where is the majority of lead stored in the body - ....ANSWER....bones (80-90%)
how often does EPA require refreshers - ....ANSWER....every 3 years
XRF radiation sources and half lives - ....ANSWER....Co 57 - 9 mo half life
Cd 109 - 15 mo half life
What was the finding in the NHANES study? - ....ANSWER....they found BLL decreased
as lead was taken out of gas
What levels are considered child lead poisoning? - ....ANSWER....2 consecutive tests
15-19 ug/dL
one test 20 ug/dL or higher
TSCA (Toxic Substances Control Act) - ....ANSWER....act that regulates existing
chemicals that pose an unreasonable health risk. Its objective is to allow EPA to
regulate new commercial chemicals
-controls certifications, training, real estate disclosure, and lab accreditation
**required EPA to set standards under 40 CFR Part 745
what determines CDC level of concern - ....ANSWER....87.5% of children have less
than the suggested level of concern
what acronym describes radiation safety - ....ANSWER....ALARA- as low as reasonably
achievable
,time, distance, shielding
how often should leak testing be done, for dosimeter and wipe test on XRF -
....ANSWER....every 6 months
how many paint samples/XRF shots should be taken at an assessment -
....ANSWER....one testing combo per room; if applicable, can only do one moving one
non moving.
test other testing combo if they have different painting histories
**for ex. if a room has multiple doors and all of them have the same substrate and
painting history, you can only test one of them. in addition, you dont need to test every
component of the door, just one moving and one nonmoving
what is a testing combination - ....ANSWER....room equivalent, substrates, building
components
how often to calibrate the XRF - ....ANSWER....beginning of assessment
every 4 hours
end of assessment
after every time if has been turned off
when can you halt testing a certain testing combination - ....ANSWER....after 5 positive
results of that combo, must assume all others are positive
how often to send in a blank and spiked wipe sample - ....ANSWER....1 every 50
samples
what do you do to the standard after taking a composite dust sample -
....ANSWER....divide standard by 1/2 number of subsamples
what do you do to the standard after taking composite paint chip samples -
....ANSWER....divide standard by number of subsamples
primary prevention - ....ANSWER....identify hazards before children are exposed
secondary prevention - ....ANSWER....blood lead screening to find EBLL
what is RRP - ....ANSWER....Renovation, repair, painting
tells requirements for firm +renovator certification
what is the minimum amount of dust samples taken at a home assessment -
....ANSWER....4 rooms: 1 floor, 1 sill in each
what is the biggest predictor of a child BLL - ....ANSWER....dust
, what is the LBPPPA - ....ANSWER....Lead based paint poisoning prevention act
defined LBP as 0.06%
what is RCRA - ....ANSWER....governs federal hazardous waste disposal (not
residential)
LBP is hazardous material if TCLPP is greater than or equal to 5 ppm
indemnify - ....ANSWER....to pay or promise to pay someone an amount of money if
they suffer damage or loss
tort law and the 2 types of liability under tort law - ....ANSWER....A civil wrong
-negligence
-vicarious liability
What is the one thing an assessor should never say - ....ANSWER....that a dwelling is
lead free; should say there was no LBP identified
errors + omissions insurance - ....ANSWER....covers midjudgments during an
assessment
General Liability Insurance - ....ANSWER....An insurance policy that provides protection
against claims involving bodily injury and property damage to third parties.
types of general liability insurance - ....ANSWER....occurrence: coverage whether policy
period is over or not, as long as the claim occurred during the policy period
claims-made: coverage only during the policy period
what is the minimum of units to test for multifamily housing - ....ANSWER....21+ if built
before 1960/ if unknown age
10+ if built 1960-1978
**if fewer than the amount above, treat each as a single family home
how to number/label a site map - ....ANSWER....# and label clockwise (room equivs,
components, sides of house)
XRF threshold - ....ANSWER....amount at which an XRF considers a reading to be
positive
what to test in multifamily housing - ....ANSWER....-interior and exterior of each unit in
the sample
-representative sample of common areas (one of each testing combo)
what info do you need to choose your sample in multifamily housing - ....ANSWER....-
complete list of units, unit numbers, and common areas
-painting history
-lists/drawings of common area components
