Because of its low volatility, harmful exposure to diesel fuel by inhalation is unlikely. Under conditions where exposure may occur, eye, nose, and throat irritation, headache, nausea, drowsiness, and dizziness are the only potential effects. This material is a skin irritant and repeated exposure to similarly refined and processed petroleum -bases materials has been shown to cause skin cancer in laboratory animals. There is no known evidence that this material causes cancer. Controls :Extreme caution must be taken to prevent sources of ignition from coming into contact with diesel fuel vapors. A 50400t no smoking and static/ignition-free zone (also referred to as an Exclusion Zone) must be maintained as further described herein. Employ dust suppression, as appropriate, and avoid contact with, and inhalation of, vapors and impacted soil/ dust. Used Waste Oils Hazard: Used waste oils are typically mixtures of used lubricating, hydraulic, and compressor oils. They also contain combustion products that may contain heavy metals (e.g., chromium, lead) and active polynuclear aromatic hydrocarbons (PAHs) and should be treated as a potential carcinogen and inhalation of their vapors should be avoided. As such, they are complex mixtures of middle to heavy petroleum-based hydrocarbons. Acute toxicity associated with exposure to this material is low. Some degree of skin irritation is possible with prolonged contact. Controls : Employ dust suppression, as appropriate, and avoid contact with, and inhalation of, vapors and impacted soil/ dust. and Hazard: Typically lead (or inorganic or elemental lead) is seen from lead - laden soil in tank excavations and along the unsurfaced shoulders of highways and other thoroughfares. Another common exposure scenario is breathing dust from lead paint during construction, remodeling, abatement, or demolition activities. Tetraethyl lead is the organic form of lead that was once an additive to gasoline and is now no longer used. Lead in its elemental form is a heavy metal at room temperature and pressure. It can combine with other elements and compounds to make pigments, binders, electrodes, and structural materials. Tetraethyl lead can be a hazard if the gasoline4rapacted soil or groundwater that workers encounter is old enough to contain significant amounts of leaded gas. The most likely exposure route is inhalation of dusts from lead in soil contaminated by old gasoline or batteries, or lead -containing paint that has either deteriorated from structures or is being sanded or demolished.
