Lithium Battery for Memory Logging - Safety Requirement Alert
16 April 2019
Recently we found out that Lithium Battery for Memory logging (Pressure survey, MPLT, Memory Caliper, Memory Video Camera, etc...) is required D-class fire extinguisher and NIOSH/MSHA approved respiratory protectional available as well as isolate / monitor it for 5 days in case of mechanical shock. 
"Do not crush, pierce, short circuit (+) and (-) battery terminals with conductive (metal) goods. Do not directly heat or solder. Do not throw into fire. Do not mix batteries of different types and brands. Do not mix new and used batteries. Keep batteries in non-conductive (plastic) trays. Cells or batteries that have been dropped or experience mechanical shock should be isolated and monitored for approximately 5 days to identify a possible internal short circuit and resulting fire. In case of rupture: Handle in accordance with good industrial hygiene and safety practice. Ensure adequate ventilation. Avoid contact with skin, eyes and clothing. Do not breathe vapors/dust. Wear personal protective equipment."


"None required under normal usage. If exposure limits are exceeded or irritation is experienced, NIOSH/MSHA approved respiratory protection should be worn. Positive-pressure supplied air respirators may be required for high airborne contaminant concentrations. Respiratory protection must be provided in accordance with current local regulations."

May some of you are well aware of this issue but some might miss this point.

I believe none of you have ever seen the lithium battery on fire.

Basically, they pray a lot because lithium-ion batteries are in everything; laptops, cameras, phones, watches, etc.

The US TSA wanted to ban them from cabins, but the various airline associations said 'hey, wait a minute, a small fire in the cabin we can handle, a fire we can't get to in a luggage bin, not at all'.

Hi Mr. Dave,
I wish I could do as what we have been done here for 20 years. it is just turned out and stopped us from anyway.

Lithium battery is everywhere, however downhole battery do not have any sentence says ex-proof, but D-class fire extinguisher available.

Then I totally agree with Mr. Scott.

Hi Dave,

I understand that the great majority of airlines will not take consignments of Lithium Batteries as cargo in the holds of their passenger aircraft.

There were moves afoot a couple of years ago to ban Lithium battery shipments on all aircraft, because of the fire risk.

I don't think that this has got anywhere yet, partially because of the difficulty in shipping Lithium batteries by sea - apparently they are very susceptible to corrosion in salt laden environments.

You may recall that a couple of years ago, airlines banned certain models of a mobile phone (Samsung Galaxy Note 7) from the passenger cabin because a design fault meant that the battery was prone to catching fire.

All the Best

Hi folks

Thinking out aloud: I wonder what the airlines do?  They have to deal with this I believe.

Kind regards

Thanks Grant.
We are searching for D-class provider, but exhausted here due to limited supplier. Only Amerex-fire is sort-out, but their distributor in Vietnam could not provide (small amount of 2 ea).

Is there anyone can provide: Class D Fire Extinguisher – Model B571?

Our memory logging operation is suspended three month already due to this issue and only can be done with Class D fire extinguisher available.

Can you all help me to get "
Class D fire extinguisher"

Many thanks for your help.

Its why reputable logging companies secure their lithium battieries in well padded dry storage containers for shipping offshore. Yes, lithium makes a hell of a fire if exposed to water.
