Important Notes and Precautions on Methacrylonitrile Handling and Use

Be sure to read the complete MSDS before any handling or use of methacrylonitrile.

DO NOT USE METHACRYLONITRILE IN ANY APPLICATION WHICH MAY INVOLVE OR RESULT IN ITS DIRECT CONTACT WITH FOOD OR WITH THE HUMAN BODY.

HAZARD IDENTIFICATION:

EMERGENCY OVERVIEW
Clear, colorless liquid. Highly flammable liquid with a flash point 1.1°C(C.C.) .Vapor can form an explosive gaseous mixture with air.

POTENTIAL HEALTH EFFECTS
Primary Routes of Exposure
EYE: Contact causes eye irritation or eye injury.
SKIN: Contact causes skin irritation or skin injury.
INHALATION: Harmful if inhaled.
INGESTION: Harmful if swallowed.
Extended exposure to the vapor may cause headache, dizziness, nausea, feeling of exhaustion.

CARCINOGENICITY
Not listed by ACGIH, IARC, NIOSH, NTP or OSHA

OTHER CHRONIC TOXICITY: Not available
Note:
Can be absorbed through the skin. Exposure may cause delayed health effects. Symptoms may first be felt after two to four hours of exposure and worsen thereafter. Inhalation of vapor in relatively high concentrations may occur without notice, as odor is only slight.

ACUTE TOXICITY: Oral LD50(rat) 25-50mg/kg

FIRST AID MEASURES:

EYE CONTACT:
Immediately flush affected eye(s) gently with large quantity of clean water for 15 minutes. Seek immediate medical attention.

SKIN CONTACT:
Immediately remove contaminated clothing and shoes and wash affected area thoroughly with soap and water. Seek immediate medical attention.

INHALATION:
  • Remove victim to fresh air immediately. Keep victim at rest, and warm with blankets or other covering. Seek immediate medical attention.
  • If victim is not breathing, give artificial respiration immediately.
  • If victim is breathing with difficulty, administer oxygen.

INGESTION
  • If victim is conscious, induce vomiting with lukewarm water or other appropriate means, and seek immediate medical attention. If victim is unconscious, seek immediate medical attention but do not give any liquid or otherwise induce vomiting.

FIRE FIGHTING MEASURES:

FLAMMABLE PROPERTIES
Flash point, test method: 34°F(1.1°C), C.C.
Flammable limits: 2.1 to 11.6% by volume
Flammability: Flammable liquid
Spontaneous combustibility: None
Reactivity with water: None
Oxidizability: None
Self-reactivity: In absence of inhibitor, may undergo spontaneous exothermal polymerization leading to fire or explosion.

EXTINGUISHING MEDIA:
Dry chemical powder, foam, carbon dioxide and dry sand.

FIRE FIGHTING INSTRUCTIONS:
  • Hazardous gas will be produced during fire. Perform fire-fighting from the windward side of fire, wearing full fire-fighting gear (full bunker gear) and respiratory protection (self-contained breathing apparatus).
  • Do not use water for fire-fighting.
  • Fire may be extinguished by smothering in the above extinguishing media.
  • For fire occurring inside tank, extinguish by filling tank with the extinguishing media to isolate the contents of the tank from air, while cooling the outside of the tank with water jet.

HANDLING AND STORAGE

HANDLING
  • Avoid contact with eyes, skin and clothing.
  • Avoid breathing vapor, mist and gas.
  • Keep away from static electricity, spark, and other ignition sources.
  • Keep away from oxidizing materials and other incompatible materials.
  • Always keep container closed airtight, and provide local exhaust ventilation.
  • Avoid tumbling, dropping, dragging or other rough handling of full or emptied container, both before and after use.
  • Wash hands and any other bare skin area thoroughly immediately after handling or contact, and remove any contaminated clothing.
STORAGE
  • Electrical equipment must be of explosion-proof construction and grounded.
  • Keep away from direct sunlight to prevent polymerization reaction.
  • Store in ventilated, cool dark place, with the container cap facing upward. Keep under a nitrogen blanket.
  • Keep away from ignition sources, high temperature equipment such as boilers, and oxidizing materials.
  • Perform storage in compliance with all national and local regulations.
