What is a requirement for effective use of respiratory equipment?

For effective use of respiratory equipment, being fit-tested is essential. This process ensures that the equipment forms a proper seal on the face of the user. A fit test checks that the respiratory protection is adequately sized and effectively prevents contaminants from entering the breathing zone. If the mask or respirator does not fit well, it may leave gaps that allow unfiltered air to enter, compromising the protection intended. Ensuring a proper fit maximizes the effectiveness of the respiratory protection, ensuring the user's safety, particularly in environments where hazardous substances are present.

In contrast, using respiratory equipment only in emergency situations would not involve the proper training and regular checks necessary for routine safety. Sharing equipment can lead to cross-contamination and inconsistent fit, further undermining safety standards. Additionally, respiratory protection is crucial during cleaning procedures in contaminated environments, as cleaning might disturb hazardous materials that could become airborne.
