2 Never use as a sole method to identify gas contents a Tags b Colour c Labels?

Answer 1

Using tags, color codes, or labels as the sole method to identify gas contents is unreliable because these methods can be easily misinterpreted or damaged, leading to potential hazards. Tags may not accurately reflect the current contents if they are outdated or incorrectly applied. Similarly, colors can vary by manufacturer and may not be universally understood. Therefore, it's essential to use additional methods, such as gas detection instruments, for accurate identification and safety.
