Attorney received dismissal of summary judgment in a products liability case. The plaintiff was burned on 9% of his body as the result of a propane gas flare-up as he attempted to light a cooking appliance on his lunch truck. As a result, he spent 12 days in a hospital burn unit. Although our client's gas valves were used on some of the appliances on the truck, we were able to establish through deposition testimony that the source of the escaping gas was a shut off valve not manufactured by our client.
