Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: brown viscous liquid.
Danger! Causes severe eye and skin burns. Causes severe digestive and respiratory tract burns. Harmful if swallowed. Hygroscopic (absorbs moisture from the air). Corrosive to metal.
Target Organs: Eyes, skin, mucous membranes.


Potential Health Effects
Eye: Causes severe eye burns. May cause irreversible eye injury.
Skin: Causes severe skin irritation and burns.
Ingestion: Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause burns to the digestive tract.
Inhalation: May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema.
Chronic: Chronic exposure may cause effects similar to those of acute exposure.

Section 4 - First Aid Measures


Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid immediately.
Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse.
Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures


General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.

Environmental: Aquatic: Water temperature affects biodegration. The rate of sodium-C12 linear alkylbenzene sulfonic acids biodegradation in Chesapeake Bay water was max at 25-30 deg C and decreased at lower incubation temperatures. Sodium-C12 linear alkylbenzene sulfonic acids. Terrestrial: The adsorption of sodium-C12 linear alkylbenzene sulfonic acids is affected by the type of soil. The affinity of the soil for surfactants competes with microbial attack, slowing biodegradation.
Physical: No information found.
Other: The biodegradation of linear sodium alkylbenzenesulfonic acid ... by marine bacteria ... was degraded by some (unspecified) species of marine bacteria when it was present as a sole carbon source, but only when massive aeration was employed ... /Linear sodium alkylbenzenesulfonic acid. Sesquioxides such as ferric oxide, and aluminum oxide are important in the sorption of linear alkylbenzenesulfonic acid. /Linear alkylbenzenesulfonic acid.
