After a debate that spanned several months, the Wyoming Occupational Safety and Health Administration announced on February 4, 2013 that all workers within 75 feet of an oil or natural gas well bore in Wyoming must dress in flash fire resistant clothing.

A primary concern from many smaller and mid size drilling companies that oppose the ruling, is that the cost of flame resistant clothing is too high. Larger drilling companies, for the most part, have policies that mandate the use of FR clothing already.
While the financial cost of FR clothing is substantially higher than non-FR work wear, companies should also consider factors such as comfort. Increased weight and inability to wick sweat from the skin are common downfalls to less expensive FR garments. These comfort deficiencies can lead to increased levels of heat stress, and in turn can possibly cause lost time accidents and lost production time. Furthermore, lack of comfort breeds non-compliance. Workers who aren't comfortable have a tendency to "cheat" - rolling up sleeves, unbuttoning shirts, or simply taking their FR off completely. When considering flame resistant clothing for your company, research products that provide a high level of comfort and compliance - and you'll easily provide a greater return on your investment.
