What does brake fluid do to your body? This innocuous-looking liquid plays a crucial role in your car’s braking system, but its toxicity can pose a serious threat to human health.
Brake Fluid Composition
Brake fluid is a hydraulic fluid composed of polyglycol ethers and borate esters. These chemicals provide the fluid with its high boiling point and lubricity, allowing it to withstand the extreme temperatures and pressures generated during braking.
Toxicity of Brake Fluid
Despite its essential function, brake fluid is highly toxic. It contains ethylene glycol, a known poison that can cause severe damage to the kidneys, liver, and nervous system. Even small amounts of brake fluid can be harmful if ingested or absorbed through the skin.
Routes of Exposure
Brake fluid exposure can occur through several routes:
- Ingestion: Swallowing brake fluid, even in small amounts, can be fatal.
- Inhalation: Brake fluid vapors can be inhaled during brake repairs or when handling contaminated brake lines.
- Skin contact: Direct contact with brake fluid can cause skin irritation, burns, and absorption of toxins through the skin.
Symptoms of Brake Fluid Exposure
The symptoms of brake fluid exposure vary depending on the route of exposure and the amount ingested or absorbed. Common symptoms include:
- Nausea and vomiting
- Abdominal pain
- Diarrhea
- Headache
- Dizziness
- Blurred vision
- Seizures
- Coma
Long-Term Effects of Brake Fluid Exposure
Chronic exposure to brake fluid can lead to severe health complications, including:
- Kidney failure
- Liver damage
- Nervous system disorders
- Reproductive problems
- Cancer
First Aid for Brake Fluid Exposure
If you suspect brake fluid exposure, follow these first aid steps:
- Ingestion: Do not induce vomiting. Rinse the mouth with water and seek immediate medical attention.
- Inhalation: Move the person to fresh air and provide oxygen if necessary.
- Skin contact: Wash the affected area with soap and water for at least 15 minutes. Remove contaminated clothing and seek medical attention if irritation persists.
Prevention of Brake Fluid Exposure
To prevent brake fluid exposure, follow these precautions:
- Wear gloves and protective clothing when handling brake fluid.
- Avoid breathing brake fluid vapors.
- Keep brake fluid out of reach of children and pets.
- Dispose of used brake fluid properly at a hazardous waste facility.
Warning Signs of Brake Fluid Leaks
A brake fluid leak can indicate a serious problem with your car’s braking system. Look for these warning signs:
- Low brake fluid level in the master cylinder
- Spongy or soft brake pedal
- Leaking brake lines or hoses
- Vehicle pulling to one side when braking
What to Do if You Suspect a Brake Fluid Leak
If you suspect a brake fluid leak, do not drive the car. Contact a qualified mechanic immediately to have the leak repaired.
