Pressure Cooker Explosion: What You Need To Know

Pressure Cooker Explosion: What You Need To Know

Pressure cookers have become a common kitchen device because they can cook meals quickly and effectively. However, there are instances where pressure cookers can malfunction and lead to dangerous situations such as explosions. This article will explore the causes of pressure cooker explosion, the associated risks, and essential tips to prevent such incidents.

What is a Pressure Cooker?

A sealed cooking pot called a pressure cooker uses steam pressure to cook food. It consists of a pot with a locking lid and a pressure release valve. When heat applies to the pot, the liquid boils and creates steam. The steam builds pressure, raising the temperature and cooking the food faster than traditional methods.

How Does a Pressure Cooker Work?

When using a pressure cooker, the lid locks tightly to create a sealed environment. As the liquid inside boils and turns into steam, the pressure builds up, which increases the temperature beyond the boiling point of water. The high pressure and temperature allow the food to cook faster and retain more nutrients.

Understanding Pressure Cooker Explosions

Causes of Pressure Cooker Explosions

Pressure cooker explosions can occur due to various reasons, including:

  • Blockage in the Pressure Release Valve: If the pressure release valve is blocked or clogged, the pressure inside the cooker can continue to rise beyond safe levels, leading to an explosion.
  • Faulty Sealing Ring: The sealing ring ensures a proper seal between the lid and the pot. If the sealing ring is damaged or not correctly positioned, it can result in pressure buildup and subsequent explosion.
  • Overfilling the Cooker: Overfilling the pressure cooker can cause excessive steam production and pressure buildup, increasing the risk of an explosion.
  • Improper Maintenance: Neglecting regular maintenance, such as not cleaning the pressure release valve or failing to replace worn-out parts, can compromise the pressure cooker’s safety.

Dangers of Pressure Cooker Explosions

The dangers associated with pressure cooker explosions are significant and should not be underestimated. Some potential risks include:

  • Burn Injuries: The high-pressure steam and hot contents released during an explosion can cause severe burns to anyone close to the cooker.
  • Projectile Hazards: When a pressure cooker explodes, it can send metal fragments, boiling liquid, and scalding steam flying in all directions, threatening people nearby.
  • Property Damage: Pressure cooker explosions can damage surrounding property, including kitchen countertops, cabinets, and other appliances.

Signs of a Faulty Pressure Cooker

It’s critical to be aware of warning signals that a pressure cooker is malfunctioning to avoid an explosion. Look out for the following:

  • Difficulty Locking the Lid: If you need help locking the lid securely, it may indicate a problem with the sealing ring or the locking mechanism.
  • Leaking Steam: Steam leaking from the sides or lid of the pressure cooker when in use suggests an improper seal, which can lead to pressure buildup and potential explosions.
  • Inconsistent Pressure Buildup: If the pressure inside the cooker fluctuates significantly during cooking, it could indicate a malfunctioning pressure release valve or other internal issues.

Preventing Pressure Cooker Explosions

To ensure your safety while using a pressure cooker, follow these preventive measures:

Proper Maintenance and Care

  • Regularly Inspect the Sealing Ring: Look for any evidence of deterioration on the sealing ring, such as cracks or tears, and replace it if necessary. Clean the sealing ring and the lid thoroughly to remove debris or food particles.
  • Keep Pressure Release Valve Clear: Periodically remove and clean the pressure release valve to prevent blockages. Ensure it moves freely and is not obstructed by any residue.
  • Follow the Manufacturer’s Instructions: Read and understand the user manual provided by the manufacturer. Adhere to the recommended usage guidelines and maintenance procedures.

Safety Tips for Pressure Cooker Usage

Do Not Overfill: Follow the recommended fill level specified in the cooker’s manual to avoid excessive pressure buildup.

  • Release Pressure Properly: Always follow the correct procedures for releasing pressure from the cooker. Avoid quick-release methods and allow the pressure to release naturally.
  • Avoid Opening When Under Pressure: Never open the pressure cooker while still under pressure. Wait until the pressure has completely dissipated before unlocking the lid.
  • Monitor Cooking Times: Set a timer to ensure you don’t overcook food. Overcooking can lead to excessive steam production and pressure buildup.
  • Stay Present: Do not leave the pressure cooker unattended while it’s in use. Being present allows you to address any potential issues promptly.

What to Do in Case of a Pressure Cooker Explosion

In the unfortunate event of a pressure cooker explosion, follow these steps:

  • Ensure Safety: Move away from the exploded cooker and protect yourself from immediate hazards.
  • Attend to Injuries: If anyone is injured, seek medical attention immediately.
  • Document the Incident: Take pictures of the explosion, the damage caused, and any injuries sustained. This documentation can be useful for insurance claims or legal purposes.
  • Report the Incident: Notify the pressure cooker’s manufacturer about the incident, providing them with the relevant details.

Pressure Cooker Explosions Myths Debunked

Myth 1: Pressure Cookers Are Dangerous and Should Be Avoided

Reality: Pressure cookers are safe and efficient cooking appliances used correctly and maintained properly. The key is to follow the manufacturer’s instructions and take necessary safety precautions.

Myth 2: All Pressure Cookers Are Prone to Explosions

Reality: Explosions in pressure cookers are uncommon and frequently result from user error or poor maintenance. High-quality pressure cookers with appropriate safety mechanisms significantly reduce the risk of explosions.

Myth 3: Quick Release Method Is Always Safe

Reality: The quick-release method should only be used for foods that do not produce a lot of foam or splatter. The natural release method is safer for certain recipes to avoid sudden pressure changes.


Pressure cookers can be valuable to any kitchen, providing fast and convenient cooking. However, it’s essential to understand the risks associated with pressure cooker explosions and take appropriate preventive measures. You can enjoy the benefits of pressure cooking without compromising safety by properly maintaining the cooker, following safety guidelines, and being vigilant while cooking.

Frequently Asked Question

Can I use any pressure cooker on an induction cooktop?

No, not all pressure cookers are compatible with induction cooktops. Check the product specifications or consult the manufacturer to ensure compatibility.

Is using a pressure cooker with a damaged sealing ring safe?

No, a damaged sealing ring can compromise the pressure cooker’s ability to create a proper seal. It’s essential to replace the sealing ring if it is damaged.

Can pressure cookers explode even when used correctly?

While pressure cookers are generally safe when used correctly, there is still a minimal risk of explosion. Following safety guidelines and proper maintenance significantly reduces this risk.

Can I leave the pressure cooker unattended while it’s in use?

Leaving a pressure cooker unattended while it’s in use is not recommended. It’s important to monitor the cooking process and address any potential issues promptly.

Can I open the pressure cooker immediately after releasing the pressure?

No, waiting until all the pressure has been released is crucial before opening the pressure cooker. Opening it prematurely can result in dangerous steam release.
