F80 Hazard Identification and Risk Assessment 5

Question 1

Which type of risk assessment method uses descriptive categories such as 'low,' 'medium,' and 'high' rather than numerical values?

Accepted Answer

Qualitative risk assessment

Answer

Qualitative risk assessments use descriptive categories and relative rankings rather than precise numerical probabilities or consequence values.

Question 2

An employer is reviewing a new chemical process. Which hazard identification technique involves systematically applying guide words such as 'no flow' or 'reverse flow' to identify deviations?

Accepted Answer

Hazard and Operability Study (HAZOP)

Answer

HAZOP uses structured guide words applied to process parameters to systematically identify ways a process can deviate from its intended design.

Question 3

Which of the following is a psychosocial hazard in the workplace?

Accepted Answer

Excessive workload leading to chronic workplace stress

Answer

Psychosocial hazards arise from the design, organization, and management of work and can cause psychological harm such as stress, burnout, or anxiety.

Question 4

A 'bow-tie analysis' in risk assessment is best described as:

Accepted Answer

A diagram showing both the causes of a hazardous event and its consequences, with controls on each side

Answer

Bow-tie analysis combines a fault tree (causes/threats on the left) with an event tree (consequences on the right), placing the hazardous event at the center with controls visualized on each side.

Question 5

When assessing radiation hazards, which type of ionizing radiation has the greatest penetrating power?

Accepted Answer

Gamma rays

Answer

Gamma rays are electromagnetic radiation with very high penetrating power, capable of passing through the human body and requiring dense shielding like lead or thick concrete.
