|Warning|H319 (100%): Causes serious eye irritation [Warning Serious eye damage/eye irritation]|P264, P280, P305+P351+P338, and P337+P313|Aggregated GHS information provided by 566 companies from 3 notifications to the ECHA C&L Inventory.

The inhalation of smoke from a fire involving this chemical is dangerous. Extinguish fires with a dry chemical, carbon dioxide, foam or halon extinguisher. A water spray should not be used to extinguish fires involving this chemical. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should store this material at ambient temperatures. (NTP, 1992)

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

SODIUM LIGNOSULFONATE IN AQ SOLN WAS EASILY DEGRADED BY GAMMA-IRRADIATION [(60)CO] IN PRESENCE OF OXYGEN. RATE OF DISAPPEARANCE WAS ACCELERATED IN NITROUS OXIDE SATURATED SOLN.

MEDICATION (VET): HOURLY ORAL ADMIN OF 500 MG SODIUM LIGNOSULFONATE INHIBITED PEPSIN IN GASTRIC JUICE OF 3 FEMALE MONGREL DOGS WITH TOTAL GASTRIC FISTULAS. IT MAY BE USEFUL IN TREATMENT OF PEPTIC ULCER.|MEDICATION (VET): EFFECTIVE AGAINST HERPES SIMPLEX TYPE I & II OF HUMAN CELL LINES IN CULTURE & AGAINST TYPE I & II IN VAGINAL INFECTIONS IN GUINEA PIGS & MICE.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
