Toxicology. Inhalation of iron oxide fume or dust causes a benign pneumoconiosis (siderosis). 

The 2003 ACGIH threshold limit value-time-weighted average (TLV-TWA) for iron oxide fume is 5mg/m as total particulate as Fe.

Observe normal precautions appropriate to the circumstances and quantity of the material handled. In the UK, the occupational exposure limits for iron oxide fumes (as Fe) are 5 mg/m long-term (8-hour TWA) and lOmg/m short-term. ... 

Particle Shape. Shape Factors. The method of formation plays a major role in shaping the resultant particles. Particles generated by comminution, attrition, or disintegration resemble the parent material. However, if the method of formation is condensation from vapor or precipitation from solution, the smallest unitary particle may be spherical or cubical. Often condensation is followed immediately by solidification and the formation of chainlike aggregates (e.g., iron oxide fumes, carbon black). In liquid suspensions, similar particle aggregation or flocculation is important in determining suspension behavior. 

The exhaust gases from the BOF consist mainly of carbon monoxide, with some carbon dioxide and nitrogen. They also carry iron oxide fume and fines (mostly less than 3 mm) from the lime and other materials charged into the vessel. 

Iron oxide fume (CAS 1309-37-1) Fumes and dusts can produce a benign pneumoconiosis (siderosis) with shadows on chest radiographs. 5 mg/m (as Fe) 2500 mg/m (as Fe) Red-brown fume with a metallic taste. Vapor pressure is negligible at 20°C (68°F). 

In manual metal arc and shielding gas welding fumes nickel is dissolved in the iron oxide fume particles and in small amounts it exists as separate nickel oxide particles. 

While we ttstralfy use the word firme loosely, in occupational hygiene we mean very fine liqtrid or solid particles suspended in air as a result of a liquid or solid becoming a gas or vapom, then reeondensing. The iron/iron oxide fume from welding is an example. This can reach the alveoli.
