Hello, all,
I am looking for some guidance on the prohibition for refilling gas cylinders.
I discovered that at my institution a standard T-sized cylinder is being refilled ~2x/week with compressed air for use with a pneumatic nail gun and for dusting off machines in a wood shop. It has been in use in this fashion for ~10 years.
I am interested in any info you might have to explain why not to do this and in alternatives you might recommend.
Thanks so much in advance for any help you can give me with this,
