Workers can use modern respirators for methylenedianiline exposure, not just old ones

The US Labor Department is updating its rules for respirators used to protect against methylenedianiline, a chemical used in plastics. This means workers can now use a wider range of modern, more effective respirators, instead of being limited to older models.

For decades, specific rules forced workers to use outdated respirator types for certain chemicals, even when better technology existed. This change allows companies to use any respirator that meets general safety standards, as long as it protects against the specific chemical. It removes a bureaucratic hurdle that kept safety equipment from keeping up with technology.
