 * LABORATORY SAFETY **


 * //__ General Laboratory Safety: __//**

.
 * Accidents in the chem lab, as in the home or work place, can be prevented: **
 * **Stop to think!. **
 * ** Common sense  will help, if exercised **
 * ** What will be the consequences of what I do next? **
 * **If in doubt, ask the teacher. **
 * The following scenes illustrate some difficulties as well as downright dangers that you could face in lab, mostly due to failure to observe ordinary safety precautions, and common sense. **

//__[|Personal Protective Equipment]__//


 * **Many states require // by law // that students wear approved safety goggles or safety glasses when in the lab. **
 * **This is an __//absolute//__ "__// MUST //__"! **

//__[|Proper Attire]__//
 * **The following is not acceptable! **


 * ** Avoid floppy garments; avoid things that dangle **


 * ** These get tangled up in equipment or glassware and cause accidents **
 * ** Avoid long, loose hair styles for the same reason. **
 * ** When Bunsen burners are in use, long hair sometimes catches on fire **


 * ** The Safety Code of most schools will not approve of open footware; so avoid sandals, thongs **



//__[|Handling Of Acids And Bases]__//
 * **Many schools will require the use of personal protective equipment, such as gloves. **
 * **However, cream-colored latex gloves (see photo) are no longer recommended (due to allergic responses). **
 * **"Vinyl" gloves or "nitrile" gloves (often green or blue in color) are preferred. **



//__[|Fire Extinguisher Operation]__//
 * **For even more dangerous liquids, thick "nitrile" gloves should be used. These are very safe, but heavy and ungainly. Also, they become slick, when wet, and it is easy to drop things. **
 * **You probably will not use dangerous materials in middle school. **
