TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, 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).
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, then remove contaminated clothes and rinse again. Refer for medical attention.
Eyes
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 take to a doctor.
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! Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: self-contained breathing apparatus.
Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

IRON PENTACARBONYL ICSC: 0168
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 spontaneously ignite on contact with air. The substance decomposes on heating, on burning or under influence of light producing toxic gases including iron oxides and carbon monoxide (see ICSC0023). The substance is a strong reducing agent and 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/m; Peak limitation category: II(2); Pregnancy risk group: IIc; (DFG 2004).
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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the lungs. Exposure far above the OEL may result in 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, resulting in impaired functions.
PHYSICAL PROPERTIES
Boiling point: 103C
Melting point: -20C
Relative density (water = 1): 1.5
Solubility in water: none
Vapour pressure, kPa at 25C: 4.7
Relative vapour density (air = 1): 6.8
Relative density of the vapour/air-mixture at 20C (air = 1): 1.2
Flash point: -15C c.c.
Auto-ignition temperature: 50C
Explosive limits, vol% in air: 3.7-12.5
ENVIRONMENTAL DATA

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.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response.
