SECTION 2 - HAZARD IDENTIFICATION
Appearance & Odor: Amber to brown liquid. Slight hydrocarbon odor.
Primary Routes of Exposure: Skin, Eyes and Respiratory tract.
Health Hazard Warnings: DANGER! Corrosive. Causes severe burns to eyes and skin. Eye contact may cause
blindness. Harmful if swallowed or inhaled. Vapors are irritating. Exothermic reaction with water, alcohols and
strong alkalis.
Inhalation: Inhalation can cause coughing, choking, and variable symptoms of headache, dizziness, and weakness.
Pulmonary edema (accumulation of fluids in the lungs) with tightness in the chest, air hunger, dizziness, frothy
sputum, and cyanosis may follow, 6 to 8 hour latent period. Physical findings may include moist rales and low blood
pressure. Prolonged or repeated overexposure to toluene can cause kidney and liver damage.
Skin Contact: Can cause severe burns to skin. Material is extremely destructive to tissue.
Eye Contact: Can cause burns unless immediately and thoroughly flushed with water. May cause permanent eye
damage. Symptoms include pain, tearing, and photophobia (sensitivity to light).
Ingestion: Material is harmful if swallowed. Severe burning pain in the mouth, pharynx and abdomen, followed by
by vomiting and diarrhea of dark precipitated blood. Choking will occur due to swelling of the throat.

SECTION 4 - FIRST AID MEASURES
Eyes: Immediately flush eyes with water for 15-20 minutes. Hold eyelids apart and roll eyes up and down to assure
complete washing. Seek immediate medical attention.
Skin: Thoroughly flush the affected area with plenty of water while removing contaminated clothing and equipment.
Wash with water for at least 15 minutes. Apply sterile bandages to affected area and treat as a thermal burn. Seek
medical attention.

SECTION 4 - FIRST AID MEASURES (CONT.)
Inhalation: Immediately move the patient to fresh air and call a physician. If breathing is difficult, give oxygen. If not
breathing, begin artificial respiration.
Ingestion: Call a physician. If swallowed, call a physician immediately. Only induce vomiting at the instruction of a
physician. Never give anything by mouth to an unconscious person.
Other Specific Instructions: In the event of exposure, seek medical attention immediately. Do not give chemical
antidotes unless directed to do so by the physician. Treat for shock.
SECTION 5 - FIRE FIGHTING MEASURES
Flash Point: > 200 oC Auto Ignition: No data available
Explosive Limits; UEL/LEL: No data available
Extinguishing Agents: Use water spray, dry chemical, carbon dioxide, or foam extinguishing agents.
Fire & Explosion Hazards: As in any fire prevent human exposure to fire, smoke, fumes or products of combustion.
Firefighters should wear recommended exposure control equipment including a self-contained breathing apparatus.
Cool containers with water spray that are exposed to flames. Avoid placing a solid stream of water on spilled
material.
Hazardous Combustion Products: Thermal decomposition producers oxides of carbon and sulfur.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
Personal Protective Equipment: Appropriate protective equipment must be worn when handling a spill of NAXCAT庐
MOD ACID-35. See Section 8 - Exposure Control, for recommendations.
Spill or Leak Information: Absorb spill material with an inert material (i.e. vermiculite, soil, etc.). Sweep or scoop
material into a container for disposal. Flush spill area with plenty of water to a chemical sewer. Collect water for
proper disposal. Prevent discharge to bodies of water.
SECTION 7 - HANDLING AND STORAGE
Handling Conditions: Prevent all skin and eye contact. Use local exhaust ventilation to prevent exposure to vapors
and mists. Emptied container may retain product residues. Follow all warnings and precautions even after container
is emptied.
Storage Conditions: Keep container tightly closed when not in use. Store in cool and well ventilated area. Steel is
corroded by sulfonic acids and is not recommended for prolonged storage at elevated temperatures since iron and
color contamination could result. Dilution with water may increase the corrosivity of the acid. Material will absorb
moisture.
SECTION 8 - EXPOSURE CONTROL
1.0 mg/m3; TWA Sulfuric acid
Exposure Limits:
50 ppm - skin; TWA Toluene
100 ppm; TWA Xylene
Eye Protection: Use chemical splash goggles. Wear face shield when transferring material.
Skin Protection: Skin contact with material should be minimized through the use of suitable impervious gloves. Butyl
rubber or neoprene gloves are recommended. Use chemical resistant protective clothing or apron when handling
this material.

SECTION 8 - EXPOSURE CONTROL (CONT.)
Respiratory Protection: Use a NIOSH/MSHA approved full-facepiece air-purifying respirator with organic vapor/acid
gas cartridge with a dust/mist prefilter. If exposure conditions warrant, wear a self-contained breathing apparatus in
the positive pressure mode.
Ventilation: Good local exhaust ventilation should be provided.
Other Protective Equipment: Safety showers and eye wash stations where material is being handled. Wash hands
and face before eating, using tobacco products or using the washroom. Smoke or eat only in designated areas.
Take a warm shower and change clothing daily. Clothing and shoes used while handling this material should not be
worn or taken away from the workplace.
