__// Use of the FUME HOOD //__   __//** Safety Shower **//__   **__// ON FIRE //__, position yourself (or your lab mate) under the safety shower. ** 
 * **Not every school will have a fume hood available. **
 * **If your school has a FUME HOOD—use the HOOD for reactions that give off vapors, especially smelly vapors. **
 * **The draft of the HOOD will sweep away vapors so that the lab itself maintains reasonable air quality. **
 * **Again, not every school will have one. **
 * Shower should be used for __// dire EMERGENCY  //__ only!  **
 *  **If you (or a lab mate) is**
 * **Pull the handle—a deluge of water will result. **
 * **<span style="font-family: Arial,Helvetica;">Flames will be rapidly extinguished. **
 * **<span style="font-family: Arial,Helvetica;">But: there is probably no floor drain. **

__//** <span style="font-family: Arial,Helvetica;">Broken Glass **//__ <span style="font-family: Arial,Helvetica;"> <span style="font-family: Arial,Helvetica;">
 * The safety shower should also be used if you suffer a __//** massive spill **//__of a __** dangerous chemical **__on yourself, and need to get it off rapidly.
 * However, in a high school laboratory, this will seldom be necessary.
 * **<span style="font-family: Arial,Helvetica;">Sweep it up right away **
 * **<span style="font-family: Arial,Helvetica;">Don’t track in it all period. **

 * **<span style="font-family: Arial,Helvetica;">Place the broken glass in a "SHARP’S CONTAINER. **
 * **<span style="font-family: Arial,Helvetica;">This is a thick walled carton, that will be sealed and discarded as such. **
 * **<span style="font-family: Arial,Helvetica;">If such a container is not available, a milk carton is an acceptable substitute. **

__//** <span style="font-family: Arial,Helvetica;">Materials Safety Data Sheets **//____//** <span style="font-family: Arial,Helvetica;">(MSDS)  **//__ <span style="font-family: Arial,Helvetica;"> <span style="font-family: Arial,Helvetica;">
 * **<span style="font-family: Arial,Helvetica;">When a chemical is purchased, the supplier will send a MSDS sheet. **
 * **<span style="font-family: Arial,Helvetica;">The MSDS sheet lists the known dangers of the chemical in question. **
 * **<span style="font-family: Arial,Helvetica;">Your school should keep a file of MSDS sheets. **
 * **<span style="font-family: Arial,Helvetica;">Many people feel that the MSDS sheets overstate the dangers. **
 * **<span style="font-family: Arial,Helvetica;">Make sure you use the right MSDS sheet for the right chemical, as many chemical names sound similar. **
 * **<span style="font-family: Arial,Helvetica;">The catalogs of major suppliers also list useful safety information. **

__//** <span style="font-family: Arial,Helvetica;">Safety Warning "Diamond" **//__ <span style="font-family: Arial,Helvetica;"> <span style="font-family: Arial,Helvetica;">
 * **<span style="font-family: Arial,Helvetica;">The entrance to the area where chemicals are stored should carry a "diamond" safety warning label, or another similar label. **


 * **<span style="font-family: Arial,Helvetica;">Know the significance of these symbols. **
 * **<span style="font-family: Arial,Helvetica;">You will see these frequently in adult life. **
 * ** <span style="font-family: Arial,Helvetica;">RED is FIRE DANGER **
 * **<span style="font-family: Arial,Helvetica;">rated on a 0-4 basis. **
 * **<span style="font-family: Arial,Helvetica;">If, for example, ether is present, a very high rating of 4 would be indicated. **
 * **<span style="font-family: Arial,Helvetica;"> Yellow indicates REACTIVITY danger. **
 * **<span style="font-family: Arial,Helvetica;">often " WATER REACTIVE " dangers **
 * **<span style="font-family: Arial,Helvetica;">Sodium metal, if present, would require a 4 rating. **
 * **<span style="font-family: Arial,Helvetica;">Sodium represents a danger to firemen, who might come busting into this area with a high pressure hose. **
 * ** <span style="font-family: Arial,Helvetica;">BLUE <span style="font-family: Arial,Helvetica;">represents HEALTH HAZARDS, **
 * **<span style="font-family: Arial,Helvetica;"> WHITE signifies specific hazards, e.g. oxidizers, acids, bases, or corrosive materials. **
