Cotton dust rules now allow modern respirators, ending a 50-year-old mandate

The US Labor Department is updating its rules for respirators used in cotton processing plants. This change means companies can use newer, more effective breathing masks instead of only those approved decades ago.

For decades, cotton processing plants had to use specific types of respirators that were approved when the original cotton dust standard was written in 1978. This meant that even if better, more comfortable, or cheaper respirators became available, companies could not use them. The new rule allows companies to use any respirator that meets the general respiratory protection standard, opening the door for modern safety equipment.
