An electric cigarette lighter, shielded from the weather by a small roof, is an odd sight at a corner of a Beaumont, Texas, oil field. So dreaded a hazard is fire here that workmen are forbidden to carry matches. Violation of this rule is considered almost as serious an offense as it would be in a powder plant. To encourage its observance, the owners of the field installed the lighter, just outside the danger zone, for the convenience of employees who wished to smoke during the noon hour. As a result, the field boasts an enviable safety record.
