Introduction

• This is follow-up to online reading CHP and PPE
  training assignments.
• Fifty min is lt half the usual duration.
• Safety training never, ever ends.

4
Personal Protection

• Personal on your body.

  the required PPE

• Must post written, dated Certification of Hazard
  Assessment in each work area.

For all PPE and possibly for other precautions

Gas Cylinder Safety (high P, approx 2500 psi,
not cryogens)

• Secure tank above center of gravity.
• Cap while in transit and not in use.
• Uncapped cylinder to be supported individually.
• Move only with proper cylinder cart.

Gas delivery from cylinders

• ALWAYS use a regulator.
