HAZWOPER Risk Assessment
The top priority of incident response is the safety of responders and the general public. Risk assessment is the most important aspect of an incident response because the incident cannot be managed safely if the problem and risks are not understood. Failure to do a risk assessment can result in serious injuries or death. Each incident is unique, so deciding what to do and when, can be difficult. This module will cover various hazard identification techniques to help you make better decisions when responding to hazardous material incidents.

Key Questions
What is risk?
Risk is defined as the probability that a hazard will actually cause harm.
What are the steps of a risk assessment?
The first step of a risk assessment is to identify the materials involved and their hazards. Next, it is critical to determine the current status of the incident and predict what could happen next.
How can hazards be identified?
Some clues that can help identify materials and their hazards are the type of container, placards, markings, labels, shipping papers, SDSs, and detection equipment.
What is the General Hazardous Materials Behavior Model?
The General Hazardous Materials Behavior Model (GEBMO) defines a sequence and the behavior of a container and its contents involved in a hazardous materials incident.
What are the GEBMO events?
In chronological order, the GEMBO events are stress, breach, release, dispersion, exposure, and harm.
Sample Video Transcript
Each incident is different and there are many factors that can affect risk, including: • Toxicity, flammability, corrosivity, or reactivity of the materials involved. The greater the hazards, the greater the risk. • Quantity of material that is released and that which is still inside containers. Generally, the greater the quantity, the greater the risk, but small quantities of extremely hazardous materials can be a significant risk. • Type of container and its integrity. • Surrounding environmental conditions. • Site topography. • Availability and capability of responders.
