TPO Coated Metal

Principle Routes of Exposure

Inhalation and skin (primarily if welding, cutting or grinding. Signs and Symptoms of General handling of metal products typically do not present a Exposure:

Health hazards

Sharp metal edges may cause skin cuts Repeated contact with coating may lead to skin irritation and dermatitis. Upon welding, cutting, or grinding on materials the following signs and symptoms of exposure: Dusts and fumes generated during welding, cutting or welding activities can cause irritation to the eyes, respiratory tract and mucous membranes. Accumulation of zinc oxide dust can cause skin eruptions, typically in warm and moist areas of the body. Inhalation of the zinc oxide fume can cause metal fume fever, symptoms including muscular pain, chills, nausea and vomiting. Symptoms typically last for 24-48 hours, and are not life-threatening nor cause any permanent damage.

Medical Conditions Generally Aggravated by Exposure

As a fume or dust, chronic respiratory disorders, including (but by Exposure: not limited to) asthma, chronic bronchitis and emphysema.

Potential chronic health

No chronic effects are expected due to general handling of metal products. Upon heating of this material (e.g., welding, cutting, or grinding), the following chronic effects may occur: The repeated inhalation of large amounts of manganese dust and fume can cause fibrotic changes in the lung, including some resembling those of silicosis. Additionally, repeated exposures to large amounts of manganese can lead to central nervous system (CNS) effects. Carcinogenicity: None SECTION 4: FIRST AID MEASURES First Aid Procedures: Treat skin cuts via washing wound with soap and clean water, and apply antibiotic. If particles from this material contact the eyes, hold eyelids open and flush immediately with a gentle stream of water for at least 15 minutes, preferably at an eyewash fountain. If particles become imbedded, or irritation continues, get medical attention. Following skin contact, clean immediately by washing affected area with soap and water. In case of inhalation of fumes or dusts, remove to fresh uncontaminated air. Administer oxygen if breathing is labored. Give artificial respiration if breathing has stopped. Get medical attention immediately if oxygen or artificial respiration is administered. While an unlikely means of exposure, in case of accidental ingestion, do not induce vomiting. Get medical attention and advise the physician of the nature of the material. SECTION 5: FIRE FIGHTING PROCEDURES Suitable Extinguishing Media: Not applicable. Material will not burn unless involved in an intense fire supported by surrounding materials. In this case, extinguish using suitable media for surrounding materials. Hazardous Combustion Products: Various metal oxides and carbon oxides. Recommended Fire Fighting No special procedures recommended for solid material. Do Procedures: not permit water to come in contact with molten metal. Unusual Fire and Explosion None for solid material. Small chips, dust or other fines may Hazards: be readily ignitable, generating considerable heat. Molten metal will splatter when it comes in contact with water.
