welcome to a new era of interactive learning lab experiences that mirror
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
