In the article, we will consider the norm of ppm for drivers.
If you drive a vehicle while intoxicated, you will definitely be punished. However, ethanol can be found in the body of even those people who on this or the previous day did not drink alcohol at all. A similar effect is given by certain medicines and foods consumed by drivers on the eve of the trip.
We will talk about the norm per mille for drivers in 2018 below.
What is ppm?
Every driver should know the statutory allowable blood ethanol standards.
It is known that strong drinks and some medicines contain alcohol. In addition, alcohol is present in certain foods.
Effects
This substance, getting into the body, leads to intoxication, which provokes the appearance of the following effects:
- The activity of the cerebral cortex is inhibited.
- The body's reactions slow down.
- Disturbed mental abilities, coordination of movements.
- The attention quickly dissipates.
- There is a violation of visual acuity.
By ppm means a quantitative value. Using it, the degree of intoxication resulting from the use of substances containing ethanol is determined. What is the permissible rate of alcohol while driving in ppm?
So, this indicator makes it possible to identify the presence of alcohol in the body. But 1 ppm is how much? For example, 1/10 ppm says that about 0.045 mg of ethanol is contained in a liter of blood.
Alcohol from the human body is excreted for a long time. This fact should be taken into account before consuming strong drinks, certain foods, or medications if driving is expected in the near future.
If a person drinks 100 ml of vodka, then he can only drive after 5 hours. After drinking a glass of wine, driving is possible no earlier than 4 hours later.
Norm ppm for drivers
We study the norms that are acceptable for all drivers without exception.
For persons who drive vehicles after using substances that contain ethanol, administrative liability is provided. It occurs in the event that the presence of ethanol is detected in the blood.
To check the presence of ethanol in the body and its compliance with the norm ppm for drivers, a device called a breathalyzer is used. To check, you need to exhale through the tube a certain amount of air. The display of the device will display the amount of alcohol contained in the blood. Many are interested in authorized ppm for drivers.
In 2017, the dose of alcohol consumed should have been less than 0.35 mg / l (if a blood test is performed). If this indicator is exceeded, the traffic police have the right to assert that the driver being checked is intoxicated.
What is the norm ppm for drivers in 2018? The legislation has changed, and it has become possible to confirm a citizen’s drinking before a trip not only through laboratory tests of blood samples. At the same time, the permissible norms of alcohol for drivers have changed, amounting to 0.3 ppm (when determining alcohol in the blood). If control is carried out using a breathalyzer, then its readings should not exceed 0.16 ppm. This indicator is the maximum allowable. If it is exceeded, car owners can be suspended from driving.
The rate of alcohol in the blood must be remembered.
When is a blood test needed?
A blood test is supposed to be carried out in cases where the drunken state of the driver cannot be confirmed by using specialized devices.
A similar measure is necessary in cases:
- When a citizen driving a vehicle is in an unconscious state and is not able to independently pass a test using a breathalyzer.
- When the driver is in a state of excessive intoxication. When driving and while being in an altered state of consciousness, people are a danger to themselves and others.
Drivers who drive a car or other vehicle and are in a state of intoxication are sent for a medical examination (examination), which involves the obligatory delivery of blood samples for examination.
In the case when laboratory tests confirm that there is more than the permissible alcohol rate at the wheel in ppm (more than 0.3), there is reason to consider the citizen being tested drunk. For this offense, he will have to bear responsibility, which is prescribed by law.
Determination of alcohol concentration in the blood
Previously, the only method was used with which it was possible to objectively assess the condition of the driver, as well as confirm the presence of ethyl alcohol in his blood - by examining blood samples. However, in some situations, for example, on highways and highways, determining the degree of intoxication in this way is practically not possible.
Portable detectors
That is why mobile devices have been developed that allow you to quickly identify the maximum ppm for drivers. These are portable detectors. The mechanism of their work is to determine alcohol by analyzing the exhaled breath from the lungs. In the process of calculating the volume of ethanol in the human body, a number of certain parameters are taken into account, among which:
- The amount of ethanol contained (in volume drunk).
- The total volume of fluid in the body of a citizen undergoing examination.
- The gender of the driver.
- Weight indicators.
- The percentage of ethyl alcohol to the total body weight of the surveyed citizen.
Self settlement
The degree of intoxication of the driver can be calculated independently. For example, we use the following indicators: human body weight - 80 kg; the amount of vodka consumed, which contains 40% ethanol, is 250 mg; the total volume of fluid contained in the body of an adult citizen is 70%.
This means that the volume of liquid will be equal to 70% * 80 kg = 56 kg. To calculate the amount of pure ethyl alcohol, 40% should be multiplied by 250 mg: 40% * 250 mg = 100 mg. If you take into account the density of ethanol, you can get the volume of pure ethyl alcohol: 100 mg * 0.79 g / mol = 79 g.
When making calculations, an error not exceeding 10% should be taken into account. In this regard, the exact amount of pure ethyl alcohol will be 71.1 grams. Given the above data, you can easily determine the number of ppm: 71.1 / 56 = 1.27.
How long is alcohol determined in exhaled breath?
The period of removal of alcohol vapor from the human body depends on a variety of factors, including:
- The presence of chronic pathologies of internal organs (heart, kidney, lungs, liver).
- Type, amount of drinks consumed.
- Weight, age.
- Gender
- Individual tolerance of ethyl alcohol.
It is known that in the body of different people, ethyl alcohol is absorbed at different speeds. That is why the duration of its presence in exhaled air can vary significantly. For example, alcohol is eliminated from the body of men much faster than from the body of women.
Also, the amount of alcohol consumed, the mixing factor of different drinks, affects the elimination time. In addition, the duration of the content of ethyl alcohol strongly depends on whether a person has chronic pathologies or not. So, in people suffering from liver diseases, alcohol will be excreted for a very long time.
If a citizen is in a state of binge drinking alcoholic beverages for 2 days or more), he will not be able to undergo an examination with the breathalyzer and will not be allowed to drive a vehicle. Moreover, the presence of ethanol in the blood and, accordingly, exhaled air will be observed for approximately 72 hours.
Also, the amount of food that a citizen ate when drinking alcohol has an effect on the period of removal of ethyl alcohol from exhaled air. If strong alcohol was consumed without food, alcohol vapors will be detected for a long time. If a person ate heavily and drank alcohol, the process of removing alcohol vapor will pass quickly enough.
For different drinks
How many ppm is acceptable for the driver, it is important to find out in advance. The average duration of alcohol vapor removal from exhaled air differs for different drinks. For example, when used:
- Cognac in the amount of 100 grams ethanol will be removed about 4-4.5 hours.
- 200 ml of vodka (40%) - 7-7.5 hours.
- 100 ml of champagne - 1-1.5 hours.
- 100 ml of dry wine - 2.5-3 hours.
- 500 ml of light beer - 40 min.
Medicines and food products, after the use of which ethanol can be detected in the blood
It is also important for drivers to consider that there are products that are not recommended to be consumed immediately before driving. They provoke fermentation processes in the body, resulting in the formation of a certain amount of ethyl alcohol.
Among them:
- Kvass.
- Overripe bananas.
- Dairy products.
- Juices.
Non-alcoholic beer and oranges should be included in the same list. In addition, you can not use fresheners for the oral cavity, since ethanol is present in their composition.
If we consider drugs, then their list is quite extensive, since medical alcohol is an essential component of many of them.
The most popular medications containing alcohol are:
- Levovinisol.
- "Liquorice root".
- Bittner (this drug contains about 40% ethyl alcohol).
- "Biovital" (alcoholic extract of hawthorn extract).
- "Kanefron N".
- “Rinital” (a homeopathic medicine containing alcohol).
To drugs, the alcohol content of which is quite high (about 43%), the following can be attributed:
- Gentos.
- "Vokara."
- Aflubin.
- Drops Asinis.
Separately, it is worth noting the medicines of the group of cardiac drugs, which are used by quite a lot of drivers. Take them on the eve of the trip with extreme caution. Among these drugs:
- "Valoserdin."
- "Barbated."
- Valocardin.
The basis of these drugs are phenobarbital and ethyl alcohol. In addition, it is worth remembering the well-known Corvalol, which, in addition to alcohol, contains barbiturates.
It is not recommended to take funds that are actively advertised by the media and supposedly eliminate the characteristic smell and all the symptoms of alcohol intoxication. Such means in nature does not actually exist. They are likely to block a characteristic odor, but they are not able to influence the breathalyzer testimony.
Conclusion
It is important to note that knowing how to calculate the ppm and which foods and medicines contain ethanol, allows the driver to get rid of the serious consequences arising from an accident. And also to avoid paying significant sums of money as fines due to their own carelessness.
We reviewed ppm rates for drivers. We hope that the article will help you to be more careful and get rid of troubles on the road.
