Identify the THREE surrounding conditions that should be evaluated when determining the potential harm at an incident.

- Size of the Breach - Size of the container - Wind direction and speed

Pressure Rail Car

-Enclosed Dome on top - 100-600 psi

Identify the THREE things that low pressure chemical cargo tank trucks (MC-307/DOT-407) typically carry.

-Flammable Liquids -Poisons -Corrosives

DANGER (pesticide)

-Is highly toxic by at least one route of exposure -May be corrosive, causing irreversible damage to the skin or eyes -May be highly toxic and even fatal if eaten, absorbed through the skin, or inhaled

WARNING (pesticide)

-Is moderately toxic if eaten, absorbed through the skin, or inhaled -Causes moderate eye or skin irritation

CAUTION (pesticide)

-Is slightly toxic if eaten, absorbed through the skin, or inhaled -Causes slight eye or skin irritation

Non-bulk packaging is defined as a packaging that has:

1. A maximum capacity of 119 gallons (450 L) or less as a receptacle for a liquid 2. A maximum net mass of 8oo pounds (400 kg) or less and a maximum capacity of 119 gallons (450L) or less as a receptacle for a solid 3. A water capacity of 1,000 pounds (454 kg) or less as a receptacle for a gas

The Three EPA signal words

1. CAUTION 2. WARNING 3. DANGER

As an Operations level responder, you respond to a leaking LPG tank that is next to a small shopping mall.

1. Guide people in and near the shopping mall to safety 2. Protect the overall environment 3. Protect the surrounding property from the effects of potential release

Bulk packaging is defined as a container that has no intermediate form of containment and has:

1.A maximum capacity greater than 119 gallons (450 L) as a receptacle for a liquid 2.A maximum net mass greater than 800 pounds (400 kg) and a maximum capacity greater than 119 gallons (450 L) as a receptacle for a solid 3.A water capacity greater than 1,000 pounds (454 kg) as a receptacle for a gas

Pressure railway tank cars can transport gases under pressures ranging from:

100-600 psi

General (nonpressure) car

4,000-45,000 g -Flammable/combustible liquids Flammable solids -Oxidizers -Liquid Poisons -Corrosives

Pressure railway cars

4,000-45,000 g 100-600 psi -Liquified gas -Gases -Water reactives -Toxics -Corrosives

Type C (Radioactive)

Air transport of highly radioactive materials.

A prerequisite for becoming certified as an operations level responder is that you must:

Be currently certified as an operations level responder.

MC-312 DOT(412)

Corrosives Cargo Tank -5-25 psi -4,000-6,000 gallons -corrosives, high specific gravity liquids -Round cross section -stiffener rings exterior

MC-338

Cryogenic -At least -130 degrees -Rear box cabinet -23-500 psi -liquid oxygen, hydrogen, carbon dioxide

Dewar Flasks

Cryogenic materials. 4-125 g

Analyze the HazMat incident

Determine the Magnitude of the problem in terms of outcomes

Plan the Initial Response

Determine the capabilities and competencies of available personnel.PPE, and equipment

The operations level goal for analyzing a HazMat Incident is to:

Determine the magnitude of the problem, in terms of outcomes, while performing your assigned tasks.

Type B (Radioactive)

Exceed Limits of Type A. In event of release, high radiation hazard to public and environment. Very large and heavy.

Implement the planned response

Favorably change outcomes consistent with the LERP and SOP

The minimum temperature at which a material gives off enough vapor to form an ignitable mixture with air is called the material's

Flash Point

Condensation

Gas to Liquid

MC-331

Gasses liquified by pressure -100-500 psi -2,500 - 11,500 gal -Propane, butane, chlorine, anhydrous ammonia -Rounded ends

Carboys

Glass, plastic, or steel container, (6-16 g) -Class 3 (Flammables) -Class 4 (Solids dissolved or suspended) -Class 5 (Oxidizers) -Class 6 (Poisons) -Class 8 (Corrosives)

Third goal

Implement the planned response to favorably effect the outcome.

At a HazMat incident, you are trying to favorably change the outcomes while performing your given tasks. The changes you're trying to make are consistent with your LERP and your organization's SOPs. The Operations level goal that you are fulfilling is:

Implementing the planned response.

vaporization

Liquid to Gas

Freezing

Liquid to Solid

MC-307 DOT(407)

Low-pressure bulk liquid -up to 40 psi -6,000 gallons max -mild acids -milk, water, combustibles

During a physical examination, Responder Lunt's doctor notices edema. The doctor runs some tests which reveal protein urea. Responder Lunt was recently exposed to a chemical hazard. Based on this information, which target organ effect is to blame?

Nephrotoxins

Second Goal

Plan the initial response

Vapor Pressure

Pressure exerted on the inside of a closed container by the vapor in the space above the liquid in the container

Vapor Density

Ratio of the weight of a vapor to the weight of an equal volume of air

Evaluate the progress

Review actions taken, ensure response objectives are being met safely, effectively, and efficiently

All of the following factors influence harm EXCEPT:

Speed at which the material spreads

You've covered a lot of ground so far. Let's make sure you remember it all! All of the following factors influence harm EXCEPT

Speed at which the material spreads

NFPA 704

Standard System for the Identification of the Hazards of Materials for Emergency Response. - "Fire Diamond" -Blue (Health hazards) -Red (Flammability) -Yellow (Chemical reactivity) - White (Specific Hazards)

Role of EPA (Environmental Protection Agency)

Through coordinating and implementing a wide range of activities, EPA conducts removal actions to protect human health and the environment.

Type A package (Radioactive)

Type A packages are designed and built for their durability under stress and must demonstrate their ability to withstand a series of tests without releasing their contents. High radioactive contents

First Goal

analyze the incident

Cryogenic railway cars

below 25 psi Temperatures of -130 and below. -Argon -Hydrogen -Nitrogen -Oxygen

MC-306 DOT(406)
