Safety is the first concern and the collective responsibility of everyone in the chemistry lab. Accidents most often result from an indifferent attitude, not using common sense, and/or a failure to follow instructions that leads to mistakes. Be sure you know and follow the safety precautions that will protect you and others from harm:

• Familiarize yourself with the hazards of the chemicals and apparatus you are using.
• Read and follow all instructions carefully. When in doubt about a procedure, ask your instructor.
• Maintain an attentive attitude. The lab experience should be enjoyable but serious, with no playing around or using distracting electronic devices.
• Know where to find and how to use all emergency equipment such as fire extinguishers, safety showers, and eyewash fountains. Report any use of equipment to your instructor.
