Transcripts
that
chemicals and chemical processes form a
major part of our lives from the Cars we
drive to the foods we eat to the ways in
which we relax we depend on a vast array
of chemicals to make life easier safer
and more convenient chances are your
work brings you in contact with
chemicals and chemical processes even
the simple act of putting gasoline in
your vehicle means transferring a highly
flammable liquid from one container to
another and while the final product
provides enormous benefits chemicals may
be dangerous or even
deadly corrosives for example are often
used in the manufacturer of life-saving
pharmaceuticals these same chemicals
however can cause serious skin damage
blindness and even death
as dangerous as some of these chemicals
are you can handle them safely by
knowing what you're working with how to
handle it and what to do in an
emergency this program shows how to
identify certain chemical hazards handle
chemicals safely and how you should
handle emergencies involving these
chemicals you can identify a chemical
potential hazards in several different
ways including the type of Hazards it
presents its physical state and health
effects chemicals can present four basic
types of Hazards in the workplace they
can be fire hazards igniting and burning
easily they can be toxic or poisonous if
swallowed inhaled or absorbed through
the skin they can burn skin on contact
and they can react dangerously when they
come in contact with other
materials hazardous chemicals can be
solids such as sodium metal liquids like
gasoline or gases like chlorine the
effect a chemical has on your body can
be either acute or chronic depending on
the type frequency and length of your
exposure acute effects usually occur
rapidly as the result of short-term
exposure and typically do not last a
long time chronic effects develop over
time sometimes showing up many years
after the exposure they are usually the
result of repeated or long-term exposure
Benzene for example occurs naturally in
crude oil and natural gas is commonly
used as a solvent or raw material in the
manufacture of a number of products the
short-term or acute effects of benzene
exposure include severe skin irritation
a painful burning sensation and a
condition known as chemical pneumonia in
this condition Benzene is absorbed
rapidly through the skin causing your
lungs to
swell exposure to low concentrations of
benzene over a long period of time can
produce chronic effects including blood
disease chromosome damage and low birth
weight in
babies when handling chemicals knowledge
is your most powerful tool Begin by
recognizing the specific hazard or
hazards the chemical may present the
material safety data sheet or MSDS is
one of your best sources for information
on the chemicals you use it contains a
summary of a chemicals hazards as well
as proper handling use and storage
methods the MSDS also lists important
information for protecting you such as
permissible exposure limits the right
personal protective equipment fir
fighting techniques and emergency
procedures the first step in identifying
a chemical is to read the label each
chemical that arrives in your facility
must have accurate labels containing
specific information read the label to
discover a chemical's hazardous
ingredients the principal Hazard it
poses and the name and address of the
manufacturer who can provide further
information in addition the label
provides the chemical abstract service
or c number use this number when looking
up information about the chemical on a
computer or when there is a question
about the identity of the chemical it
may also be necessary when reordering
the
chemical in addition to identifying
labels each chemical container must have
a hazard label there are two major
labeling systems in use for identifying
a chemical's hazards one developed by
the US Department of Transportation or
do and one by the National Fire
Protection Association
NFPA the do system uses diamond shaped
color labels and placards that describe
the nature of the chemical Hazard
examples of do labels include both
flammable and non-flammable gases
flammable liquids and solids poisons and
infectious substances as well as
radioactive materials and miscellaneous
hazardous
materials the NFPA label is also diamond
shaped but is divided into four
different colored sections the red
section represents the material's level
of
flammability the blue section represents
the chemicals health hazards The yellow
section represents the chemicals
instability and the white section
indicates special hazards that cause the
chemical to become dangerous in a fire
such as reactivity with water or
oxidizers that cause fires to burn
violently for each of the primary colors
a number system on a scale of 0 through
four is used to describe the intensity
of the hazard for example when you see a
zero in the red flammability section it
means the chemical is
nonflammable however the number four in
the same section means the chemical is
highly flammable chemical manufacturers
or suppliers may have their own
customized Hazard identification so you
need to become familiar with the system
in your workplace also keep in mind that
while some chemical present multiple
hazards the label may only indicate the
most prevalent Hazard so stay informed
and take time to learn all hazards of
the chemicals you
use you can reduce the risks of
hazardous chemicals by using proper
handling and storage
techniques while specific requirements
vary from one chemical to another here
are some general guidelines that apply
to most hazardous
materials before you use any chemical
make sure you know what it is do not use
any chemical from an unidentified
container when transferring chemicals
use the proper container for each
material remember that the container you
are transferring the material to must
also be properly labeled make sure the
container is leak proof and sturdy stack
containers care so they won't fall be
sure they're not stacked too high
blocking aisles or obstructing emergency
exits treat cylinders containing
compressed gases as potential
explosives don't expose cylinders to
high temperatures excessive temperatures
can trigger rupture prevention devices
or cause
explosions when a cylinder is empty
promptly remove the regulator and
replace it with a protective cap and
mark the cylinder as
empty when moving or storing cylinders
secure them with straps or chains or
place them in an appropriate stand to
prevent them from falling never use a
cylinder that cannot be
identified flamable materials also
require special precautions here are
some rules for handling flammables carry
glass bottles containing flammable
liquids in a rubber Cradle to reduce the
risk of breakage keep keep ignition
sources away from the material use
static bonding and grounding procedures
when transferring flammables keep
flammables away from hot work or Sparks
and observe no smoking regulations in
areas where flammables are used or
stored oxidizers and flammables are a
dangerous combination store them well
away from each other to prevent violent
reactions in case of fire use NFPA
approved fireproof cabinets to store
flammable materials away from the work
area many accidents occur when chemicals
are being moved to and from storage
areas so use common sense and the
methods your facility has outlined when
moving hazardous
chemicals when working with any
hazardous chemical keep the area well
ventilated to prevent harmful Vapors or
dust from accumulating in the air
hazardous chemicals have four ways of
entering your body they can be absorbed
Through Your Skin inhaled ases dust
fumes or Vapors ingested or swallowed or
introduced on contaminated objects that
puncture your skin to reduce the risk of
exposure to hazardous chemicals you must
wear personal protective equipment or
PPE that is designed and tested for the
chemicals you're using some rubber
gloves for example can fall apart when
exposed to certain
corrosives some chemicals require aprons
or full body coverings to protect you
from splashes or
contamination you may need an air
purification device in areas where
normal ventilation will not protect you
from harmful Vapors these devices can
range from simple air filters to resp
operators or even a self-contained
breathing
apparatus in all cases protect your eyes
with safety glasses safety goggles or a
face shield protect your hands with
appropriate gloves neoprene gloves can
protect you from most corrosives or
solvents but don't guess your life and
health are at stake examine your gloves
for signs of wear or failure every time
you put them on glov can fail due to
permeation or a chemical seeping through
glove material or penetration when a
glove is torn or punctured look
carefully at the tips of the fingers and
between fingers for cracks pin holes or
excessive wear if there are any signs of
damage replace them make sure your
gloves fit properly gloves that are too
small can constrict the movement of your
hands while gloves that are too large
can get caught in machinery causing
major
injuries before removing your gloves
take the time to rinse them with clean
water to remove chemical residue this
will prevent your hands from coming in
direct contact with chemicals your
ordinary Safety Shoes may not protect
you against all chemicals corrosives for
example wear rubber boots rubber
overshoes or synthetic Rubber and acid
resistant work shoes to be safe check
the MSDS to ensure you are using the
correct combination of personal
protective equipment for your situation
your employer will provide the
appropriate PPE but it's up to you to
use it
properly no one plans accidents but you
can make plans to handle them your
facility's emergency action plan
contains spefic specific information for
handling hazardous material emergencies
including contact information evacuation
and rescue procedures and Reporting
guidelines learn the plan before you
have to use it your knowledge could save
lives and property if you apply it
quickly and properly in the case of
spills or leaks the haer standard along
with title three of the Superfund
Amendment reauthorization act or Sarah
May
apply has whopper or hazardous waste
operations and emergency response
establishes strict training level
guidelines when a dangerous spill or
leak threatens your workplace in
addition Sarah title 3 states that any
hazardous spill that releases more than
the threshold limit of a contaminant
into the environment must be reported
immediately to local authorities or
through approved notific ation
methods has whopper also prohibits
workers from participating in hazardous
waste operations and emergency response
activities unless they have received
proper training according to worker
protection standards in other words if
there is an emergency do what you're
trained to do and stay out of everyone
else's way if you don't you could make
things worse and become a casualty
yourself if a fire occurs that is small
enough to fight with a portable fire
extinguisher make sure you use the right
extinguisher for the type of fire you're
fighting and that you know how to use it
properly remember the pass system pull
the pin aim the nozzle squeeze the
handle and sweep from side to side at
the base of the
Flames if the fire becomes too large or
you start to run out of extinguishing
agent evacu valate the area
immediately finally when you're working
with or near hazardous chemicals always
make sure you know the location of
eyewash stations safety showers and the
number for the Poison Control Center if
your eyes are splashed by chemicals get
to the eyewash Fountain immediately hold
your eyes open in the water and flush
them continuously for 15 minutes for
larger splashes get to the safety shower
with without delay step into the running
water and remove contaminated clothing
while in the
shower you have the power to make
hazardous chemicals useful in many ways
you also have the power to use them
safely by following some basic
guidelines know what you're working with
read the label and MSDS and make sure
sure you understand the hazards and the
ways to avoid them know how to move
transfer and store the material safely
use the right PPE and use it the right
way know your role in case of emergency
know when and how to fight fires
involving hazardous chemicals just as
important know when not to fight them
and get help instead finally learn the
locations of safety equipment such as
fire extinguishers eyewash stations and
safety
showers knowledge your knowledge is the
key to keeping hazardous materials under
control you can make the difference and
keep your workplace safe for you your
co-workers and your community
