Chapter 9 Flashcards
______________ is the most significant route of entry for hazardous materials
inhalation
motorized respirator that uses a filter to clean surrounding air, then delivers it to the wearer to breathe
Powered air purifying respirator (PAPR)
OSHA mandatory respiratory standard for the US
OSHA 29 CFR 1910.134
SCBA must meet the design and testing criteria for _____________
NFPA 1981
the use of only __________________ open circuit or closed circuit SCBA is allowed in incidents where personnel are exposed to hazardous materials
positive pressure
2 types of high temperature clothing
proximity suits, fire entry suits
suit permits close approach to fires for rescue, fire suppression and other fire fighting operations involving flammable liquids
proximity suit
allow a person to work in total flame environment for short periods. up to 2000°F
fire entry suit
Fibers that do no support combustion due to their chemical structure
inherently flame resistant (IFR)
chemical compound that can be incorporated into a textile to reduce its flammability. can be washed out
flame retardant
2 types of chemical protective clothing
- liquid splash protection
2. vapor protection
NFPA __________ sets the minimum standard for liquid splash protective clothing
1992
NFPA _________ specifies requirements for a minimum level of protection for response personnel facing exposure to specified chemicals. Total Encapsulating Chemical Protective suits (TECP)
1991
chemical protective clothing’s effectiveness can be reduced by three actions:
- permeation
- degradation
- penetration
process in which a chemical passes through a protective material on a molecular level
permeation
process that occurs when the characteristics of a material are altered through contact with chemical substances
chemical degradation
process in which a hazardous material enters an opening or puncture in a protective material
penetration
highest level of skin, respiratory, and eye protection that can be given by PPE. consists of positive pressure SCBA, totally encapsulating chemical protective suit, inner and outer gloves, and chemical resistant boots
Level A PPE
PPE that provides the highest level of respiratory protection but a lesser level of skin protection. consists of positive pressure SCBA, hooded chemical protective suit, inner and outer gloves, and chemical resistant boots
Level B PPE
PPE that affords a lesser level of respiratory and skin protection. consists of a full face or half face APR, hooded chemical resistant suit, inner and outer gloves and chemical resistant boots
Level C PPE
PPE that affords the lowest level of skin and respiratory protection. consists of coveralls, gloves, and chemical resistant boots or shoes
Level D PPE
heat illness in which the body’s heat regulating mechanism fails; fever of 105° to 106°, dry, red, and hot skin, rapid strong pulse, deep breaths or convulsions
heat stroke
heat illness caused by exposure to excessive heat; weakness, cold and clammy skin, heavy perspiration, rapid and shallow breathing, weak pulse, dizziness, and sometimes unconsciousness.
heat exhaustion
heat illness resulting from prolonged exposure to high temps; excessive sweating, muscle cramps in abdomen and legs, faintness, dizziness, exhaustion
heat cramps
condition that develops from continuous exposure to heat and humid air; aggravated by clothing that rubs the skin. reduces the individual’s tolerance to heat
heat rash
standard on the rehabilitation process for members during emergency operations and training exercises
NFPA 1584
foot condition resulting from prolonged exposure to damp conditions or immersion in water
trench foot
a condition of impurity resulting from contact or mixture with a foreign substance
contamination
a hazardous material has entered or potentially entered your body via the routes of entry
exposure
