NFPA 704:
List all the colors associated with this system
Blue - health
Red - flammability
Yellow- instability
White - “special “ only unusual reactivity with water and OX oxidizer are authorized here
Who regulates the manufacture and labeling of pesticides?
EPA
Pesticide labels:
Phrase assigned to each hazard category that describes the nature of the hazards.
Hazard statements
Pesticide label:
A symbol inside a diamond with a red border, denoting a particular hazard class such as acute toxicity/lethality, and skin irritation/corrosion
Pictogram
Pesticide labels:
One word used to indicate the relative severity of Hazzard and alert the reader to a potential hazard on the label and safety data sheet
Signal words
The GHS has two:
Warning- less severe
Danger - more severe
Pesticide labels:
Supplier identification-
EPA encourages, but does not require,_________on pesticide labels
Telephone contact numbers
Pesticide labels:
Lower categories of classification and unclassified products would not require pictograms or signal words under GHS. The current EPA system includes a third signal word which is used in addition to “warning” and “danger”
“Caution”

Proper Shipping name and the hazard class
This is a detailed information bulletin prepared by chemicals manufacturer or importer that provide specific information about the product
Safety data sheet
Senses:
This is definitely the safest of the five senses to use to detect a hazardous material
Vision
Senses:
This can also be used to detect information from a distance.
Hearing
Senses:
Gradual inability of a person to detect odors after initial exposure. Can be extremely rapid with some toxins such as hydrogen sulfide
Olfactory fatigue
Senses:
