00:00:05.350 --> 00:00:08.840
Good day in the lab
00:00:13.985 --> 00:00:16.459
You mind to throw your cup of coffee
00:00:17.072 --> 00:00:19.258
and to shut down your phone
00:00:19.492 --> 00:00:21.508
before entering in the laboratory
00:00:25.202 --> 00:00:27.326
You let your bag at the entrance
00:00:27.432 --> 00:00:29.776
in a locker if it is available
00:00:29.992 --> 00:00:32.901
Otherwise, you will put your bag under your bench
00:00:33.522 --> 00:00:35.675
You won’t be alone in the laboratory
00:00:36.016 --> 00:00:37.866
The safety of everyone
00:00:37.926 --> 00:00:41.012
will depend on the behaviour of each person
00:00:48.517 --> 00:00:52.127
You need to dress up to work in the lab
00:00:52.237 --> 00:00:53.347
you are wearing long pants
00:00:53.357 --> 00:00:54.550
or a long skirt
00:00:54.577 --> 00:00:55.890
with closed shoes
00:00:56.750 --> 00:00:59.120
You are also wearing
00:00:59.600 --> 00:01:01.210
a closed lab coat
00:01:01.270 --> 00:01:02.840
with the sleeves dropped
00:01:04.570 --> 00:01:06.296
safety glasses
00:01:06.675 --> 00:01:10.216
to protect you from eventual projection of chemicals
00:01:10.495 --> 00:01:12.996
even if you have regular glasses
00:01:16.616 --> 00:01:18.269
and the right protecting gloves
00:01:18.460 --> 00:01:21.905
according to the product you will manipulate
00:01:27.039 --> 00:01:31.440
So, the work of today is
00:01:31.488 --> 00:01:33.609
an acid dilution
00:01:33.639 --> 00:01:34.539
in water
00:01:34.669 --> 00:01:36.770
Then, what are we going to do?
00:01:37.702 --> 00:01:40.022
You have taken note of the experiments you are going to do
00:01:40.042 --> 00:01:41.572
before coming in the lab
00:01:42.042 --> 00:01:45.827
So you know which collective protections you are going to use
00:01:45.877 --> 00:01:47.757
Today you will work with acids
00:01:47.857 --> 00:01:51.237
So, you will work under a fume hood
00:01:53.248 --> 00:01:55.314
You are sitting in front of the hood
00:01:56.228 --> 00:01:59.398
Mind to organize your bench in the most productive way
00:01:59.468 --> 00:02:02.764
because you cannot pass your head inside the hood
00:02:05.221 --> 00:02:08.403
Label carefully each product containers
00:02:08.691 --> 00:02:11.053
to avoid any confusion
00:02:18.552 --> 00:02:20.022
The sash position
00:02:20.032 --> 00:02:22.815
is very important to ensure a safe air flow
00:02:23.362 --> 00:02:24.832
If the sash is not closed
00:02:24.892 --> 00:02:27.787
the air flow will be disturbed
00:02:27.992 --> 00:02:30.952
and this could be dangerous for the manipulator
00:02:31.312 --> 00:02:33.729
If the sash is well placed
00:02:33.989 --> 00:02:35.529
the air flow will be good
00:02:35.589 --> 00:02:38.217
and the manipulations will be safe
00:02:41.829 --> 00:02:43.770
Despite these safety measures
00:02:43.985 --> 00:02:46.265
it is possible to drop off some reagents
00:02:46.285 --> 00:02:48.610
a solvent, an acid or a base
00:02:50.238 --> 00:02:52.463
In that case you have to change your glove
00:02:52.480 --> 00:02:54.968
and throw it in the right bins
00:02:55.382 --> 00:02:58.198
then you have to clean your bench if it is needed
00:02:59.552 --> 00:03:01.924
If you had been in contact with the product
00:03:01.952 --> 00:03:04.624
rinse you with water during several minutes
00:03:04.632 --> 00:03:06.822
by using the safety shower if it is necessary
00:03:06.852 --> 00:03:09.324
and warn another manipulator
00:03:10.074 --> 00:03:12.034
If an accident happens
00:03:12.064 --> 00:03:14.897
first aids have to be provided
00:03:15.753 --> 00:03:19.860
Good day in the lab
00:03:21.130 --> 00:03:24.890
