An employee approaches the occupational health nurse to discuss safety related to working with toxic substances. The employee is asking about measures to prevent inhalation exposure of the substances
Which statement by the nurse will decrease the patient's exposure risk to toxic substances?
A) "Position a fan blowing on the toxic substances to prevent the substance from becoming stagnant in the air."
B) "Wear protective attire and devices when working with the toxic substance."
C) "Dilute the toxic substance by spraying it with water forcefully.
D) "Store toxic substances in tightly sealed, unlabeled containers."
Ans: B
Feedback: When working with toxic substances, the nurse must wear or use protective devices such as face masks, hoods, or industrial respirators. Toxic substances should be enclosed and placed in restricted areas, and should be clearly labeled for identification purposes. Dust control often leads to pneumoconiosis and can be controlled by spraying the area with water. Never position a fan directly blowing on the toxic substance as it will disperse the fumes throughout the area. Also, the toxic substance should not be diluted.
