Reducing Worker Exposure to Asphalt Fumes from Roofing Kettles. Roofers, particularly kettle operators, may be exposed to asphalt fumes when asphalt is heated in roofing kettles for built-up roof construction. Asphalt fumes have been associated with a number of health risks. NIOSH examined two engineering controls for reducing exposure to ...

Asphalt fumes. Asphalt is a petroleum product used extensively in some construction work. When asphalt is heated for use, it releases fumes that can be harmful to workers.

support a finding that asphalt fumes pose a cancer hazard. Only two of the animal studies done to date tested asphalt fumes. The first of these was a 1980 "skin-painting" study of mice exposed to asphalt fumes generated using a unique labora-tory procedure specially designed to produce the large quantities of fumes needed for this type of ...

Asphalt Fumes. Asphalt is used for paving and surfacing roads, roofing, concrete work, and paints. It is made from petroleum products and is usually heated between 150-200 degrees F. Asphalt is often mixed with solvents (diesel, kerosene, naphtha, toluene, and xylene), binders, hardening and bonding agents (resins), crushed rock, sand, and ...

Asphalt is a blackish-brown solid, semi-solid or liquid, depending on the formulation or mixture of Asphalt used. Asphalt fumes are produced during the manufacture and heating of Asphalt, which is used for road building and roofing, and in rubber and adhesives. REASON FOR CITATION * Asphalt is on the Hazardous Substance List because it is

Millions of tons of asphalt are produced and used every year in the paving and roofing industries. Over a half-million workers are exposed to fumes from asphalt. Health effects from exposure to asphalt fumes can include headache, skin rash, sensitization, fatigue, …

Exposure to asphalt fumes can cause serious injury and permanent damage. Workers that may be exposed to asphalt fumes need to be aware of the potential hazards in their work environment. The following references aid in recognizing asphalt fume hazards in the workplace ...

Asphalt is a petroleum product, so clearly you do not need to eat it, or inhale deep breaths of sizzling asphalt fumes. However asphalt can also be inert when it is cool. There's nothing to breathe in.

Over a half-million workers are exposed to fumes from asphalt, a petroleum product used extensively in road paving, roofing, siding, and concrete work 1.Health effects from exposure to asphalt fumes include headache, skin rash, sensitization, fatigue, reduced appetite, throat and …

Occupational Exposure Levels. There is no OSHA standard or permissible exposure level of asphalt fumes, although a 5 mg/m 3 permissible exposure limit (PEL) was proposed in 1992. OSHA's quantitative risk assessment estimated a significant risk of lung cancer among exposed workers at levels as low as 0.2 mg/m 3.The American Conference of Governmental Industrial Hygienists (ACGIH) currently ...

Asphalt Fume Exposures During the Manufacture of Asphalt Roofing Products. DHHS (NIOSH) Publication No. 2001-127 (August 2001) This document represents the collaborative efforts of industry, labor, and government to protect the health of workers exposed to asphalt fumes during the manufacture of asphalt roofing products.

Asphalt fumes are fumes generated from the heat dried mixture of bitumen, aggregate and sand. Most times, we use both asphalt and bitumen interchangeably; which is wrong. Bitumen is actually a liquid binder which holds the asphalt together, while asphalt is a composition of aggregate, sand and bitumen exposed to heating and drying in a plant ...
