	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with combustible substances.	NO contact with combustible substances or reducing agents.	In case of fire in the surroundings, use appropriate extinguishing media.

PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Shortness of breath.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves. Protective clothing.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.
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	Abdominal pain. Nausea. Vomiting.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.	According to UN GHS Criteria Harmful if swallowed Causes skin and eye irritation May cause respiratory irritation May cause allergy or asthma symptoms or breathing difficulties if inhaled May cause an allergic skin reaction May cause cancer if inhaled Suspected of causing genetic defects May damage fertility or the unborn child May cause damage to thyroid, bone marrow and heart through prolonged or repeated exposure if swallowed Toxic to aquatic life with long lasting effects Transportation UN Classification
STORAGE
Provision to contain effluent from fire extinguishing. Separated from combustible substances. Well closed. Store in an area without drain or sewer access.
PACKAGING
Do not transport with food and feedstuffs and combustible materials.

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 A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the bone marrow, heart and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

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
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the bone marrow, heart and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Co, inhalable fraction): 0.02 mg/m³, as TWA; (DSEN); (RSEN); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued. MAK: (as Co, inhalable fraction): skin absorption (H); sensitization of respiratory tract and skin (SAH); carcinogen category: 2; germ cell mutagen group: 3A

ENVIRONMENT
Environmental effects from the substance have not been investigated adequately. It is strongly advised not to let the chemical enter into the environment.

NOTES
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Depending on the degree of exposure, periodic medical examination is suggested. Do NOT take working clothes home.
