Organic Chemistry Safety Quiz
Sustainability means meeting the needs of the present - correct answer-Without
compromising the ability of future generations to meet their own needs
Which solvent is the greenest?
(a) Hydrocarbon with halogens
(b) Perhalogenated hydrocarbon
(c) Supercritical carbon dioxide
(d) Solvent with very high boiling point - correct answer-(c) Supercritical carbon dioxide
Using catalysts in reactions is a green step because - correct answer-Catalysts allow
reactions to be run under less energy intensive conditions
What are the green features of a chemical synthesis?
(a) High yield, approaching 100%
(b) Use of less-toxic reagents
(c) Production of less-toxic by-products
(d) All of the above - correct answer-(d) all of the above
The green chemistry goal of designing chemicals with "little or no toxicity" is a challenge
because
(a) All chemicals are toxic at a high enough dose
(b) TCSA does not require chemical companies to assess toxicity, therefore we know little
about the toxicity of many chemicals
(c) The "least toxic" chemicals are already being used and produced by chemical
manufacturers
(d) Both (a) and (b) - correct answer-(d) both (a) and (b)
Most of the fires that one would expect to encounter in an organic synthesis lab would be
(For additional information, there is a description of Classes on Table 2.1.2.1 on page 2-73.)
- correct answer-Class B
Although rarely encountered in academic environments, some industrial labs may have
whole-room, automated suppression systems. These systems use CO2 or some inert gas
and are designed mostly for - correct answer-Class C fires
Active metal fires
(a) Should not be extinguished using water
(b) Are usually associated with strong reducing agents
(c) Should be extinguished only with a Class D extinguishing agent
(d) All of the Above - correct answer-(d) all of the above
The portable fire extinguisher of most use in an organic lab will be - correct answer-BC
SDSs are required by - correct answer-The OSHA Hazard Communication Standard
, Which statement is true?
a) It is required that old OSHA MSDSs and new GHS SDSs to follow the ANSI format.
b) It is recommended that old OSHA MSDSs and new GHS SDSs to follow the ANSI format.
c) It is required that old OSHA MSDSs follow the ANSI format but only recommended that
new GHS SDSs to follow the ANSI format.

new GHS SDSs follow the ANSI format. - correct answer-d) It is recommended that old
OSHA MSDSs follow the ANSI format but it is required that new GHS SDSs follow the ANSI
format.

correct answer-11%
