Assess risk and explain compliance requirements.

Moving beyond basic PPE, this lesson covers formal risk assessment, incident investigation, and the vocabulary of professional safety management.

Why this matters This lesson connects directly to your progress: it covers risk assessment and hazard control; incident investigation and compliance; safety programs and management systems. Mastering this content lets you move forward confidently, and reinforces patterns you'll use again later. Take time to review every example before moving to the assessment — repetition is what actually locks knowledge in long-term.

Reading

Read the text and answer the questions. You can try as many times as you want.

After the recent incident, the safety team conducted a root cause analysis and identified a gap in the lockout-tagout procedure. "The incident investigation revealed a procedural gap," the safety manager reported to the committee, which meets monthly to review incident reports.

"We need to update our emergency response plan," she added, "and we're implementing a permit-to-work system for high-risk tasks going forward." The team also began tracking leading indicators to prevent future incidents, alongside their total recordable incident rate.

1. What did the root cause analysis identify?

2. Who does the safety manager report to?

3. What needs to be updated?

4. What system is being implemented for high-risk tasks?

5. What is the team now tracking?

Reading: Investigating a Near Miss

A second reading, a bit longer. Read it and answer the questions below.

After a worker flagged a near miss on the loading dock, the safety team began a full investigation. “We need to identify the root cause before someone actually gets hurt,” the safety manager said, starting a risk assessment of the area.

The team discovered a missing guard on the equipment and immediately took corrective action to mitigate the hazard. “We'll also update the safety protocol and enforce compliance more strictly during training,” she added, confirming that PPE requirements would be reviewed across the entire site.

1. What happened on the loading dock?

2. What did the safety manager want to identify?

3. What did the team discover?

4. What did they do to mitigate the hazard?

5. What will be reviewed across the site?
