SECTION 2 - HAZARDS IDENTIFICATION
Emergency Overview
Gray. Liquid. May cause drowsiness, weakness, and fatigue. Vapor and/or mist may irritate nose and throat.
May cause moderate irritation to the respiratory system. May cause allergic respiratory sensitization. Move to
fresh air. If required, artificial respiration or administration of oxygen can be performed by trained personnel.
Leave area to breathe fresh air. Avoid further overexposure. If symptoms persist, get medical attention.
Acute Potential Health Effects/ Routes of Entry
Inhalation May cause drowsiness, weakness, and fatigue. Vapor and/or mist may irritate nose and
:
throat. May cause moderate irritation to the respiratory system. May cause allergic
respiratory sensitization.
Eyes Vapor and/or mist may cause eye irritation.
:
Ingestion May cause irritation to the mouth, throat and stomach. May cause gastrointestinal
:
irritation, nausea, and vomiting.
Skin May cause sensitization resulting in irritation, itching and redness.
:
Aggravated Medical Conditions
Pre-existing eye, skin, liver, kidney, and respiratory disorders may be aggravated by exposure.
Chronic Health Effects
Overexposure may cause dermatitis, asthma, skin and respiratory sensitization and decreased lung function.
Repeated overexposure to vapors and/or material may injure the liver, kidneys and respiratory system unless
suitable engineering controls and/or personal protective equipment are used. Prolonged or repeated
contact/exposure to aromatic petroleum distillates may cause defatting, drying, and irritation of the skin,
dermatitis, and central nervous system (CNS) effects. Inhalation of crystalline silica (quartz) can cause cancer
based on animal data, and IARC concludes sufficient evidence in humans (Group 1). Prolonged and repeated
overexposure to free crystalline silica dust above the TLV level may cause scarring of the lungs with cough and
shortness of breath. A delayed lung injury, silicosis may result from breathing free silica. A long-term NTP study
showed that oral exposure to toluene diisocyanate (TDI) caused cancer in rats and mice. A lifetime inhalation
study sponsored by the International Isocyanate Institute did not show carcinogenic activity in rats. May cause
allergic skin and respiratory sensitization. Fillers are encapsulated and not expected to be released from
product under normal conditions of use.
Target Organs: Eye, Lung, Liver, Kidney, Skin, Nerve

SECTION 4 - FIRST AID MEASURES
Get immediate medical attention for any significant overexposure.
Inhalation : Move to fresh air. If required, artificial respiration or administration of oxygen can be
performed by trained personnel.Leave area to breathe fresh air. Avoid further
overexposure. If symptoms persist, get medical attention.
Eye contact : Flush with water for at least 15 minutes while holding eye lids apart. Get medical
attention immediately.
Skin contact : Wash area of contact thoroughly with hand cleaner followed by soap and water. If
irritation, rash or other disorders develop, get medical attention immediately.
Ingestion : Do not induce vomiting unless advised by a physician. Call nearest Poison Control
Center or Physician immediately.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
Use appropriate protective equipment. Avoid contact with material. Remove sources of ignition immediately.
Stop flow of material if safe to do so. Contain spill and keep out of water courses. Ventilate area.
SECTION 7 - HANDLING AND STORAGE
Prevent inhalation of vapor, ingestion, and contact with skin eyes and clothing. Keep container closed when
not in use. Precautions also apply to emptied containers. Change soiled work clothes frequently. Clean hands
thoroughly after handling. Do not smoke, weld, generate sparks, or use flame near container. To prevent
generation of static discharges, use bonding/grounding connection when pouring liquid. Extinguish all ignition
sources including pilot lights, non-explosion proof motors and electrical equipment until vapors dissipate. Store
under dry warehouse conditions away from heat and all ignition sources.
SECTION 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
Personal protection equipment
Respiratory protection : Wear appropriate, properly fitted NIOSH/MSHA approved respirator when
airborne contaminant level(s) are expected to exceed exposure limits
indicated on the MSDS. Select positive pressure supplied air respirator
(TC19C or equivalent) for isocyanates.
Hand protection : Use suitable impervious nitrile or neoprene gloves and protective apparel to
reduce exposure.
Eye protection : Wear appropriate eye protection.Wear chemical safety goggles and/or face
shield to prevent eye contact. Do not wear contact lenses. Do not touch eyes
with contaminated body parts or materials. Have eye washing facilities readily
available.
Skin and body protection : Prevent contact with shoes and clothing.
Protective measures : Use professional judgment in the selection, care, and use.
Engineering measures : Use only in well ventilated areas. Provide maximum ventilation in enclosed
areas.Use local exhaust when the general ventilation is inadequate.
