Lithium batteries are generally safe and unlikely to fail, but only so long as there are no defects and the batteries are not damaged. When lithium batteries fail to operate safely or are damaged, they may present a fire and/or explosion hazard. Damage from improper use, storage, or charging may also cause lithium batteries to fail.
While there is not a specific OSHA standard for lithium-ion batteries, many of the OSHA general industry standards may apply, as well as the General Duty Clause (Section 5(a)(1) of the Occupational Safety and Health Act of 1970). These include, but are not limited to the following standards:
