Flashcards in Aviation Toxicology Deck (32):
1

What is an occupational hazard?

Anything capable of producing an adverse health effect

2

2 types of toxic exposure types

Acute and Chronic

3

Acute

short term exposure (such as smoke in the cockpit)

4

Chronic

long-term exposure (such as smoking)

5

Routes of Entry Principle for Toxins

Inhalation Absorption Ingestion

6

Inhalation

toxins enter throgh the lungs

7

Absorption

toxins enter through the skin

8

Ingestion

toxins enter through the mouth

9

In the aviation environment which route of entry is considerd the most improtant

Inhalation

10

Excretion

How quickly the body gets rid of toxins

11

Retention

How long a toxin stays in body

12

Which organs are responsible for filtering out and excreting toxins

The liver and kidneys

13

Physiological Principles regarding effects of toxins

Determined by individual's: Metabolism, Body Composition, and Genetics

14

What are some Aviation toxic substances

Aviation Fuels, Aviation Fuel Combustion, Solvents/Degreasers, Lubricants, Hydraulic Fluids, Fire Extinguishers, Composites/Plastics.

15

What is the most primary concern regarding toxins from JP fuels

Inhalation of fumes/vapors

16

What is the most common and toxic substance in the aviation environment

Carbon Monoxide

17

What are some of the effects of CO intoxication?

Headache, weakness, dizziness, nausea, confusion, and loss of consciousness.

18

What is the easiest way to remember the effects of carbon monoxide exposure

early symptoms look like the flu

19

What is the source of carbon monoxide

byproduct of incomplete combustion -- e.g. exhaust

20

What is a primary concern regarding hydraulic fluids

Fluids are maintained under high pressures, inhalation of aerosolized particles

21

What is the principle hazard of composites

inhalation of microscopic fibers/particles that embed in the lungs and cause an asbestos like reaction

22

What is the primary hazard of plastics

Burning of plastics releases Cyanide, Phosgene, and Flourine

23

_________ is anything capable of producing an adverse health effect on a worker.

Occupational hazard

24

__________ is a long term exposure to an agent or a series of repeated exposures to an agent that lead to adverse health effects.

Chronic exposure

25

_________ Is exposure of an agent over a short period of time that can cause adverse health changes

Acure exposure

26

How long a toxin is kept in the body is __________.

the rate of retention

27

_________ is the term for how quickly the body rids itself of the toxin.

excretion

28

An odorless, tasteless, and colorless vapor produced by the incomplete combustion of fuel.

Carbon Monoxide (CO)

29

Three physiological principles that determine a response to a toxin are?

  • Metabolism
  • Body composition
  • Genetics

30

True or false: Plastics release no harmful chemicals when burned.

False

31

True or false: The primary hazard with fibers is absorption.

False. Inhalation is!

32

The effects of a toxin on the body depend on the ________, and ________ of exposure.

duration, route
