Safety is the responsibility of every analyst. Many of the procedures in this
manual use potentially hazardous chemicals and equipment; it is important to
prevent accidents by practicing good laboratory techniques. The following
guidelines apply to water analysis and are not intended to cover every aspect
of safety.
Read each reagent label carefully. Pay particular attention to the precautions
given. Never remove or cover the label on a container while it contains reagent.
Do not put a different reagent into a labeled container without changing the
label. When preparing a reagent or standard solution, label the container clearly.
If a label is hard to read, re-label promptly according to your facility's hazard
communication program.
Warning labels also appear on some of the apparatus used with the test
procedures. The protective shields with the COD Reactor and the Digesdahl
Digestion Apparatus point out potential hazards. Be sure these shields are in
place during use and observe the precautions on the label.
Use the right protective equipment for the chemicals and procedures. The MSDS
contains this information. Protective equipment may include:
•
Eye protection, such as safety glasses or goggles, to protect from flying
objects or chemical splashes.
