Read the following information from a Material Safety Data Sheet (MSDS) about the chemical hydrochloric acid (HCl).“Skin Contact: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.”Based on this information, which is the most important thing to do right away if a student spills HCl on his shirt?
Answer
A
Remove the shirt, and rinse the skin with water.
B
Remove the shirt, and find a sink to rinse it in.
C
Get help from a classmate immediately.
D
Call 911 to get medical attention immediately.
Explanation
The MSDS says to remove contaminated clothing while immediately flushing the skin with plenty of water for at least 15 minutes. So the student should take off the shirt and rinse the skin, not focus on rinsing the shirt or finding help first. Choice A, “Remove the shirt, and rinse the skin with water,” matches these immediate steps.
