Lithium Ion batteries: safety issues

Share

This relatively new generation of batteries are used in so many devices today that it is hard to imagine not having their convenience.

From portable power tools, to flashlights, mobile phones, computers, toys, and so much more.

In December last year, a fire in a tool storage shed deep in an Ontario mine was contained after some difficulty.

Findings this week determined the fire occurred while charging a number of lithium-ion batteries used by the miners portable tools. While it couldn’t be accurately determined if the fire began in the battery, the charger, the extension cord, the presence of several of the batteries together made the fire much harder to contain once it started.

When conventional dry chemical (ABS) fire extinguisers were tried by two miners who discovered the fire, it only made the fire worse.

The investigation recommended Class D fire extinguishers be used in such cases.

In June last year, a Vancouver-bound flight was forced to return to Calgary shortly after takeoff when a warning light indicated a fire in the cargo hold.

Investigation showed that two small Li-On batteries for an e-cigarette had caught fire, burning the passenger’s bag and slightly damaging the cargo floor.

The airline policy indicated Li-Ion batteries are not to be put in checked luggage.

In a case in September, a used Li-Ion battery (or batteries) which had been put into someone’s garbage, caught fire at a Fredericton, New Brunswick landfill. When a worker tried to put the fire out, a battery exploded slightly injuring him.

Luckily this fire was caught in time before it burned the entire house, when a portable drill was left on charge and the battery exploded and burned. (Marcheta Fitzgerald – Halifax Fire and Emergency)

While there are millions of devices used safely with such batteries, there are now hundreds of cases of fires and burns caused by them.

Safety recommendations for Li-Ion batteries include not charging devices on flammable surfaces like chesterfields or cushions which can absorb the heat, not overcharging them, not fast charging, using ony recommended chargers for that device and not uncertified chargers.

Dropping a Li-ion battery can also cause components inside the compact batteries to come into contact. If that happens, a short circuit and immediate fire can occur.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.

Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
