Do you know everything you need to know about the 10 most frequently cited Occupational Safety and Health Administration standards? In this series, we’re exploring the most common OSHA violations, one by one. Keep reading to learn how to avoid a respiratory protection violation and protect your workforce from airborne risks.

The OSHA Standard For Respirator Use: What It Is

OSHA’s requires employers to have a respiratory protection program when employees need respiratory protection. Before wearing a respirator, workers must have a medical evaluation first using a mandatory medical questionnaire or an equivalent method. Workers must also be fit tested before wearing a respirator in the workplace.

OSHA definition:

“The employer shall provide a medical evaluation to determine the employee’s ability to use a respirator, before the employee is fit tested or required to use the respirator in the workplace. The employer may discontinue an employee’s medical evaluations when the employee is no longer required to use a respirator.” (Source)

Simple definition:

Respirators are a must in workplaces that expose employees to hazardous airborne contaminants. But wearing a respirator can put an extra burden on your body. Workers with underlying medical conditions may be at risk if they work while wearing one. So the Occupational Safety and Health Administration (OSHA) has requirements before any employee can wear one.

Medical Evaluations

The requirements for medical evaluations include:

Fit testing

Conduct quantitative or qualitative fit testing for all employees required to wear either positive or negative pressure tight-fitting facepiece respirators. This includes both air-purifying and atmosphere-supplying respirators operating in either a positive or negative pressure mode. It does not include loose-fitting facepieces.

Conduct additional fit testing if an employee experiences a change in a physical condition that could affect the seal on a tight-fitting facepiece respirator. This requirement is triggered by a physical change:

Why Violations Happen

Violations can occur when companies do not implement the following components of OSHA’s Respiratory Protection Program:

Signs You’re at Risk of a Respiratory Protection Violation

What You Stand to Lose When Respiratory Protection Violations Happen

Indirect costs:

  • workers’ compensation claims from workers exposed to toxic air
  • lost productivity due to illnesses and injuries caused by airborne contaminants
  • legal and compliance fees
  • decreased morale
  • negative publicity and reputational damage

Direct costs:

OSHA penalties can exceed $16,550 per violation—and as much per day for every day the issue hasn’t been fixed by OSHA’s deadline. The fine for a willful or repeated violation can be 10 times as much.
