this part explodes on everything also when i made it specific what did i do wrong?

de = false
function touch(hit)
    local boom = Instance.new("Explosion")
    if hit.Name == "Baseplate"  then

        boom.Parent = game.Workspace
        boom.Position = part.Position
end
wait(3)
de = false
end
script.Parent.Touched:connect(touch)

it explodes on everything not only baseplate as i said it should
