As data centers adopt lithium-ion UPS batteries, thermal runaway has become a distinct emergency scenario with its own warning signs and response protocol, different from traditional lead-acid battery incidents. This course covers thermal runaway recognition, containment, and emergency response specific to lithium-ion systems.
You'll leave understanding why lithium-ion response differs from lead-acid procedures, and how to coordinate correctly with fire services on a lithium-ion-specific incident.
What You'll Learn
- Recognize the early warning signs of lithium-ion battery thermal runaway
- Apply correct containment procedures during a thermal event
- Coordinate emergency response with fire services for lithium-ion incidents
- Understand why lithium-ion response differs from lead-acid battery incidents
Course Modules
Thermal Runaway Fundamentals
What causes it, and why lithium-ion batteries behave differently under stress.
Early Warning Signs
Recognizing a developing thermal event before it escalates.
Containment Procedures
What to do, and not do, during a thermal runaway event.
Emergency Response Coordination
Working with fire services on a lithium-ion-specific incident.
Why This Matters in a Data Center
Lithium-ion batteries are replacing lead-acid in many UPS systems because they are smaller, lighter and last longer. They also bring a different emergency: thermal runaway, where a cell overheats and releases flammable and toxic gases, and heat can spread from cell to cell. A lithium-ion battery fire can reignite after it appears to be out.
Codes and test methods have developed quickly. NFPA 855 covers the installation of stationary energy storage systems, and UL 9540A is the test method used to evaluate how thermal runaway spreads. Facility staff need to recognize early warning signs such as off-gas alarms and abnormal temperatures, know the facility's containment steps and coordinate with the fire department. This course covers thermal runaway fundamentals, early warning signs, containment and emergency response coordination.
Safety Scope & Limits
Applicable standards and regulations
- Your facility's emergency action plan (OSHA 29 CFR 1910.38) and fire prevention plan (1910.39)
- OSHA 29 CFR 1910.120(q) applies to workers who respond to hazardous substance releases; this course does not meet its training requirements
What this course does
- Explains how thermal runaway starts and spreads, and the warning signs to watch for.
- Prepares staff to recognize an event early, raise the alarm, and follow the facility's evacuation and notification steps.
What it does not do
- Does not qualify you as an emergency responder or train you to fight a battery fire. Firefighting and hazardous materials response belong to the fire department or a trained response team.
- Does not replace your facility's emergency action plan or drills.
An online course alone does not make anyone qualified for hazardous work. Under OSHA rules, the employer decides who is qualified, based on training plus demonstrated skill on the specific equipment and tasks at your site. Referencing a standard does not mean the organization that publishes it has reviewed or endorsed this course.
Who This Course Is For
Audience: Facilities and emergency response staff working near lithium-ion battery installations.

Frequently Asked Questions
What is thermal runaway?
Thermal runaway is a chain reaction inside a battery cell where rising temperature causes reactions that release more heat. The cell can vent flammable and toxic gases and may ignite. In a battery module, heat can spread to neighboring cells.
How is a lithium-ion incident different from a lead-acid battery incident?
Lead-acid batteries mainly pose hydrogen gas, electrolyte and electrical hazards. Lithium-ion batteries can go into self-sustaining thermal runaway, release large amounts of flammable gas quickly and reignite. Early detection and response planning are different as a result.
What should staff do if a lithium-ion battery alarm activates?
Follow the facility's emergency procedure: evacuate the area if required, notify the fire department and site management, and avoid entering a room that may contain flammable gas. The course's response coordination module covers how to prepare these procedures.
