UN #: 1994
EINECS #: 236-670-8

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.  Use water spray, powder, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
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 CLASSIFICATION & 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. 

According to UN GHS Criteria

IRON PENTACARBONYL ICSC: 0168
PHYSICAL & CHEMICAL INFORMATION

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. 

Formula: C5FeO5 / Fe(CO)5
Molecular mass: 195.9
Boiling point: 103°C
Melting point: -20°C
Relative density (water = 1): 1.5
Solubility in water: none
Vapour pressure, kPa at 25°C: 4.7
Relative vapour density (air = 1): 6.8
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.2
Flash point: -15°C c.c.
Auto-ignition temperature: 50°C
Explosive limits, vol% in air: 3.7-12.5 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

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. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

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


Occupational exposure limits
TLV: 0.1 ppm as TWA; 0.2 ppm as STEL.
MAK: 0.81 mg/m3, 0.1 ppm; peak limitation category: I(2); skin absorption (H); pregnancy risk group: D 

ENVIRONMENT
 

NOTES
Environmental effects from the substance have not been investigated.
The symptoms of shortness of breath, cough, cyanosis, fever do not become manifest until after 12-36 hours.
No odour warning if toxic concentrations are present.
Do NOT take working clothes home.
Rinse contaminated clothes (fire hazard) with plenty of water.
