and kills mold and mildew, (3) durable and easy to shape, (4) poison, (5) can make you
sick if you breath or swallow
What is the definition of lead-based paint? - ANS-paint, varnish, shellac, or other
coatings on surface that contain more than 1.0 mg/cm2 of lead or more than 0.% lead
by weight
Name sources of lead exposure - ANS-lead-based paint, leaded gasoline, industrial
releases, soil; food; and water, pottery; crystal; and glassware, different jobs and
hobbies
When is lead paint a hazard? - ANS-when it chips or becomes dust of fumes
When is lead dust created? - ANS-(1) gets old and deteriorates, (2) surfaces are
broken, damaged, or disturbed, (3) surfaces are sanded or scraped. Lead dust and
particles tend to stick to surfaces

ANS-Millions
(true/false) doing lead abatement safely is very important - ANS-true
What does lead look like? - ANS-heavy, gray metal
Why was lead used? - ANS-(1) prevents corrosion, (2) kills mold and mildew, (3) is easy
to shape, (4) is strong, (5) blocks radiation, (6) blocks sound, (7) helps paint dry
,In ________, Ben Franklin wrote to a friend about work-related lead poisoning cases. -
ANS-1786
In the early _________, doctors found that lead-based paint caused reproductive
problems for workers and their families - ANS-1900s
Where can lead be found? - ANS-almost anywhere
What does lead pollute - ANS-air, soil, household dust, and any surface it lands on
(true/false) you can find traces of lead in most soil - ANS-true
How does OSHA set the limits of the amount of lead you can breathe when you are
working and what are they? - ANS-(1) Action level = 30 ug/m3 (2) Permissible Exposure
Limit = 50 ug/m3
1 gram = how many ug? - ANS-1,000,000 micro grams
1 gram (g) = how many mg? - ANS-1,000 milligrams
1 milligram = how many micro grams - ANS-1,000 micro grams
What is the Action Level? - ANS-the average amount of lead in the air over an 8-hour
period. this is the caution area
If you are exposed to an action level, what must the employer do? - ANS-must measure
the amount of lead in the air at least every six months or any time you change the
activity or work environment
What is the PEL? - ANS-Permissible Exposure Limit of 50 ug/m3 and means stop! This
is the highest level of lead that you are allowed to be exposed to.
If you are exposed to an PEL, what must the employer do? - ANS-monitor lead in the air
every 3 months or any time you change the activity or the work environment
When does OSHA say you need a blood test? - ANS-when you first work with lead
How is blood measured? - ANS-micrograms of lead per deciliter
, What does MUC stand for? - ANS-Maximum Use Concentration which is the highest
amount of lead a respirator can handle under the OSHA lead standard
What is the Temporary Medical Removal Protection? - ANS-OSHA says if you have two
blood levels about 50 ug/dl two weeks apart, your employer must give you work to do
that does not expose you to lead
What is APF? - ANS-Assigned Protection Factor
How does lead enter your body? - ANS-breathe or swallow
(t/f) when lead reaches your blood, it attaches to red blood cells in the area where iron
and oxygen are. If you body does not get enough iron, lead will attach to the red blood
cells more quickly. Then, red blood cells cannot cannot carry oxygen. - ANS-true
Lead can be stored in bone tissue for more than _______ years - ANS-30
Lead that stays in your body is called? - ANS-body burden
(true/false) If the lead goes from the bone back into the blood, it causes problems all
over again - ANS-true
A pregnant woman's body absorbs _____ of the lead she takes in; whereas, adults
mostly ______. - ANS-50%; 10%
Children absorb nearly ______ of the lead they take in - ANS-50%
__________ are a very high risk of lead poisoning - ANS-toddlers (age 1 to 3)
(true/false) the health effects of lead poisoning are often difficult to recognize - ANS-true
Can lead poisoning cause permanent damage? - ANS-yes
Name two kinds of tests to monitor blood levels - ANS-(1) blood level test (2) ZPP test
(Zinc Protoporphyrin)
Which is the most accurate blood test? - ANS-blood level test and shows what you have
been exposed to in the last 6 to 8 weeks
