READ THE LESSON
From rule to routine
A CHP is the practical translation of the Lab Standard for your specific lab: the procedures, controls and responsibilities that keep your particular hazards in check.
SOPs are the working heart
Standard operating procedures describe how a defined hazardous task is performed step by step. Before a new procedure, the CHP is where you check it's approved.
