Workers Killed While Servicing Tires

Workers Killed While Servicing Tires


I’m Olaf Knezevic, Engineer with WorkSafeBC. Tires can explode with devastating force,
causing injury or death. I’m going to describe three serious tire accidents. In the first accident, a worker was killed
while removing a tire from a log stacker. This stacker’s tires are mounted on rims made
up of several pieces, including an inner and outer rim. 16 bolts hold together the inner and outer
rim. 48 larger bolts attach the entire rim to the stacker’s hub. To get the wheel off the stacker, the worker
removed most of the large bolts while the tire was still inflated to about 90 psi. The remaining bolts had weakened over time
and could not handle the pressure. They sheared off or stripped. The outer rim and tire blasted towards the
worker, who was facing the tire. The worker was crushed between the tire and
his truck. The tremendous force of the impact can be
seen in the damage where the tire and worker hit the truck. In a second accident, a worker had just repaired
a crack in the rim by welding the rim with the tire still mounted but deflated. After completing the weld, the worker reinflated
the tire. The heat from the welding caused some tire
decomposition, which produced flammable gases. When the worker inflated the tire, the additional
air led to a fire inside the tire, causing it to explode. The huge force of the explosion separated
the tread into 4 flaps, folding them over. One flap struck the worker, causing fatal
injuries. In a third accident, a worker was inflating
a new tractor tire that he had just mounted on a rim. The tire and rim were laid flat on the ground
and the worker was positioned over the tire. The bead of the tire would not seat. To force the bead to seat, the worker kept
adding air. It was too much. The bead burst over the rim flange, catapulting
the worker and tire into the air. The worker fell back down, hit the concrete
driveway, and sustained serious injuries. The tire continued upwards and struck the
underside of the shop canopy. Death or injury could have been prevented
in all three accidents by the following safe work practices. With a multi-piece rim, always fully deflate
the tire before loosening the wheel nuts or bolts. When inflating multi-piece rim and tire assemblies,
always use a suitable restraining device, such as a safety cage, a safety T-bar, or
safety chains. This is also a safe work practice for single-piece
rim and tire assemblies. Keep out of the trajectory when handling or
inflating tires. Inflate tires to the recommended pressure
using a clamp-on air chuck and an in-line valve and gauge. The hose should be long enough to allow the
worker to keep out of the trajectory. Safe tire servicing requires proper equipment,
training, and procedures. Refer to the tire manufacturer’s instructions
for more safe work procedures and remember to always work safely.

  1. This was one of our earliest slide shows. As a result, audio only plays from one speaker or headphone. Thanks for your understanding.

  2. Text a lot of those creep ass wheels on forklifts when inflating those I back a truck up against the wall up against so a truck at the tire in the wall I had a lawn mower tire blow up one time and knock me flat on my rear

  3. at the risk of sounding stupid can a normal car tire explode while adding air, please no smart ass comments

  4. When I worked the service station 50 years ago my boss always insisted I wrap a chain around 2 and 3 piece trims 2 sides to control it if the ring blew off

  5. I worked for Brad Ragan tire company back in the mid seventies. One day a tire blew up on a guy using a skiver, it ripped the front of his shirt open with all the buttons missing and also blinded the man for a few days. I also had a tire blow up on myself while running a buffer which cut the old rubber off so the tire could be recapped. These were what we called Puerto Rico singles, actually just tractor trailer tires. They had been recapped so many times before they would have never been legally allowed on roads in America. Happy motoring Puerto Rico! 👍

  6. It's a pity that outside contractors doing tyres have difficulty inflating to correct pressures, fitting valve extensions and dust caps, cleaning wheel mating surfaces, lubricating collars, sequence tightening and re-torque procedure.
    Ones I see in my local area on call have no proper work ethic that I have seen in my observations of 47 years in a related job.

  7. I saw this video and decided to view it. Reason being. I lived in a little town in SW Georgia back in the latter '90's. In a town next to mine, there was a shop there that repaired tires and rims (etc). Two brothers worked in this shop.

    One day one of the brothers had just finished changing out rims on a pickup truck. After doing so, he inflated the tires to the proper air pressure and was about to lower the truck off the rack. But noticed some spot on one of the rims that required a weld. He grabbed his torch and made the weld.

    You may have guessed it already. He failed to deflate the tire before he made the weld – or better yet, dismount the tire and take it back off the rim/wheel to do the job.

    It did not take long before the heat of the weld transferred to the air in the tire, greatly expanding the air, and then the inevitable happened.

    The explosion rocked the whole commercial area around there. The pickup truck was shot back off the rack in the opposite direction of the blast and was hanging off of it. The exploded tire tore the rim/wheel in two; the outer half flying across the bay striking the wall. But not before taking the face and front part of the skull off one of the brothers – the one working on the tire of this truck. His brother was also injured severly. He was asking how his brother was. No one wanted to tell him what happened to him. It was not a good sight.

    I gained an even greater appreciation and respect for the tremendous power of the physics that are involved in the heating and expansion of air (and H2O).

    Ignorance is NOT bliss. And what you DON'T know CAN KILL YOU!

    "My people are destroyed [perish] for lack of knowledge…" It goes on to say that "…because though hast rejected knowledge, I will also reject thee…"

    To make an application, as an electrician; I had BETTER BE VERY KNOWLEDGEABLE about electrical theory and POSSESS PRACTICAL EXPERIENCE in the field – or I can get myself or others injured or killed, burn property or set up future scenarios that may endanger others. Training.

    I have come in contact with those who are too proud and stubbornly STUPID to consider their ignorance is not an 'asset'. There are different kinds of fools. Those who REFUSE TO TAKE sound advise and warnings, they go their way – and suffer the consequences of their pride, stubbornness and stupidity.

    Then there are other fools, who WHEN they witness the previous kind of fool (I call them 'full-time-fools') suffer the fate of their folly; THEY, take a lesson from it.

    This video reminded me (refreshed my mind) to stay clear of shops where these 'accidents' might occur, due to others failure to appreciate how their ignorance might lead to their death or mine.

  8. Down here in Brasil I show this kind vídeos to several tyre repair guys because they don't wan use tha cage.

  9. "Split rims" should have long, long ago gone way of the DoDo. No excuse and you don't need them anymore. But you do need a safety cage. this is 2019, not 1919.

  10. Anything under pressure is dangerous. I was taught to change truck tyres with bead breakers and levers. I was shown how to clean the rim and split ring and make sure everything fitted well when put back. I was taught to always use a cage to inflate and inspect as it was seating and being inflated. I was shown a split rim embedded at 90 degrees into a hardwood tree and how if it hit a person it would cut in half. It comes down to being trained and responsible. when someone is injured by negligence or incompetence think where you will be legally placed when sitting at an inquest.

  11. A split rim exploded on my dad when he was young. It ripped his skin in half from his arm pit to his ankle. He said he was just working, blacked out and woke up in the hospital days later. Luckily he survived. Be safe people. By the way, don't be an idiot and use flammable liquids to set beads only douchebags do that. Get the right equipment and CHARGE $$$ for the use of that equipment, respect your tools and your labor. Be safe.

  12. I did tractor tire service work for a local truck stop that owns hundreds of locations. And I can tell you the LAZINESS AND STUPIDITY is very prevalent in this industry!! They talk a good game about safety but when it comes down to it its GET IT DONE AND SAFETY TAKES A BACK SEAT TO TIME SPENT DOING IT!!!

  13. If your inflating split rims ( spiders ) and no cage is available lay the tyre under the chassis of the truck/ trailer before inflating it…

  14. These 3 good men who worked to build our nations united civilization are remembered and honored for their service to the "BUILDER" are blessed with rest and given new life into forever. I give peace to their loved ones and joy to the truth that one day we are all united.

  15. I heard a story of a tire exploding throwing a worker onto a tire mounting machine impaling him through his back side

  16. My bro had a tractor tire blow up and broke his leg. Had a steel jig with six pins going thru his leg for 18 months, Lost about 2 inches of length on his leg. At least he lived and learned.

  17. Happen to My Dad, the tire blew the ring straight up, after breaking both his fore arms and wrist, and went thru the Roof, no safety cage
