Purpose of Hazard Communication
  • To ensure that employers and employees know about
    work hazards and how to protect themselves so
    that the incidence of illnesses and injuries due
    to hazardous chemicals is reduced.

    If evidence exists, contact EHS immediately!

Section Three
36
What Should I Look For on Cryogenic Cylinders?
  • Report any excessive venting or leakage to the
    vendor and EHS.

    rupture disc are present on the cylinder prior to
    filling or usage

    each chemical
  • Label all containers with their contents

82
Conclusion
  • Know the hazards and risks in your lab and the
    consequences of an incident
  • Keep in mind the safety of compressed gas and
    cryogenic cylinders
  • Practice good chemical storage and handling
    techniques
  • Wear the Proper Protective Equipment at all times

83
