Students with open skin wounds on their hands must wear gloves during lab activities Never carry hot equipment or dangerous chemicals through a group of students Never taste anything or touch chemicals with your hands (unless instructed to do so)

Eating or drinking from lab equipment is not permitted Never look into a test tube, or point it in the direction of any person Keep hands away from face, eyes, and clothes while using solutions, specimens, equipment, or materials in the lab

Never smell any chemicals, unless cautiously from a distance NEVER pour reagents back into bottles Keep work areas clean. Floor and aisles should be kept clear of equipment and materials
