Final answer:
In conducting a chemical reaction with high temperature and pressure, you should have an emergency plan, label critical parts, work inside a fume hood, use blast shields for protection, and follow a written procedure. These measures are essential for ensuring a safe experimentation environment.
Step-by-step explanation:
When running a chemical reaction that involves high temperature and pressure, it's important to observe all safety protocols to prevent accidents and exposure to hazardous materials. In addition to wearing a lab coat, eye protection, and a face shield, there are several key precautions you should take:
- Emergency plan: Always have an emergency plan and the necessary supplies readily available to deal with any unexpected events or accidents.
- Labeling: It's imperative to label critical valves, shut-offs, and the direction of flow within your system to ensure safe and proper operation.
- Fume hood: Setting up your apparatus inside a certified laboratory fume hood is crucial for containing any harmful fumes or reactions.
- Blast shields: Employing polycarbonate blast shields can offer additional protection against unexpected reactions or explosions.
- Written procedure: Having a detailed, written, step-by-step procedure ensures that the experiment is conducted systematically and safely.
Additionally, never leave Bunsen burners and flames unattended, work in a well-ventilated room, and be alert and careful when handling chemicals and hot glassware.
