- 2. The minimum amount of energy required to ignite a combustible vapor, gas, or dust cloud.
- 4. This term is used to describe the transition of material to different states of matter. The transition between these states of matter is dependent on temperature and pressure.
- 5. Spaces that are of such a shape, depth, or other feature that natural ventilation or air movement is restricted.
- 8. Process involving open flame, electric arc, heating of metal to 400°F, or to a temperature where adjacent materials could ignite or be damaged.
- 11. The range of concentration of a material that will burn or explode if ignited, which is expressed in percent by volume.
- 13. Oversee the PSNS & IMF Naval Maritime Confined Space Program and to provide technical advice concerning Gas Free Engineering.
- 16. Air exhausting from a specific point, near the contaminant, designed to capture the contaminant and prevent its dispersal.
- 18. A space that is affected by work inside the space you are in.
- 20. The act of a substance pushing a fluid out of the way and taking its place.
- 22. The lowest temperature at which the vapors of a material will ignite when an ignition source is provided.
- 24. Refers to processes that do not involve heating 400°F or greater, fire, spark-producing operations, use of hazardous material, or painting.
- 25. A condition is one that poses a threat of exposure to airborne contaminants when that exposure is likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment.
- 26. A state of matter, where the material has no fixed volume. Will take the shape of the container and achieve a uniform density inside the container regardless of the amount of substance inside the container.
- 28. A confined space that has contained fuels such as JP-5, gasoline, diesel fuel, or fuel oil.
- 29. A pipe that has contained JP-5, gasoline, diesel fuel, or fuel oil.
- 30. Performed anytime an individual enters a confined space. Access to the space is considered to have occurred as soon as any part of the entrant’s body breaks the plane of an opening into the space.
- 31. Limits for chemical contaminants adopted by the Navy.
Down
- 1. A space large enough and so configured that a worker may enter to work and that: Has limited or restricted means of entry or exit. Lacks natural ventilation. May contain or produce contaminants or have an oxygen deficient or enriched environment. It is not intended for continuous personnel occupancy.
- 3. A material in the gas phase at a temperature lower than its critical temperature. This means the material can be condensed to a liquid by an increase in pressure without changing the temperature.
- 6. A state of matter, where the material is resistant to changes in shape or volume. A material that does not flow to take the shape of its container like a liquid and does not expand to take the shape of its container.
- 7. The maximum concentration (expressed as a 15-minute TWA) that employees shall not be exceeded during any part of the workday. Exposures above 8 hr. TWA up to time should be less than 15 minutes and should occur no more than four times per day.
- 8. Compounds consisting of carbon, hydrogen, and halogen atoms.
- 9. Compounds consisting of carbon and hydrogen atoms. Common examples are diesel fuel, JP-5, Cosmoline and lube oil.
- 10. The instantaneous concentration that employees shall not be exposed to during any part of the workday.
- 12. OSHA mandated maximum concentration of toxic material (expressed as an 8-hour Time-Weighted Average (TWA)) to which most employees may be exposed for an 8-hour day, 40-hour workweek, with no adverse effects.
- 14. Using up of a resource.
- 15. Recommended exposure limits published by the American Conference of Governmental Industrial Hygienists. These limits may include 8-hour TWA, (C), or STELs.
- 17. The lowest temperature at which a material will spontaneously ignite without an external source of ignition.
- 19. A phase change of a material, where the material goes from a solid to a gas without going through its liquid state.
- 21. Personnel who have completed formal and on-the-job training and have been certified by the GFE.
- 23. A state of matter, where the material remains at constant volume independent of pressure but can flow freely to take the shape of a container.
- 27. Exhaust Ventilation Removal of air from a general area, space, room, or building to dilute contaminated air with uncontaminated air.
