	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks and NO smoking. NO contact with flammables. Do NOT expose to friction or shock.	In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Wear safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 5.1; UN Pack Group: II
STORAGE
Separated from combustible substances and reducing agents. See Chemical Dangers. Well closed.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE HYGROSCOPIC CRYSTALS OR POWDER. Physical dangers Chemical dangers Decomposes on heating. This produces toxic fumes of chlorine and chloroxides. The substance is a strong oxidant. It reacts with combustible and reducing materials. This generates fire and explosion hazard.	Formula: NaClO₄ Molecular mass: 122.4 Decomposes at 482°C Density: 2.0 g/cm³ Solubility in water: very good

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure The substance may have effects on the blood. This may result in the formation of methaemoglobin. See Notes.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

NOTES
Will turn shock-sensitive if contaminated with organic substances. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Rinse contaminated clothing with plenty of water because of fire hazard. The recommendations on this Card also apply to Sodium perchlorate monohydrate. Depending on the degree of exposure, periodic medical examination is suggested.
