Developed by William Haddon in 1970, the matrix looks at factors related to personal attributes, vector or agent attributes, and environmental attributes before, during and after an injury or death

Occupational fatality

An occupational fatality is a death that occurs while a person is at work or performing work related tasks. Occupational fatalities are also commonly called “occupational deaths” or “work-related deaths/fatalities” and can occur in any industry or occupation....

. By utilizing this framework, one can then think about evaluating the relative importance of different factors and design interventions.

A typical Haddon Matrix looks like this :

	Personal Factors	Vector or Agent Factors	Physical Environmental Factors	Social Environmental Factors
Pre-event
Event
Post-event

Pre-event

1. Prevent the existence of the agent.
2. Prevent the release of the agent.
3. Separate the agent from the host.
4. Provide protection for the host.

Event

1. Minimize the amount of agent present.
2. Control the pattern of release of the agent to minimize damage.
3. Control the interaction between the agent and host to minimize damage.
4. Increase the resilience of the host.

Post-event

1. Provide a rapid treatment response for host.
2. Provide treatment and rehabilitation for the host.
