No one is going to die a toxic death unless they stand over it and breath while it burns. You torch it, walk away and eat lunch, come back after the fire has gone out. If that worries you, stand a good distance and watch, but it's not like the fire will continue and melt the subframe. It's steel. Have to be a little hotter to do any damage. Once the bushing falls out on it's own you throw a hose on it, done.
