Farmers have been advised by Teagasc to review their tyre pumping practices.
Serious accidents, including fatalities, have been caused by unsafe practices during wheel/tyre changing and when inflating tyres.
The UK Health and Safety Executive has advice on extra safety measures needed for inflating larger, well-based (single-piece) commercial vehicle tyres above 15 psi.
This includes some light commercial vehicle tyres which are inflated to around 70 psi, and may cause serious injury in the event of failure.
The extra measures include using a restraining device such as a strong, firmly-secured tyre inflation cage.
Consider lining this with mesh, to retain debris.
For fixed installations, it is helpful to mark the safety exclusion zone on the workshop floor, as a reminder to staff. Other recommended extra measures include a secured horizontal stool and associated clamping mechanism, or a portable restraint such as a lightweight fabric cover that encloses the tyre and wheel rim.
This may be particularly useful for off-site repairs.
In the event of an explosion, the cover reduces flying debris.
The cover may need to be replaced after an explosion.

It Advocates:
When using jacks to lift or support vehicles or machines, use the correct jack for the job, capable of supporting the load imposed on it. Use the correct jacking point, as identified on the machine or in the operator’s manual.
Position axle stands to give additional support; chock the other wheels to prevent movement; and carry out the work on firm, level ground.
Use a clip-on chuck to connect the air-line. with a quick-release coupling at the operator’s end.
Use air-line hoses which are long enough to allow the operator to stay outside the likely explosion trajectory during inflation
Use enough bead lubricant when seating the tyre, and remove the air-line after use, to prevent air seepage and possible over-inflation.
Don’t use a valve connector that requires the operator to hold it in place.
Don’t use ‘unrestricted’ air-lines, or allow the control valve to be jammed open.
Don’t exceed the manufacturer’s recommended tyre pressure.
Tyre/wheel repair and replacement should only be tackled by competent staff.
Take extra care with split-rim wheels, as these present additional hazards.
Although they are becoming less common, you may find them on older vehicles such as forklift trucks, and loading shovels.
If in doubt, seek help from a specialist.
Changing large tractor wheels can be made easier with an appropriate mechanical handling trolley.
