Flammable Liquids

Someone needs some HAZCOM and ER training

This video is a great example of two failures: 1) Hazardous Communications and 2) Emergency Response recognition. There is no way he should have walked into the spill, much less into the spray to stop the leak. That was gasoline—NOT diesel; even if it had been diesel, his actions were still out of line. We…...

Did we learn from the Stapleton Air Port Tank Farm Fire (1990)

Contributing to the severity and duration of the fire was the lack of storage tank fail-safe control valves and internal fire valves and the location of the control building in the containment area where fuel leaks are likely to occur. The National Transportation Safety Board determined that the probable cause of the fire at the…...

Failing to control flammable vapor results in severe injuries for by-stander (video)

A video I posted over two years ago has come full circle. A citizen (some may call him homeless) was allowed to sit (and smoke) within 20′ of a gasoline tanker unloading operation at a gas station. His actions may not have been his sole demise, as we can see in the video evidence that…...

Gasoline fueling leads to a flash fire; caused by static?

A fuel tanker was filling the station’s gas reserves when two vehicles began fueling at the pumps. According to security camera footage, not long after, one of the pumps suddenly bursts into flames as a result of built-up static electricity….

If my bonding/grounding system’s resistance to ground needs to be <10/25 ohms, then why is ESD footwear allowed a resistance of 1,000,000 ohms?

This is another Top 10 question on flammable liquids safety I get from clients, cold calls, referrals, and friends. Most are familiar with the testing limits for path to ground on bonding/grounding stations of 10/25 ohms. In my previous post tonight I explained where these 10 and 25 ohm limits came from and how they…...

If 1 meg-ohm is adequate resistance to ground, then why do we test to 10 or 25 ohms?

Theoretically, a resistance to ground of 1,000,000 ohms is considered capable of dissipating a static electrical charge. So why then does my safety program (and NFPA 77) require a resistance to ground of 10 or 25 ohms OR LESS, depending on the metal used in my system? (e.g. end-to-end resistance of a bonding wire should…...

1983 Newark 1.8 Million Gasoline Storage Tank Explosion

On January 7, 1983, at approximately 12:15 am EST, a massive explosion, ignited by an overflowing gasoline storage tank at the Texaco storage facility in Newark, NJ, and a nearby incinerator, destroyed three tanks, killing one person and injuring 24, while the blast was felt up to 100 miles away. Cause:The explosion was said to…...

Static electricity from flowing gasoline?

Gasoline (UN1203) is a NON-conductive flammable liquid. These liquids, as all liquids, generate static electricity as they flow through hoses, piping, and free fall into tanks and containers. Since the liquid is non-conductive, it can not conduct the static charge to the hose/pipe/container so the charge can be dissipated to the “ground”. Authorities say quick…...

Scrubbing the inside of a mix tank with Naptha using a Teflon bristle brush is not advised

Another incident where the lack of respect for static electricity and flammable atmospheres results in severe injuries. A Teflon bristle brush generates a lot of static electricity; coupled with the low flashpoint of Naptha (73F) and we have a serious hazard. At 5:30 a.m. on February 24, 2020, an employee, 42, was scrubbing interior surfaces…...

Switch Loading + Static Electricity = Fatal Burns

FACT: Most flammable liquid vapors have a Minimum Ignition Energy (MIE) of less than 1 millijoule (mJ). Most of us do not even feel static which is less than 15 mJ. So the amount of energy necessary to ignite most flammable vapor atmospheres is not even observable by humans. At 6:15 p.m. on October 30,…...
