DIOXIDE DISPENSERS) EXAM PRACTICE
QUESTIONS AND CORRECT ANSWERS

1. What is the primary hazard associated with carbon dioxide (CO₂)
in confined spaces? A. Flammability
B. Asphyxiation
C. Explosivity
D. Corrosivity
Rationale: CO₂ is non-flammable and non-corrosive, but it can displace oxygen in
confined spaces, creating an asphyxiation hazard.
2. What is the typical color code for a carbon dioxide cylinder in the United
States?
,A. Red
B. Blue
C. Gray
D. Green
Rationale: According to CGA and NFPA standards, carbon dioxide cylinders
are typically gray to distinguish them from other gases.
3. When transporting CO₂ cylinders, they must always be:
A. Laid on their side
B. Secured in an upright position
C. Carried by one hand
D. Stored in a refrigerator
Rationale: Cylinders must be transported upright to prevent valve damage and
ensure safe handling.
4. Which of the following personal protective equipment (PPE) is
recommended when dispensing CO₂?
A. Flame-resistant clothing
B. Gloves and safety goggles
C. Rubber boots only
D. Hearing protection
Rationale: Gloves protect against cold burns, and goggles protect eyes from CO₂
splashes or frost.

5. What is the safe maximum fill pressure for a typical CO₂ beverage
cylinder?
A. 100 psi
B. 400 psi
C. 850 psi
D. 1200 psi
Rationale: Standard beverage-grade CO₂ cylinders are typically filled to a
maximum of about 850 psi at room temperature.
6. What should be done if a CO₂ cylinder shows signs of rust or damage?
A. Use it carefully
B. Remove it from service and tag it as defective
C. Paint over the rust
D. Store it outside
Rationale: Damaged or corroded cylinders can fail under pressure and must not
be used.
7. How should CO₂ cylinders be stored?
, A. In a warm room
B. In a well-ventilated, cool area away from heat sources
C. Near open flames
D. In a sealed, airtight cabinet
Rationale: CO₂ should be stored in a ventilated area to prevent oxygen
displacement and maintain cylinder integrity.
8. When connecting a CO₂ regulator to a cylinder, the first step is to:
A. Open the cylinder fully
B. Check the regulator and connections for damage
C. Shake the cylinder
D. Remove the safety cap
Rationale: Inspecting equipment ensures no leaks or malfunctions before
pressurizing the system.
9. What is a common symptom of CO₂ exposure at elevated
concentrations?
A. Burns
B. Dizziness and shortness of breath
C. Rash
D. Hearing loss
Rationale: High concentrations of CO₂ reduce available oxygen, leading to
dizziness, headache, and possible loss of consciousness.
