Fit testing for respiratory protection

Fit testing for tight-fitting respiratory protection according to AFS 2023:11, effective January 1, 2025

As of January 1, 2025, the Swedish Work Environment Authority (Arbetsmiljöverket) requires that all users of tight-fitting respirators undergo an individual fit test in accordance with AFS 2023:11. This requirement is essential to ensure that the respirator seals properly and provides maximum protection against harmful particles and substances.

Why is a Fit Test important?

Respirators that do not fit properly can create a false sense of security and expose users to hazardous substances. Incorrect usage or poor fit can result in serious health risks, including exposure to dangerous chemicals, dust, and other airborne contaminants. Therefore, it is crucial that companies follow the new guidelines and ensure that their employees are adequately protected.
A properly conducted fit test ensures that the mask:
  • Seals tightly against the face without leakage.
  • Functions effectively under working conditions.
  • Prevents health risks such as inhalation of harmful particles and gases.
Many workplaces, such as construction sites, chemical industries, and healthcare facilities, require strict protection to prevent long-term health issues for employees. Conducting a proper fit test demonstrates that an employer takes workplace safety and employee health seriously.
