COMPRESSED BREATHING AIR SAMPLING INSTRUCTIONS

• The compressor and purification system should be running to specification.

• Samples collected for analysis must be representative of the quality of breathing air system. Therefore take the sample at a point that is representative of your normal air demands.

• Make sure your sample cylinder is clean & dry and the hydrostatic test date is valid.

Water content in normal air is 4000 times as much as allowed in a good compressed breathing air sample.

• Once clean, mark one cylinder for air analysis only, use this cylinder for all air testing.

• Always leave a positive pressure in your cylinder between tests.

• When sending a sample for testing, fill your cylinder to full pressure.

• Label your tank with your company name.

• Complete sample submission forms with all the information.

• Know your compressor make and serial number.

• Compressed air should have little or no odour. After filling your tank check for odour. Any pronounced odour will fail the analysis.
