traditional campus laps in the convenience of your home

just like in the campus laboratory you must follow important safety procedures

before

during and after experimentation

follow these instructions and u too will have a safe and effective learning

experience

you'll notice micro scale techniques very small quantities of chemicals that

contributed to the safety of the experience

so make sure you read all the safety sections before starting your lab

activities

your instructor may have you fill out sign and send in the safety assessment

specific safety directions are also listed at the beginning of each

experiment in your lab manual

this video details the safety protocols you need to understand and employment

in order to conduct scientific experiments at home

in addition you will learn how the safety information and procedures you

performed working independently

compare to those safety guidelines procedures and equipment you would use

in campus laboratory

just like any campus lab there are three phases of laboratory safety measures for

the at home work

preparation

experiment

and clean up

each phase has unique safety considerations

the concepts and procedures will differ somewhat working at home compared to a

campus lab

but the objectives are always the same

at home

you are responsible for all safety procedures

your preparation

taking proper precautions and just good common sense will ensure your safety

set yourself to observation mode we're initializing the safety training

procedure now

let's go

the prep phase of your at home lab work requires gathering organizing and

preparing all of the materials you will need for your experiment

here are the steps

before starting each experiment read all information and instructions

review the related material safety data sheets an m_s_d_s_ for chemicals used

complete the emergency contact card simply set it near your telephone

whether at home or in a campus lab prepare yourself to do lab activities

wearing proper clothing

tying back care and removing dangling jewelry

make sure to wash your hands carefully before and after handling laboratory

materials

and where the safety gear

most people find your kitchen the most convenient place to work but garage or

study can also work

your workspace doors should be close and preferably locked keep any pets and kids

away from your work area and don't leave an experiment in progress unattended

unless it is in a locked and secure room

and never leave a flame or heat experiment unattended

in addition no eating drinking

cooking or smoking while you're doing your work

here are key factors to incorporate your workspace

protects your work table or surface by covering it with plastic sheeting or a

white garbage bag

and open window or stove exhaust fan are adequate to provide proper

ventilation

certain chemicals have noxious fumes they can be dangerous if inhaled

in sufficient quantities

and flammable vapors can become explosive if allowed to accumulate

enclosed space have some water available either resting bottled water or a

bathroom shower nearby

and i campus lap you'll find a safety shower and i've watched stations should

you ever splash or stock chemicals on yourself

or a fire starts

this is highly unlikely to happen since the micro scale quantities provided are

too small for major reactions

for experiments using chemicals keep a bag of sand or kitty litter on hand to

absorb and contain any chemical spills

keep sodium bicarbonate

baking soda on hand to neutralize spilled assets before attempting to wipe

them out

concentrated acids can cause serious burns

so neutralized then before cleanup

to help to prevent a painful injury

it's also a good idea to have a first aid kit handy

if you have a fire extinguisher know where it is in your home

take precautions and don't be careless when working with an open flame

examined glassware for any chips or breaks and it found discard immediately

pay attention when heating items

don't touch with their hands to avoid burns

some physics and geology experiments can involve the safety hazards of moving

objects

so always have ample room to conduct these types of experiments

you might want to tell other people in your household activities to ensure

everyone's safety

now do you understand that critical safety measures involved in the prep

phase you are ready to move on to the most exciting and fun part

the experiment

don't let your guard down though safety precautions must be followed throughout

all phases of your learning experiences

awareness is

your ultimate weapon again safety hazards accidents and emergencies during

your experience

you need to be aware of things that can happen so that you can prevent mishaps

react quickly if problems arise should an accident occurred the big boom a

full-scale chemical quantities in the laboratory

is a small poof

in your home environment

at home

or in a lab always where the appropriate personal safety gear for the experiment

you are doing

here is more detailed information about chemicals to keep in mind as you conduct

your statement

some chemicals can be corrosive

flammable and generally hazardous

red-hot all labels carefully and follow instructions

precisely

use only the amounts of chemicals needed for your experiment

never refill used chemical containers

use chemicals may be contaminated and you could end up with and unexpected and

potentially unpleasant reaction

some of the chemicals included are solvents

most solvents are highly flammable and should never be exposed to an open flame

examples are alcohols

toluene

ethers acetone and ethyl acetate

certain chemicals produced toxic fumes that can be dangerous if inhaled

never directly sniff a chemical

instead waft the vapors towards your nose with your hand

assets are chemicals that can cause severe burns some handle them with care

never add water directly to a concentrated acid

this generates heat

and can cause dangerous splattering

that is similar to what happens when you add water to hot oil

the proper way to make some acids with water is to follow the a_a_ rule

add acid

you should slowly add acid to water while stirring the water with the glass

rod

never the other way around

in addition to caution with chemicals remain away of fire hazards open flames

heated objects and burners can pose serious safety threats during experiment

here are some tips to keep in mind

never leave and open flame unattended

it only takes seconds for loose clothing or other items to catch fire

on a similar note

always extinguish heat sources when not in use

test metal and glass objects for heat

prior to handling in order to avoid parents

and be careful to only eat objects that are designed to be heated

certain class objects such as graduated cylinders and flasks are not going to be

heated

and can shatter when exposed to a heat source

is a glass objects shatters or breaks

don't risk a cut

by picking up the glass with your hands instead sweep the broken pieces

into a dust pan carefully dispose of them immediately

if a burn occurs

cold running water is the best treatment

followed by medical attention if necessary

there are important safety concerns to keep in mind if you are performing

biology experiments that include dissections

follow proper cutting and dissection procedures

slip of the sharp scalpel can cause a laceration

never cut items while holding them in your hand and always cut away from the

direction of your body

now you know what to be aware of all performing experiments

you're ready to get started

finishing the experiment does not signal the end of your lab safety

protocol

it signals the beginning of your final phase cleanup

during the cleanup dispose of all chemicals and dissection specimens

appropriately

used an unwanted my microscale chemicals can be flushed down the toilet or sink

and non-chemical items can be disposed of in the trash

wrap dissection specimens in newspaper and seal in plastic prior to placing the

trash wash your work surface and all laboratory equipment with dish detergent

and warm water

rinse equipment with distilled water and air dry glass objects clean pipettes by

drying up expelling distilled water several times

then while squeezing the bulb forcefully swing them in a downward arc

double-check that all materials have been properly cleaned and put away

store your lap out of reach of children and pets

congratulations you have successfully completed the safety training video

that before you go please keep in mind one final word of caution

that is just for female students

if you are pregnant or plan to become pregnant seek your doctor's advice prior

to performing the experiments

certain experiments may involve chemicals that can pose a risk

to your unborn baby

your doctor can tell you if it is safe to complete all of the experiments

required for your course

if you have any further questions regarding the important safety

measures required in using your lab discuss them with your instructor

or contact hands-on labs incorporated

thank you for watching
