Explanation:
1. Preparing for the Lab:
Reading the experiment before arriving allows students to understand the procedure, safety measures, and potential hazards. It ensures efficiency, minimizes confusion, and enhances safety awareness. Washing hands before the experiment is good practice but does not replace proper preparation. Listening to others or reading upon arrival is too late for proper readiness.
2. Student Responsibility in the Lab:
Each student must prioritize both personal and collective safety. Being alert to potential dangers and assisting others when necessary can prevent accidents. Ignoring others or assuming complete personal responsibility is unsafe, as laboratory hazards affect everyone.
3. Pregnancy or Medical Conditions:
Consulting with an instructor before working in the lab is crucial. Some chemicals or conditions may pose risks to pregnant individuals or those with health concerns. Protective measures, alternative assignments, or additional guidance may be necessary to ensure safety.
4. Emergency Evacuation:
Turning off gas valves and electrical equipment prevents potential explosions, fires, or further hazards during an emergency. Cleaning workstations and picking up materials are not priorities in an urgent evacuation. Immediate safety actions should take precedence over routine cleanliness.
By adhering to these correct practices, students can ensure a safe and productive lab environment while minimizing risks to themselves and others.
