🔍 Key Concepts

• Physical hazards of cathode-ray tubes (CRTs) such as glass envelope and vacuum • Implosion risk and flying glass fragments • Personal protective equipment (PPE) appropriate for fragile, evacuated glass devices

💭 Think About

• If a CRT is under high vacuum, what could happen if it cracks or breaks while you are handling it? • Why would eye and hand protection be especially important when dealing with a large glass tube under vacuum? • Besides wearing protection, what handling practices reduce the chance of damage or breakage to the tube?

✅ Before You Answer

• Confirm whether a CRT is fragile glass under vacuum and what that implies for impact or dropping • Consider if implosion risk alone covers all necessary safety precautions or if more are needed • Check which option best combines handling care and personal protection for CRT work
