A science laboratory can be a safe environment if students are alert and cautious of important laboratory safety procedures. Lab instructors generally have specific rules and guidelines that must be followed while working in the laboratory. One of the most important concerns in the lab is heating and fire safety. Bunsen burners and alcohol lamps are frequently used in experiments, which make them potentially dangerous if students are not careful when handling them. It is recommended that students be familiar with general fire safety rules before entering the lab environment. Be sure to check out <a href="http://www.elearners.com">online college courses</a> and how you can get into an excellent career.
When using heat sources such as a hot plate, Bunsen burner, or candle, be sure to wear safety goggles. Often, labs require students to wear safety goggles to prevent damage to their vision. Experiments that use heat sources can leave a student open to the danger from heat, flames, and smoke that is usually released from heated chemicals. If something should get into your eyes, have your lab partner or a fellow classmate locate the lab instructor immediately.
Before entering the lab segment of your science class, you will learn about chemicals and chemical reactions as well as the compatibility and incompatibility of specific chemicals in relation to heat. Consequently, students are instructed to never heat any chemical, or anything for that matter, unless instructed in the directions and by the lab teacher. Certain chemicals are calm when in a cool state but have the potential to become volatile when in a heated state.

Keep all combustible materials away from flames. Learn which materials, like cloth, paper, etc. are highly susceptible to burn, so that you can keep them away from all heating sources. The same goes for chemical solutions. Never use a flame or spark near a flammable chemical. This could cause an ignition that could be explosive and way out of control.
Students should receive proper instruction on how to operate and control a laboratory burner. Instructors should thoroughly familiarize students with operating procedures, including how to light the flame and how to adjust the flame to a specific level. Burners can remain hot, even after use, so it is best not to touch them at any time. Be cautious - burners left unattended can be a major fire hazard; therefore, never leave a burner lit and unattended.
Take precaution when heating chemicals in a test tube. They tend to splash and ooze out when they are under boiling conditions. Properly position the tube so that the mouth of the test tube does not face you or any other students. This precaution deters the possibility of someone getting burned if the chemicals splatter out. In addition, never heat a liquid in a closed container; the expanding gasses have the potential to blow up the container.
Working with heat sources require the constant moving of hot objects. Before touching or holding a container, there is a way to measure the degree of heat an object encompasses. Place the back of your hand near the heated object. If you feel heat sensation on the back of your hand, the container is too hot to pick up without protection. Use gloves or an oven mitt to pick up a container that has been heated.
Safety rules exist so that students appreciate the use of natural elements, like fire, in an enclosed environment. Lab instructors vary, so their safety rules will too. While in your college lab course, be sure to get thoroughly acquainted with the rules that govern your laboratory use.
