7. What is a "sensitive area"? Name four examples of sensitive
areas that you must be especially careful to protect when you are handling
herbicides.
a. Sensitive areas are sites or living things in
environments that are resistant to injury by an herbicide. Some examples
of sensitive areas include: places where pesticides can't get into ground
water or surface water; homes, schools, playgrounds, hospitals, and other
places where people are present; places where there are animals--endangered
species, bees, other wildlife, livestock, pets: places where crops, ornamental
plants, or other sensitive plants are growing: and areas where food or
feed is processed, stored, or served.
b. Sensitive areas are sites or living things
in environments that are easily injured by an herbicide. Some examples
of sensitive areas include: places where pesticides might get into ground
water or surface water: homes, schools, playgrounds, hospitals, and other
places where people are present: places where there are animals--endangered
species, bees, other wildlife, livestock, pets; places where crops, ornamental
plants, or other sensitive plants are growing; and areas where food or
feed is processed, stored, or served.
c. Sensitive areas are sites or living things in
the environments that are easily injured by an herbicide. Some examples
of sensitive areas include: places where pesticides can't get into ground
water or surface water; homes, schools, playgrounds, hospitals, and other
places where people are present; places where there are unprotected mineral
deposits; places where crops, ornamental plants, or other sensitive plants
are growing; and areas where food or feed is processed, stored, or served.
d. Sensitive areas are sites or living things in environments that
are resistant to injury by an herbicide. Some examples of sensitive
areas include: places where herbicides might get into ground water or surface
water: places where people are not allowed to be present; places where
animals rarely inhabit; places where crops, ornamental plants, or other
sensitive plants are growing; and areas where food or feed is processed,
stored, or served.

b. carbon dioxide, ammonia, hydrochloric acid
c. carbon dioxide, water, hydrochloric acid
