“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.

MSDS MSDS is an acronym for -

Material Safety Data Sheet.

It contains important information about hazardous substances.

There is an MSDS sheet for every chemical/substance that is manufactured and has potentially hazardous ingredients.

MSDS sheets are kept in the Right-to-Know book

What color is the Right-to-Know book that is kept in each shop and where is it located?

Orange note book labeled Right-to-Know on the book shelf by the book bag room

MSDS

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

To operate a fire extinguisher,

remember the word PASS:

Pull the pin. Hold the extinguisher with the nozzle

pointing away from you,

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

Keep tools clean, organized and in good working condition

Keep work area clean and organized

Store all chemicals in a safe and properly ventilated area

Provide proper labeling on all chemicals

Don’t take unnecessary chances

Do Not pull mowers backwards

Do not fill fuel tanks while running

Do not run engines in a closed room

Never pour chemicals into water

Do not drink water from garden hoses

If you wake up looking like this,

don’t go to work!

Steps to Prevent the Spread of Flu

Cover your mouth and nose with a tissue or elbow when you cough or sneeze

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' ...,
