PipeWrap CT 337 (Synonyms : Coal Tar Tape)

SECTION 2: Hazards identification

2] Hazards Identification]] Emergency Overview: A fiberglass tissue coated with a black solid with little to no odour. Has an aromatic, tarry odour at elevated temperatures. Carcinogen. Toxic. Irritant. Sensitizer (skin). Signs and PipeWrap® CT 337 contains coal tar pitch, coal tar oils, coal powder Symptoms of and talc. Talc is non-toxic upon oral and dermal exposure, but Potential inhalation exposure of excessive quantities or low level inhalation Overexposure: exposures over long periods of time may lead to respiratory distress syndrome and talc pneumoconiosis, a form of pulmonary fibrosis. This type of exposure is unlikely from coal tar enamel as the talc is thoroughly incorporated in the coal tar pitch. Coal tar pitch vapours and dust are irritating to the skin, eyes and respiratory tract. Direct skin contact with coal tar pitch dust and /or high vapor concentrations may cause burning and itching, changes in pigmentation and skin eruptions. When accentuated by sunlight, skin exposure may result in a photo toxic skin reaction. Direct eye contact with enamel vapour, dust may cause inflammation, discomfort, conjunctivitis, and possible abrasion of the cornea. Care should be taken ensure that exposure limits for vapour, dust are not exceeded if enamel dust are present (OSHA PEL for particulates=15 mg/m³ for total dust; 5 mg/m³ for respirable fraction) Primary Skin contact, skin absorption, eye contact, inhalation, ingestion

Medical Conditions Generally Aggravated by Exposure

Persons with pre-existing skin disorders or central nervous functional illness may be at increased risk from overexposure. Exposure to vapours may aggravate pre-existing lung conditions. This is not likely Exposure: to be a problem when appropriate procedures are used to minimize exposure.
