• Health effects that develop rapidly

• Health effects that develop slowly

Multiple Choice

On the previous slide there were 7 clues to a haz-mat, they must be labeled exactly as I have typed them 1-7. Why must they remain in order

• Because that is how it is in the book

• The risk increases as the numbers go up.

• Higher numbers indicate the clue will be more difficult to detect

• Both B and C
