We have recently had an incident where someone was cleaning down with an air line when the fitting (schrader type) came out from the hose (held in by a crimped ring). This had not happened before but just wondered what checks anyone has in place to try and prevent this happening again.
Thnks for any ideas

Hi Paul,
I have not had any experience with air lines however could a pre-use check negate this issue? Perhaps if someone had checked prior to use that the fittings were secure this event would not have happened? Have you looked at manufacturers recommendations on this? Georgia

Not sure what they were cleaning down, but you may want to reconsider this practice. We were told not to do this when I was an apprentice ( long time ago). http://www.hse.gov.uk/engineering/faqs.htm

But the HSE faq provides guidance for safe use of airlines
Quote:Blow down components in an extracted enclosure. This could be the machine if it is enclosed and fitted with an effective extraction system.
Reduce the exit pressure of the compressed air to as low a level as possible (As a guide some countries have set a maximum level of 30 psi at the point of exit from the nozzle). Gauges are commercially available for testing this exit pressure.
Consider using air nozzles which have been designed with noise reduction in mind.
Increase the length of the air gun.
Provide a shield on the air gun to reduce splash back.
Provide appropriate training, personal protective equipment, supervision and health surveillance.

Yes sometimes HSE guidance can be a bit contradictory, in HSE 129 pg 41 in the section what operators should know, it states
not to clean machines using compressed air to blow material away – industrial vacuum cleaners or brushes should be used
However as with everything if you can risk assess and put in control measures to prevent getting air into bloodstream, noise issues, dust getting into eyes etc, then all good. But the general vibe is that they do not consider this good practice.

There are small, hand-held devices that vaguely resemble compressed air blow guns but use the venturi effect to create suction. Some can have attachments (brush for removing dust from coveralls, tubes to reach into awkward places etc.) They can be used to suck up small amounts of dust, metalworking fluid etc. If you have difficulty locating these drop me a PM with your e-mail and I will send you more.

Many machine tool builders prohibit the cleaning of their machines with airlines as these can drive dirt and contamination into places on the machine where it can cause damage.
