2 WAS STARTED BY CARLOS BAHAMONDES MASAFIERRO ALTHOUGH SOLUTIONS SUCH AS THESE ARE NOW MORE IMPORTANT THAN EVER IN TIMES OF SEVERE DROUGHT, CARLOS BAHAMONDES MASAFIERRO STRESSES THAT WATERMIST SOLUTIONS ENSURE LONG-TERM SUSTAINABILITY LONG AFTER DROUGHTS HAVE PASSED. THIS IS ESPECIALLY IMPORTANT FOR A COUNTRY LIKE CHILE IN THE NORTHERN PART, WHICH EXPERIENCES AN AVERAGE ANNUAL RAINFALL OF +/- 20 MM, WELL BELOW THE GLOBAL AVERAGE OF +/- 70 MM, ACCORDING TO THE WORLD BANK. THE MACROMOLECULES FUNCTION AS AN ACTIVE SURFACE AGENT TO LOWER THE SURFACE TENSION OF WATER AND OTHER LIQUIDS. THE PROPERTIES OF THE LIQUID IN QUESTION ARE EFFECTIVELY MANIPULATED IN ORDER TO REDUCE THE MAGNETIC CHARGE OF THE CONSTITUENT PARTICLES, THEREBY REDUCING THE SURFACE TENSION. ON THE OTHER HAND, WATERMIST RESULTS IN WATER BEING ADSORBED FASTER BY SUBSTRATES. THIS SIGNIFICANTLY IMPROVES THE DUST-SUPPRESSION CAPABILITIES OF WATER, AS WELL AS REDUCING THE QUANTITY OF WATER NEEDED FOR EFFECTIVE DUST SUPPRESSION.

3 BY THE NFPA 750 DEFINITION, THE WATERMIST DEFINITION WATERMIST IS A WATER SPRAY FOR WHICH THE 99% OF THE TOTAL VOLUME OF LIQUID (DV0.99) IS DISTRIBUTED IN DROPLETS WITH A DIAMETER SMALLER THAN 1000 MICRONS AT THE MINIMUM DESIGN OPERATING PRESSURE OF THE WATER MIST NOZZLE. FOLLOWING THE CEN/TS DEFINITION, WATERMIST IS A WATER SPRAY FOR WHICH THE 90% OF THE TOTAL VOLUME OF LIQUID (DV0.90) IS DISTRIBUTED IN DROPLETS WITH A DIAMETER SMALLER THAN 1000 MICRONS AT THE MINIMUM DESIGN OPERATING PRESSURE OF THE WATER MIST NOZZLE.

4 WHAT DOES THE DEFINITION ACTUALLY MEAN THE DROPLET SIZE WAS IN THE EARLY WATERMIST STAGE SEEN AS AN IMPORTANT TOOL TO CATEGORIZE WATERMIST SINCE PEOPLE THOUGHT THAT DROPLET SIZE AND THE FIRE FIGHTING PERFORMANCE WAS CORRELATED. THEREFORE THE OLDEST STANDARDS AND CODES DIFFERENTIATED WATERMIST SYSTEMS DEPENDING ON THE SYSTEM DROPLET SIZE, AND DEMANDED THAT DROPLET SIZES WHERE MEASURED. THIS IS NOT THE CASE IN ANY UPDATED CODES AND STANDARDS, SINCE IT IS LONG PROVEN THAT ONLY FULL SCALE FIRE TESTING, AND NOT DROPLET SIZES, WILL SHOW WHETHER A SYSTEM CAN COPE WITH A CERTAIN RISK OR NOT.

5 LOW PRESSURE WATER MIST SYSTEMS THE SECURIPLEX WATER MIST SYSTEM IS A HIGHLY EFFECTIVE EXTINGUISHING SYSTEM THAT USES WATER AND AIR TO GENERATE A FINE WATER DROPLET. THE WATER MIST SYSTEM USES LESS WATER THAN STANDARD SPRINKLER SYSTEMS AND PROVIDES EQUIVALENT OR BETTER EXTINGUISHING CHARACTERISTICS THAN GAS BUT WITHOUT HAZARD TO PERSONNEL. SPECIFICALLY, THE WATER MIST S UNIQUE LOW WATER DISCHARGE THE WATER MIST SYSTEM USES LESS WATER PER DISCHARGE THAN ANY CONVENTIONAL SPRINKLER. POST-DISCHARGE CLEANING TIME IS THEREFORE NEGLIGIBLE AND CONSEQUENTIAL DAMAGES AND LOSSES ARE MINIMIZED. OPERATIONS CAN RESUME IN THE SHORTEST TIME POSSIBLE. HIGHLY EFFECTIVE EXTINGUISHMENT THE WATER MIST SYSTEM EXTINGUISHES THE FIRE IN SECONDS AND, UNLIKE GASEOUS SYSTEMS, IS HIGHLY EFFECTIVE EVEN THOUGH LIMITED VENTILATION IS PRESENT.

6 LOW PRESSURE THE SECURIPLEX FIRE SCOPE 2000 WATER MIST SYSTEM OPERATES AT A LOW PRESSURE OF PSIG WHICH ALLOWS THE USE OF STANDARD PIPING AND THE CONNECTION TO THE PLANT WATER AND AIR SUPPLY, WHEN AVAILABLE. THIS PROVIDES ALMOST UNLIMITED PROTECTION TIME AND ELIMINATES THE NEED FOR WATER TANKS OR BOTTLES. MAINTENANCE COST IS THEREFORE GREATLY REDUCED TWIN FLUID TWIN FLUID TECHNOLOGY USES LARGE WATER PATHWAY NOZZLES. MIST IS GENERATED BY AIR IMPINGEMENT AS OPPOSED TO SMALL ORIFICES THEREFORE MINIMIZING THE RISK OF NOZZLE CLOGGING. THE SECURIPLEX FIRE-SCOPE 2000 WATER SPRAY SYSTEM IS TYPICALLY SUPPLIED AS A FULLY INTEGRATED SYSTEM INCLUDING, CONTROL, DETECTION AND EXTINGUISHMENT, HOWEVER THE FIRE-SCOPE 2000 CAN BE INTEGRATED WITH AN EXISTING DETECTION SYSTEM.

7 WATER MIST TECHNOLOGY THE NFPA 750 STANDARD USES WATER DROPLET SIZING IN ORDER TO DIFFERENTIATE BETWEEN WATER MIST SYSTEMS AND OTHER WATER-BASED SYSTEMS SUCH AS SPRINKLERS AND DELUGE SYSTEMS. THE NFPA DEFINES WATER MIST AS: WATER SPRAY FOR WHICH 99% OF THE TOTAL VOLUME OF WATER IS IN DROPLETS WITH A DIAMETER LESS THAN 1000 MICRONS (DV0.99) AT THE MINIMUM DESIGN OPERATING PRESSURE OF THE WATER MIST NOZZLE. NFPA 750 ALSO IDENTIFIES WATER MIST SYSTEMS AVAILABLE IN MANY CONFIGURATIONS WITH VARIOUS CHARACTERISTICS AS SHOWN IN THE LIST BELOW. THE TIMES IN ITALICS ARE SECURIPLEX EXCLUSIVE.

8 NFPA 750 DEFINITIONS TECHNOLOGY Single Fluid Twin fluid atomizing OPERATING PRESSURE Low pressure (<175 psi) Medium press. (175 psi up to 500 psi) High pressure (>500 psi) NOZZLE TYPE Open nozzle, dry pipe Closed nozzle, wet pipe, fusible head DROPLET SIZE Class 1 droplet size (Dv0.90 < 200 MICRON) Class 2 droplet size (200 MICRON < Dv0.90 < 400 MICRON) Class 3 droplet size ( Dv0.90 > 400 MICRON)

9 LONG-TERM AND SUSTAINABLE SOLUTIONS WATERMIST IS A LEADING ENVIRONMENTAL SOLUTIONS COMPANY WITH A PRIMARY FOCUS ON SUPPLYING PRODUCTS AND SERVICES THAT ASSIST INDUSTRIAL AND MINING CLIENTS IN VARIOUS ASPECTS OF ENVIRONMENTAL COMPLIANCE. THE COMPANY IS WELL POSITIONED TO ASSIST ALL ITS CLIENTS NEEDS IN ENVIRONMENTAL MANAGEMENT REGARDING; DUST SUPPRESSION SOLUTIONS, WATER SOLUTIONS, ENVIRONMENTAL MANAGEMENT SERVICES, CARBON SOLUTIONS, AGRO-FORESTRY PRODUCTS AND FIRE SOLUTIONS.

16 MISTING SYSTEMS WATERMIST ALSO IMPORTS THE INTERNATIONALLY-RECOGNISED SCRUB MIST DRY MIST DUST SUPPRESSION SYSTEM, WHICH REMOVES RESPIRATORY AND INHALABLE DUST PARTICLES FROM THE AIR WITH MINIMAL WATER USAGE, AND NO COLLATERAL DAMAGE TO PROPERTY. IT WORKS BY ATOMISING WATER INTO MINUTE DROPLETS 5 MICRON (5ᵞM) TO 15 ᵞM IN SIZE, WHICH ARE ELECTROSTATICALLY ATTRACTED TO DUST PARTICLES AND FORM AGGLOMERATIONS THAT SUBSEQUENTLY FALL OUT OF THE AIR. CONVENTIONAL SPRINKLER SYSTEMS PRODUCE FAR LARGER DROPLETS OF BETWEEN 80 ᵞM AND 100 ᵞM. THESE COLLIDE WITH FAR LESS PARTICLES, AS THE AIR-STREAM PRESENT AROUND THEM DEFLECTS DUST OUTWARDS AND AWAY. WIND AND HIGH TEMPERATURES ARE ALSO FACTORS THAT NEGATIVELY IMPACT THE DISPERSAL OF DROPLETS PRODUCED BY CONVENTIONAL SYSTEMS, WHICH HAVE LOW KINETIC ENERGY AND ARE EASILY NEUTRALISED. BY INJECTING WATER BETWEEN LAYERS OF AIR MOVING AT SUPERSONIC SPEED, THE DRY MIST SYSTEM IS ABLE TO PRODUCE DROPLETS WITH HIGH KINETIC ENERGY THAT REMAIN UNAFFECTED IN THE HARSHEST CONDITIONS. AS A RESULT, SCRUB MIST UTILISES AS LITTLE AS 200 ML PER MINUTE, COMPARED TO SPRINKLER SYSTEMS THAT SPRAY MULTIPLE LITRES OF WATER PER NOZZLE PER MINUTE,.

18 EVAPORATION AND MANAGEMENT OF ACID MINE DRAINAGE AND ASSOCIATED POLLUTED WATER WATERMIST ENGINEERED AND MANUFACTURED DUST MONSTER (DM 40, DM 70 AND DM 110) MIST CANNONS ARE IDEALLY-SUITED FOR DUST SUPPRESSION IN OPEN PIT AREAS WHERE LOADING AND OFF-LOADING OF AGGREGATE OCCURS. IT IS ALSO SUITABLE FOR USE ON STOCKPILES AND ANY LARGE DUST GENERATED AREAS. THE DUST MONSTER RANGE OF MACHINERY MINIMISES THE EFFECTS OF DUST BY CREATING AN ULTRA-FINE MIST THAT ATTRACTS DUST AND ENCAPSULATES THE AIRBORNE PARTICLES, BEFORE DRIVING THEM TO THE GROUND. THE UNITS ARE FULLY AUTOMATED, EASILY ADAPTABLE AND PORTABLE. WITH A 30 KW MOTOR AND USER-DEFINABLE 359 DEGREE OSCILLATION, THE DM 110 BOASTS A THROW OF OVER 110 M ENSURING THAT IT IS DUST TRAPPING ATOMISED MIST HAS A COVERAGE AREA OF 2,9 HA. THIS IS ACHIEVED DUE TO THE HIGHLY-EFFICIENT JET FAN DESIGN, MANUFACTURED BY WORLD-LEADING JET FAN MANUFACTURER, MECHANICAL. WHAT S MORE, THE I-VAP RANGE OF MIST CANNONS ARE USED FOR EVAPORATION AND MANAGEMENT OF ACID MINE DRAINAGE AND ASSOCIATED POLLUTED WATER. THE LARGEST UNIT CAN EVAPORATE M 3 OF CONTAMINATED WATER PER DAY.

19 WATER MIST EXTINGUISHES FIRES BY TWO MAIN PRINCIPLES REMOVAL OF HEAT ENERGY FROM THE FIRE PLUME DUE TO VAPORIZATION OF MIST INTO STEAM. THE LARGE SURFACE AREA PER UNIT VOLUME INHERENT IN SMALL DROPLETS RESULTS IN A VERY EFFICIENT AND RAPID HEAT TRANSFER PROCESS. LOCALIZED DISPLACEMENT OF OXYGEN FROM THE FIRE BASE DUE TO THE PRODUCTION OF STEAM. WHEN WATER CHANGES INTO STEAM, IT EXPANDS BY A FACTOR OF 1650 TIMES WHICH CREATES AN IMPORTANT OXYGEN DISPLACEMENT AT THE BASE OF THE FIRE.

20 THE USE OF WATER MIST ALSO HAS CONSIDERABLE BENEFITS ATTENUATION OF RADIANT HEAT. SUSPENDED WATER MIST PARTICLES WITHIN A VOLUME WILL SCATTER RADIANT HEAT ENERGY FROM A FIRE, MINIMIZING THE RISK OF ADJACENT COMBUSTIBLES IGNITING. COOLING AND WETTING OF COMBUSTIBLE. WILL PREVENT THE RISK OF RE-IGNITION. SCRUBBING SMOKE AND OTHER COMBUSTION PRODUCTS FROM THE AIR. THIS IS IMPORTANT AS IT IMPROVES THE CHANCES OF A SUCCESSFUL EVACUATION AND SURVIVABILITY OF PERSONNEL. EXTINGUISHING CAPABILITIES IN VENTILATED CONDITIONS. EVEN THOUGH IT IS RECOMMENDED TO SHUT DOWN VENTILATION WHEN DISCHARGING WATER MIST, IN THE EVENT OF FAULTY LOUVERS OR OPEN DOORS, THE WATER MIST WILL STILL EFFICIENTLY EXTINGUISH FIRES AS PROVEN DURING THE FIRE MAINTAIN TESTING.
