  • Hitting against other structures or installations in the haulage during tramming.
  • Mistepping and tripping due to spillage during walking or leading the train.
  • Injury due low head room of box structures
cont safety risks
Cont. Safety Risks
  • Derailment of cocopan owing to faulty tracks and defective rolling stock resulting in injury to persons.
  • Restricted or confined areas in drive resulting in people being squashed to the sidewall by cocopan being trammed.
  • Self tipping of cocopan due to overfilling/overloading and uneven muck in cocopan
cont safety risks1
Cont. Safety Risks
  • Head, body and hand injuries from back rocking cocopan at tipping due to caked dirt accumulation inside of the cocopan.
  • Hands and feet injury caused by lifting of large boulders.
  • Detonation of old explosives in the ore/muck can result in death or injury.
5 2 health
5.2 Health
  • Respiratory complications as a result from tipping dry muck.
  • Skin contact with dirty water used for watering down broken muck may result in itching or irritation(Dermatitis)
  • Back injury or strains from improper lifting, carrying or pushing/pulling of cocopan.
5 3 environment
5.3 Environment
  • Contamination of air due to dust from tipping dry muck.
  • Ground and water pollution due to oil, and grease spillage from cocopans
  • Fire hazards from old timbers planks etc.
6 0 tramming procedures
  • Where ladder is provided use ladder to climb up to the platform.
  • Don't climb on cocopan as it can tip over
  • The box operator shall stand on the side of the chute at a safe position and not directly in front or at the mouth of the chute/box.
  • Ensure platform is free from obstructions
  • Chains used as weights to slow down the movement of the muck from the chute will belifted using a small 0.50metre hook and not by “ HANDS”.
cont tramming procedures
Cont. Tramming Procedures
  • Use correct size pinch/chute bars(have various length). Make sure you are standing in a safe place while manoeuvring rocks out of the chute.
  • No rock unchocking inside the chute with planks in open position. These could be a sudden ground rush as you poke resulting in injury as the pinch/chute bar ibeingjerkedupwards ”MOST CAUSES OF ACCIDENTS IN CHUTE/BOX TRAMMING ”.
  • Cocopan that don’t have the anti-tip lock mechanisms need to be firmly sprug on one side so that they don't tip when ground is being loaded.
  • There shall be good drainage in the tramming haulage especially under the boxes
cont tramming procedures1
CONT. Tramming procedures
  • Don't pull box/chute empty, but leave a fair amount of ground to cushion and that it is not a hazard to people passing underneath the boxes.
  • Take grab samples from each car that is loaded. Pick a handful from each of the four corners of the car and one from the centre. Do not select the samples. Clean the sample box at the beginning of each shift this will prevent contamination of the samples from the previous shift.
  • Use two long timbers(redwood) to block the chute, insert them on the slots in the chute. Do not use old drill steels.
  • Use a jack to lift de-railed cars and Sprugon the other side.
cont tramming procedures2
Cont. Tramming Procedures
  • If box/chute lip is lower than 2mteres from the tracks there shall be reflective strips on either side of that box/chute.
  • Cocopans or stationary rolling stock will be sprug on both sides of the wheels with the sprugingchains provided.
  • Cars will be pushed using the handles ONLY.
  • Hand trammers will sound their whisltes continuously while tramming(3 blasts repeatedly).
cont tramming procedures3
Cont. Tramming Procedures
  • Slow down at bends, junctions, crossings, switches/turn outs, area of congestion and the approaching to shafts.
  • Pans are to be cleaned thoroughly by blowing hammers are ‘’ NOT ALLOWED’’ to hit cocopan to remove caked dirt from them.
  • A mud rush is common in the cousin & Jack boxes where water from jack hammers goes into the boxes when there is little ore left in them allowing fines to cake above the ore forming a water sill that doesn't allow water to pass through. When you don't see the water coming first check before you open such a box. Report to your supervisors immediately.
7 0 blasting
  • Whenever there is a hang-up that needs blasting, a blasting licence holder will take all necessary precautions before initiating the blast.
  • Close all avenues leading to the box/chute to be blasted.
  • Sound blasting siren and place guards.
  • Ensure bomb is well secured to the bomb-stick and placed at the most effective position but away from causing damage to the box/chute and accessories.
  • Initiate and ensure all guards know the number of shots you have initiated and that they don't come until you have called them.

cont task procedures3
Cont. Task procedures
  • Ensure tracks around the grizzley are cleared of and blockages or rubble
  • Tip barricade to be installed in such a manner that they do not allow the cocopan to fall inside. Opening to be as small as possible to reduce the falling hazard to persons working there.
  • When tipping ground stand by the side of the cocopan to avoid its rocking.

  • Ensure safe footing do not permit a build up of rubble or fines on the grizzley bars.
  • Keep your working area clean and clear of any obstacles; ie large rocks and equipment at all times ensure you have a clear route at all times during the shift.
cont special precaution
Cont. Special precaution
  • Stop hammering until passer-byshave moved out of sight.
