Batteries
are a potential hazard that requires higher scrutiny due to the potential harm
they can cause (most specifically Lithium batteries of all types). In fact, we
have all seen the headlines of battery explosions or fires. But now there are
new regulations, some in effect and others coming very soon that will limit
what and how you ship, carry on, and package batteries (again most specifically
Lithium batteries of all types). These regulations will no doubt provide a
means of reducing the potential risk batteries may cause in the shipment and
storage processes, but these regulations are only half of the
story and focuses more on reactive measures.
Proactively,
most batteries need to be designed properly to handle the environment, as well
as the abuse they may experience such as short circuits, overcharging, drops,
and high temperatures without catching fire or causing harm or damage. Most
equipment that batteries power, has safety features to
prevent catastrophic failure. However, batteries shipped or stored outside
their intended equipment need to be handled appropriately to decrease risks.
What should your battery supplier be doing to help ensure your
batteries are safe while shipping and in storage? Below are 5 things to
consider.
1. The packaging should be of appropriate construction and properly
labeled (New regulations require Lithium batteries of specific size and types
to be considered Hazmat by the DOT and packaged, labeled and shipped
appropriately.)
2. The inside packaging method is one to ensure the highest level of
protection for the
batteries from physically damage and/or possibility of short circuits or
dangers evolution of heat.
3. Ensure your supplier has done the appropriate testing on lithium batteries
and
documentation should be available to users if requested (example - UN T1-T8
test for Lithium content batteries)
4. If they are shipping batteries that are considered hazardous by
the DOT (lithium and
Lithium Ion, etc.) then do they subscribe to a 24-hour
hazardous materials communication service, such as Chemtrec? This is an
optional service to manufacturers and distributors to help clearly identify to carriers
and customers what is in the box and who to call if a potentially hazardous
situation may arise. For more
information refer to US DOT Regulation 49 CFR §172.604.
5. Are they ISO certified and regularly audited? The higher the
quality system they have
the better the consistency and diligence they will have in ensuring
all possible battery hazard risks are reduced.
If a supplier is not proactive in testing and complying to the new and upcoming DOT regulations, they may not be
able to ship certain types and sizes, and tighter restrictions are in place for
October 2009.
So partnering with a reputable and quality minded supplier is a
smart choice as it will reduce your battery risks and ensure supply of your
needed battery solutions. For additional
