    What are Penetrating Oils?

    Penetrating oils are generally used to free rusted nuts, bolts, locks, joints, etc as well as to clean parts. Few products are as common across all trades as penetrating oils. Anyone required to work with rusted or corroded parts, is likely using some form of a penetrating oil.

    Examples of popular brand name penetrating oils include WD-40, Liquid Wrench, Kroil, Nuts Off, PB Blaster, CRC Knock’er Loose, Lock-ease, and 3-in-One. Many household consumers will be familiar with these products. However, in occupational settings, penetrating oils are used at a much greater scale, and are often purchased in bulk (e.g. 55-gallon drums).

    Why are Penetrating Oils Dangerous?

    Chronic exposure to penetrating oils can be dangerous because many of these products contain or once contained benzene. Benzene is a naturally occurring component of petroleum (AKA crude oil). Benzene can be found in penetrating oils because many penetrating oils are, at least in part, petroleum distillates.

    Benzene exposures can lead to numerous diseases, including:

    How Much Benzene is Present in Penetrating Oils?

    While most petroleum-based penetrating oils will contain trace levels of benzene, some products contain more benzene than others.

    Numerous factors affect the amount of benzene in any given product such as the proportion of petroleum distillate used in the product, what petroleum-distillate is used, and the refining process through which it was generated. However, relaxed corporate disclosure laws and opaque business practices have often made it difficult for consumers to determine how much benzene is present in a product.

    Benzene was eventually considered a contaminant and was removed from petroleum distillate products where possible. However, removing benzene from these products increases the cost to produce them. Unfortunately, some producers prioritized profit over safety.

    Today, most products generally contain comparatively low levels of benzene. However, historically some common products contained very dangerous levels of benzene.

    How Can Dangerous Exposures Occur?

    A dangerous exposure to benzene in a penetrating oil can occur through inhalation, ingestion, or absorption through the skin.

    Inhalation is often the primary route of exposure in industrial settings. Penetrating oils are quick to evaporate. As a result, benzene vapors can make their way into your lungs soon after the product is exposed to air. The workers in industrial settings, who in some cases have spent entire work days around uncovered barrels of these products, frequently endure some of the worst exposures. Poor ventilation in these workplace only worsened the exposures.

    Dermal exposures can be significant as well. Many former tradesmen can attest to near daily use of penetrating oils. Any cuts or scrapes on the skin gives the benzene in these products an open door into the bloodstream.

    Confidential settlement (Louisiana, 2009)
