Is WD-40 Safe for Human Use? Understanding Safety and Potential Dangers

WD-40, a common household product, is often used for its lubricating and protective properties. However, many people wonder about the safety of this product when it comes to human contact. This article delves into the composition of WD-40, its potential dangers, and how to use it safely.

Composition and Safety Concerns

WD-40 is composed of a ~50:50 mixture of naphtha and light oil, such as kerosene, and approximately 2–3% of a surfactant organic acid similar to solder flux.

None of these components are suitable for human contact and should never be ingested. Common sense dictates that any chemical product that incorporates these ingredients is not meant for direct contact with the skin or consumption.

Proper Handling and Safety Measures

Read the Safety Data Sheet (MSDS) for comprehensive information on handling and potential hazards. The MSDS will detail the appropriate measures to take in the event of contact or ingestion.

WD-40 is a mild petroleum product. Proper care should be taken when using it. After application, wash your hands thoroughly, especially if you have open cuts or wounds. If you inadvertently inhale or ingest any WD-40, seek medical advice immediately. For such incidents, contact your local poison control hotline for guidance.

Rare Abscessive Reactions

For individuals with a high sensitivity to petroleum products, additional precautions may be necessary. An N95 respirator and gloves can be used to minimize exposure. However, such sensitivities are very rare. If you have experienced convulsions or a catatonic state after exposure to petroleum products, consult a healthcare professional.

Consequences of Misuse

Using WD-40 incorrectly can lead to serious consequences. Spraying it in your face or other body openings is dangerous. Attempting to burn the can can also result in an explosion. Follow the instructions on the label and use WD-40 as directed to ensure safety.

Conclusion

While WD-40 is a versatile and effective product, it is crucial to handle it with care. Understanding its composition, taking appropriate safety measures, and being aware of the risks can help prevent any potential harm.
