A mechanic was inflating a tire on a pressure washer machine, using a remote air chuck.
When he went to remove the chuck, the two-piece wheel separated with great force, causing a fracture to the mechanic's wrist.
See the attached pdf for photos of the damaged wheel assembly.
Learnings and Suggestions:
• When inflating any tire, inspect the tire and wheel assembly for possible defects (such as cracking, deformation, and excessive rust) prior to inflation. Determine why the tire is leaking air prior to fully inflating it. Removal of the tire from the wheel is normally required for a complete inspection.
• Never exceed the manufacturer’s maximum air pressure recommendation.
• Be aware that small tires such as those found on pressure washers and wheel barrows will inflate very quickly when using compressed air. Always add air in small quantities at a time, checking the pressure often, until the desired pressure is attained.
• Tire sealant products have been known to help lower-quality small tires hold their air. Use should be limited to hand pushed applications such as wheel barrows, hand carts and power washers.
• Large tire inflation has unique procedures. Do not attempt removal, inflation or repair unless properly trained.
