oxygen.
Polymerization - ✔️✔️Reactions in which two or more molecules chemically combined
to form a larger molecule.
Awareness level - ✔️✔️Lowest level of training established by OSHA for personnel at
hazardous materials incident. Recognize the presence for potential presence of
hazardous material and recognize that type of container at a site and identify the
material in it if possible. Transfer information to appropriate authority. Identify actions to
protect themselves. Have seen control isolating the hazardous area the denying entry.
Operations level - ✔️✔️Responders were trained and certified are individuals who
respond to releases of hazardous materials as Part of their normal duties. This
responders are expected to protect individuals, the environment, and property from the
effects of the release the defensive manner.
Cryogen - ✔️✔️-130°F to change to a liquid this is also called refrigerated liquid.
Oxidizer - ✔️✔️Any substance or material that yields oxygen readily may stimulate the
combustion of organic or inorganic matter.
Alpha radiation - ✔️✔️Stopped by the skim
Beta radiation - ✔️✔️Stopped by clothing
Gamma radiation - ✔️✔️Can pass completely through the human body or be absorbed
by tissue.
Neutron - ✔️✔️Ultra high energy particles that have a physical mass but no electrical
charge. They are highly penetrating.
Contamination - ✔️✔️Condition of impurity resulting from a mixture or contact with
foreign substance.
, Exposure - ✔️✔️Contact with a substance by swallowing, breathing, or touching skin or
eyes.
Contaminant - ✔️✔️Any foreign substance that compromises the purity of a given

Asphyxiant's - ✔️✔️Any substance that prevents oxygen from combining in sufficient
quantities with the blood or from being used by body tissues.
Systemic effect - ✔️✔️Something that effects and the entire system rather than a
single location or entity
Irritants - ✔️✔️Toxins that cost temporary but sometime severe inflammation of the
eyes skin or respiratory system.
Convulsants - ✔️✔️Toxic material that can cause convulsions involving muscular
contractions.
Virus - ✔️✔️The simplest type of micro organisms that can only replicate themselves in
living cells of their hosts.
Bacteria - ✔️✔️Microscopic single cell organisms do not cause disease in people. But
when they do they produce toxins and poisons.

Infectious - ✔️✔️Transmittable and able to infect people.
Contagious - ✔️✔️Capable of being transmitted from person-to-person via contact or
close proximity.
Routes of entry - ✔️✔️Inhalation, ingestion, skin contact, injection, and absorption.
Seven clues to the presence of hazardous materials - ✔️✔️1 occupancy type, location,
preincident surveys. 2 container shapes. 3 transportation placards, labels, and
markings. 4 other markings and colors. 5 written resources. 6 senses. 7 monitoring and
detection devices
Locations of most hazards - ✔️✔️Ports, docs or piers, railroad sightings, airplane
hangers, truck terminals, and other places of material transfer (warehouses).
Container shapes - ✔️✔️It is important for first responders to recognize the shape of
the different types of packaging and containers in which hazardous materials are stored
and transported.
