CHM151LL Lab 4 — Labster Virtual Labs: Lab Safety and lonic/Covalent Bonds
Name: —
Section Number: ~
Part 1: Lab Safety Simulation
Questions to answer during the lab:
1. If you are having trouble during the virtual lab you can click on the LabPad. The LabPad has four
tabs, name them. (4 pts)
a. Home, theory, media, and mission
2. What were the 5 hazards you located during this virtual lab? (5 pts)
a. The emergency door was blocked
Workbench is cluttered, needs to be tidy
©P oo o
Sink is full of dirty dishware
Fume hood was not closed
Hazardous chemicals need to be stored away properly
3. What is the purpose of a biohazardous waste bin? (2 pts)
a. To safely dispose of chemical wate that may be contaminated or if it’s harmful to the
environment
4. There was a chemical spilled on the workbench, why didn’t you just use water to clean up the
spill? (2 pts)
a. Because, it was an acid spil and it was also corrosive. So you first need to neutralize it
with a base and they you can scoop it up into a platic bin to discard it.
5. Once you complete this simulation, you will be shown a screen to verify 100% completion and your
score. Exit and go to your Grades tab on the left-hand menu and take a screenshot that shows your
score on this lab simulation as well as your name and section. Paste the screenshot below. Remember,
you must earn an 80% score on the lab simulation to earn credit. If you do not achieve an 80% on your
first attempt, redo the lab simulation as needed to earn the 80%. Once you receive at least an 80% on
the lab simulation, you will earn full credit for this screenshot. (10 pts)

Follow up questions:
1. Name 2 personal protection items that need to be worn in a chemistry laboratory. (4 pts)
a. Lab coat, safety goggles
2. What do each of the following hazard symbols mean? (8 pts)
1 3 5 7
2 4 6 8
1 - flammable 5 — Corrosive
2 - Harmful 6 — Toxic
3 — Compressed Gas 7 — Oxidizing
4 — Serious Health Hazard 8 — Explosive
2. Why is it dangerous to wear contact lenses in the lab? (4 pts)
a. Because of if hazardous chemicals gets into your eyes the contact lens can trap the
substances making it worse, they are delay you from flushing out your eyes in case of an
emergency.
