Compressed Gas Cylinder Safety Signs in India: SMPV and PESO Requirements
By Super Admin
·
Pressure Vessels That Workers Handle Every Day
Compressed gas cylinders are among the most common industrial hazards in India — found in virtually every factory, hospital, laboratory, and workshop. Oxygen, acetylene, nitrogen, argon, CO2, hydrogen, LPG, and dozens of specialty gases are stored in high-pressure cylinders that can become projectiles if mishandled. The Static and Mobile Pressure Vessels (SMPV) Rules and PESO licensing requirements mandate specific safety signage.
Cylinder Storage Area Signs
- "Compressed Gas Cylinder Storage — Authorised Access Only"
- "No Smoking / No Naked Flame" — within 5 metres of gas storage
- "Store Cylinders Upright — Secure with Chain or Bracket"
- "Separate Full and Empty Cylinders" — with clearly identified areas
- "Separate Incompatible Gases" — oxygen away from flammable gases (5 metres minimum or fire-rated wall)
- "Keep Away from Heat Sources"
- "Ventilate Cylinder Storage Area"
