TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Headache. Dizziness. Vomiting. Laboured breathing. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED!  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes   Wear face shield 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.  Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.  Airtight.
Unbreakable packaging.
Put breakable packaging into closed unbreakable container.
Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW OR DARK RED VISCOUS LIQUID. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
May explode on heating. The substance may ignite spontaneously on contact with air. Decomposes on heating and on burning. Decomposes under the influence of light. This produces toxic gases including iron oxides and carbon monoxide (see ICSC0023). The substance is a strong reducing agent. It reacts violently with oxidants. 

Occupational exposure limits
TLV: 0.1 ppm as TWA; 0.2 ppm as STEL; (ACGIH 2004).
MAK: 0.1 ppm, 0.81 mg/m³; Peak limitation category: II(2); Pregnancy risk group: D; (DFG 2006). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, 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 may cause effects on the lungs. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated. See Notes. 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in impaired functions.
