“The Right To Know”
POLYTECH HIGH SCHOOL
Natural Resouces and Environmental
Sciences
What is “The Right To Know” ? A law that states every
person has a right to information about materials in their workplace that may be hazardous.
This is a FEDERAL LAW and applies to all states
This law took effect in January 1, 1985
It is also known as the “Delaware Hazardous Chemical Information Act”
YOU MUST PASS THE “RIGHT TO KNOW” TEST WITH AT LEAST AN 100% IN
ORDER FOR YOU TO PARTICIPATE IN THE SHOPS AT POLYTECH.
Training and testing is provided yearly!
ANY QUESTIONS???????
How does it apply to school? School is your workplace.
This means you have a right to know if there are hazardous materials in this building.
Your teacher or employer are required to tell you if
you work with materials that may be hazardous.
This is known as Hazard Communication
Any chemical or product is considered Hazardous if it has a warning label.
So, even something that causes a rash can be hazardous.
It does not mean that it has to cause death or a major health problem/condition.
Student Rights You have the right to:

How chemicals affect us
Depend on the toxicity and the exposure to that chemical
Acute toxicity:
after a short exposure an immediate effect may be experienced.
Chronic toxicity:
Over a long period of exposure.
Both acute and chronic conditions can result in permanent injury
What is a carcinogen? any substance that produces cancer or can aggravate
cancer
commonly known carcinogens include asbestos, radon,
certain pesticides, arsenic, and tobacco smoke and
smokeless tobacco
Ultraviolet rays from the sun
Chlorine
Chlorine is a disinfectant in water for bathing, drinking, and
swimming. (its byproducts are capable of causing a range
of illnesses, including lung cancer)
According to researchers, ingestion of, and bathing,
showering, and swimming in chlorinated water can all lead
to increased incidence of cancer of the bladder.
Toxicity - LD50 and LC50;
Comparison of Acute Toxicity
LD50 is –
Abbreviation used for the dose which kills 50% of the test population.
LC50 is –
Abbreviation used for the exposure concentration of a toxic substance lethal to half of the test animals.
LD50 is expressed in milligrams per kilogram of body weight of the test animal (which must be mentioned).
LC50 is expressed in millilitres per kilogram of body weight of the test animal (which must be mentioned), exposed to the substance by inhalation during a specified period.

Proper Cleanup Procedures
Proper Eye Wash Procedures
Hold eyelids open using the thumb and index finger to help ensure that effective rinsing has occurred
Water stream should NOT be directly aimed onto the eyeball, but aimed at the base of the nose
Flush eyes and eyelids with water or eye solution for a minimum of 15 minutes. “Roll” eyes around to ensure full rinsing
Seek medical attention immediately!
Dial 911.
The sooner medical attention can be given, less chances of sustaining permanent damage or blindness

Aim low. Point the extinguisher at the base of the fire.
Squeeze the lever slowly and evenly.
Sweep the nozzle from side-to-side.
NO chemicals are to be discharged into the sewer system or thrown in the trash
Rinse And Dispose Of Chemical
Containers Safely
Triple-rinse a container
Fill it one-fourth full with clean water
Shake or swirl the container vigorously to rinse all inside surfaces
Empty rinsate into the spray tank and let it drain for 30 seconds. Then repeat
Do not dump pesticide container rinse water on the ground.
Empty all rinsate into your spray tank and apply it to your fields
Puncture the bottom so the container cannot be reused
Do’s and Don’ts of Safety
Do wear proper safety equipment

Rachel Carson
Pesticide Safety
Rachel Carson
(1907-1964) Silent Spring is a book
written by Rachel Carson
published 1962.
Widely credited with
launching the
environmentalism movement
Silent Spring facilitated the
ban of the pesticide DDT in
1972 in the United States.
WILDLIFE SPECIES EXPOSED
TO CHEMICAL INTOXICATION
Almost Extinct!
Silent Spring The book claimed detrimental effects of pesticides on
the environment, particularly on birds.
Carson accused the chemical industry of spreading
disinformation, and public officials of accepting
industry claims uncritically.
She proposed a biotic approach to pest control as an
alternative to DDT, claiming that DDT had been found
to cause thinner egg shells and result in reproductive
problems and death.
Silent Spring was named one of the 25 Greatest
Science Books of All-Time by the editors of Discover
Magazine
According to Time in 1999:
Carson was threatened with lawsuits
This meticulous scientist was accused of being
a "hysterical woman" unqualified to write such a
book.
A huge counterattack was organized and led by
Monsanto, Velsicol, American Cyanamid—
indeed, the whole chemical industry—duly
supported by the Agriculture Department as
well as the more cautious in the media.
A former chemical industry spokesman Robert
White-Stevens stated,
"If man were to follow the teachings of Miss
Carson, we would return to the Dark Ages, and
the insects and diseases and vermin would
once again inherit the earth.“
In a 2005 essay, "The Harm That Pressure Groups
Can Do", British politician Dick Taverne was damning
in his criticism of Carson:
Carson didn't seem to take into account the vital role
(DDT) played in controlling the transmission of malaria
by killing the mosquitoes that carry the parasite (...)
It is the single most effective agent ever developed for
saving human life (...)
Rachel Carson is a warning to us all of the dangers of
neglecting the evidence-based approach and the need
to weight potential risk against benefit:
It can be argued that the anti-DDT campaign she
inspired was responsible for almost as many deaths
as some of the worst dictators of the last century.
However, DDT has never been banned for anti-malaria use
Carson argued in "Silent Spring" that:
No responsible person contends that insect-borne disease should be ignored.
The question is whether it is either wise or responsible to attack the problem by methods that are rapidly making it worse.
The world has heard much of the triumphant war against disease through the control of insect vectors of infection
But it has heard little that the insect enemy has been made actually stronger by our efforts.
Even worse, the list of resistant species now includes practically all of the insect groups of medical importance. ..
Malaria programs are threatened by resistance among mosquitoes
Practical advice should be 'Spray as little as you possibly can' rather than 'Spray to the limit of your capacity' ...,
