3. HAZARD IDENTIFICATION
Inhalation Repeated or prolonged exposure may irritate the respiratory tract.
Avoid generating dusts
Skin contact May cause irritation with prolonged contact. Avoid contact with skin
Eye contact May cause mild irritation
Ingestion Do not take internally. Ingestion of product may cause the formation
of a jelly-like mass which may result in a intestinal obstruction
Human health hazards - Chronic No adverse effects expected
Environmental hazards No adverse effects expected. Do not contaminate water courses
Physical and chemical hazards Wet floor on which this powder is split may become very slippery.
This powder, when dispersed in air, represents an explosion hazard
4. FIRST AID MEASURES
Inhalation Remove to fresh air. Obtain medical attention
Skin contact Remove contaminating clothing. Wash off affected area with plenty
of water
Eye contact Gently irrigate with water for at least 15’. Obtain medical attention
Ingestion Rinse mouth immediately and repeatedly with water. Obtain medical
attention

5. FIRE FIGHTING MEASURES
Extinguishing media In case of fire use water spray, foam, powder, carbon dioxide
Unsuitable extinguishing media None
Fire and explosion hazard Powder when dispersed in air represents an explosive hazard
Protective equipment In case of fire wear a full face positive pressure self contained
breathing apparatus and protective suit
6. ACCIDENTAL RELEASE MEASURES
Personal precautions Do not breathe powders. Avoid the contact with eyes and skin
Environmental precautions No adverse effects expected
Methods for cleaning up Remove as much as possible with broom, scoop or vacuum, as the
addition of water causes slippery floor conditions. System should be
earthed to avoid risk of ignition by static electricity. The product
makes the ground slippery when wet.
7. HANDLING AND STORAGE
Handling Avoid dust formation, maintain good ventilation and a clean area
Storage conditions Keep product dry. Store under cover
