Answer 1

25m

Question 2

How far should you initially be away from a hazardous liquid spill?

Answer 2

50m

Question 3

How far should you initially be away from a hazardous gas spill?

Answer 3

100m

Question 4

True or False:

Expanding gasses can displace oxygen, creating an asphyxiating atmosphere?

Answer 4

True

Question 5

What is vapor pressure?

Answer 5

The pressure at which a vapor is in equilibrium with its liquid phase for a given temperature

Liquids that evaporate easier have a higher vapor pressure for a given temp

Question 6

Materials with a vapor pressure of what mmHg will be gasses under normal conditions?

Answer 6

760mmHg

Question 7

BLEVE stands for what?

Answer 7

Boiling Liquid Expanding Vapor Explosive

Question 8

What is a polar solvent?

Answer 8

Liquids that are miscible with other liquids

Question 9

What is persistence?

Answer 9

The length of time time a chemical is able to remain in the environment

Question 10

Difference between flash point and fire point

Answer 10

Flash point is minimum temperature that a liquid/volatile solid gives off sufficient vapors at it’s LEL to form an ignitable mix with air near its surface (won’t keep burning)

Fire point temp when liquid/solid gives off vapors that support continuous burning

Question 11

What is the pH value of a base?

Answer 11

7.1 -14

Question 12

Main difference between acids and bases?

Answer 12

Acids = surface (skin) burn: immediate pain

Bases = fatty tissue burn: delayed pain but worse damage than acid

Question 13

Different kinds of radiation

Answer 13

Alpha
Beta
Gamma
Neutron
