Dust entry

Trimellitic anhydride dust

Airborne trimellitic anhydride dust or fume generated during production and use in plasticisers, wire enamels, coatings, and flooring materials.

Airborne form

fume

The form describes what is suspended in air at the point of exposure. A material can produce more than one form, such as dust during handling and fume during heating.

Evidence

The UK HSE review identifies respiratory syndromes among workers exposed to trimellitic anhydride dust or fume, including immediate or late asthmatic symptoms and rhinitis, and classifies it as a respiratory sensitiser under its reviewed criteria.

A number of toxic syndromes which involve respiratory reactions have been identified in workers exposed to trimellitic anhydride dust or fume. The respiratory reactions include asthmatic symptoms, of either immediate or late onset, and rhinitis. In some individuals known to suffer from trimellitic anhydride-associated respiratory illness, exposure to very low airborne concentrations of the anhydride can provoke symptoms.

NIOSH reports that trimellitic anhydride exposure can cause eye, skin, nose, and respiratory irritation, pulmonary edema, respiratory sensitization, rhinitis, asthma, cough, wheezing, and breathing difficulty.

Exposure Routes; Symptoms · 1

Exposure Routes inhalation, ingestion, skin and/or eye contact. Symptoms irritation eyes, skin, nose, respiratory system; pulmonary edema, resp sensitization; rhinitis, asthma, cough, wheezing, dyspnea.

Controls

enclose trimellitic anhydride production and transfer
use local exhaust ventilation
avoid airborne dust and fume generation
protect skin and eyes
use appropriate respiratory protection where exposure assessment indicates it is needed
