Propane Can Be Dangerous

Propane has many safety advantages:

  • It’s non-toxic
  • Won’t ignite at temperatures less than 920 degrees Fahrenheit
  • It doesn’t harm soil or even groundwater.

However, the fact remains that it is a flammable gas, and even the smallest spark can cause ignition, resulting in property damage or even worse. If you smell propane, inside or outside your home, take the matter very seriously.

Checking Your Stove

If you smell propane and all your burners are in the ‘OFF’ position, you should check the connections on your stove. If the connections are all secure, and your propane tank is full, then it’s safe to assume that you have a propane leak.

Sometimes when your tank is nearly empty you will smell the last of the propane dumping out. This is not a cause for concern. However, if the smell grows more powerful as time goes on, or doesn’t go away, then it’s an indicator that there’s something more serious going on.

Recognizing The Smell Of Propane

Propane has a powerful and unpleasant smell, similar to that of rotten eggs, or the spray of a skunk. Manufacturers deliberately add these scents to aid users in becoming aware of leaking gas, which is, of course, a significant safety hazard. If there is propane in the vicinity in the case of any such foul odor, you must always act immediately.

First, ensure that the unpleasant odor is propane and not from any other origin, such as:

  • Garbage
  • Sewage
  • Skunk spray
  • Dead vermin

If the odor is faint, it may not be necessary to be alarmed. Sometimes a slight smell of propane can remain even after a stove is lit. Other causes could be a pilot light in a gas fireplace or the pilot light of a water heater has been extinguished.

Any possible gas leak should be taken seriously. Take special care and immediate action if:

  • The odor is incredibly strong
  • It doesn’t go away
  • It is accompanied by a hissing sound.

If You Smell Gas

The first rule is: do not permit anything with flames or sparks to be used. Remove and extinguish all smoking materials as well as other flames such as candles. Also, don’t switch on equipment that could spark or give off an electrical charge. This doesn’t only mean lighters and open flames.

Be careful with everyday items such as:

  • Rotary phones
  • Electrical switches
  • Doorbells
  • Heating thermostats

A spark from any of these could trigger an explosion or a major fire.

Actions To Take

  • Ensure you and those near you leave the area without delay. If the odor is inside the home, get everyone out immediately.
  • When the smell of gas is outdoors, move away from the area. Use the same precautions about sparks and flames. Vehicles and outdoor electrical equipment can also present a safety risk. Move everyone to a safe distance, on foot, and don’t try to identify or resolve the issue yourself.
  • Turn off the main gas supply valve on the propane tank. Only do so if it’s safe for you to take this action. To shut the valve, turn it clockwise.
  • Without delay, report the gas leak to the relevant authorities. Do this from a neighbor’s house or another location nearby. Call your local propane retailer immediately. If they’re not reachable, contact 911 or the fire department.
  • Under no circumstances return to your property. Wait until it has been checked and declared safe by the propane seller, the emergency response team, or a qualified gas service technician has given the all-clear.
  • Wait for a professional. Before using any of your propane equipment, a propane retailer, or a qualified gas service technician will need to check your complete installation to ensure that the system is leak-free.

If You Detect A Gas Leak

Without delay, evacuate the entire household and call your propane supplier or the fire department from a neighbor’s phone. Familiarize yourself with the smell of propane. Propane suppliers offer scratch-and-sniff cards to assist your family in identifying its special odor.

Also, always make sure you call 811 before you excavate. It’s important to know where gas lines are situated to avoid damaging them when you dig in the yard.

Can You Smell It?

Certain people may find it hard to smell propane, possibly because:

  • They have colds, allergies, sinus congestion, etc.
  • A reduced sense of smell due to tobacco, alcohol, or drug use.
  • The scent is masked by tobacco smoke, cooking smells, or strong odors.
  • Older people tend to have a reduced sense of smell
  • When propane is present for a period of time, the fragrance is no longer detected.
  • The propane odor may be in a part of the building which is not frequently visited.
  • Odor loss can occur – that is, the smell of the propane itself weakens over time.

If you are worried that you or those around you may find it difficult to detect the smell of propane, think about installing one or more propane detectors.

Stay Safe And Know The Risks

No-one doubts that propane fumes can be hazardous. However, serious leaks rarely occur, and they usually only happen after long term neglect of the condition of the tank or heating system. It is wise to invest in professional maintenance by professional technicians.

Why does my stove smell like gas when it’s off?
If your stove’s knobs are turned off but aren’t fully clicked into the off position then your stove may still be leaking gas. Also, the fuel lines themselves can have a gas leak, or the connector that attaches the line to the stove might be loose. Check these issues to rule them out before taking further steps.
Can the smell of gas from a stove kill you?
At certain levels, a propane leak can suffocate you to death. It can have the same effect as carbon monoxide in that it prevents your body from absorbing oxygen.
Can you get carbon monoxide poisoning from a gas stove?
Your propane stove and oven can be a source of carbon monoxide. Although, this is in mild concentrations. Regardless of the kind of stove you have, it’s a good idea to have a carbon monoxide detector in your home.

Play It Safe

Upon smelling propane, you should check behind your stove to make sure that the connectors are tight, and that the fuel line doesn’t have any puncture holes in it from rodents, or from kinks that were in the hose. If you see that your stove isn’t the issue, you need to remove yourself and family, as well as your pets, from your home and follow the protocols above.
Although propane is relatively safe, it’s not a gas that you want to mess with. If you’re unsure what’s going on, it’s better to call someone and have it be for nothing, than not call for help and have it be something serious.
