| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking. NO contact with oxidants and acid(s).
|
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide.
|
| EXPLOSION |
Vapour/air mixtures are explosive. Risk of fire and explosion on contact with oxidants.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Cough. Sore throat. Burning sensation. Nausea. Headache. Vomiting. Laboured breathing. Convulsions.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Half-upright position. Refer immediately for medical attention.
|
| Skin |
MAY BE ABSORBED! Redness. Pain. (Further see Inhalation). |
Protective gloves. Protective clothing.
|
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention .
|
| Eyes |
Redness. Pain.
|
Face shield or eye protection in combination with breathing protection.
|
Rinse with plenty of water (remove contact lenses if easily possible).
|
| Ingestion |
Sore throat. (Further see Inhalation).
|
Do not eat, drink, or smoke during work. Wash hands before eating.
|
Rinse mouth. Rest. Do NOT induce vomiting. Refer immediately for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS FUMING AND HYGROSCOPIC LIQUID , WITH PUNGENT ODOUR. TURNS YELLOW ON EXPOSURE TO AIR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: On combustion, forms toxic fumes including nitrogen oxides. The substance is a strong reducing agent and reacts violently with oxidants. The substance is a strong base, it reacts violently with acid and is corrosive. Reacts with oxygen causing fire and explosion hazard. Attacks plastic. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.01 ppm; as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2008). MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 2; (DFG 2008). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). The substance may cause effects on the central nervous system and liver. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the blood , resulting in anaemia. This substance is possibly carcinogenic to humans. | ||

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2 Flash point: -15°C c.c. Auto-ignition temperature: 249°C Explosive limits, vol% in air: 2.4-20 Octanol/water partition coefficient as log Pow: -1.19 Viscosity, mm²/s at 25 °C: 0.6 | ||
| ENVIRONMENTAL DATA | |||
|
The substance is 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. The symptoms of lung oedema 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. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT take working clothes home. Rinse contaminated clothes with plenty of water because of fire hazard. Dimazine is trade name.
