Commitment to Safety

Safety as a Core Value

Safety is not just a guideline — it is central to every cryogenic system CSM supplies. All products are designed, maintained, and operated with safety as the top priority.

Safety in the Lifecycle of a Cryogenic System

Cryogenic systems supplied by CSM follow a carefully managed lifecycle, designed to ensure safety, performance, and reliability from initial design to decommissioning. Each phase involves CSM’s guidance and support to help customers operate safely and efficiently. 

 

 

Key Hazard & Precautions 

This section provides a quick-reference overview of the main hazards associated with cryogenic systems and the corresponding precautions that must be followed. It is intended to give operators and personnel immediate awareness of critical safety considerations before handling, operating, or maintaining cryogenic equipment.

 

Lifecycle Phase

 Design & Engineering Manufacturing & 
Quality Assurance		 Delivery & 
Installation		 Commissioning & 
Start-Up		 Operation & 
Maintenance		 Upgrades & 
Modifications		 Decommissioning & 
Disposal
CSM Role Develop system designs according to GMP principles, customer  specifications, and cryogen characteristics Fabricate cryogenic systems under controlled manufacturing conditions adhering to GMP standards Ensure safe transport, handling, and installation of systems at the customer site Support controlled commissioning to verify system performance and safety compliance

Provide operational guidance and maintenance protocols in line with GMP standards

 Advise and support any system modifications or capacity upgrades Provide guidance for safe system shutdown and environmentally responsible disposal
Key Controls
  • Material selection based on low temperature performance and chemical compatibility
  • Calculation of pipeline sizes, valve ratings, and relief system capacities
  • Incorporation of safety features such as oxygen sensors, pressure relief devices, and insulation
  • Documented design review and approval process
  • Material verification, traceability, and certification
  • Welding, assembly, and insulation checks according to standard operating procedures (SOPs)
  • Pressure testing and integrity verification of vessels, pipelines, and valves
  • Documentation of all inspections and quality checks
  • Specialized transport procedures to prevent mechanical damage or contamination
  • Verification of pre-installation readiness
  • Controlled lifting, alignment, and connection of equipment
  • Compliance with site-specific safety procedures
  • Documented installation checklist and acceptance record
  • Purging and inerting procedures with documented verification
  • Controlled cooldown of equipment following SOPs
  • Functional verification of valves, sensors, alarms, and relief devices
  • Recording commissioning  parameters and approvals
  • Detailed SOPs for routine operation and monitoring
  • Scheduled inspections of pipelines, valves, and insulation
  • Preventive maintenance procedures  documented and tracked
  • Training programs for operators and maintenance personnel
  • Evaluation of changes for safety and regulatory compliance
  • Risk assessments and updated SOPs for modified systems
  • Controlled implementation following LOTO and documented approval
  • Controlled depressurization and venting
  • Purging residual cryogens  according to SOPs
  • Safe dismantling and removal of equipment
  • Documentation of  decommissioning activities for traceability
Customer Assurance Systems are designed to minimize operational risk and ensure consistent performance High-quality, factory-tested systems ready for safe installation and compliant with regulatory requirements Systems arrive and are installed safely, preserving operational integrity Systems operate safely and in accordance with design specifications from the outset Operational safety, reliability, and traceability are maintained throughout system service life Enhancements are implemented without compromising safety or system integrity Minimizes risk to personnel and environment, ensuring regulatory compliance at end-of life
 


 

Hazard Precaution
Cryogen residue Purge all systems thoroughly before maintenance or disassembly
Energized system Verify mechanical and electrical connections before operation
Cold Burns Use insulated gloves, face shields, protective footwear
Oxygen Depletion Operate in well-ventilated areas; monitor oxygen levels
Pressure Build-Up Depressurize system before maintenance
Emergency Situations Be familiar with emergency venting and shutdown procedures
Regulatory Compliance Be familiar with emergency venting and shutdown procedures
