SECTION 1 CHEMICAL PRODUCT IDENTIFICATION

TRADE NAME Oleum

CHEMICAL NAME Sulfuric acid & Sulfur trioxide

EMERGENCY CONTACT NO. (02632) 233261 to 233265

SECTION 2 COMPOSITION/INFORMATION ON INGREDIENTS
INGREDIENTS CAS #


Sulphuric acid 98 % 7664-93-9
Sulfur Trioxide 7446-11-9


SECTION 3 HAZARDS IDENTIFICATION
Can cause severe burns or irritation. Liquid contact can cause severe burns to eyes, irritation or blindness. May cause permanent injury to eyes.
