coverage.
b) Flammability -
CGI, Multi-Gas Monitor, PID, FID - ✔✔-- Used to determine the presence of flammable vapors of
hydrocarbon products
- They measure the flammable vapors as a percentage of the lower explosive limit
- Many combustible gas indicators are combination instruments, that also measure oxygen content and
several toxic substances
(c) Oxidation potential -
Oxygen Meters and Photoionization Detectors - ✔✔-- Measure of a substances ability to oxidize, its
propensity to yield oxygen
- The more readily a material gives up its oxygen molecule, the greater the hazard it presents.
(d) Oxygen deficiency -
Oxygen Meters and Photoionization Detectors - ✔✔-- Measures oxygen concentrations over a range of 0
to 25 percent oxygen in airbelow
- 19.5 percent is the minimum permissible percentage of oxygen as established by (OSHA)
- Below this level, the responder must have a supplied-air respirator
(e) Corrosively pH -
Litmus dye, pH paper, pH Meters - ✔✔-- Corrosively is measured by determining the pH of a material
, - Done using pH paper or pH meters. On pH paper the color changes, indicating the pH level
(f) Toxic levels (Toxicity) -
Photoionization Detectors, Flame ionization Detector, Infrared Spectrophotometers and Detector tubes
- ✔✔-- Some instruments measure specific chemicals, such as hydrogen sulfide, and some may measure
more than one chemical
- Detector tubes operate by drawing an air sample through a small glass tube
(g) Pathogenicity -
Biological Immunoassay Indicators, DNA Fluoroscopy, Polymerase Chain Reaction (PCR) and Hand Held
assays - ✔✔-- Pathogenicity is the virulence of a pathogen. Virulence refers to how ill an individual may
become
- The "GOLD STANDARD" continues to be a laboratory capable of identifying pathogens
- In the U.S. "gold standard" is a CDC certified Laboratory Response Network facility
A10. Identify the capabilities and limiting factors associated with the selection and use of the following
monitoring equipment, test strips, and reagents - ✔✔-(1) Biological immunoassay indicators (Hand held
assays)
