What PPE should be worn when responding to a lithium battery incident?

In the context of responding to a lithium battery incident, wearing full protective gear and a Self-Contained Breathing Apparatus (SCBA) is critical due to the potential hazards associated with lithium batteries. When lithium batteries are damaged, they can release flammable gases and chemicals, which can lead to combustion or explosions.

Full protective gear is designed to provide a barrier against chemical splashes, thermal exposure, and other potential physical hazards encountered in such scenarios. SCBA not only offers respiratory protection from harmful fumes and gases but also ensures that responders have a reliable air supply in an environment that might be oxygen-deficient or contaminated. This level of protection is essential for ensuring the safety of personnel who may face unknown risks when dealing with these types of incidents.

While the other options do offer some degree of protection, they do not provide the comprehensive safety measures required for a situation involving lithium batteries, where the volatility and hazardous nature of the materials necessitate the highest level of protective equipment.
