    __//** Bunsen Burner Usage **//__  __**// To light a Bunsen burner: //**__  __//** Disposal  **//__   __//** Avoid Horseplay **//__ >>   
 * **DO NOT add __// WATER //__to __// CONCENTRATED ACID. //__ **
 * **<span style="font-family: Arial,Helvetica;">The heat generated may cause splattering. **
 * **<span style="font-family: Arial,Helvetica;">Your school probably will not allow you to use concentrated acids anyway, so keep this info in mind for future reference. **
 * **<span style="font-family: Arial,Helvetica;">If necessary to prepare certain solutions, DO add ACID to WATER (instead of the reverse order of addition). **
 * **<span style="font-family: Arial,Helvetica;">The heat generated will be less, but splattering still may occur. **
 * **<span style="font-family: Arial,Helvetica;">A good practice in all lab operations is to keep things at arm’s length. **
 * **<span style="font-family: Arial,Helvetica;">Always wear eye protection. **
 * **<span style="font-family: Arial,Helvetica;">Make sure the rubber hoses are __// firmly //__ attached. **
 * **<span style="font-family: Arial,Helvetica;">Both at the gas outlet and at the burner. **
 * **<span style="font-family: Arial,Helvetica;">Otherwise, the flame may "__// strike-back //__". **
 * **<span style="font-family: Arial,Helvetica;">Ask your teacher what this term means. **
 * **<span style="font-family: Arial,Helvetica;">If a "flame-out" nevertheless occurs, merely turn off the gas. **
 * **<span style="font-family: Arial,Helvetica;">Turn up the gas flow until you hear a gentle flow of gas. **
 * **<span style="font-family: Arial,Helvetica;">Light the burner by bringing the match UP from the base toward the burner nozzle. **
 * **<span style="font-family: Arial,Helvetica;">Remember: __ //down-to-up!// __ **
 * **<span style="font-family: Arial,Helvetica;">The match should be quenched with water at the faucet, **
 * **<span style="font-family: Arial,Helvetica;">NOT thrown into the waste directly. **
 * ** You may think the match flame is out, but **
 * **<span style="font-family: Arial,Helvetica;"> __//Fires may still occur//__ from the smoldering match. **
 * **<span style="font-family: Arial,Helvetica;">In a laboratory setting, horseplay, even if good-natured, is ****<span style="font-family: Arial,Helvetica;"> <span style="font-family: Arial,Helvetica;">__//absolutely unacceptable//__. **
 * **<span style="font-family: Arial,Helvetica;">No pushing! **
 * **<span style="font-family: Arial,Helvetica;">No shoving! **
 * **<span style="font-family: Arial,Helvetica;">__// Serious accidents //__all too often result involving the glassware or solutions in use. **

> __//** Have a Safe Year! **//__
 * **<span style="font-family: Arial,Helvetica;">Ask your teacher about the disciplinary measures in effect at your school for accidents in the lab resulting from horseplay. **
 * __//** <span style="font-family: Arial,Helvetica;">At the end of the lab period: **//__ <span style="font-family: Arial,Helvetica;">
 * **<span style="font-family: Arial,Helvetica;">Exit the lab in an orderly manner. **
 * **<span style="font-family: Arial,Helvetica;">Again: no running, no pushing, no shoving. **
 * <span style="font-family: Arial,Helvetica;">If the glassware present becomes broken, the situation is dangerous! **
