Total questions: 10
Worksheet time: 5mins
What are the two main types of pressure vessels?
Portable and Fixed
Liquid and Gas
High and Low Pressure
Fired and Unfired
Which of the following is a characteristic of fired pressure vessels?
They are only used for storage.
They do not use an external heat source.
They are heated by an external source.
They are designed to store gases or liquids under pressure without heat.
What is a key hazard associated with pressure vessels?
Insufficient storage
Low temperature
Lack of maintenance
Overpressure
What can cause thermal stress in pressure vessels?
Poor design
Rapid changes in temperature
Low pressure conditions
Excessive corrosion
What is required for personnel operating pressure vessels?
They must be adequately trained and certified.
They should have a high school diploma.
They must have experience in unrelated fields.
No specific training is needed.
What does the 1970 regulation require for pressure vessels?
They do not require any reporting of incidents.
They can be built without safety standards.
They must be registered and licensed.
They must be operated without any inspections.
Which of the following is NOT a hazard of pressure vessels?
Low humidity
Thermal Stress
Corrosion
Overpressure
What is the purpose of regular inspections of pressure vessels?
To increase the pressure inside the vessels.
To identify and mitigate potential hazards.
To reduce the cost of operation.
To ensure they are used for storage only.
What is a common example of an unfired pressure vessel?
Steam boiler
Burner
Heat exchanger
Storage tank
What is the consequence of overpressure in a pressure vessel?
It can lead to corrosion.
It can cause mechanical failure.
It can result in catastrophic failure or explosion.
It can improve efficiency.
