INTRODUCTION

Belt conveyors are probably the most efficient means of

transporting bulk materials. However, they are considered

dangerous due to the sheer size of the installation which prevents

clear and unimpeded visibility down the length of the system.

Conveyors can be one of the most hazardous mine or plant

equipment installations if safety regulations are not strictly

followed or if the conveyors are not properly maintained.

The South African Mines Health and Safety Act (Act 4 of 1996.

Section 21) states that the onus is on the supplier to

provide the correct conveyor design taking into consideration

the risk to the health and safety of operating personnel.


PURPOSE

The purpose of this document is to serve as a minimum

specification for the design of safe operating conditions

and fulfilment of safety requirements for belt conveyors in

accordance with the statutory regulations and Acts

pertaining to machinery, particularly those sections

applicable to conveyors.

OTHER SAFETY ISSUES (SANS 971)

Fire resistant properties methods of testing

This standard is a critical issue from the industry and CMA

perspective Steelcord belting (SANS 1366)

Ply belting (SANS 1173)

Solid woven belting (SANS 968)

Fire resistant properties methods of testing (SANS 971)

SABS technical working group input complete

The standard currently needs to be issued by the SABS in

order for it to become official

Interrelated with the belting suite of specifications

Mine fires linked to conveyor belts

prompted development of

conveyor belt testing and

specifications

Build up of heat by

friction was, and still is,

the primary cause of fire

4 parameters usually

specified in safety

standards test

Conveyor belting and fire hazard in mining

CMA – SANS 971

4 parameters usually specified in safety

standards test

• Flame test - resistance to ignition

• Friction test - resistance to heat build up

through friction

• Flame propagation test - resistance to fire

propagation

• Electrical resistance test - resistance to

static discharge

Ignition test

Assess how quickly

standard size sample will

self extinguish after being

subjected to standard

flame.


CMA – SANS 971

Friction test - drum friction

Assess for fire, glow

and temperature rise

when subjected to

standard friction

conditions.


CMA – SANS 971

Fire propagation test - ‘full scale gallery’

Assess how much of

the standard sample

has no fire damage

after standard flame

has been applied for

standard time.


CMA – SANS 971

Fire propagation test - Test methods for Europe

• UK high energy test

4m long sample 1000mm width 7.5kg propane burned

for 50 minutes.

Test replaced by ‘equivalent’ mid scale test

• Belgium and France - 2m long sample, standard

energy burner. Still in use for textile reinforced belts.

For steel cord and aramid reinforced conveyor belts

high energy test used where 5.2kg propane burned for

20 minutes.

• Germany - very high energy burning, roadway test

(Brandstrecke test)

New fire testing standard for South Africa

SANS 971:2013

•This new testing standard likely to come into

force in September 2013.

•The same methods of testing will be applied to

all constructions of conveyor belting

•Existing drum friction test, electrical resistance

test and flame ‘initiation’ test to be retained with

minor changes.

•Addition of mid scale fire propagation test

CMA – SANS 971

Mid scale fire propagation test

Designed to achieve the

same results as full scale

test but with reduced

smoke emission to ensure

that the test can be

performed without

negative environmental

impact.
