Yeah - my wife being an OSHA girl freaked out on me too. You can pick up a lead test for about $30 and it's instant (its usually a 10 pack). If there's multiple layers use a bit of sand paper to expose each layer. If there is lead it will turn red. If it doesn't, you then test it on the control paper (which does contain lead). If it doesn't turn red after that - use another tester.
