TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	Water in large amounts, water spray.
EXPLOSION	Risk of fire and explosion on contact with combustible substances, reducing agents and at warming.	Prevent warming above 25°C.	In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness. Pain.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety goggles or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area in case of large spills! Consult an expert! Remove all ignition sources. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: P2 filter respirator for harmful particles.	O Symbol R: 7 S: (2-)3/7-14-36-37/39 UN Hazard Class: 5.2

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-52GP1-S NFPA Code: H0; F2; R3; OX	Fireproof. Separated from combustible and reducing substances. Cool.

IMPORTANT DATA
Physical State; Appearance WHITE POWDER OR SOLID IN VARIOUS FORMS. Chemical dangers Heating may cause violent combustion or explosion. The substance is a strong oxidant and reacts with combustible and reducing materials, causing fire and explosion hazard. Occupational exposure limits TLV not established.	Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol. Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly. Effects of short-term exposure The aerosol is irritating to the eyes, the skin and the respiratory tract.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 49-57°C Density: 0.9 g/cm³ Solubility in water: none Auto-ignition temperature: 112°C
