when fire extinguisher has expired in a generator room can we say that the risk is high or medium in health and safety?
I suggest that you Google up some Lightning-specific forums and ask away over there. I'm not going to pretend to own a Lightning or anything with a blower, but I promise you that Lightning folks don't gather over here.
Most christians don't fully believe in all what God has to offer so they just get into the motion of going to church and become religious. God can protect them but only if they rely in his promises. Doubt has no place with God.
