Many consumers transitioning to modern cooking appliances often worry about the harm of induction cooktops to health. These concerns mainly revolve around electromagnetic radiation and electrical incidents. The following article will provide an objective answer based on standards!
Are induction cooktops harmful when used?
Induction cooktops do not harm health if used correctly and according to standards.
Although many people are concerned about the electromagnetic field generated when the cooktop operates, which poses health risks similar to smartphones or microwaves, the reality is that the electromagnetic field produced by this device falls within a very low frequency range (about 20kHz – 50kHz) and diminishes to nearly zero at a distance. This wavelength is completely insufficient in energy to cause biological cell changes.
Moreover, genuine products must pass stringent tests regarding the limits of electromagnetic radiation set by ICNIRP and the IEC 60335 household electrical safety standard. Risks only truly arise when users purchase low-quality counterfeit products, improperly install the power supply, or overlook basic safety principles while cooking.
5 harms of induction cooktops when used incorrectly
Although the technology itself is safe, incorrect usage habits, lack of product knowledge, or using low-quality products can lead to the following harms:
Risk of fire and electrical overload when using the wrong power source
Induction cooktops have very high power (up to 4000W – 7000W). If plugged into the same outlet as other devices or using wires with too small a cross-section, the current will exceed the wire’s load capacity. This situation can cause the wire insulation to melt, leading to short circuits and potentially resulting in fires.
Using multiple high-power devices simultaneously with the induction cooktop can cause explosions
Risk of electric shock if used when the glass surface is cracked
The glass surface of the induction cooktop acts as an insulating barrier between the user and the electrified circuit board. If the glass is cracked due to impact and you continue to cook, water and liquids can seep through the cracks down to the induction coil. This situation can cause short circuits, damage components, and pose a direct electric shock risk during operation.
Risk of fire and explosion due to low-quality components or incorrect installation
Counterfeit induction cooktops are often designed with poor heat dissipation systems and low-quality components. Additionally, installing the cooktop in a tightly sealed cabinet without ventilation for the cooling fan will cause the circuit board temperature to rise, accelerating breakdown and potentially causing fires or explosions.
Electromagnetic field effects on individuals with pacemakers or implanted medical devices
The varying electromagnetic field of the induction cooktop generates eddy currents at the bottom of the pot. Even at low frequencies, this electromagnetic field can still interfere with the control signals of implanted medical devices such as pacemakers if the user stands too close to the active cooking area.
According to Dr. Phùng Anh Tuấn, this radiation decreases rapidly with distance, reducing by about 103 times at 1 meter. Therefore, you only need to maintain a distance of 10 – 20cm to avoid affecting the devices.
When using the induction cooktop, you should stand at least 20cm away to ensure safety and avoid being affected by electromagnetic waves
Electromagnetic field effects on pregnant women
Claims that induction cooktops cause miscarriages or severely affect fetuses are unfounded. According to experts, the radiation from induction cooktops is very low and within safe limits. However, according to recommendations from the Central Obstetrics Hospital, pregnant women should still maintain a distance from electrical devices, about 10 – 20cm from induction cooktops, to limit unnecessary exposure and ensure a safer living environment.
7 safe and effective ways to use induction cooktops
To ensure safety when using and optimize cooking performance, users need to follow some basic principles below.
- Choose the right magnetic cookware: Only use pots and pans with magnetic bottoms (430 stainless steel, cast iron) to optimize heat transfer efficiency.
- Ensure sufficient power supply before installation: The induction cooktop needs to be connected through a circuit breaker (CB) from 25A – 45A depending on the cooktop’s power, with a cross-section of 4mm² – 10mm².
- Do not use if the glass surface is cracked: If the crack is small (under 5cm), located far from the cooking area and control panel, you can use it temporarily if the glass is still flat and not exposing components. However, if the crack is severe or located right in the induction area, turn off the power immediately.
- Clean the cooktop regularly: After each use, wipe off grease and food residues with a soft cloth to keep the cooktop shiny, operating steadily, and to avoid burnt residues sticking to the surface.
- Maintain a safe distance while cooking: When the cooktop is in operation, stand at a distance of 10cm to 30cm from the glass surface. This distance allows you to operate comfortably while minimizing exposure to heat and emitted electromagnetic waves.
- Do not place the cooktop near other electronic devices: Avoid installing the induction cooktop right next to TVs, radios, or other signal transmitting devices. The electromagnetic field of the cooktop when operating at high power can interfere with the signals of these devices.
- Consult a doctor for special cases: Individuals using implanted medical devices (pacemakers) or pregnant women should consult a specialist about the safe cooking distance before using the induction cooktop.
Clean the cooktop after use
Above is a summary of 5 harms of induction cooktops when used incorrectly and 7 notes for safe and effective use of induction cooktops. We hope this article helps you understand the nature correctly, proactively prevent risks, and use induction cooktops effectively and sustainably over time.
To minimize risks and ensure a stable user experience, prioritize choosing induction cooktops with high-quality components, fully integrated safety features, and clear certifications. Among them, Köcher induction cooktops are a worthy consideration due to their application of German standard technology and optimal design that ensures durability, safety, and suitability for the long-term needs of Vietnamese families.
