Class 1 Divisions Acronym
``` Many (Mass explosion) People (Projection hazard) Find (Fire hazard) Me (Minor explosion) Very (Very insensitive) Extreme (Extremely insensitive) ```
30
What is the major hazard associated with class 2 gases?
BLEVE: boiling liquid expanding vapor explosion
31
What happens during a BLEVE?
IN A NUTSHELL: if a fire/extreme heat is applied to a container holding liquid, the liquid will turn to gas and the pressure will build until the container explodes.
32
What is a Division 2.1 hazard? Give an example
Flammable gas (ex. propane)
33
What is a Division 2.2 hazard? Give examples.
Nonflammable, nonpoisonous, compressed gas/ cryogenic gas (ex. liquid nitrogen, cryogenic argon)
34
What is a cryogenic gas?
- cryogenic = very low temperatures | - cryogenic gases are vaporized cryogenic liquids, which are cold and have extremely low boiling points
35
What is a Division 2.3 hazard? Give examples.
Poisonous gas (ex. anhydrous ammonia, chlorine)
36
What is the major hazard associated with class three hazards?
They burn readily
37
What is the definition of a flammable liquid? Give examples.
A liquid having a flash point of less than or equal to 140 degrees F (examples: gasoline, acetone, and methyl alcohol)
38
What is the definition of a combustible liquid?
A liquid with flash points between 100-200 degrees F (examples: diesel fuel, kerosene, mineral oil, peanut oil, No. 6 fuel oil)
39
What is the major hazard associated with Class 4 hazards?
Rapid and spontaneous combustion with a release of toxic smoke.
40
What is a Division 4.1 hazard?
Includes three types of flammable solids: 1. Wetted/Desensitized Explosives 2. Self-Reactive Materials 3. Readily Combustible Solids
41
What are Wetted/Desensitized Explosives (4.1)? Give examples.
Explosive properties suppressed by wetting with sufficient alcohol plasticizers or water
42
What are Self-Reactive Materials (4.1)? Give an example.
materials liable to undergo a strong exothermic decomposition (ex. zirconium powder)
43
What are Readily Combustible Solids (4.1)?
solids or powders that can be ignited (ex. magnesium)
44
What is a Division 4.2 hazard? What are examples?
Spontaneously combustable materials, to include: - Pyrophoric Material - Self Heating Material examples: aluminum alkyls, charcoal briquettes, magnesium alkyls, and phosphorus
45
What is Pyrophoric Material?
can ignite within 5 min of coming into contact with air
46
What is a Self Heating Material?
a material that, when in contact with air, is able to self heat
47
What is a Division 4.3 hazard? Examples?
Dangerous When Wet Materials, which can become spontaneously flammable or give off flammable or toxic gas when wet. Examples: magnesium powder, potassium metal alloys, and sodium hydride
48
What is a Division 5.1 hazard?
They are OXIDIZERS, which support combustion and intensify fires by yielding oxygen.
49
What is a Division 5.2 hazard?
They are ORGANIC PEROXIDES and the hazard is that they are unstable/reactive explosives
50
What is an Organic Peroxide?
any organic compound containing oxygen in the bivalent structure that may be considered a derivative of hydrogen peroxide, where one or more of the hydrogen atoms have been replaced by organic radicals. Materials are assigned to one of seven types:
51
Describe Division 5.2 Type A
can detonate/deflagrate rapidly as packaged. TRANSPORT IS PROHIBITED.
52
Describe Division 5.2 Type B
Neither detonates nor deflagrates rapidly, but can undergo a thermal explosion.
53
Describe Division 5.2 Type C
Neither detonates nor deflagrates rapidly and cannot undergo thermal explosion
54
Describe Division 5.2 Type D
Detonates partially/deflagrates slowly, with medium to no effect when heated
55
Describe Division 5.2 Type E
Won't detonate/deflagrate, low/no effect when heated
56
Describe Division 5.2 Type F
won't detonate/deflagrate, low/no effect if heated and low/no explosive power
57
Describe Division 5.2 Type G

61
What is the major hazard associated with class 7 materials?
radioactive burns
62
What is the definition of radioactive materials (class 7)?
any material containing radionuclides where both the activity concentration and the total activity in the consignment exceed specified values (example: yellow cake)
63
What is the major hazard associated with Class 8 materials? Examples?
burns/emulsification skin damage. examples: nitric acid phosphorus trichloride, sodium hydroxide, sulfuric acid
64
What defines a corrosive?
a liquid or solid that causes full-thickness destruction of skin at the site of contact within a specified period of time
65
What is the definition of a Class 9 hazard?
a material that presents a hazard during transport but that is not included in another hazard class that could cause extreme annoyance or discomfort to a flight crew member so as to prevent performance of assigned duties
66
Define ORM-D
Other Regulated Material Domestic: a material that presents a limited hazard during transportation due to its form, quantity, and packaging.
67
What are the 7 indicators of HAZMAT?
1. occupancy types, locations, pre-incident surveys 2. container shapes 3. placards, labels and markings 4. other markings and colors 5. written resources 6. senses 7. monitoring and detection devices
68
What is the purpose of Pre-Incident Plans?
provides guidance to allow responders to make quick and accurate decisions during hazmat incidents
69
Illegal lab locations include:
vehicles, campgrounds, hotel rooms
70
When do we use placards vs labels?
Placards are for bulk packaging and labels are for nonbulk.
71
Where can you find the UN/NA number of a substance?
1. the Emergency Response Guidebook (ERG) provides a key to the four-digit identification 2. the shipping papers
72
What are the six types of energy release?
1. heat 2. mechanical 3. pressure 4. electricity 5. chemical 6. radiation
73
What are the mechanisms of harm?
- energy release - corrosivity - toxicity - be aware of sudden change in conditions: pressure, temp, fire
74
What are the protective measures of awareness level responders?
- avoid becoming a victim | - remember you most likely do not have respiratory protection or personal protective clothing
75
What are the Isolation/Protection Actions?
1. establish isolation perimeter 2. deny entry 3. evacuate/shelter in place
76
What are the types of Hazmat exposures?
Acute (single exposure within a short time) and Chronic (long term and recurring)
77
What are the effects of Hazmat exposures?
- Acute Effects: short term effects that appear within hours to minutes or days - Chronic Effects: long term effects may take years to appear, such as cancer - Delayed effects: doesn't hurt the body right away, can occur hours or days later
78
What information will you have when using pipelines?
good question..
