2 The measures to be taken by the employer in terms of the regulation

above must include measures to ensure that:-

2.1 Where pedestrians have to be present that these pedestrians must maintain a safe

perimeter as determined by the mine risk assessment. When pedestrians are within an

unsafe perimeter from the trackless mobile machine, warning should be given to both the

operator and pedestrians. In the event where no action is taken by either to prevent

potential interaction the brakes of the trackless mobile machines must be automatically

applied. The system must fail to safety without human intervention.

This system must not remove the control from the driver; it must only take over when the

driver does not react.

2.2 Collision between different trackless mobile machines is avoided by a warning system to

both operators and in the event where no action is taken by either operator to prevent such

collision that the brakes of both trackless mobile machines be automatically applied.

2.3 Where trackless mobile machines run uncontrolled measures must be in place that will slow

down the trackless mobile machine.

2.4 Roll over Protection for trackless mobile machines shall be provided where required as per

risk assessment.

2.5 Trackless mobile machines shall be equipped with canopies to protect operators and

passengers from falling objects.

2.6 Measures must be put in place for operators/passengers of trackless mobile machines to

alight safely during an emergency situation.

2.7 Safety belts shall be installed and used on trackless mobile machines.

2.8 Functionality of all brakes on the trackless mobile machine shall be tested and recorded

prior to putting the trackless mobile machine into operation.

2.9. Measures must be put in place where practical possible to eliminate or manage blind spots

where required to improve the operators vision.

2.10 Fatigue monitoring to be used on heavy equipment such as haulers to monitor the

condition of operators on duty.

2.11 Underground Battery Charging Bays shall be equipped with the following:-

Floors that will prevent saturation from acid spillage

Task team meeting: 8 February 2013

ventilation

Fire fitting equipment

Ventilation interruption to the power supply connected to the battery chargers

Explosion protected lights to prevent hydrogen ignition.

Water supply for emergency acid spillage removal from persons.

2.12 Diesel Refueling bays shall be equipped with the following;-

Floors that will prevent saturation from spillage

Thru ventilation

Fire fitting equipment

Fuel leak free filling system

Lights

2.13 Tyres

When tyres are repaired on the mine by the mine or a contractor on the mine site the

following will apply

A Cage used during inflation to prevent injuries to persons

An adaptor on the hose that can be remotely released after inflating is complete

whether in the cage or on a trackless mobile machine

The dangers of gasses emanated from tyres..

The use of nitrogen in tyres

2.18 Safe Access

Trackless mobile machines must be so designed that persons required getting on and of trackless

mobile machines can do so safely without injury

2.19 Visibility.

Trackless mobile machines must be visible to pedestrians as well as for the operator to be able to

function properly

2.20 Locking out

Authorised use

Operators must be able to lock-out the source of supply on the trackless mobile machine and be in

procession of the key.

Unauthorised use

One or more competent persons doing maintenance, modifications or repairs on the same

trackless mobile machine must be able to lock out the trackless mobile machine

independently by utilising a scissors plate on the mechanism provided

Competent persons must ensure that all stored energy is released before locking out the

trackless mobile machine

2.21 Remote Control trackless mobile machines

Task team meeting: 8 February 2013

When frequency controlled in a coal mine when supplied from a cap lamp battery the cap

lamp must comply to the SANS 1438 standard.

Locking out on the remote unit is unacceptable.

One remote unit operating two machines in one section is unacceptable

2.22 Machine automation

2.23 Trailers

o Trailer coupling and uncoupling must be able to be done safely without injury to

Prior to putting into operation, each operator operating trackless mobile machine must have a pre-use checklist that was completed with pre-established criteria under which the TMM may or may not be put in motion

The operators supervisor must sign such pre-use checklist at least through the course of the shift.

2.29 The reversing over the berm of a dump or the edge of a stockpile;

The reversing over the berm of a dump or the edge of a stockpile shall be prevented by (i)

supervising the trackless mobile machine to the berm or edge or alternatively (ii). By

stopping at a distance determined electronically and then automatically apply the trackless

mobile machines brakes.
