t consider their deodorant or their laundry products.
We’ve got that covered too… A number of different signs are available on this site, as well as a checklist to share with people who think it’s only perfume or cologne:
Excellent. Concur re. term ‘Sensitive’ – it diminishes the disability & Real health impact.

There are 3 PDF signs here that people may be interested in seeing even though they are provincial from the Government of Newfoundland and Labrador:
