I made a dish with habenaro in it, and quite a few. Washed my hands a few times during the cooking process after I finished handling the peppers. Then I went to the bathroom and had a rude awakening.

I saw a vid from Gordon Ramsey that using freshly squeezed limes to rinse your hands works against the spicy.

Like twenty years ago, I learned that the hard way... By putting in my contact lenses. To me ages to make the connection, because I didn't even touch the food, just ate in a restaurant.
