Prepare for the NRCC Chemical Hygiene Officer exam the way it is actually asked
This module prepares you for the National Registry of Certified Chemists (NRCC) Chemical Hygiene Officer examination: 150 multiple-choice questions in three hours. Most of its questions ask you to recall something exact, such as an OSHA section number, a definition or how often something is done. A few ask you to apply a rule or work a short calculation.
It is built for people who have taken, or are taking, the Chemical Hygiene Officer Pathway. The pathway teaches the material. This module does not teach it again; it prepares you for the exam.
