Teaching safety: 1000 students at a time

The safety training program for undergraduate lab students at the University of California, San Diego, Chemistry & Biochemistry Teaching Labs is based on self-study and gateway testing. Study materials are made available to the students, an optional safety lecture is provided and students are given venues to ask questions. Each lab student is required to pass an exam on basic lab safety and our specific laboratory rules. Our system for implementing this program and some of its problems are outlined.
