Transcripts
we reached the sixth part of our lesson
this is jovi lassa your chemistry for
engineers
lecturer
there
so after this discussion
and we will now cross out chemical
safety because we're almost
done with it you are now ready for
assessments which will come
shortly after this presentation
this lesson oops okay
this lesson is scheduled to be tackled
during the first week of the semester it
is now our second day which is the last
day of the week
and yeah we are doing it fairly we are
doing it as scheduled so we do not have
some backlogs which is a good indication
that we are still
on track okay
this particular lesson gives us a brief
discussion on the personal protective
equipment
commonly used in laboratories and how to
get your cells repaired during
emergencies
these topics are the last two parts of
our discussion
under chemical safety and we are right
now on the seventh and eighth part of
our
resource next to it is the list of
references at the end of this lesson
you are expected to be able to
demonstrate
knowledge on the use of personal
protective equipment for chemical safety
and your preparedness sharing
emergencies
from our previous discussion we learned
that chemical hazards
that may possibly lead to chemical
incidents but
with a proper implementation of hazard
controls to risk can be lowered down
one of the methods controlling the
hazard as we have learned is through the
use of ppe
and knowing what to do in case of
emergencies as part of the
administrative controls in the hazard
hierarchy of
control right chemicals may be swallowed
accidentally through contaminated hands
food or even cigarettes the process is
called
ingestion we can also enter to our
bodies
through breathing the process of
inhalation
some can pass through the skin and eyes
into the bloodstream the process of
absorption
and with heart with sharp objects
our skin may get punctured which is the
way for the chemical to be injected into
the bloodstream
this core are what you call the routes
of
exposure to the chemicals
this gave birth to the five
classifications of the
personal protective equipment
as can be seen here in our illustration
this includes ppes that protect the
respiratory
respiratory system you have here the
mask
and then the head eyes and face
protection so you have the helmet
the safety glasses and then you also
have some
earmuffs for the hearing
hand and arm protection you have the
gloves for torso protection you have the
vest
and foot and leg protection isd safety
shoes
at chemical laboratories the common ppes
that are used for the respiratory
protection
are the filtration respirators that
filter airborne
airborne particles that
then we have chemical cartridge devices
for filtering chemicals and gases
the cartridges are that are attached at
the sides
this one are selective
hence appropriate specifications
should be checked before using it there
are also times however
not very often when self-contained
breathing apparatus
are also employed for the eye protection
safety glasses are used whenever there
is a chance
of objects striking the eye on the other
hand
when working with liquids splash goggles
are
employed however when splash hazards is
high
or you are working with chemicals are
particularly dangerous
face shields are employed as an addition
to the splash
goggle for added protection
there are several types of gloves that
are being used in the laboratory for
hand protection each kind are used
depending on the type of chemical hazard
that the user is exposed to for dry
powders and aqua solutions
disposable latex nitrile and vinyl
gloves are commonly used
reusable neoprene rubber gloves are
those that should be used
when handling corrosives solvents
alcohols and oils
when when handling non-halogenated
organic solvents
the nitrile globes are the appropriate
type to be utilized
it is also puncture and abrasion
resistant viton gloves
are better used when handling
chlorinated
and aromatic solvents while detail
rubbers
are the ones that are appropriately used
when dealing with aldehydes
ketones and esters these three are
organic substances you may check on your
general chemistry
how each of them differs for extreme
temperatures reusable
uh thick makeup gloves such as snowmax
and zx
are recommended for use
common gowns that protects the body
during laboratory quirks
can either be made of cotton
polypropylene
and a cotton poly blend this is
synthetic cotton and
polymer however there are also
specialized laboratory coats and gowns
available
such as those that are made up of
polyethylene
which are liquid this is done and are
used
for high hazard biological materials so
these are the ones that
our medical practitioners are using
to protect themselves against the kovid
19 virus okay and we also have
the lab coasters are made up of
spawn-bonded olefins which are used when
dealing with particulates and
biological samples
when working with pyrophoric and
flammable
fire retardant laboratory codes should
be worn
and chemically resistant apron can also
be employed during general works
they are of different types and are used
in accordance with anticipated
chemical exposure closed shoes
and safety shoes are recommended to be
used to protect the feet from hazards
such as
chemical spills there are safe tissues
that are market with a lot of
specifications such as
fracture resistant water resistant
anti-static
anti-sleep oil resistant and
the likes but we must remember that the
use of the personal protective
equipments
has its own limitations such as those
the ones shown on the following
illustrations wearing a defective ppe
offers no protection
such as the damage heart shown in the
hot
damage hot hard hat shown in the full
tone
in addition to the damaged part it
doesn't have a strap that will hold
it in place ensuring that the head is
fully covered
while in use improper wearing of ppe may
not give maximum protection
the man in the photo is the usual
scenario that we see during this
pandemic right
people seem not to understand the use of
the face mask is for them to protect the
respiratory system
in which the nose is the primary route
of
exposure the ppe may be used
uh may because rather of an additional
hazard
in the photo a cellophane wrapped around
the worker's face was used as a ppe but
may cause some suffocation
which is also dangerous to his health
and remember ppe is our first line of
defense
but it does not prevent an accident from
occurring while working inside the
laboratory
eyewash and shower stations are located
10 seconds from the workstation
where a chemical hazard is available
this
are being utilized during chemical
splashes we have this at the chemistry
laboratory
at the main building of the pup
but in seya we don't have this uh still
in case of burns and small cats
we need to look for laboratory first aid
kits and treat ourselves accordingly
and we can go to the nearest clinic or
hospital as
the need arises in case of laboratory
spillage
know the property of the substance first
you can check on the
msds before you you are to deal with it
make sure to use the appropriate spill
kit available
and protect yourself with appropriate
personal protective equipment
confine the spill clean it up and
properly
dispose it if the spill is hazardous
you might as well label that
the spill kit as a hazardous
substance check on the labels of the
available fire extinguishers near the
workplace in case of fire
make sure that you are using the
appropriate type
class a fire extinguishers are used to
extinguish
ordinary combustible materials such as
paper cardboards
and plastics class b's
are for flammable and combustible
liquids such as
kerosene and gasoline for fires from
electrical equipment
class c fire extinguishers are the most
appropriate to use
and class these are those that are
employed with fires from combustible
materials found in
chemical laboratories
remember to prioritize your lives always
think safety first these are the lists
of the references that were used in this
particular discussion
thank you for listening always stay
safe all right
the first lesson we only have five
lessons to both
congratulations for finishing the
two hour lecture on chemical safety
i hope that you are not ready for
assessment
wherein you're going to play as the
safety officers
of your own household since you're not
going into the laboratory
laboratories because we cannot
go out yet from our room from our other
from our house
due to the pandemic let us
let us apply whatever learnings we have
inside our
home so experience
being a safety officers for
it's up to you for how many days are you
going to use it so i'm sending you the
checklist
the things that you're going to do and i
hope that you're going to send the
material
your output before the deadline because
as i mentioned during the orientation
i don't like my students to be so use of
so many
excuses just because they are not
scheduling their tasks and they love to
procrastinate because as future
professionals that
is not a good attitude that
you will you know i mean the
procrastination is not a good attitude
that
you are to practice because uh
you're not submission on a specific
period of time may affect
the whole project okay so there you have
it see you next time
in our first topic in thermodynamics
which is the classification of different
fuels that are commonly used in the
industries there you have it bye
