OLOA 59766

Move the exposed person to fresh air. Get medical attention if coughing or respiratory discomfort occurs. If exposure 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. Hydrogen sulfide: irritation of the eyes, nose, and throat. Moderate levels: headache, dizziness, nausea, vomiting, coughing, and difficulty breathing. Higher levels: shock, convulsions, coma, and death.

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: Contact with the skin may cause an allergic skin reaction. Symptoms may include pain, itching, discoloration, swelling, and blistering.

No specific first aid measures are required. As a precaution, remove contact lenses, if worn, and flush eyes with water.

Symptoms: Not expected to cause prolonged or significant eye irritation. Hydrogen sulfide: irritation of the eyes.

No specific first aid measures are required. 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. Clean up spill as soon as possible, observing precautions in Exposure Controls/Personal Protection.

Contain release to prevent further contamination of soil, surface water or groundwater.

applying non-combustible absorbent materials or pumping

Materials: non-combustible absorbent materials

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.

The maximum short-term (<2 week(s)) storage temperature is 66°C. The maximum long-term (>2 week(s)) storage temperature is 45°C.

Wash thoroughly after handling.

Bonding and grounding may be necessary. Review all operations which have the potential of generating and accumulating an electrostatic charge and/or a flammable atmosphere and use appropriate mitigating procedures.

Use in a well-ventilated area.

Selection of chemical protective clothing should be performed by an Occupational Hygienist or Safety Professional and be based upon applicable standards (ASTM F739 or EN 374). Using chemical PPE depends upon operations conducted and may include chemical gloves, boots, chemical apron, chemical suit, and complete facial protection. Refer to PPE manufacturers to obtain breakthrough time information to determine how long PPE can be used before it needs to be replaced. Unless specific glove manufacturer data indicates otherwise, the below table is based upon available industry data to assist in the glove selection process and is intended to be used as reference only. Chemical Glove Material: Butyl (0.35 mm, 5 minutes), Neoprene (1.4 mm, 30 minutes), Nitrile (0.8 mm, 240 minutes), Polyvinyl Chloride (PVC) (1.5 mm, 30 minutes), Viton Butyl (0.3 mm, 120 minutes).

Wear protective equipment to prevent eye contact. Selection of protective equipment may include safety glasses, chemical goggles, face shields, or a combination depending on the work operations conducted.

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 chemical personal protective equipment (PPE) to prevent skin contact. Selection of chemical protective clothing should be performed by an Occupational Hygienist or Safety Professional and be based upon applicable standards (ASTM F739 or EN 374). Using chemical PPE depends upon operations conducted and may include chemical gloves, boots, chemical apron, chemical suit, and complete facial protection.

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