Haz Mat Ch 4 Flashcards
What is the primary role of first responders trained to the Operations Level?
To protect nearby persons, contain the release from a safe distance, and prevent exposures from the effects of the release.
What does the APIE-T process involve for Operations Level Responders?
Analyzing the incident.
What is involved in analyzing the incident for Operations Level Responders?
Identifying and assessing the on-scene hazards.
What knowledge is required for Operations Level Responders when assessing hazards?
Knowledge and understanding of the materials involved and the hazards they present.
After analyzing the incident, what do Operations Level Responders begin to do?
Plan an appropriate response based on their training and standard operating procedures (SOPs).
Fill in the blank: The first responsibility of the Operations Level Responder is to _______.
analyze the incident.
True or False: The first responders’ role includes protecting life, the environment, and property.
True
What problems can a hazmat release from a container create?
It can create many problems affecting people, living organisms, other chemicals, and the environment.
How do a material’s physical and chemical properties affect its behavior?
They determine how the material behaves, the harm it can cause, and the effects on everything it contacts.
What influences how a container behaves if it is damaged or ruptured?
A material’s physical and chemical properties influence how a container will behave if damaged.
What do first responders need to collect?
First responders need to know how to collect hazard and response data that provide information about the substance’s physical and chemical properties.
How can proper resources assist first responders?
Proper resources can greatly assist the responder in determining the present hazards, estimating the potential harm, and predicting how the incident may progress.
What are physical properties?
Physical properties are the characteristics of a material that do not involve the chemistry or chemical nature of the material.
What do physical properties describe?
Physical properties describe how a material behaves in relation to physical influences, such as temperature and pressure, or how a material behaves when mixed with, or compared to, another material.
What are some examples of physical properties?
Materials can be characterized by the following physical properties: states of matter, melting point/freezing point/sublimation, vapor pressure, boiling point, specific gravity, molecular weight, particle size, persistence and viscosity, appearance and odor, water solubility/miscibility, and vapor density.
What are the three states of matter?
Gas, Liquid, Solid
Why is it important to learn about the physical state of hazardous materials?
Because gaseous, liquid, and solid hazardous materials behave differently, influencing their potential hazards.
How does understanding the states of matter help with hazardous materials?
It helps predict where the hazardous material is going, what exposures it may affect, and what those effects may be.
What does the state of matter indicate about hazardous materials?
It indicates what exposures that material may become and helps determine if there will be far-reaching hazardous properties.
What is the general mobility of solids compared to gases?
Solids are the least mobile, while gases have the greatest mobility.
How does the state of a substance change with temperature?
A substance’s state may change if the temperature changes.
What happens to a solid when the temperature increases?
A solid may change to a liquid if the temperature increases.
What factors should be considered regarding a substance’s state in outdoor incidents?
You should consider the temperature’s effect on a substance, as air temperature and weather factors can strongly influence its state of matter and behavior.
What are the potential dangers of gas incidents for emergency responders?
Incidents involving gases are potentially the most dangerous for emergency responders.
