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
