Health Focus
Part 1 of 2: Your Skin

OSHA's electrical safety guide puts it plainly: "Burns are the most common shock-related injury." And electrical burns are "among the most serious burns and require immediate medical attention."
OSHA lists three kinds, and one accident can cause any combination of them:
• Electrical burns. Current flows through tissue or bone, and the heat it generates damages the body from the inside.
• Arc or flash burns. The intense heat of an electric arc or explosion near the body burns you without touching anything.
• Thermal contact burns. Skin touches overheated conductors or equipment, or clothing catches fire from an arc.
The skin can be deceiving. The Merck Manual is direct: "The absence or severity of external burns does not predict the presence or severity of internal electrical injury." A burn can look small and neatly outlined on the skin while the current has done irregular, deeper damage underneath.
Wet skin changes the path. Merck explains that skin resistance varies a lot. Dry skin tends to take the energy as a surface burn. Moist skin lets current go deeper. Wet hands at a wellhead are the setup for the worse injury.
What happens underneath. High current can kill muscle. Damaged muscle releases substances that can injure the kidneys. In severe cases, swelling inside a limb can build pressure that cuts off its own blood supply (compartment syndrome). None of that shows on the surface on day one.
Treat any electrical burn as an emergency. Mayo Clinic says to get emergency medical help for burns caused by electricity. That holds even if the mark is the size of a dime.
Tomorrow: what to do in the first minutes, and when a burn belongs at a burn center.
Key Takeaways:
• Burns are the most common injury from electric shock.
• Electrical, arc, and thermal burns can all happen in one accident.
• A small mark on the skin can hide serious damage underneath.
• Every electrical burn gets emergency medical care.

The Week in Review
This week's notebook lines. If you can say it out loud to a helper without looking, you have it.
Safety Focus: Overhead Power Lines and Mast Raising
• Overhead power line contact is the leading cause of workplace electrical deaths, and in many cases the line was in plain sight.
• Every overhead line is energized until the utility says it is dead and visibly grounded.
• Electricity can arc to a mast that never touches the wire.
• Ten feet is OSHA's minimum for lines 50 kV and below; 20 feet or more is the better crew standard, and higher voltages need more.
• When the operator cannot judge clearance, a spotter watches the line and nothing else.
• If the rig contacts a line, stay inside the cab unless fire forces you out; then jump clear without touching rig and ground at once, land feet together, and shuffle away.
Knowledge Share: Subsurface Geology Analysis
• Cuttings show what came out of the hole; geophysical logs read what is in the wall, and you need both.
• Clay reads high on gamma and low on resistivity; clean fresh-water sand reads the opposite.
• SP and normal resistivity need an open, fluid-filled hole, so log before you case.
• Correlate wells by elevation, never by depth.
• Cuttings at the surface came from higher than the bit is now, so correct for lag.
Keep a running notebook. A 2021 University of Tokyo study found stronger brain activity during recall when people had written on paper than when they used a tablet or phone, and they finished writing faster too.
