Hydrogen N4.5 – Safety, Regulations, and Identification

Safety Guidelines

Before using Hydrogen N4.5 in any new process or experiment, you must carry out a thorough material compatibility and safety study.

• Ensure adequate air ventilation.
• Observe all national and local regulations.
• Confirm that equipment is adequately earthed.

This document has been prepared with care. However, no liability for injury or damage resulting from its use can be accepted.

Note on SDS formatting:
When the product name appears in the SDS header, the decimal sign follows international standards.

• 2,000 = two (to three decimal places), not two thousand.
• 1.000 = one thousand, not one (to three decimal places).

National Regulations for Hydrogen N4.5

Hydrogen N4.5 is subject to the following regulations:

• Dangerous Substances and Explosive Atmospheres Regulations (DSEAR 2002 No. 2776)
• Management of Health and Safety at Work Regulations (1999 No. 3242)

This Safety Data Sheet complies with Regulation (EU) 2015/830.

Gas Grades – Purity Classification

Pure gases are classified by grade:

• The first digit indicates the “number of nines” purity.
• The second digit represents the number following the last nine.

👉 Example: N3.0 = 99.9% purity.
👉 Example: N4.6 helium = 99.996% purity.

Transport Precautions

• Avoid transport in vehicles where the load space is not separated from the driver’s compartment.
• Ensure the driver is aware of hazards and knows emergency procedures.
• Secure product containers firmly before transport.
• Close container valves and check for leaks.
• Keep valve guards or caps in place.
• Maintain adequate ventilation during transport.
