When should you use level c personal protection equipment?

Level C personal protective equipment (PPE) should be used when the type of airborne exposure is known, but the concentration and type of exposure are not immediately dangerous to life or health (IDLH). This level of protection is appropriate in situations where there is a potential for hazardous materials but where the specific risks can be managed with appropriate PPE, including chemical-resistant clothing, gloves, and a full-face respirator. It is essential to conduct a risk assessment to ensure that the chosen PPE adequately protects against the identified hazards.
