Primary Health Hazards: Irritation due to direct skin/eye contact with the liquid and inhalation of the mist
or vapor.
Primary Route(s) of Exposure:
Ingestion:
Skin: Liquid
Inhalation: Mist, vapor
Eye:
Medical Conditions Generally Aggravated by Exposure: None identified.
Signs and Symptoms of Exposure:
Acute Health Hazards: May cause irritation to the respiratory system, eyes and skin.

4. Emergency and First-Aid Procedures
Ingestion: Not likely to occur under normal use. Can cause damage to mouth, throat, and stomach if
ingested. Do not induce vomiting. Rinse mouth out with water. Drink large amounts of water. Get
immediate medical help.
Eye Contact: Will cause irritation. Immediately flush with running water for 15 minutes including under
eyelids. Get medical help if irritation persists.
Skin Contact: May cause irritation. Repeated brief contact can cause cracking, peeling, blistering.
Remove contaminated clothes. Immediately wash affected area with soap and water. Get medical
help if irritation or burns are present after washing.
Skin Absorption: Not likely to occur with normal use.
Inhalation: May cause nose, throat, and respiratory system irritation. Remove to fresh air. Get medical

6. Accidental Release Measures
Steps to be Taken In Case Material Is Released or Spilled: Immediately notify safety and
environmental personnel. For a large spill in a clean area, dike and recover for reuse. Dispose of
contaminated material. For a small spill, mix with absorbent material and dispose. Never neutralize
spill with acid. Never neutralize spill with acid. Do not divert to an acid-containing sewer.

7. Handling and Storage
Precautions to be Taken In Handling and Storage: Avoid all contact with skin and eyes. Do not allow
potential leaks to be discharged into an acid-containing sewer. Depending on specific handling and
storage methods, dissolved total reduced sulfur compounds including hydrogen sulfide may be
released and into a vapor space in potentially hazardous amounts.
8. Exposure Control Measures, Personal Protection
Personal Protective Equipment:
RESPIRATORY PROTECTION 鈥? A NIOSH-approved respirator for dust/mist/organic vapors/acid gases
is recommended if exposure levels warrant. If firefighting you should use an SCBA in pressure
demand mode.
EYE PROTECTION 鈥? Chemical goggles are recommended.
PROTECTIVE GLOVES 鈥? Rubber gloves are recommended.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT 鈥? Apron, boots, face shield, or rubber suit may be
needed when handling large amounts.
WORK/HYGIENE PRACTICES 鈥? Eyewash stations and safety showers should be readily accessible if a
splash hazard exists.
Ventilation:
LOCAL EXHAUST 鈥? Provide local exhaust as needed.
MECHANICAL (GENERAL) 鈥? Provide general ventilation in processing and storage areas.
SPECIAL 鈥? Self-contained breathing apparatus (SCBA) recommended when fighting fire.
OTHER 鈥? Emergency eye wash fountain and quick drench shower if a splash hazard exists.
