When asking someone is they can 'handle' something it means can they deal with or take it. Mildly spicy food may be very hot to some people and very weak to others.
Spicy food is different between different cultures and cuisines so what may be spicy in one isn't in another. This is a good question to see what they think is spicy to get an idea as to how much spiciness they can take. I hope that this helps. :)
