Safety
Safety is the responsibility of each person performing analytical
procedures. Because many of the procedures in this methods 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. These guidelines do not cover every
aspect of safety, but they are important for preventing injuries.
Material Safety Data Sheet
A material safety data sheet (MSDS) comes with the first shipment of all
products. The MSDS provides environmental and safety information about
the products. Always read the MSDS before using a new product.
Reading Labels Carefully
Read each reagent label carefully. Pay particular attention to the
precautions given. Never remove or block the label on a reagent 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.
Protective Equipment
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.
•
Gloves to protect skin from toxic or corrosive materials, sharp
objects, very hot or very cold materials, or broken glass. Use tongs or
finger cots when transferring hot apparatus.
