Lithium batteries can be found in everything from mobile phones and e-cigarettes to cordless tools, laptop computers, electric cars, and industrial battery backup and energy storage systems to name just a few of their many applications. These power-packed energy storage devices allow for exceptional mobility with their small footprint. Lithium batteries are also long lasting, fast charging and generally stable. However, there can be a dark side to lithium batteries. They can burn, go into thermal runaway, and can be extremely difficult to extinguish.
The Occupational Safety and Health Administration (OSHA) reports: “Lithium batteries are generally safe and unlikely to fail, but only so long as there are no defects and the batteries are not damaged.” Damage to lithium batteries can occur instantaneously or over time from physical damage, from thermal variations (high or low), from erroneous charging or from control system failures.
When lithium batteries fail to operate safely or become damaged, they can present a fire hazard, an internal pressure explosion hazard, a toxic gas emission hazard and/or a flammable gas emission hazard. In addition to the heat and explosion dangers, there are also environmental and exposure issues to consider. These include, but are not limited to, hydrogen fluoride, hydrogen cyanide, hydrogen gas and metal particulates (like nickel, cobalt, manganese, lithium, iron, etc.).
With dramatic differences in structures, usage, quantities and other variables, there is no one-size-fits-all approach to lithium battery safety. Because of these variations, it is important to carefully plan for safe daily operations and for emergent events like an explosion or fire.
Fortunately, there are mitigation strategies to help prevent injury and thermal events involving the use of lithium batteries. For businesses and institutions, partnering with experienced environmental, health and safety professionals, and local fire departments, can help to mitigate threats to employees, the public, physical assets, and the environment.
These are just a few of the many things to know about lithium battery fires and potential exposure risks. To learn more about this or other industrial hygiene, environmental, health or safety issues, please visit the websites shown on below.

![Secondhand Marijuana Smoke Exposure Risks
Secondhand tobacco smoke exposure has long been recognized as a health concern for nonsmokers. With the increasing number of states that now allow medical marijuana and recreational marijuana use, secondhand cannabis smoke, more commonly referred to as marijuana smoke, has also become a concern for many.
According to the Centers for Disease Control and Prevention (CDC):
Smoked marijuana has many of the same cancer-causing substances as smoked tobacco, but there are still a lot of unanswered questions around secondhand marijuana smoke exposure and its impact on chronic diseases such as heart disease, cancer and lung diseases.
Secondhand marijuana smoke does contains tetrahydrocannabinol (THC), the chemical responsible for most of marijuana’s psychological effects. The smoke is also a complex mixture of many other chemicals and particulate matter (PM). Exposure to PM can cause lung irritation, may trigger an asthma attack in some people with the condition, and can be a concern for people who have COPD or other lung diseases.
The California Office of Environmental Health Hazard Assessment lists marijuana smoke as a carcinogen and reproductive toxin on its Proposition 65 list. Some of the substances found in marijuana smoke listed by OEHHA include 1,3-butadiene, arsenic, benzene, benzo[a]pyrene, cadmium, carbon monoxide, hexavalent chromium, hydrogen cyanide, formaldehyde, lead, mercury, nickel and toluene.
Some people also have concerns about whether they would fail a drug test or could become impaired from being around secondhand marijuana smoke. Factors such as ventilation rates, proximity to the smoke, and how long someone is inhaling the secondhand smoke are all issues to consider.
These are just a few of the many things to know about secondhand marijuana smoke exposure risks. To learn more about this or other indoor air quality, building science, environmental, occupational, health or safety issues, please visit the websites shown below.
