Coolants containing ethylene glycol, while effective, tend to be toxic and pose risks to both humans and animals if accidentally ingested.

Coolants containing ethylene glycol, while effective, tend to be toxic and pose risks to both humans and animals if accidentally ingested. In contrast, nontoxic alternatives often use propylene glycol, making them safer for handling and spills. Proper handling involves using gloves and avoiding direct contact with skin, as well as ensuring that the coolant is stored securely away from children and pets.

Disposal should never be done down drains or onto soil; instead, used coolant must be taken to recycling centers or hazardous waste facilities where it can be processed safely, preventing contamination of water sources and soil. Keeping these aspects in mind helps maintain a safer working environment and contributes to protecting the surrounding nature during vehicle maintenance.
