What is the purpose of CHART?
To significantly increase the commander's decision making capability in a CBRN environment
What is the M272's shelf life?
5 years
What can produce minus errors?
Water aerosols
About how many entries are in the chemical library?
10,000
What is the pH range of a strong alkaline?
pH 12 - pH 14
What are the three types of risk that CHART assesses?
CWA, Radiological, Biological Agents
What does the M272 detect?
Nerve, VX, Lewisite, Cyanide, Mustard in water
What range of temps dos the CDS kit operate at?
41-86 Fahrenheit
What are the proper full decon procedures, if any, for the Hazmat ID Elite?
1. Ensure the external power is unplugged and battery compartment sealed
2. Immerse fully in a 0.5% bleach solution
Why is it important to identify pH of a substance?
Equipment limitations, identification of substances, and PPE recommendations
What is baseline risk? Residual risk?
Baseline - LOD capability of specific piece of equipment
Residual - Remaining risk after concentration falls below LOD
What does the M256 detect?
Blood, blister (lewisite and mustard), nerve agents in air
What state must chemicals be in to be detected?
Vapor, Aerosol
What types of bonds does the Hazmat ID Elite not detect? What is an example?
Ionic bonds;
When a substance is dissolved in water the solution has more hydrogen ions than hydroxide ions what kind of solution is it?
Acidic Solution
In CHART, what level of protection is associated with inhalation/ocular exposure? Percutaneous?
unprotected, no mask, no MOPP; mask only
Besides the M256, what else is found in the M256A2 kit?
M8 paper & M9 tape
Name all agents that the CDS kit tests for.
Nerve, Blister, Lung, blood agents
What technology does the HAZMAT ID use?
Bonus: How does it work?
FTIR (Fourier Transform Infrared Spectroscopy)
Bonds between different elements absorb light at different frequencies. FTIR measures the absorbance of light waves at various wavelengths to determine the materials composition.
How must pH paper be prepared, if at all, to monitor vapors or gases in air?
Who was Haber? What is Haber's law?
Haber - WWI-era chemist, "Father of Chemical Warfare", synthesized ammonia from nitrogen in air
Haber's law - C * T = Toxicological Effect; relationship between concentration of a poisonous gas and how long the gas must be breathed to produce a toxicological effect
