EM: Ch. 2 hazards and risk assessment

Question 1

Hazards

Answer 1

Source of danger that may or may not lead to an emergency or disaster and is named after the emergency/disaster that could be so precipitated

Question 2

Risk

Answer 2

The interaction of a hazard likelihood and the consequences should it occur

Question 3

Emergency event

Answer 3

One that requires the efforts of one or more of the emergency services to manage

Question 4

Disaster

Answer 4

An emergency event that exceeds the capacity of emergency services in one or more critical areas

Question 5

Types of Hazards

Answer 5

1. Natural- Natural hazards are those that exist in the natural environment and pose a threat to human populations and communities, and these hazards are often exacerbated by irresponsible human development. Floods, hurricanes, avalanches.
2. Technological Hazards- Technological hazards are generally those that are caused by the actions or presence of man, whether intentional, accidental or otherwise. Some of the more common technological hazards include HAZMAT, Fires, terrorism, nuclear accidents.

Question 6

Hazards Risk Management

Answer 6

s the processes by which individuals, communities, and countries deal with the hazard risks they face. Assessments can be qualitative or quantitative and are dependent upon data accuracy. The process involves hazard identification, hazard risk assessment, hazard risk analysis, and hazard risk treatment.

Question 7

Risk treatment technologies

Answer 7

have improved our ability to manage risk considerably over the past fifteen years, and have included such things as imaging and sensing systems, modeling, communication systems, and mapping. Earth quakes Measured by the Richter Scale or Modified Mercalli Intensity Scale, hurricanes (74mph June 1 to Nov 30)Described using the Saffir-Simpson Scale. •Tornadoes Measured by the Enhanced Fujita-Pearson Scale. Can be found in the tornado alley during TX,OK, AR, MO, and KS.

Question 8

The four steps of HRM?

Answer 8

A four-step process that includes: •Identifying the hazards•
Assessing risk for each hazard identified•
Analyzing hazard risks in relation to each other•
Treating hazard risk according to prioritization

Question 9

HRM assessment is based on what two factors

Answer 9

Risk calculated according to two equal factors:

•Hazard likelihood •Hazard consequence

Question 10

Hazard Risk Analysis

Answer 10

•Determines the relative seriousness of hazard risks that have been identified and assessed. Done by using a risk matrix.

Question 11
