Roseanne works in an emergency department at a hospital. During her shift, she is assigned to work with a chemical she has never used before. How should she identify how to safely work with the chemical?

Roseanne should consult the chemical’s Material Safety Data Sheet (MSDS), which provides detailed information about hazards, protective equipment, safe handling, and what to do in an emergency. The bottle label also gives important hazard information, but it may not include the full instructions she needs. A similar chemical may have different risks, and an unsourced Internet search may not provide reliable guidance.
