Ingestion Give 2-4 cupfuls of water or milk.
Get medical aid immediately.
Never give anything by mouth to an unconscious person.

Wear appropriate personal protective equipment.
Use bunding or absorption with inert material (e.g. dry sand, earth) to prevent product from entering drains or surface water.
Ventilate area of leak or spill. Remove all sources of ignition.
Evacuate unnecessary and unprotected personnel.
Contain and recover liquid when possible.
Collect liquid in an appropriate container or absorb with an inert material.
Do not flush to sewer.
For small quantities, wipe off with cloth or paper, and wash with water and detergent.
For large quantities, recover by taking up mechanically or with an inert absorbent material such as waste cloth, dry sand, or earth.
Wash residue with water and detergent.
Follow prescribed procedures for responding to larger spills and reporting to appropriate authorities.

Handling Workshops should be well ventilated.
Avoid contact with skin and eyes. Avoid injection and inhalation.
Avoid contact with heat, sparks and flame.
Use proper bonding and grounding procedures to reduce potential for static discharge.
Use spark-proof tools and explosion-proof equipment.
HDI homopolymer reacts slowly with water to form CO2 gas.
This gas can cause sealed container to expand and possibly rupture explosively.
The routine use of neutral or weak acid type of hand cleaner and regular cleaning of working surfaces, gloves, etc. will help minimize the possibility of a skin reaction.
Keep container tightly closed. Store in a cool, dry, well-ventilated area.
Keep away from sources of ignition.
