OLOA 54510

Move the exposed person to fresh air. If exposed to hydrogen sulfide (H2S) gas is possible during an emergency, wear an approved, positive pressure air-supplying respirator. Move the exposed person to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get immediate medical attention.

Symptoms: Coughing, respiratory discomfort, respiratory irritation, headache, dizziness, nausea, vomiting, shock, convulsions, coma, and death (related to H2S).

Wash skin with water immediately and remove contaminated clothing and shoes. Get medical attention if any symptoms develop. To remove the material from skin, apply a waterless hand cleaner, mineral oil, or petroleum jelly. Then wash with soap and water. Discard contaminated clothing and shoes or thoroughly clean before reuse.

Symptoms: Allergic skin reaction. Symptoms may include pain, itching, discoloration, swelling, and blistering.

Remove contact lenses, if worn, and flush eyes with water.

Symptoms: Not expected to cause prolonged or significant eye irritation.

Do not induce vomiting. As a precaution, get medical advice.

Symptoms: Not expected to be harmful if swallowed.

Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames.

This material will burn although it is not easily ignited.

For fires involving this material, do not enter any enclosed or confined fire space without proper protective equipment, including self-contained breathing apparatus.

Stop the source of the release if you can do it without risk. Contain release to prevent further contamination of soil, surface water or groundwater.

Do not get in eyes, on skin, or on clothing. Do not taste or swallow. Do not breathe gas. Wash thoroughly after handling. Toxic quantities of hydrogen sulfide (H2S) may be present in storage tanks and bulk transport vessels. Persons opening or entering these compartments should first determine if H2S is present. Do not attempt rescue of a person over exposed to H2S without wearing approved supplied-air or self-contained breathing equipment.

Storage temperatures for up to 2 weeks should not exceed 66°C (150°F). The recommended long-term (2 weeks or more) storage temperature is ambient to 45°C (113°F) maximum.

Wash thoroughly after handling.

Review all operations which have the potential of generating and accumulating an electrostatic charge and/or a flammable atmosphere (including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations) and use appropriate mitigating procedures.

Use in a well-ventilated area.

Suggested materials for protective gloves include: Nitrile Rubber, Silver Shield, Viton.

No special eye protection is normally required. Where splashing is possible, wear safety glasses with side shields as a good safety practice.

No respiratory protection is normally required. If material is heated and emits hydrogen sulfide, determine if airborne concentrations are below the occupational exposure limit for hydrogen sulfide. If not, wear an approved positive pressure air-supplying respirator. For more information on hydrogen sulfide, see Chevron SDS No. 301. If user operations generate an oil mist, determine if airborne concentrations are below the occupational exposure limit for mineral oil mist. If not, wear an approved respirator that provides adequate protection from the measured concentrations of this material. For air-purifying respirators use a particulate cartridge.

Wear protective clothing to prevent skin contact. Selection of protective clothing may include gloves, apron, boots, and complete facial protection depending on operations conducted.

See relevant Community environmental protection legislation or the Annex, as applicable.

This material is considered stable under normal ambient and anticipated storage and handling conditions of temperature and pressure.

May react with strong acids or strong oxidizing agents, such as chlorates, nitrates, peroxides, etc.

Hazardous polymerization will not occur.

Do not exceed handling and storage temperatures listed in SDS Section 7 (Handling and Storage).

Not applicable

Alkyl Mercaptans (See Section 7), Hydrogen Sulfide (See Section 7)

Use material for its intended purpose or recycle if possible.

This material, if it must be discarded, may meet the criteria of a hazardous waste as defined by international, country, or local laws and regulations.
