Here is today's Ham Shack Safety Tip:

  If you smell gas in the shack, get to the shut off valve, and turn
  it off. Evacuate everyone from the property, and call the Fire
  Department and the Gas Company. Do not re-enter the structure
  until it has been checked for safety. One spark or open flame
  could trigger a fiery, fatal, huge, explosion.
