The Hassles of Storing Gasoline

Posted on by

To become more self-reliant we try to determine what ‘needed’ items to store; one to think about is fuel. Though there are several types of fuel preppers store: gasoline, propane, diesel, and kerosene; gasoline is the hardest to store long-term and, yet, is the most commonly used.

My main reason for storing gasoline is for use in our (gasoline) generator during a power failure. When people believe that disaster is looming–recently during Hurricane Irene, for example–they rush out and buy generators. But how many of them think to store fuel to run those generators? Our Generac 5000 generator has a five gallon fuel tank, it will run approximately five to seven hours on a tank of gasoline. My plan is to use our battery bank (four AGM deep cycle batteries) until depleted, then use the generator to recharge the batteries while still maintaining power to needed appliances. To ensure enough energy to last most power outages we need to store a reasonable amount of gasoline. But couldn’t we just drive to the gas station and get more gasoline? Maybe, but does the gas station have power?

We also want to store gasoline for our vehicles if we had to evacuate; gasoline may either be unavailable (gas station closed because of a power outage) or there may be excessively long lines to get it. We’d also like to have enough gasoline to take with us: to ensure we can reach our BOL, and to use there if power and/or gasoline aren’t available at our destination.

As we’re discussing storage it has to be stressed that gasoline is very flammable and must be stored in an appropriate container in a safe place. It is also relatively heavy–approximately 6.1 pounds per gallon–but at about 30 pounds for five gallons it can still be conveniently handled.

It’s hard to find definitive information about how long gasoline can be stored before it goes bad. But what does ‘bad’ even mean? Gasoline is a refined petroleum-derived chemical which–over time, and compounded by improper storing and temperatures–can break down by:

  • evaporation causing it to lose it’s volatile components (necessary for igniting)
  • drawing in water vapor that can cause separation – where water, since it’s heavier, settles to the bottom of the tank
  • oxidation causing it to become sludgy which can build up inside of small parts *

There are other unknowns, beginning with how old was the gasoline when you bought it (was it fresh from the refinery or already a month old?). What temperatures has it been exposed to and for how long? Was it properly stored by keeping it tightly covered, clean, dry, and cool? So, as a rule of thumb, if you plan to store your gasoline for more than a couple of months you should add a gasoline stabilizer.

The most common brand of stabilizer is Sta-Bil Gas Stabilizer. According to Sta-Bil’s website, using their product will keep fuel fresh for 12 months; you can double the dosage and fuel will remain fresh for 24 months. It’s added at a ratio of one ounce of Stabilizer to 2 1/2 gallons of gasoline. A 32-ounces bottle costs about $12, so it’s roughly $0.40 an ounce, which is only $0.80 for each 5-gallon gasoline can you store. If you store 30 gallons (check with local ordinances on amount you can legally store) it’d cost you less than $5.00 per year.

I add three ounces of Stabilizer (I want an extra buffer) to each 5-gallon container of gasoline (including the generator); we rotate the gasoline every 12 months (each can has a number which correlates with a month, i.e. #3 gets rotated in March). When it’s time to rotate, we just add five gallons into each vehicle’s half-full tank. We’ve found that pouring gas through the pour spout can get heavy and messy. So instead of pouring we use a Super Syphon; it self-primes, it’s easy to use, and it’s affordable. It takes about three minutes to syphon a 5-gallon can.

Plan ahead. If you invest in a generator, you need to have fuel for it. Remember that generator is for an emergency situation; don’t depend on a one that has old, or not enough, gasoline.

What I Did This Week To Prep 11/4/11

We had our first ‘lights out’ drill this week. Unfortunately I can’t call it a success, other than in the sense that we learn from our failures (hopefully).

Coming off the successful test of powering the deep freezer (for over four days), using the batter bank and inverter – I was ready to take the next step. This one was to see how the battery bank would do powering devices inside the house we would like to be able to use during a power outage.

My goal:

  1. Power two lamps, to light the living room / kitchen area, each with two CFL bulbs (compact fluorescent lamp – low energy)
  2. Power our 29 inch TV (older cathode ray tube type) and DVD player
  3. Charge the cell phones
  4. Use the microwave for limited cooking

Outcome:

  1. Batteries were discharged after about 1 1/2 hours of watching the movie (The Sting), and having the lamps on
  2. I forgot to charge the cell phones
  3. The microwave tripped the breaker after less than two minutes

What I learned:

  1. LED flashlights are great; I love our new Duracell Daylite LED two D cell flashlights
  2. Thoroughly check, and be familiar with, your equipment – before the incident
  3. Ensure the battery bank is fully charged
  4. The inverter shuts itself off when the batteries reach 10.50 volts
  5. Buying a quality system and running it through a cheap circuit breaker is dumb

What went well:

  1. Storing the main extension cord near the battery bank (14 gauge, 50 foot)
  2. Taking the opportunity to teach Ryan about the circuit breaker box
  3. Having plenty of accessory extension cords
  4. Once lamps were on (from batteries), putting the flashlights in a central place (easy to find in the dark)

If the power had really been out, we would have fallen back on our redundancy planning and gotten out the lanterns and candles.

The biggest mistake was assuming that since the battery bank, through the inverter, had been plugged in for almost a week that the batteries would be fully charged – so I didn’t think to check first. Yesterday (several days after the drill) I discovered the circuit breaker (a cheap plastic one)–between the batteries and the inverter–had failed and wasn’t allowing the batteries to charge. After seeing that I realized that during our drill our batteries probably weren’t fully charged (likely very low charge to begin with).

I rewired the batteries directly to the inverter (there’s still the inverter’s internal circuit breaker, the external one was a backup) and the batteries immediately began recharging. I’ll order a higher quality circuit breaker this weekend. When the breaker arrives, I’ll do an unofficial drill during the day and see how long the fully charged batteries will run the lamps, TV and DVD player. (Buying stuff is easy, this testing and figuring out is a pain…)

We also transplanted our pepper plants (one jalapeno and one habanero) from the garden into pots so we could bring them into the house for the winter. I hadn’t known until recently that peppers, in their natural habitat, are perennials; we think of them as annuals because our winters get too cold for them to survive. Next year we’ll just put the pot outside for the summer. So instead of starting with brand new plants again, we’ll have mature ones and see how they do. As a baseline, this year we got three, very mild, jalapenos and no habaneros at all.

Lastly, we had budgeted money for buying fish antibiotics this month. So I ordered AQUA-MOX (amoxicillin 500 mg, 100 capsules), AQUA-FLEX (cephalexin 500mg, 100 capsules) and AQUA-ZOLE (metronidazole 250mg, 100 tablets). I stored them away in a cool, dry, dark location in their original containers.

Expired, or Not Expired… Can You Store Medications Long Term?

Posted on by

What medications* do we keep in our preps? We store: 1) over-the-counter (OTC) drugs: ibuprofen (Motrin), acetaminophen (Tylenol), aspirin, diphenhydramine (Benadryl), pseudoephedrine (Sudafed), loratadine (Claritin), guaifenesin (Mucinex), and 2) antibiotics (that I recently posted about): amoxicillin, cephalexin, ciprofloxacin, doxycycline, metronidazole.

How long can they be stored? They have expiration dates, does that mean they go bad?

Let’s start with what do drug expiration dates mean? Required since 1979, the expiration date is the last date that the pharmaceutical company will guarantee 100% potency (some sources state at least 90% potency). So then we ask, how long does it take a drug to lose it’s beneficial effects?

That is the question that the Department of Defense (DOD) asked the Food and Drug Administration (FDA) in 1985 (the military had over a billion dollars worth of medication stored). So in response, in 1986, the DOD and the FDA began the Shelf Life Extension Program (SLEP).

The SLEP program is documented in the Wall Street Journal article, Many Medicines Are Potent Years Past Expiration Dates, by Laurie P. Cohen, March 28, 2000. The military submitted, and the FDA has evaluated, over 100 drugs – prescription and OTC. The results showed that about 90% of them were safe and effective well past their expiration dates, some for 10 years or longer. Joel Davis, a former FDA expiration-date compliance chief, said that with a handful of exceptions – notably nitroglycerin, insulin and some liquid antibiotics – most expired drugs are probably effective.

In light of these results, a former [FDA] director of the testing program, Francis Flaherty, says he has concluded that expiration dates put on by manufacturers typically have no bearing on whether a drug is usable for longer.

Mr. Flaherty notes that a drug maker is required to prove only that a drug is still good on whatever expiration date the company chooses to set. The expiration date doesn’t mean, or even suggest, that the drug will stop being effective after that, nor that it will become harmful.

“Manufacturers put expiration dates on for marketing, rather than scientific, reasons,” said Mr. Flaherty, a pharmacist at the FDA until his retirement in 1999. “It’s not profitable for them to have products on a shelf for 10 years. They want turnover.”

The Harvard Medical School Family Health Guide, in Drug Expiration Dates – Do They Mean Anything?, notes that, with rare exceptions, “it’s true the effectiveness of a drug may decrease over time, but much of the original potency still remains even a decade after the expiration date”.

Where and how medications are stored is an important factor in minimizing their degradation. Storing in a cool, dry, dark place will maximize their lifespan; when possible keep sealed in their original container until ready to use. Medications stored in bathroom cabinets or shelves could have effectiveness significantly reduced. Be sure to discard any pills that become discolored, turn powdery, or smell overly strong; any liquids that appear cloudy or filmy; or any tubes of cream that are hardened or cracked.

Dr. Bones, from The Doom and Bloom Show, states in his blog post, The Truth About Expiration Dates, “I put forth to you this recommendation: Do not throw away medications that are in pill or capsule form after their expiration dates if you are stockpiling for a collapse. Even if a small amount of potency is lost after time, they will be of use when we no longer have the ability to mass-produce these medicines. I’m aware that this is against the conventional medical wisdom, but we may find ourselves in a situation one day where something is better than nothing.”

Post Script: Dealing With The ‘Tetracycline Becomes Toxic’ Myth

There has long been a belief that the antibiotic tetracycline becomes toxic once it has past it’s expiration date.

In Medscape Today’s article, Do Medications Really Expire?, they discusses the original case, “A contested example of a rare exception [of expired drugs possibly becoming toxic] is a case of renal tubular damage purportedly caused by expired tetracycline (reported by G. W. Frimpter and colleagues in JAMA, 1963;184:111). This outcome (disputed by other scientists) was supposedly caused by a chemical transformation of the active ingredient.”

The case was thoroughly evaluated in the 1978 article, Tetracycline in a Renal Insufficiency: Resolution of a Therapeutic Dilemma, it states, “”Old” and degraded tetracyclines have previously been demonstrated to have direct toxic effects on the renal proximal tubule, but because of changes in manufacturing techniques this is no longer a real problem.” It also states, “It has often been stated that the tetracyclines should be avoided in patients with severe renal disease, but, as we shall see, doxycycline represents an important exception to the rule”.

In Cohen’s article on the Shelf Life Extension Program, Many Medicines Are Potent Years Past Expiration Dates, it goes on to state, “Only one report known to the medical community linked an old drug to human toxicity. A 1963 Journal of the American Medical Association article said degraded tetracycline caused kidney damage. Even this study, though, has been challenged by other scientists. Mr. Flaherty says the Shelf Life program encountered no toxicity with tetracycline”.

Dr. Bones and Nurse Amy, from The Doom and Bloom Show, when interviewed on TSP, clearly state that tetracycline past it’s expiration date is safe (episode 736, beginning at 43:45). Nurse Amy concludes the topic with “. . . if they can just get that in their heads that tetracycline isn’t going to kill you when it’s past expiration”.

Medical evidence supports that tetracycline, past it’s expiration date–especially in the form of doxycycline–is as safe as any other expired antibiotic.
