Q: In the GHS, what are the number of classes of physical, health, and environmental hazards, respectively?
- 1, 11, 16
- 1, 16, 11
- 11, 16, 1
- 16, 11, 1
A: 16, 11, 1

Q: For which category of health hazard do we have relatively good data for many chemicals?
- Germ cell mutagenicity
- Eye damage and eye irritation
- Skin corrosion
- Acute toxicity
A: Acute toxicity

Q: For the class of acute toxicity, the signal word "Danger" is used for what hazard categories?
- 1
- 1, 2
- 1, 2, 3
- 1, 2, 3, 4
A: 1, 2, 3

Q: What range of LD_50 values is considered "fatal if swallowed"?
- =<5mg/kg
- =<50mg/kg
- =<300mg/kg
- =<500mg/kg
A: =<50mg/kg

Q: What range of LC_50 values is considered "fatal if inhaled" for gases?
- =<100ppm
- =<500ppm
- =<5000ppm
- 500>=<5000ppm
A: =<500ppm

Q: Select the main routes (all that apply) of exposure considered when assessing acute toxicity.
- Oral
- Dermal
- Inhalation
- Ingestion
A: Oral; Dermal; Inhalation

Q: What is the difference between 'acute' and 'chronic'?
- Acute means a sudden onset; chronic takes a long time
- Acute is not as bad as chronic
- Acute is always fatal; chronic doesn't have to be
- Acute is never seen in a lab setting; chronic usually is
A: Acute means a sudden onset; chronic takes a long time

Q: Where does the data for acute toxicity classification come principally from?
- Animal testing
- Actual human exposures in workplaces
- Unintentional and intentional poisonings
- Anecdotes
A: Animal testing
