Safety with Cylinder:
High pressure gas cylinders are made from steel or Aluminium alloys fitted with valves. The contents are identified by adhesive labels, stenciling and a system of color coding. The following Information is marked on each cylinder by permanent stamping:
- Cylinder Marking
- Filling pressure
- Test pressure
- Manufacturer and country of Origin
- Serial Number
- Stamp of official authority
- Date of previous pressure tests and/or inspections with the stamps of the testing/inspection authorities.
- Cold rolled sheets, strips and coils.
These marks must never be removed or defaced. Cylinders can only be filled if they carry the correct information.
Safety with Acetylene:
When calcium carbide and water are mixed, acetylene and lime sludge are produced. Acetylene burns in air, with a smoky flame and when burning it develops a lot of heat at high temperature. Mixtures of acetylene and air are very easy to ignite or explode, for example by a spark, small flame or hot spot.
Safeguards:
- Ventilate areas where acetylene may be present
- Do not smoke
- Do not produce sparks
- Do not produce hot spots
- Use only explosion-proof electrical equipment
- Do not tolerate acetylene leaks.
- Avoid producing air/acetylene mixtures.
- Do not allow air to enter acetylene circuits.
- Purge air from acetylene circuits with nitrogen before admitting acetylene.
- Before beginning maintenance work, purge acetylene circuits with nitrogen.
