High Pressure Injection 06/10/29 256-162
2
Prelude To Incident
  • A Miner was assisting his partner was the
    operator of the Mclean Bolter.
  • The Miner was new to the bolter, he was currently
    working as a miner in a non mechanized heading of
    the mine bolting with Stoper and Jackleg.
  • The Miner did not have work in his particular
    area that day and was sent with the operator to
    act as helper for the day
  • The Miner did not have training in mechanized
    bolting through out his career.

3
How It Happened
  • The Miner was attempting to locate a hydraulic
    leak in a hose cluster with the power off.
  • The Miner pulled three hoses to the side and was
    holding on to a fourth and instructed his partner
    to energize the unit.
  • The hose that the Miner was holding was the hose
    that was leaking.

4
What Happened Next
  • The pressurized oil penetrated the Miners glove
    and was injected into his right index finger.
  • The estimated pressure exiting the hose from the
    leak was 3000 p.s.i.

What Happened Next
  • The Miner was not aware that the hydraulic oil
    had penetrated his finger and suspected that he
    may have received a splinter from the frayed
    metal in the hydraulic hose.
  • His finger then began to swell quite rapidly.
  • He and his partner then contacted his Supervisor
    and was transported to surface.

7
What Happened Next
  • The Miner was taken to the Medic Facility at site
    where the injury to his finger was examined, he
    was transported to Yellowknife NWT and then
    Edmonton Alberta for Medical treatment.
  • All during this time the Miner insisted it was
    not serious.

8
What Happened Next
  • The Miner arrived in Edmonton and underwent
    Surgery to remove any oil that had been injected
    into his finger.
  • The initial surgery was very extensive.
  • A initial incision was made from the tip of his
    right index finger through his palm extending to
    his right wrist.

9
What Happened Next
  • The Miner was kept in the hospital for one week
    after the incident.
  • His condition was monitored, and the prognosis of
    the finger was still unknown.
  • It was determined after the one week that the
    finger would have to be amputated to the second
    knuckle.

10
Extent of Surgery after the Amputation
11
Extent of Surgery after the Amputation
  • The Miner was fortunate that the extent of his
    amputation only included the finger to the second
    knuckle.
  • If the injection had occurred into his palm he
    would have lost his hand.

12
Factors Contributing to the Incident
  • Failure to warn The Miner and his partner did
    not identify the potential of such actions.
  • Failure to make safe The McLean Bolter was not
    in a zero energy state as per site requirements.
  • Improper placement The Miner was manually
    searching the cluster of pressurized hydraulic
    hoses with his hands
  • Improper placement for the task The Manufactures
    recommendation is for visual inspection only.
  • Servicing of equipment while in operation The
    request for hydraulic activation to locate
    damaged hose when the Miner was not certified to
    service or inspect equipment.
  • Failure to use appropriate PPE The operators
    manual states use a piece of tin or cardboard
    for inspection of hydraulic leaks.

13
Root Causes
  • Lack of knowledge The Miner had not received any
    documented training or been made aware the
    potential hazards associated with the McLean
    Bolter.
  • Lack of skill The Miner was not adequately
    trained in the use, operation and hazards of the
    McLean Bolter.
  • Inadequate Work Standards The company had at the
    time, no written procedures for the inspection of
    high pressure lines. There was at the time no
    mention in the company orientation of the risk
    factors when dealing with high pressure hoses and
    maintenance of them.

14
Hose Separator Tool
  • This tool was developed specifically for use on
    our mobile Electric/Hydraulic drills.
  • The tool is to be available for inspection and
    finding the location of leaking high pressure
    lines.
  • The operator is not to try to repair or remove
    any high pressure lines, this must be done by
    trained maintenance personnel.

16
Manual Update
  • Training manuals for all company equipment at the
    mine site have been updated with information
    outlining the hazards of High Pressure Injections.

17
Snap Lake SWP 87
  • A review and sign off of a Safe Work Plan on
    Checking for Hydraulic Leaks, is required by
    current employees and all new personnel arriving
    on site.

18
Out Come
  • The Miner will be off work for an undetermined
    amount of time. He has been subjected to
    extensive damage and surgery to his hand and
    finger.
  • He is currently attending Physiotherapy near his
    home in New Brunswick.
  • The pain and physiological problems that the
    Miner has endured will continue for some time.
  • In his own words, he could not believe that it
    would have become this serious
