MSDS of Oxidized bitumen:

vapour of oxidized bitumen or mist can cause headache, nausea, irritation of nose and lungs.

Eye Contact: oxidized bitumen can cause slight irritation.
Prolonged or continual skin contact: oxidized bitumen can cause slight skin irritation.

Contact with hot material: oxidized bitumen can cause thermal burns which may finish in permanent skin injury. Hot product may cause severe eye burns and/or vision defect.

Safety Hazards oxidized bitumen is not classified as inflammable. Contact of hot material with water will finish in vio-Lententide growth and splashing or boil-over may occur.

Environmental Hazards: oxidized bitumen is not classified as dangerous for the atmosphere.

Oxidized bitumen grades unit of measurement blown or alter bitumen ‘s that unit of measurement created by passing air through soft bitumen below controlled temperature conditions. This methodology provides the bitumen further rubbery properties than penetration or exhausting grade bitumens, and a variety of uses in industrial applications.

Oxidized bitumen grades unit of measurement acceptable for waterproofing saw cuts and joints where there is expected to be the minimum amount of obtaining the joint. Their wide temperature vary prevents hurt in hot temperature applications. Alter oxidized bitumen will even be utilized in industrial applications like roofing, flooring, mastics, pipe coatings, electrical applications to decision several.

Oxidized bitumen created by further vigorous air process and it’s acceptable for roofing, flooring, mastics, pipe coatings, electrical applications to decision several.

In every crude supply comparison cluster, every progressive modification within the extent of chemical reaction made marked changes in softening purpose, penetration and body. additionally, measures of volatility and fuming potential shrivelled markedly because the straight run roofer’s fluxes were subjected to progressively bigger chemical reaction process.

The issue is that it’s inaccurate to assume, as some existing reviews do, that everyone oxidised bitumen used in roofing area unit modify , or have physical properties and fuming characteristics a bit like BUR oxidized bitumen. The recognition that oxidised bitumen used in roofing exhibit a decent vary of physical properties and reply to heating in markedly alternative routes has two important implications first, the only necessary due to classify oxidized bitumen roofing merchandise keep with their fume exposure potential is to cluster them keep with application technique i.e., hot, soft and  cold. Second, the’ temperature is certainly a significant take into account fume emission rate and composition, it’s inappropriate to possess confidence temperature alone as degree indicator of fume exposure potential in hot application operations. various problems, beside the physical properties of the oxidised bitumen and operational factors like work practices and environmental conditions, ought to be thought-about in conjunction with temperature in evaluating potential worker fume exposures.
