I finally this year, have found definitive evidence that chlorine levels of 50 ppm are NOT dangerous, even without stabilizer present: it turns out dermatologists have been using 50 - 100 ppm "bleach baths" (Google it!) for YEARS to treat eczema and other skin conditions, even in pediatric patients!

However, I can tell you that 50 ppm IS dangerous to swimsuits, unless you have very high stabilizer levels (> 200 ppm?).

In your pool, I don't see a stabilizer result, so I can only tell you that your chlorine levels aren't dangerous to YOU, but whether your swimsuit will be safe depends on the stabilizer level.
