In case of an accident at a nuclear reactor, the decrease of the radiation level is defined by the formula

1). Ät=Ä1∙t-0.5. 2). Ät=Ä1∙t-1.2. 3).Ät=Ä1∙t0.5. 4). Ät=Ä1∙t1.2.

3. Implementation of rescue breathing and closed-chest cardiac massage is performed in the following sequence:

1). 1. The injured is to be lied down on the back with a cushion under his neck with his head tossed back. 2. Clean out his oral cavity and extract the dentures. 3. The rescuer takes a deep breath and blows the air into the injured person’s mouth. 4. The rescuer presses onto the chest 4-5 times (chest deflection is 4-5 cm) with a frequency of 1time per second. 5. The rescuer repeats the operation 4) 10 - 15 times per minute until the breath and heartbeat are regained. 6. Effectiveness evaluation criteria: the pulse appearance, respiration, miosis, flushed skin. 7. If the breath and heartbeat aren’t regained in 45 minutes and there are no vital signs 6), the death is certified.

2). 1. The injured is to be lied down on the back with a cushion under his neck with his head tossed back. 2. Clean out his oral cavity and extract the dentures. 3. The rescuer takes a deep breath and blows the air into the injured person’s mouth. 4. The rescuer presses onto the chest 4-5 times (chest deflection 4-5 cm) with a frequency of 1 time per 2 seconds. 5. The rescuer repeats the operation 4) 10 - 15 times per minute until the breath and heartbeat are regained. 6. Effectiveness evaluation criteria: pulse appearance, breathing, miosis, flushed skin. 7. If the breath and heartbeat aren’t regained in 40 minutes and there are no vital signs, 6) the death is certified.

If the breath and heartbeat aren’t regained in 10 minutes and there are no vital signs 6) the death is certified.

4) 1. The injured is to be lied down on the back with a cushion under his neck and his head tossed back. 2. Clean out his oral cavity and extract the dentures. 3. The rescuer takes a deep breath and blows the air into the injured person’s mouth. 4. The rescuer exerts pressure on the chest for 4-5 times per a second (chest inflexion is 4-5 cm). 5. The procedure is repeated 4) 10-15 times per a minute until the breath and heartbeat are regained. 6. Effectiveness evaluation criteria: pulse appearance, breathing, miosis, flushed skin. 7. If the breath and heartbeat aren’t regained in 30 minutes and there are no vital signs 6) the death is certified.

4. Due to the scale and consequences emergency situations are classified as follows:

1). State level; region level; district level; local level, on-site level.



2). State level; region level; local level, on-site level.

3). State level; regional level; local level; on-site level.

4). State level; regional level; region level; district level; local level.


TEST 4

In the course of Life Safety

1. The active group factors can be divided into following subgroups:

1. sharp immovable objects, corrosion of materials, incrustation, insufficient structural toughness

2. mechanical, thermic, electrical, electromagnetic, chemical, biological, psychophysiological

3. corrosion of materials, incrustation, insufficient structural toughness, high loads on mechanisms and machines

4. sharp immovable objects, small constant of friction and surface irregularity together with slopes and lifts

2. Exposure dose is characterized by :

1. absorbed dose by the mass unit of the irradiated substance

2. the degree of biological irradiance impact on a human being

3. ionizing radiation energy, which is absorbed by the mass unit of the irradiated substance

4. ionizing radiation capacity in the air

3. Due to the priority and urgency degrees intensive cure unit measures are divided into following groups:

1. respiration and blood circulation support; intensive care performance; regulation of the central nervous system (CNS) functions, the liver, kidneys and the metabolism system

2. artificial respiration and artificial blood circulation support; regulation of the central nervous system (CNS) functions, the liver, kidneys and the metabolism system

3. artificial respiration and artificial blood circulation support; intensive care performance for breathing management and independent blood circulation; regulation of the central nervous system (CNS) functions, the liver, kidneys and the metabolism system

4. artificial respiration and artificial blood circulation support; intensive care performance for breathing management and independent blood circulation

4. Natural emergencies include:

1. geological, meteorological, hydrological, fire in natural ecological systems, biomedical;

2. geological, meteorological, hydrological, fire in natural ecological systems, biomedical, contagious diseases and mass poisoning of farm animals;

3. geological, meteorological, hydrological, fire in a natural ecological system, biomedical, contagious diseases, mass poisoning of farm animals, mass mortality of wild animals;

4. geological, meteorological, hydrological, fire in a natural ecological system, biomedical, contagious diseases, mass poisoning of farm animals, mass mortality of wild animals, agricultural plants morbid affection and pests.


 

TEST 5

In the course of Life Safety

 

1. Harmful and toxic agents of the second category are:

1). slightly hazardous agents: ammonia, acetone, benzole, ethanol, dust.

2). moderately hazardous agents: vanillin, mineral oils, detergents, tobacco, grain dust.

3). highly hazardous agents: acids, the vast majority of pesticides.

4). extremely hazardous agents: most insecticides, chlorine.

2. Equivalent dose is measured in:

1). Becquerel 1Bq=1 s-1

2). Gray 1Gr=J/kg.

3). Coulomb per kg = C/kg.

4). Sievert 1Sv=J/kg.

 

3. The duration of tourniquet use in case of arterial bleeding is limited by:

1). 2 hours.

2). 1 hour.

3). 1,5 hours.

4). 3 hours.

 

4. Due to the drift velocity, slips are divided into:

1). • slow (its speed is equal to several dozens of millimeters per year);

• medium (its speed is equal to several dozens of centimeters per year);

• fast (its speed is equal to several dozens of dozens of meters per year).

2). • slow (its speed is equal to several dozens of centimeters per year);

• medium (its speed is equal to several meters per hour or in a time);
