The first day of tech was the day to learn about safety. Safety is the most important part of engineering. Safety requires a lot of thought. First your eyes are probably the most important part of your body to stay safe. That’s why we use safety goggles. If anything flys into your eye could cause permanent damage.thats why safety goggles are important. Also you need to tie your hair back. Tying long hair back is important because there are a lot of hot materials in the lab. If your hair gets caught on these long materials then it could start a fire. Last but not least you need to overall just be cautious and try to stay safe when you’re in an environment with tools that are helpful if used safely.
