If the blocks are moving, look up. Learn the fluid path. How mud gets from the pits to the bit and back to the pits. Walk those lines and learn about the mud and the pumps. Don't put your hand anywhere you wouldn't put your dick. Don't look for the key to the v door. There isn't one. Be aware and alert. Shit happens quick and everything can kill you. Empty your pockets before working around the floor. Count pipe. Know how much pipe is on location so you will always be able to count it and found figure out where your at in the hole. Get a tally book. Write shit down. Ask someone how to fill out a kill sheet. Make a hand not a face.
