TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		Powder, water spray, foam, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT GENERATION OF MISTS!
Inhalation	Cough. Sore throat.	Ventilation.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves.	First rinse with plenty of water, then remove contaminated clothes and rinse again.
Eyes	Redness. Pain.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Burning sensation. Cough. Diarrhoea. Sore throat. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
In case of a large spillage use personal protection: self-contained breathing apparatus. Ventilation. Wash away spilled liquid with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.	EU classification Xi Symbol R: 31-36/38 S: (1/2-)28-4 Note: B 5-5 0-6 1

EMERGENCY RESPONSE	SAFE STORAGE
	Separated from acids. See Chemical Dangers. Cool. Keep in the dark. Well closed.

IMPORTANT DATA

Physical State; Appearance
CLEAR, SLIGHTLY YELLOW SOLUTION, WITH CHARACTERISTIC ODOUR.

Chemical dangers
The substance decomposes on heating, on contact with acids and under influence of light producing toxic and corrosive gases including chlorine (See ICSC 0126). The substance is a strong oxidant and reacts with combustible and reducing materials. The solution in water is a weak base.

Occupational exposure limits
TLV not established.

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Inhalation risk
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Relative density (water = 1): 1.1 (5.5% aqueous solution)	The substance is toxic to aquatic organisms.

NOTES

Household bleaches usually contain about 5% sodium hypochlorite (about pH11, irritant), and more concentrated bleaches contain 10-15% sodium hypochlorite (about pH13, corrosive).
Rinse contaminated clothes (fire hazard) with plenty of water.
Clorox and Javel water are trade names.
Also consult ICSC #1119 (Sodium hypochlorite, active chlorine >10%).
