3. Exposure limit is the:

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

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

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

7. Roentgen® is a unit used to measure:

8. Why should responders frequently replace oxygen sensors?

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

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

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

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

13. A typical 4-gas monitor will detect:

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

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

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

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

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

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

20. 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:
