pressure relief valve

I have a question on pressure relief valve on a gas water heater. 
My question is: If there is a leak in the gas water heater, and I want to minimize the damage, this is what I am going to do to prevent any flood damage:
1. shut off the incoming water to the water heater;
2. Tun on the hot water faucets in the house to let water come out quickly.

Do I have to do anything with the pressure relief valve?
thank you so much for your answers.
