F80 Hazard Identification and Risk Assessment 4

Question 1

What is the main difference between a hazard and a risk?

Accepted Answer

A hazard is a potential source of harm; a risk is the likelihood and consequence of that harm occurring

Answer

A hazard is the source or situation with potential to cause harm, while risk combines the probability of harm occurring with its severity.

Question 2

Which of the following control methods is an example of an engineering control?

Accepted Answer

Installing machine guards to prevent contact with moving parts

Answer

Engineering controls physically modify the work environment or equipment to reduce or eliminate exposure to hazards at the source.

Question 3

What is 'quantitative risk assessment' (QRA)?

Accepted Answer

A numerical approach that assigns probability and consequence values to estimate risk magnitude

Answer

QRA uses numerical data and statistical methods to calculate the probability and magnitude of risks, providing a more precise risk estimate.

Question 4

Under OSHA's Hazard Communication Standard (HazCom 2012), the Globally Harmonized System (GHS) requires that labels include:

Accepted Answer

Signal word, hazard statements, pictograms, and precautionary statements

Answer

GHS-aligned labels must include signal words (Danger/Warning), hazard statements, precautionary statements, and standardized pictograms.

Question 5

Which of the following scenarios best illustrates the concept of 'acceptable risk'?

Accepted Answer

Management decides residual risk after controls is low enough that no additional action is required

Answer

Acceptable risk is the level of residual risk that an organization determines is tolerable given the controls in place and the nature of the work.
