This first question asks you to make a list of at least three protective gear.
00:07
So i would say lab coat.
00:10
This is protective clothing to minimize the contamination.
00:15
Second is safety goggle.
00:17
The safety goggle is to provide eye protection because you might have spill or splash or sometimes aerosol.
00:29
So safety goggles protect the eyes.
00:31
And third one is obviously the gloves.
00:34
Gloves protect your hand from being contaminated by the bacteria and so also prevent it from transfer to between lab space.
00:43
So these are the three main protective gear.
00:46
Second, you want to find out how to dispose each of those items from a to e.
00:54
You have a certain choice of waste disposal.
00:57
The first one, used pipettes.
01:04
The used pipettes goes into the pipette canister.
01:13
So this is designed specifically for pipette b.
01:18
The glass slide that was stained.
01:20
So since it's glass, so obviously it's going to go into the broken glass and sharp container.
01:48
The third one is petri dish containing bacteria.
01:59
Since the petri dish has bacteria on it, so obviously you need to throw that away as a biohazard.
02:12
So those biohazard trash that will be autoclaved before being hauled away.
02:21
D clinix.
02:24
Since it's in your pocket and you never take it out, so it shouldn't have any contamination on it, so you should just store them as normal trash.
02:43
E, gloves that have contacted bacteria, dirty gloves.
02:55
So again, since these gloves have already got in contact with bacteria, obviously, again, again, same as the petri dish that contain bacteria, it will be treated as biohazard.
03:16
The next question, list in steps how you would transfer bacteria from liquid culture to a plate.
03:23
So very first step, you want to disinfect the work surface with disinfectant...
