DANGER

Health hazards

CONTAINS VINYL CHLORIDE, A KNOWN HUMAN CANCER AGENT. CONTACT WITH LIQUID MAY CAUSE FROSTBITE TO EXPOSED TISSUE. MAY PRODUCE SYMPTOMS OF CENTRAL NERVOUS SYSTEM DEPRESSION INCLUDING HEADACHE, DIZZINESS, NAUSEA, LOSS OF BALANCE AND DROWSINESS. MAY CAUSE RESPIRATORY IRRITATION. CAUSES DAMAGE TO THE NERVOUS SYSTEM, MUSKOSKELETAL SYSTEM, LYMPHATIC SYSTEM AND RESPIRATORY SYSTEM THROUGH PROLONGED OR REPEATED EXPOSURE. SUSPECTED OF CAUSING GENETIC DEFECTS. MAY CAUSE CANCER. THIS MATERIAL IS A POTENTIAL ENDOCRINE DISRUPTOR.

2.3 Other hazards

(HNOC)-Health • Repeat occupational exposure to Vinyl Chloride have been associated with Raynaud syndrome and associated scleroderma-like skin changes on the hands • Direct contact with liquid or rapidly expanding gas may cause frostbite to contacted tissue (eyes, skin, etc.) • Vinyl Chloride is listed on The Endocrine Disruptors Exchange's (TEDX) List of Potential Endocrine Disruptors database of chemicals with the potential to affect the endocrine system. Every chemical on the TEDX List has one or more verified citations published, accessible, primary scientific research demonstrating effects on the endocrine system • May displace oxygen and cause rapid suffocation See Section 11: TOXICOLOGICAL INFORMATION _________________________________________________________________________________________________
