TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, carbon dioxide, foam, powder.
EXPLOSION Above 96°C explosive vapour/air mixtures may be formed. Above 96°C use a closed system, ventilation.  
 
EXPOSURE   STRICT HYGIENE!  
Inhalation Dizziness. Drowsiness. Headache. Nausea. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.
Skin MAY BE ABSORBED! (See Ingestion) Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes   Safety spectacles or eye protection in combination with breathing protection. Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion Blue lips or fingernails. Blue skin. Dizziness. Drowsiness. Headache. Nausea. Unconsciousness. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL PACKAGING & LABELLING

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-61S1711-L
NFPA Code: H3; F1; R0

IMPORTANT DATA
Physical State; Appearance
CLEAR, PALE YELLOW LIQUID, WITH CHARACTERISTIC ODOUR. TURNS REDDISH TO BROWN ON EXPOSURE TO AIR.

Chemical dangers
The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides. Reacts violently with strong oxidants. Reacts with hypochlorites forming explosive chloroamines. Reacts with acids, acid anhydrides, acid chlorides and halogens. Attacks plastic and rubber.

Occupational exposure limits
TLV not established. See Notes.
MAK: Skin absorption (H); Carcinogen category: 3A; (DFG 2006).

Routes of exposure
The substance can be absorbed into the body in hazardous amounts by inhalation, through the skin and by ingestion.

Inhalation risk
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

Effects of short-term exposure
Exposure at high levels could cause lowering of consciousness. Exposure at high levels may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
The substance may have effects on the blood, resulting in anaemia.

The substance is very toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
