The analysis scheme implemented at the Cos Cob site used three sets of tools hand-held test kits, an on-site mobile laboratory equipped with gas chromatograph/ electron capture detector (GC/ECD) and X-ray fluorescence (XRF), and an off-site laboratory with rapid turnaround capabilities (<48 h for virtually all analyses). By implementing all of these tools at the same time, the project eliminated the need for multiple sampling events and allowed the team to perform additional real-time sampling, enabling the team to delineate the extent of potential hot spots quickly. 

Follow the directions on the radon-testing kits, and expose the detectors in the selected home. If there are a sufficient number of kits for the class, some groups can expose their detectors in upper levels of homes, and other groups can do so in basements. Send the detectors to be evaluated according to the instructions. 

Detection. Automatic detectors are available which detect attack concentrations of vapors of hydrogen cyanide, cyanogen chloride and cyanogen bromide. Draeger tubes are also available, as are water testing kits. 

Keen visual observation is the most important task during a site reconnaissance. Flowever, some basic in-held chemical testing equipment is useful. Commercial kits are available, mainly based on colorimetric reactions. These kits can be used to check for the presence or absence of common contaminants and to measure soil pH. However, the results obtained using these test kits should only be regarded as qualitative, not least because samples taken at the surface may not represent the bulk of materials on the site. For site reconnaissance, the use of in-held instrumental testing is not justihed. An exception is hand-held equipment to test for the presence of gaseous and volatile contamination—photo-ionisation and other detectors are useful where such contaminants are anticipated. While a Phase la study does not normally include intrusive investigation, a small number of samples may be taken for laboratory analysis. These can be important when waste and other potentially contaminated materials of unknown composition have been spread, deposited or are stored on the site. 

Hazardous materials or "Hazmat" teams are routinely equipped with a variety of chemical detectors and monitoring kits, primarily employing chemical-specific tests indicating only the presence or absence of a suspected chemical or class of chemical. The most common detectors test for pesticides, chlorine, and cyanide, but not specifically for phosgene, vesicants, or nerve agents. Although chemical tests, detectors, and monitors used by the military are commercially available for civilian use, they have not been acquired by civilian organizations in appreciable numbers. 

The Chemical Agent Water Test Kit M272 consists of colorimetric detector tubes and enzyme impregnated detection tickets for nerve agent detection. The kit is designed to detect the presence of chemical agents in water samples.

In order to use commercial reagents in a drug development program, it was important to negotiate and plan with the kit supplier to assure consistency of the Ab reagents, and that sufficient quantities would be reserved. Method robustness included the pre-study validation tests with a second lot of the capture Ab, three analysts, and three batches of radioiodinated detector Ab. Method robustness was further demonstrated by in-study validation, with four additional analysts performing sample analysis using 12 batches of radioiodinated detector Ab over a time span of approximately three years.

The most widely available U.S. military detector for chemical agent vapors is the M256A1 Chemical Agent Detector Kit. These kits contain cards with vials of liquid chemical reagents attached that are combined and exposed to the air in a specific sequence. The kits must be manually manipulated, and the full sequence of tests takes 20 to 25 minutes. These kits are the most sensitive detector of nerve agent vapor and are not subject to the same type of interferents that can cause false alarms in some of the electronic detector systems. 

With M256 or M256A1 Detector Kit 1. Test with the detector kit. 

B. Unmasking Procedures with M256 or M256A1 Detector Kit. Test with detector kit. If the test is negative, have one or two soldiers move to a shady area if possible and unmask for 5 minutes. Have the soldiers remask. Observe them for 10 minutes for symptoms. If symptoms do not appear, it is safe to give the all clear signal and unmask. The senior leader present may ask higher headquarters for permission. Continue to observe the soldiers in case delayed symptoms develop.
