HAZMAT Tech Part IIB
DoD HAZMAT Tech Part II (PPE - E1/E8)
Question | Answer |
---|---|
Level A equipment has been tested with 21 chemicals for this period of time. | 3 Hours |
This NFPA Standard is associated with vapor protection and Level A equipment. | NFPA 1991 |
OSHA requires this Level of PPE when working with an unknown. | Level B (Page 137) |
Level B equipment has been tested with 7 chemicals for this period of time. | 1 Hour |
This NFPA Standard is associated with liquid splash protection and Level B equipment. | NFPA 1992. |
Level C equipment uses this kind of respiratory protection. | Air-Purifying Respirators (APR) |
These levels of PPE can be utilized in an oxygen deficient environment. | Level A and Level B. |
MOPP Gear or daily work clothing are both considered this level of protection. | Level D. |
Fire entry suits, proximity suits, and undergarments are PPE for this hazard. | Thermal. |
Lead aprons are PPE used for this hazard type. | Radiological. |
These levels of PPE provide protection from asphyxiating hazards. | Levels A, B, C |
Etiological/biological hazards typically require this level of PPE. | Level C |
Situations when no information is available to judge whether PPE will provide adequate protection are: | Chemicals not been tested with garments. Mixtures of two or more chemicals. Chemicals that cannot be identified. Extreme environmental conditions. Lack of data on clothing components. |
SCBA provides this amount (time period) of air. | 30 to 60 minutes. |
A SAR air-line supply hose restricts users to this travel distance. | 300 feet. |
Five considerations for selecting the proper respiratory protection. | Name of chemical. Concentration. Hazard. Expected Exposure. OSHA Requirements. |
Eight selection factors for selecting the proper chemical-protective clothing. | Overall suit integrity. Materials chemical resistance. Materials physical properties. Design features. Service life. Potential for exposure. Known Hazards. Cost. |
This term is an increased likelihood that a hazardous material will permeate and penetrate the garments, thus endangering the health of the responder. | Degradation |
The weakening of material, by exposure to chemicals. | Chemical (degradation) |
The weakening or destruction of a material, caused by rubbing against rough surfaces, or leaning/brushing against sharp objects. | Physcial (degradation) |
Indications of material degradation | 1. Stiffness or excess pliability 2. Tears, cuts or abrasions. 3. Damage to zippers or closures. 4.Soft, sticky areas. |
The movement of a chemical through the suit’s closures, cracks, or tears | Penetration |
The process by which a hazardous material moves through a given material on the molecular level, exposing the responder to contamination | Permeation |
NFPA 1991 covers this standard. | Standard on Vapor-Protective Suits |
NFPA 1992 covers this standard. | Standard on Liquid Splash-Protective Suits |
NFPA 1994 covers this standard. | Standard on Protective Ensembles |
This “type” of protection is fully encapsulating, airtight vapor-protective suit with SCBA worn on the inside. | Type 1 |
This “type” of protection is a nonencapsulation suit with SCBA worn on the outside. | Type 2 |
This “type” of protection is a supplied air respirator with encapsulation suits | Type 3 |
This type of heat exchange unit has the following advantages and disadvantages. Advantage: Cools the entire body. Disadvantage: requires an air line and large quantities of breathable air. | Air Cooled |
This type of heat exchange unit has the following advantages and disadvantages. Adv: Relatively inexpensive and lightweight, improve worker comfort, decrease lens fogging. Dis: The coolant packs add additional bulk and weight to the responder’s equipment | Ice Cooled |
This type of heat exchange unit has the following advantages and disadvantages. Adv: Most effective method for controlling body core temperatures. This technology can also be used as a warming system in cold conditions. Dis: Adds both weight and bulk and | Water Cooled |
This type of heat exchange unit has the following advantages and disadvantages. Adv: creates a constant temperature vest and works in harmony with the body. Dis: Cost and requires an ice water or a refrigeration unit to cool the vests. | Phase change cooling technology |
These four process are used in selecting protective clothing. | 1. Criteria established by EPA and OSHA. 2. The Chemical Protective Clothing must be compatible with the chemicals to which it will be exposed. 3. Breakthrough time. 4. Manufactures’ recommendations |
The eight physiological and psychological stress that can affect users of PPE | 1. Low dexterity and mobility. 2. Low visibility. 3. Communication problems. 4. Physical Stress. 5. Claustrophobia 6. Limited dexterity. 7. Heat stress and heat exhaustion. 8. Practice wearing PPE can reduce anxiety |
1. Heat stress is caused by the inability of the body to transfer heat to the atmosphere at a rate equal to, or faster than, it is being generated. 2. Working in a level of PPE that partially or fully blocks the body/s radiated heat from escaping into the | general heat stress symptoms |
1. Cramps in the extremities or abdomen caused by the imbalance of chemicals in the body, as a result of excessive sweating. 2. Symptoms: muscle cramps, weakness, heavy presperation | heat cramps |
Caused by the loss of body fluids through sweating without adequate fluid replacement. Symptoms: Excessive sweating and pale, moist, cool skin. | heat exhaustion |
Exposed to high temperatures which causes the body temperature to rise. It occurs more rapidly in individuals who are engaged in work or other physical activity. It is caused by a failure of the obdy’s cooling mechanism. Symptoms: hot, dry red skin and ra | Heatsroke |
