The Occupational Safety and Health Administration (OSHA) of the American Wyoming state has proposed a new rule that would mandate all workers within 75 feet of a well bore to wear flame-resistant clothing.

The new dress code, if approved, would change the way several people dress at oil and gas drilling sites.

The proposed regulation is expected to get mixed response from oil and gas drilling companies, according to the Petroleum Association of Wyoming.

The majority of companies are already using flame-resistant clothing and they would welcome the new regulation.

However, there are some other companies that would like to use the flame-resistant clothing on as-needed basis. These companies argue that the new regulation, if implemented, would mean an imposition of them, owing to the weight, cost and high rate of turnover of such clothing.

In addition, some other companies are in favour of hazard assessment, based on which it could be mandated whether to put on the flame-resistant clothing or not, the Association said.

If the new rule is approved, OSHA would post signs near drilling sites that remind workers of wearing flame-resistant clothing.
