Chapter 11

1. Immediately dangerous to life or health (IDLH) describes:

2. Why should responders frequently replace oxygen sensors?

3. At WMD or criminal incidents, in order for any recordings to be later admissible as evidence, responders must follow appropriate protocols with regard to:

4. Although they provide more precise readings than pH paper, pH meters may be less practical for field use because:

5. In a colorimetric indicator tube, a preconditioning filter may precede the indicating chemical in order to:

6. Rather than providing concentrations of specific materials, some meters will instead provide the percentage of a:

7. In order to properly determine concentrations of different gases, monitoring and detection equipment should be operated:

8. To verify monitoring and sampling results, when possible, use:

9. Where is it particularly important for responders to test for the presence of radiation and contamination?

10. Why might it be helpful to contact current users of equipment before you buy it?

11. Exposure limit is the:

12. A typical 4-gas monitor will detect:

13. When responders use a CGI calibrated to one gas to measure other flammable gases:

14. Lethal concentration is the concentration of an _____ substance that results in the death of the entire test population.

15. Why should responders monitor oxygen levels when using combustible gas indicators (CGis)?

16. While no current meter or device can detect reactive materials, potentially hazardous chemical reactions will cause:

17. A pH of 7 is:

18. Roentgen® is a unit used to measure:

19. Two key factors that dictate the detection and monitoring strategies and tactics used at an incident as well as the PPE required to perform these strategies and tactics are the hazards present at the incident and the:

20. Stripped or bleached pH paper likely indicates:
