COSC 464 - EXAM #1 - HAZARDS/FIRES - QUESTIONS AND ANSWERS | WITH COMPLETE
SOLUTIONS.
Question 1
How many standardized sections are required to be on a Safety Data Sheet (SDS) under the
Globally Harmonized System (GHS)?
A) 8
B) 10
C) 12
D) 16
E) 20
Correct Answer: D) 16
Rationale: OSHA mandates that all Safety Data Sheets follow a strict 16-section format to
ensure that information is consistent, easy to find, and covers all necessary aspects of
chemical safety, from identification to disposal.
Question 2
According to the COSC 464 curriculum, which group of SDS sections is most frequently
discussed and utilized in the field?
A) Sections 1, 2, 3, 4
B) Sections 2, 4, 7, 8
C) Sections 9, 10, 11, 12
D) Sections 13, 14, 15, 16
E) Sections 5, 6, 7, 8
Correct Answer: B) Sections 2, 4, 7, 8
Rationale: These sections contain the most critical immediate information: Hazard
Identification (2), First Aid Measures (4), Handling and Storage (7), and Exposure
Control/Personal Protection (8).
Question 3
Which section of the SDS provides a general "Hazard Identification," including classification
and required labeling?
A) Section 1
B) Section 2
C) Section 4
D) Section 8
E) Section 10
Correct Answer: B) Section 2
Rationale: Section 2 is essential because it lists the classification of the substance, required
pictograms, signal words (Danger/Warning), and the NFPA 704 rating, which helps
workers identify risks at a glance.
Question 4
A worker needs to know the correct "First Aid Measures" after being exposed to a chemical.
, Page 2
Which SDS section should they consult?
A) Section 2
B) Section 3
C) Section 4
D) Section 7
E) Section 9
Correct Answer: C) Section 4
Rationale: Section 4 outlines necessary first aid instructions by route of exposure
(inhalation, skin contact, etc.) and provides information on immediate medical attention
and special treatment needed.
Question 5
Where would you find information regarding the specific temperature and environment required
for "Handling and Storage" of a hazardous material?
A) Section 4
B) Section 5
C) Section 7
D) Section 8
E) Section 11
Correct Answer: C) Section 7
Rationale: Section 7 details safe handling practices and conditions for safe storage,
including incompatibilities with other chemicals and specific environmental requirements
to prevent accidents.
Question 6
Which section of the SDS identifies "Exposure Control" and specifies the necessary "Personal
Protection" (PPE) required for a task?
A) Section 2
B) Section 4
C) Section 7
D) Section 8
E) Section 16
Correct Answer: D) Section 8
Rationale: Section 8 is vital for worker safety as it lists exposure limits, engineering controls,
and the specific types of PPE (gloves, respirators, etc.) required to prevent overexposure.
Question 7
GHS pictograms are primarily divided into which two broad categories?
A) Reactive and Non-reactive
B) Internal and External
C) Physical Hazards and Health Hazards
D) Solids and Liquids
, Page 3
E) Warning and Danger
Correct Answer: C) Physical Hazards and Health Hazards
Rationale: Pictograms are grouped based on whether they represent physical threats (like
flammability or explosion) or health threats (like toxicity or carcinogenicity).
Question 8
Which pictogram is represented by a "Circle with a flame"?
A) Flammable
B) Explosive
C) Oxidizer
D) Corrosive
E) Compressed Gas
Correct Answer: C) Oxidizer
Rationale: The "O" for Oxygen (the circle) with a flame indicates an oxidizer, which is a
substance that can provide oxygen to a fire, making it burn more intensely.
Question 9
How does the "Flammable" pictogram differ from the "Oxidizer" pictogram?
A) It includes a skull
B) It features a flame only, without a circle
C) It has an exclamation mark
D) It shows a bomb exploding
E) It is blue instead of red
Correct Answer: B) It features a flame only, without a circle
Rationale: The "Flame" pictogram alone indicates that the substance itself is flammable or
self-reactive. The addition of the circle (as seen in Oxidizers) signifies the presence of
oxygen-contributing properties.
Question 10
Which physical hazard pictogram depicts an "Exploding Bomb"?
A) Corrosion
B) High Pressure
C) Explosion
D) Oxidizer
E) Flammable
Correct Answer: C) Explosion
Rationale: The exploding bomb symbol represents explosives, self-reactive substances, or
organic peroxides that can cause a sudden release of energy.
Question 11
The pictogram showing "Corrosive on metal and a hand" represents what type of hazard?
A) Only Physical Hazards
SOLUTIONS.
