Composition/Information on Ingredients Ingredient CAS No Percent Hazardous --------------------------------------- ------------ ------- --------- 4-Diphenylamine-4-sulfonic Acid Barium 6211-24-1 100% Yes Salt 3. Hazards Identification Emergency Overview -------------------------- CAUTION! MAY BE HARMFUL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN. MAY CAUSE IRRITATION TO SKIN, EYES, AND RESPIRATORY TRACT. MAY AFFECT BLOOD SYSTEM. Potential Health Effects ---------------------------------- The health effects of this substance have not been thoroughly investigated. The health hazards are expected to parallel those for diphenylamine, CAS number 122-39-4 (a comparable compound). Inhalation: Inhalation of dusts of a comparable compound may cause irritation to the respiratory tract and cause moderate systemic effects such as methemoglobinemia by absorption. Ingestion: Comparable compounds are moderately toxic by ingestion and can cause blood circulation problems. Skin Contact: Comparable compounds cause irritation and may be absorbed through the skin. Eye Contact: May cause irritation. Chronic Exposure: No information found. Aggravation of Pre-existing Conditions: No information found. 4. First Aid Measures Procedures that parallel those of diphenylamine (CAS #122-39-4) will be discussed. Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty. Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention. Skin Contact: Remove any contaminated clothing. Wash skin with soap or mild detergent and water for at least 15 minutes. Get medical attention if irritation develops or persists. Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately. 5. Fire Fighting Measures Fire: Not considered to be a fire hazard. Explosion: Not considered to be an explosion hazard. Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire. Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode. 6. Accidental Release Measures Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust. 7. Handling and Storage Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. 8. Exposure Controls/Personal Protection Airborne Exposure Limits: None established. For Diphenylamine (CAS #122-39-4), a comparable compound: ACGIH Threshold Limit Value (TLV): 10 mg/m3 (TWA). Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details. Personal Respirators (NIOSH Approved): If the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. An OV/DM respirator may be preferable when odor is a problem. Skin Protection: Wear protective gloves and clean body-covering clothing. Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area. 9.
