What are three potential uses of exposure assessmentresults? |
Determine the need for health hazard controls. Build oradd to the longitudinal exposure record (LER). Demonstrate regulatory compliance. |
|
|
According to the AIHA exposure assessment model, what actions are taken when an exposure’s acceptability is uncertain? |
Gather further information. |
|
|
What similarities do the AF Model and AIHA Modelshare? |
Identify exposures through routine and special surveillance, determine the acceptabilityof the exposures, and establish controls when needed. |
|
|
What are the results from a Screening Assessment usedfor? |
The resultsof the screening assessment determine what further action, if any, should betaken. |
|
|
What type of sampling is defined as an “equal probability of selecting any exposure period for any worker in the SEG duringthe interval of the assessment?” |
Random sampling. |
|
|
Is it possible to assess worker exposure without collecting samples? If so, briefly describe how If not, briefly describe why collecting samples is always necessary. |
Yes.Exposure may be estimated using surrogate data and models to make a predictive assessment. |
|
|
In the absence of a formal OEEL from a regulatory, authoritative orinternal source, an industrial hygienist or other health risk assessors oftencan identify a “________ OEEL” to help differentiate an acceptable from an unacceptable exposure. |
working |
|
|
The lack of OEELs has prompted some private organizations or industriesto develop ________ OEELs, based on toxicity testing or their handling experience. These standards do not have the effect of the law, and may not bebased on scientific consensus. |
Internal |
|
|
These are set and enforced by governmental agencies and have the supportof the law behind them.
|
Regulatory |
|
|
Although they are not developed for use as legal standards, many organizations have their standards enacted into law.
|
Authoritative |
|
|
What type of OEEL should be selected to determine environmental exposure acceptability for deployed military personal? |
Military Exposure Guidelines (MEGs). |
|
|
Which of the following OEELs is most appropriate forassessing exposure acceptability for emergency responders? |
PAC –OEELs for emergency responders. |
|
|
What type of sampling method is used to measureexposure over a period of time? |
integrated
|
|
|
True or False? Area samples are not used to establish an exposure for a particular worker. |
true |
|
|
What sampling method would be effective for assessingcadmium contamination on shop table surfaces? |
swipe sampling |
|
|
Under what circumstance is itappropriate to selectively sample the worker with maximum exposure risk? |
compliance sampling |
|
|
What are two main purposes for using the DQO processfor environmental sampling? |
It ensures that the type, quantity, and quality of data collected are appropriate for thedecision at hand. It eliminates the collection of unnecessary, redundant, and overly precise data. |
|
|
How does an OEHSA conceptual site model (CSM) assistwith sampling strategy development? |
The CSM provides data inputs for the DQO process, including the “who, what, where,”etc. for the sampling strategy. |
|
|
What is the difference between QA and QC?
|
Quality Assurance (QA) - generally refers to a broad plan for maintaining quality inall aspects of a program. Quality Control (QC) - consists of the steps you willtake to determine the validity of specific sampling and analytical procedures. |
|
|
When is Chainof Custody documentation required?
|
is required when samples are collected as evidence in the event a crime was committed. |
