This exam question from the Traffic Rules of Ukraine concerns first aid and the safety of the driver and passengers in typical everyday situations related to transport. Electrolyte from a battery is a chemically aggressive liquid, and when it comes into contact with the skin, it can cause a chemical burn. Therefore, the correct initial actions should be simple, quick, and safe. Such knowledge is tested in the theoretical exam not just as a formality, but as a practical skill that may be needed during a traffic accident or while servicing a vehicle.
In terms of content, this question checks sections of the Traffic Rules related to the driver's duties and first aid (in particular, the logic of point 2.10 regarding the need to take possible measures to help victims), as well as indirectly the topic of equipping the vehicle with safety means (point 31.4.7, which mentions a first aid kit). The key idea: the first step in case of chemical injury by electrolyte is to stop the substance's contact with the skin as quickly as possible, and the most universal way to do this is prolonged and abundant rinsing with running water, which mechanically removes the electrolyte and reduces its concentration.
The analysis of the options in this exam question from the traffic rules is logical: the correct approach is rinsing with plenty of water, as this is a safe basic action that can be performed immediately and without the risk of making a mistake regarding the type of substance. Options involving treatment with iodine or hydrogen peroxide are not suitable, as they do not address the main task at the start — to quickly wash off the chemical — and may further irritate the damaged skin. The combination "perform all actions" is also incorrect, as it includes potentially harmful steps; in a real situation, after rinsing, if there are signs of a burn, it is appropriate to seek medical help.
Clause 2.10 — 2 “Duties and rights of drivers of motor vehicles” (driver's duties in case of involvement in a traffic accident)
A driver involved in a traffic accident is obliged, in particular, to take all possible measures to provide pre-medical assistance to the victims, call an emergency (ambulance) medical team, and (if necessary) arrange for the transportation of the victims to a healthcare facility.
This clause checks the general duty of the driver to possess pre-medical assistance skills and to apply them in emergency situations (while the exam question specifies one of the typical situations — chemical injury by electrolyte).
Clause 31.4.7 — 31 “Technical condition of vehicles and their equipment”, 4 “Technical malfunctions and conditions under which the operation of vehicles is prohibited”
The operation of vehicles is prohibited if the safety equipment required by the rules/standards is missing, in particular a first aid kit, emergency stop sign, and fire extinguisher (for the relevant categories of vehicles).
This clause is related to the topic of the question in that pre-medical assistance (including in cases of chemical injuries) requires the availability of basic means for initial actions, and the Traffic Rules establish the mandatory equipping of vehicles with a first aid kit.
Therefore, the correct answer is “Only rinse with plenty of water,” given that the Traffic Rules require the driver to be able to provide pre-medical assistance and have the necessary equipment, and the primary pre-medical action when electrolyte gets on the skin is immediate and copious rinsing with water to remove the chemical substance.
Electrolyte from a battery is a chemically aggressive liquid. When it comes into contact with the skin, it continues to "work" as long as it remains on the surface, so the main task of first aid for the driver is to stop the substance's contact with the skin as quickly as possible.
The safest and most effective first step in such a situation is thorough rinsing. A large amount of running water mechanically removes the electrolyte, reduces its concentration on the skin, and lessens the depth of chemical injury. That is why exam training questions emphasize a simple and universal action that can be performed immediately and without risk of error.
Attempts to "treat" the affected area with other substances without prior prolonged rinsing can be dangerous: it is possible to misidentify what has gotten on the skin (acid or alkali), or to worsen the irritation. Therefore, within the requirements of safe first aid for the driver, the correct tactic is not to experiment, but to rinse with water quickly and for a long time; if there are signs of a burn afterward, seek medical attention.
Thus, the correct answer is "Only rinse with plenty of water," since the priority is to immediately wash the electrolyte off the skin to stop the action of the chemical and reduce the damage.
