What incidents should be investigated?Question 3Answera.Serious incidentsb.Near missesc.All incidentsd.a & b

The incidents that should be investigated include:

a. Serious incidents: These are incidents that have resulted in significant harm or damage. They could include accidents that have caused injuries or fatalities, or incidents that have resulted in significant property damage. These incidents are critical to investigate to understand what went wrong and how similar incidents can be prevented in the future.

b. Near misses: These are incidents that could have resulted in harm or damage, but didn't. For example, if a piece of equipment fails but no one is injured, that's a near miss. These incidents are important to investigate because they can provide valuable information about potential risks and hazards.

c. All incidents: This would include not only serious incidents and near misses, but also minor incidents that may not have resulted in any harm or damage. Even these minor incidents can provide useful information about potential risks and hazards, and investigating them can help prevent more serious incidents in the future.

d. a & b: This option suggests that only serious incidents and near misses should be investigated. While these are certainly important to investigate, it's also beneficial to investigate all incidents, as explained above.

So, the most comprehensive answer would be c. All incidents should be investigated.
