Sampling Strategies
The ______ ______ is categorized by rankings of negligible, marginal, critical, and catastrophic.
Hazard severity
I am a quick and easy tool for shallow subsurface samples but not recommended for VOCs.
Auger
I contain multi-threat gas detectors that combine continuous monitoring capabilities for VOCs, toxic and combustible gases, and radiation. My probe can be inserted into a jar or bag of soil to determine potential off-gassing.
MultiRAE
To prevent cross-contamination, you must ______ equipment between sampling sites.
Decontaminate
All soil is dirt but not all dirt is...
Soil
This is where we consolidate all complete and potentially complete exposure pathways to include the pathway elements, existing controls and frequency of exposure.
Conceptual Site Model (CSM)
Recommended for powdered or granular materials in piles or in bags, drums, or similar containers. Best for moist or sticky materials.
Trier
I verify the presence/absence of chemical compounds in solid or liquid samples. I am not intrinsically safe and will not identify gases, vapors, or radiation, or any compounds that are dangerous to life and/or health.
HazMatID Elite
Contains occupational and environmental health risk data and tracks hazard exposures for DoD service members. After soil sampling has been conducted you must input your results here.
DOEHRS
I am commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and other organisms.
Soil
A consolidation of individual exposure pathways sampling strategies, with the objective being to obtain sampling data to characterize OEH risks.
Sampling and Analysis Plan (SAP)
One of the most effective samplers for general use on all types of substrates. It may be difficult to repeatedly collect representative samples and it may be heavy.
Ponar dredge
I combine two analytical techniques, gas chromatography and mass spectrometry to separate and identify the organic components in a gas phase sample. I can be used to identify and quantify VOCs in soil.
Hapsite ER
I am a chemical concentration that represents a safe-sided estimate of the level above which certain types of health effects may begin to occur in individuals after an exposure of the specified duration.
Military exposure guidelines (MEGs)
I am a substance that is fine-grained and composed of very small particles.
A ________ sampling design is to be used during a worst-case scenario with direct reading instruments to the closest point to the source in the exposure point area.
Judgmental
May be driven manually or mechanically by a drill rig with trained personnel. It may collect a sample at depth and a liner can be used to minimize disturbance or for samples requiring VOC analysis.
Split barrel sampler
I heat the sample to allow compounds to volatize. A sample must be collected into a 40mL vial and placed into a sample well of the heater block, after which a portion is drawn through the top of the needle and transferred to the HAPSITE.
Headspace Sampling System (HSS)
Soil MEGs were developed assuming continuous exposure for how long?
1 year
I am a slimy sticky mixture of solid material with a liquid, especially water.
Mud
The DOD has adopted a modified version of the AIHA exposure assessment strategy called the ___ ___ ___ ___ ___ to conform to the military decision-making process and incorporate language specific to DOD systems.
DOD IH Exposure Assessment Model
To execute soil sampling during deployments, BE may request an _____ _____ _____, which consists of a brown pouch, Teflon jars, datasheets, nitrile gloves, ice packs, and a cooler.
APHC Sampling Kit
Use me to screen for metals in soil.
XRF
The MEGs are _____ _____ guidelines and are not specifically designed for generating casualty estimates.
Preventative medicine
I am an unclean matter, especially when in contact with a person's clothes, skin, or possessions.
Dirt
