Across
- 1. the minimum amount of energy required to ignite a combustible vapor, gas, or dust cloud.
- 3. Recommended exposure limits published by the American Conference of Governmental Industrial Hygienists. These limits may include 8-hour TWA, (C), or STELs.
- 6. Compounds consisting of carbon and hydrogen atoms. Common examples are diesel fuel, JP-5, Cosmoline and lube oil.
- 7. 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.
- 9. the instantaneous concentration that employees shall not be exposed to during any part of the workday.
- 10. 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. Removal of air from a general area, space, room, or building to dilute contaminated air with uncontaminated air.
- 12. The maximum concentration 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.
- 13. The lowest temperature at which the vapors of a material will ignite when an ignition source is provided.
- 15. A space that is affected by work inside the space you are in.
- 20. is defined as the using up of a resource. Where a low oxygen environment oxygen deficiency may develop.
- 22. A condition is one that poses a threat of exposure to airborne contaminants that is likely to cause death or immediate or delayed permanent adverse health effects or prevent escape from such an environment.
- 23. Spaces that are of such a shape, depth, or other feature that natural ventilation or air movement is restricted.
- 25. Oversee the PSNS & IMF Naval Maritime Confined Space Program and to provide technical advice concerning Gas Free Engineering.
- 31. OSHA mandated maximum concentration of toxic material to which most employees may be exposed for an 8-hour day, 40-hour workweek, with no adverse effects.
- 32. A phase change of a material where the material goes from a solid to a gas without going through its liquid state.
Down
- 2. Personnel who have completed formal and on-the-job training, and have been certified by the GFE.
- 4. limits for chemical contaminants adopted by the Navy.
- 5. The lowest temperature at which a material will spontaneously ignite, without an external source of ignition.
- 8. Compounds consisting of carbon, hydrogen, and halogen atoms.
- 14. the range of concentration of a material that will burn or explode if ignited, which is expressed in percent by volume.
- 16. Air exhausting from a specific point designed to capture the contaminant at the source.
- 17. 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.
- 18. 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.
- 19. This term is used to describe the transition of material to different states of matter dependent on temperature and pressure.
- 21. refers to the act of a substance pushing a fluid out of the way and taking its place.
- 24. Refers to processes that do not involve heating 400°F or greater, fire, spark-producing operations, use of hazardous material, or painting.
- 26. 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.
- 27. A confined space that has contained fuels such as JP-5, gasoline, diesel fuel, or fuel oil.
- 28. This means the material can be condensed to a liquid by an increase in pressure without changing the temperature.
- 29. A pipe that has contained JP-5, gasoline, diesel fuel, or fuel oil.
- 30. 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.
