Is coolant dangerous?
Yes, coolant is dangerous because it contains toxic substances that are harmful to humans, animals, and the environment. Ethylene glycol, in particular, can cause serious poisoning if swallowed, and skin contact, inhalation, or release into the environment also pose risks. Coolant disposal must therefore comply with chemical waste standards and legislation.
Coolant is essential for cooling and protecting engines and machinery, but if used or disposed of incorrectly, it can cause serious damage to health and the environment. This article explains why coolant is dangerous, its environmental impact, and how to store and dispose of it safely in accordance with applicable environmental regulations.
What is in coolant?
Coolant consists of a mixture of water, glycol (usually ethylene or propylene glycol), and additives such as inhibitors for corrosion, oxidation, and foaming. This combination maintains engine temperature but also makes coolant chemically aggressive.
Over time, the fluid ages: the additives break down, and heavy metals, oil residues, and acids can form. These breakdown products are toxic and must not be released into the environment.
Why is coolant dangerous?
Coolant is dangerous because it contains substances that are toxic if swallowed or come into contact with skin. Ethylene glycol, in particular, is highly harmful to humans and animals—just a few milliliters can be fatal if ingested. Furthermore, when burned or spilled, coolant can contaminate surface water, soil, and air quality.
Propylene glycol is a safer alternative and is sometimes used in applications involving human contact (such as refrigeration equipment in the food industry), but this variant also falls under the category of chemical waste once it is contaminated.
Therefore, used coolant is always considered hazardous waste and must not be disposed of in the sewer or as residual waste.
The environmental impact of coolant
The environmental impact of coolant is significant when disposed of incorrectly or spilled. Glycol and additives biodegrade, but this process consumes significant oxygen in the water. This creates oxygen deficiency, which suffocates fish and other aquatic organisms.
In addition, heavy metals and chemicals from coolants can leach into the soil and contaminate groundwater. This not only affects ecosystems but also drinking water quality.
By having coolant collected and recycled correctly through a certified processor such as Chemisch Afval Nederland, you prevent these harmful substances from entering the environment.
Coolant poisoning
Coolant poisoning occurs when ethylene glycol or propylene glycol is swallowed, inhaled, or absorbed through the skin. Ethylene glycol, in particular, is extremely dangerous: it converts into toxic acids in the body, leading to kidney failure, loss of consciousness, or even death.
Symptoms of coolant poisoning:
These are the symptoms of coolant poisoning:
- Nausea and vomiting
- Dizziness and disorientation
- Accelerated heart rate
- Breathing problems
- Decreased urine production or kidney failure
Immediate medical attention is required for people or animals that may have ingested coolant.
Contact your GP, veterinarian or call 112 immediately. Never try to induce vomiting yourself.
Risks of incorrect disposal or storage
Incorrect storage or disposal of coolant can lead to:
- Soil and surface water pollution: Glycol biodegrades, but this process consumes oxygen, causing oxygen deficiency for fish and aquatic life.
- Harm to animals and plants: Ethylene glycol tastes sweet and is therefore attractive to pets, but even small amounts are fatal.
- Workplace health hazards: Vapors or splashes may cause skin and eye irritation. In enclosed spaces, vaporization may cause respiratory problems.
- Fines for violations of environmental legislation: the Environmental Management Act and the Activities Decree oblige companies to store and dispose of hazardous waste correctly.
Even small amounts of coolant leaking down the drain or into the ground can cause long-term environmental damage.
How do you recognize dangerous or outdated coolant?
Old or contaminated coolant is often cloudy, dark brown, or gray. Sometimes an oily film or a milky haze forms on the surface. A sweet, chemical odor may also develop: this is a sign of glycol degradation.
As soon as you notice these signs, replacement is necessary. The fluid should then be disposed of as chemical waste.
How can you safely store and dispose of coolant?
Storage:
- Use UN-approved drums or jerrycans with tight-fitting lids.
- Place these on a drip tray to catch spills.
- Clearly label “Coolant – Hazardous Waste”.
- Store in a cool, ventilated place away from heat sources or direct sunlight.
Disposal:
- For businesses: Always have coolant collected by a certified collector. Read more here drain glycol.
- For private individuals: Take it to a recycling center, waste disposal stations or chemical waste collection point near you.
Frequently Asked Questions
How dangerous is coolant?
Coolant is extremely dangerous when misused or disposed of. Even small amounts can be harmful to humans, animals, and the environment. Ethylene glycol, in particular, is toxic and must always be disposed of professionally.
Is coolant poisonous?
Yes, coolant is toxic to humans, animals, and the environment. Ethylene glycol, in particular, is highly harmful if ingested and can be fatal even in small doses. The coolant has a sweet odor and taste, making it dangerously attractive to animals and children.
Is coolant dangerous to people and animals?
Yes, coolant is dangerous and toxic if swallowed, inhaled, or if it comes into contact with the skin. Ethylene glycol, in particular, is extremely harmful to humans, pets, and wildlife. Even small amounts can be fatal. If you suspect coolant poisoning, always contact your doctor or veterinarian immediately.
Is coolant poisonous to dogs?
Yes, coolant is highly toxic to dogs. Even one teaspoon of ethylene glycol can be fatal for a medium-sized dog. It causes kidney failure and neurological damage. Clean up spilled coolant immediately and never allow your dog near spilled liquids or open containers. Always contact your veterinarian immediately!
Is coolant poisonous to cats?
Yes, coolant is highly toxic to cats. Even a few drops can cause serious poisoning or death. Cats can ingest the fluid through their paws or fur. Always clean up spills immediately and never leave a container open. Always contact your veterinarian immediately!
Is coolant poisonous to pets?
Yes, coolant is toxic to pets such as dogs, cats, rabbits, chickens, and rodents. The sweet taste of ethylene glycol makes it especially dangerous. Always keep coolant out of reach of animals and contact your doctor immediately if you suspect ingestion.
Is all coolant dangerous?
Yes, all types of coolant contain chemicals. Propylene glycol is slightly less toxic than ethylene glycol, but must still be treated as hazardous waste.
Can I dispose of coolant myself?
No, coolant should not be disposed of in residual waste, down the sink, drain, toilet, or sewer. Always take it to the recycling center or have it collected by a certified collector.
Is it dangerous if your coolant leaks?
Yes, leaking coolant is dangerous. The fluid can cause slippery conditions, release fumes, and leak toxic substances into the ground. Clean up any leaks immediately and have the residue professionally removed.
Can coolant do any harm?
Yes, coolant can be harmful if used or disposed of incorrectly. It is toxic, environmentally harmful, and can have serious consequences for humans, animals, soil, and water if spilled, contacted by skin, inhaled, or ingested.
Is coolant poisonous to the touch?
Yes, coolant is toxic to the touch. Prolonged contact with skin can cause irritation, redness, or burns. Always wear gloves and avoid contact with eyes or mouth.
Is coolant dangerous to inhale?
Yes, coolant is dangerous if inhaled. The vapors of ethylene glycol, in particular, can irritate the respiratory tract, eyes, and mucous membranes. In poorly ventilated areas, prolonged exposure can lead to headaches, dizziness, nausea, and breathing difficulties.
When working with coolant, good ventilation is essential, and vapors should be avoided as much as possible. Wear protective clothing and clean up spills immediately.
What happens if I dispose of coolant incorrectly?
Improper disposal can lead to environmental pollution, damage to facilities, and hefty fines. Companies are legally obligated to dispose of hazardous waste correctly.
