What is the primary hazard associated with working on or near batteries?

The primary hazard associated with working on or near batteries includes the risk of acid burns, electric shock, and explosion due to flammable gases. Batteries, especially lead-acid types commonly found in vehicles, contain sulfuric acid, which can lead to severe chemical burns upon contact with skin. Additionally, when batteries are improperly handled, they can produce hydrogen gas, which is highly flammable and can lead to explosions if ignited.

Furthermore, electric shock is a significant concern, particularly with high-voltage batteries found in hybrid and electric vehicles. Touching terminals or dealing with damaged batteries can expose workers to electric shock, which can be dangerous or even fatal. Recognizing these hazards underscores the importance of proper safety protocols, personal protective equipment, and training when working with batteries in automotive contexts.

Understanding these risks promotes safer work practices and helps prevent accidents in automotive environments.
