Ch 50 Flashcards
(16 cards)
Which of the following statements regarding the warm zone at a hazardous materials incident is correct?
- The warm zone is also known as the contamination zone and is only accessible by properly trained rescuers.
- It may be necessary to perform urgent lifesaving care in the warm zone before a patient is fully decontaminated.
- Patients who are brought to the warm zone by trained rescuers should already have been decontaminated.
- A standard-size warm zone is generally 50 feet in all directions, but may be smaller depending on the incident.
It may be necessary to perform urgent lifesaving care in the warm zone before a patient is fully decontaminated.
Upon arriving at the scene of an overturned tanker truck or train derailment, you should be most suspicious that a hazardous material is involved if:
- multiple patients are unconscious or are experiencing respiratory distress.
- any type of fluid is leaking from the overturned tanker or railroad car.
- a visible cloud or dark smoke is escaping from the tanker or railroad car.
- the truck driver or train conductor is unconscious and still in the vehicle
multiple patients are unconscious or are experiencing respiratory distress.
An individual trained at the hazardous materials operations level is trained to:
- make direct, intentional contact with a hazardous material.
- care for patients contaminated with a hazardous material.
- perform patient care activities outside of the hot zone.
- recognize a hazardous materials incident but not provide patient care.
perform patient care activities outside of the hot zone
Which of the following actions can reduce the level of contamination of a person by as much as 90%?
- Using large pads to absorb the chemical
- Flushing with copious amounts of water
- Removing the patient’s clothing
- Using an agent to neutralize the chemical
Removing the patient’s clothing
Level A personal protective equipment:
- is required when a technician needs protection from splashes and inhaled toxins but does not need to be fully encapsulated.
- is designed to protect the rescuer against a known agent and is worn with an air-purifying respirator.
- fully encapsulates the hazardous materials technician, including their self-contained breathing apparatus.
- provides the same degree of protection as a fire fighter’s turnout gear and is typically worn in the cold zone.
fully encapsulates the hazardous materials technician, including their self-contained breathing apparatus.
Which of the following is an example of a local effect of a hazardous material?
- Blister formation
- Nausea and vomiting
- Restlessness
- Blood in the urine
Blister formation
A blue placard specifically indicates that a chemical is which type of hazard?
- Reactivity
- Explosive
- Health
- Fire
health
Prior to accepting a patient who has been decontaminated by the hazardous materials team, the paramedic must:
- be informed about the degree of decontamination.
- make contact with the receiving medical facility.
- receive a verbal report about the material involved.
- don the appropriate personal protective equipment.
don the appropriate personal protective equipment.
It is important to park your ambulance upwind and uphill from a hazardous materials incident scene because:
- if the chemical ignites and explodes, the fallout from the blast will most likely sink into valleys and ditches instead of rising.
- the vapor density of many chemicals is less than that of the air, causing the vapor to rise and dissipate as it travels with the wind.
- hazardous chemicals that turn to gas rarely have a vapor density that is heavier than the air, regardless of the amount of chemical.
- the risk of being contaminated is minimal if the chemical travels, and you will have greater visibility of the entire incident scene.
the vapor density of many chemicals is less than that of the air, causing the vapor to rise and dissipate as it travels with the wind.
Medical monitoring and rehabilitation of rescuers at the scene of a hazardous materials incident should routinely include:
- prophylactic analgesia in order to prevent pain.
- prophylactic IV boluses of an isotonic crystalloid.
- a complete set of vital signs and ECG monitoring.
- documentation of the number of victims involved.
a complete set of vital signs and ECG monitoring.
Which of the following would be of greatest value when trying to determine the type of hazardous material a commercial tanker truck is carrying?
- Bill of lading
- Consist
- Waybill
- Dangerous cargo manifest
bill of lading
When a base substance is placed on a burn caused by an acid:
- heat is generated as a by-product of the reaction.
- the burn will be confined to the epidermis.
- an exothermic reaction is less likely to occur.
- the toxicity of the acid is effectively neutralized.

A Computer-Aided Management of Emergency Operations (CAMEO) device is used by hazardous materials teams to:
- determine a hazardous material’s explosive limits by monitoring wind speed and environmental temperature.
- help predict downwind concentrations of hazardous materials based on the input of environmental factors into a computer model.
- determine the pH of the hazardous material, which will assist in identifying the most appropriate neutralizing agent to use.
- monitor the levels of hydrogen sulfide and carbon monoxide contained in a wide variety of hazardous materials.

The direct exposure of a patient to a hazardous material is called:
- primary contamination.
- acute infection.
- chemical transference.
- systemic intoxication.
