A safety contract should include practices that directly reduce lab hazards: labeling all containers, tying back long hair, and wearing safety goggles at all times. Bringing a cell phone or laptop into the lab is not a substitute for following safe lab procedures and may create distractions or additional hazards. Therefore, the best set is 1, 2, and 5: choice B.
