Sour crude oil hazards
Region V's current interest in the hazards associated with gauging tanks containing sour crude oils stems from a fatality which occurred in Michigan in March of 1988. While attempting to gauge a tank containing sour crude oil, hydrogen sulfide rich vapors from the head space of the tank were released into the breathing zone of an employee immediately rendering him unconscious with death following shortly thereafter. H 2 S is a recognized hazard in the oil and gas industry, where it may be emitted or released during exploration, development, extraction, treatment and storage, transportation (i.e., pipeline and rail), and refining (USEPA, 1993), but it can also be of significant concern in oil spills involving sour crude. Often, sour crude oil is processed into heavy oil like diesel and fuel oil, rather than gasoline, to decrease processing expenses. For safety reasons, stabilization of sour crude oil must happen before being transported by oil tankers. Stabilization requires the removal of the hydrogen sulfide gas. Hydrogen Sulfide (H2S) is a toxic and deadly gas that is often present in crude oil (sour crude) and condensate. Even small amounts of H2S presents a health risk to personnel transporting the sour crude oil and condensate as well as pedestrians in case of accidents.
The Basics of Crude Oil Classification. Liquid petroleum pumped from oil wells is called “crude” or "crude oil.". Composed predominantly of carbon, crude oil contains approximately 84 to 87 percent carbon and 11 to 13 percent hydrogen. Crude oil also contains varying amounts of oxygen, sulfur, nitrogen, and helium.

FIRST AID MEASURES Inhalation (Breathing) Move the exposed person to fresh air. If not breathing, clear airways and give artificial respiration. If breathing is difficult, humidified oxygen should be administered by qualified personnel. The primary and essential difference between regular crude oil and "sour" crude oil is the presence of a gas known as hydrogen sulfide (H2S). In very low concentrations, less than 1 part of gas in a million parts of air. (<1 ppm), it has a characteristic odor like that of rotten eggs. In high concentrations, it has other important characteristics.

Concern with. I'm working on a 16 carbon steel pipeline that transfer crud oil at 90°C. This Crude Oil has the following characteristics: Specific gravity at 35°C (sour) contains hydrogen sulfide. 2. Hazard Identification Crude oil (sour) is extremely flammable and can cause eye, skin, gastrointestinal, and respiratory irritation. Inhalation may cause dizziness, nausea, or headache. More serious health effects can occur if crude oil is inhaled or swallowed. Crude oil (sour) may contain variable amounts of benzene and N-Hexane. Crude Oil Sour . Synonyms: Crude Petroleum . 1.2. Intended Use of the Product. A natural product derived from various oil production fields primarily consisting of a complex combination of paraffinic and aromatic hydrocarbons and small amounts of nitrogen and sulfur compounds. 1.3. Name, Address, and Telephone of the Responsible Party. Customer . Hess Tower The majority of the sulfur in crude oil occurs bonded to carbon atoms, with a small amount occurring as elemental sulfur in solution and as hydrogen sulfide gas. Sour oil can be toxic and corrosive, especially when the oil contains higher levels of hydrogen sulfide, which is a breathing hazard.
