Use: for Loading/Unloading of Tankers by Pumping
INTRODUCTION
Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapors or by combustible dusts. Explosions can cause loss of life and serious injuries as well as significant damage.
Background
Explosive atmospheres can be caused by flammable gases, mists or by combustible dusts. If there is enough of the substance, mixed with air, then all it needs is a source of ignition to cause an explosion. Accumulated static charges on equipment and tanker while solvents are handled, readily provides this third parameter.
Explosion can cause loss of life and serious injuries as well as significant damage. Preventing releases of dangerous substances, which can create explosive atmospheres, and preventing sources of ignition are two widely used ways of reducing the risk. Using the correct equipment can greatly help this.
The Dangerous Substances and Explosive Atmospheres Regulation 2002 (DSEAR) place duties on employers to eliminate or control the risks from explosive atmospheres in the workplace. A summary of those requirements can be found below.
This page does not deal with intentional explosives such as those used in demolition work or blasting in quarries.
An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric condition, in the form of gases, vapors, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture. An explosive atmosphere is an accumulation of gas, mist, dust or vapor, mixed with air, which has the potential to catch fire or explosion. An explosive atmosphere does not always result in an explosion, but if it caught fire the flames would quickly travel though it and if this happens in a confined space (e.g., in plant or equipment) the rapid spread of the flames or rise in pressure could also cause explosion atmospheric conditions are commonly referred to as ambient temperatures and pressures. That is to say temperatures of – 200C to 400C and pressures of 0.8 to 1.1 bar…
Many workplaces may contain, or have activities that produce, explosive or potentially explosive atmospheres. Examples include places where work activities create or release flammable gases or vapors, such as vehicle paint spraying, or in workplaces handling fine organic dusts such as grain flour or wood, classified as Zone-1.
Liquids
Liquids (such as petrol and other fuels) and solvents in industrial products (such as paint, ink, adhesives and cleaning fluids) give off flammable vapor which, when mixed with air, can ignite or explode. Flammable liquids are classed as:
Extremely flammable
Liquids which have a flash point lower than 00C and a boiling point (or, in the case of a boiling range, the initial boiling point) lower than or equal to 350C.
Highly flammable
Liquids which have a flash point below 210C but which are extremely flammable.
Flammable Dusts
Dusts can be produced from many everyday materials such as coal, wood, grain, sugar, certain metals and synthetic organic chemicals. A cloud of combustible dust in the air can explode violently if ignited.
Gases
Gases such as liquefied petroleum gas or methane. These are usually stored under pressure in cylinders and bulk containers. Uncontrolled releases can readily ignite or cause the cylinder to become a missile.
Solids
Solids include materials such as plastic foam, packaging, and textiles which can burn fiercely and give off dense black smoke, sometimes poisonous.
This manual provides complete information of installation, operation and maintenance procedures and instructions for operating Advanced Earth Interlocking System. Read this manual before attempting to install and operate EILS-TR-0418.
This manual contains essential safety information which supplements the safety features of the EILS-TR-0418. You must follow this instruction.
Each EILS-TR-0418 System consists of the following sub components or equipment:
EILS-TR-0418 is a system useful for controlling Static Electricity Discharges Hazardous areas in Bulk Drug, Chemical & Pharma and other industries handling inflammable liquids, solvents and explosive propellants. These systems continuously monitors Earth connectivity & prevents accumulation of static electricity and discharge during tanker un-loading and loading.
EILS-TR-0418 enables or disables power supply to existing transfer pump switching system. The pumps can only be switched “ON” manually for product transfer if the resistance to Ground (RG) from Tanker to Earth Connection is <= 10 Ohms. And the pump will be automatically stopped if there is by any chance Earth Failure or High Resistance is detected during product transfer.
The EILS-TR-0418 System continuously monitors the earth connection from Tanker to Earth Connection. It has RED, GREEN, YELLOW colored high bright LED indication systems indicating, clamp contact to tanker and earth loop check of less than 10 OHMS and STAND BY Mode RESPECTIVELY. Operator can be easily alerted to know the unsafe status of Transfer Process with this unique technology.
This unit is designed specially by incorporating Spark free switching mechanism works
With intrinsically safe ultra-low voltage & current feature. This system has highly sophisticated electronic sub-assemblies populated with high performance, long lasting and most reliable sub components from various reputed manufacturers.
The FLP enclosure meets industry standards, made out of Cast Aluminum with flame proof design, weather proof and certified by CMRI, Dhanbad. (Please find enclosed copy of certificate) and completely integrated unit is also tested for several Physical and Electrical tests like Burn-In test, Functional Testes, Mechanical Shock, Vibration, Drop, Dump etc. as desired by Industrial Applications.
The EILS-TR-0418 is a very important system wherever hazardous material is being transferred though tankers, bulk containers etc. this system has been designed in accordance
to the requirements of the industry studied and continual development over a period of 4 years.
The EILS-TR-0418 is user friendly System, very easy to install and operate and available for prompt delivery with additional accessories and alternative cabling solutions.
The EILS-TR-0418 ensures the highest possible levels of safe, positive earthing for road tanker during flammable transfer operations. Unlike conventional systems, the EILS-TR-0418 provides failsafe confirmation of the static earth condition using Industrial Grade Subcomponents and Electronics.
Modified version EILS-TR-0418 incorporates solvent tanker recognition system, i.e., the instrument switches on only when the clamp is hooked to stand alone tanker parked at unloading bay. The tanker body has typically 1000 to 5000 pF capacitance, and when the clamp is hooked to its body it takes measurement of this capacitance and if OK indicates with Green LEDs on top right and now is ready to operate as tanker earth interlock system. All other functions are as given above.
During unloading process, when S.S. hose is coupled to tanker and electrical power fails, the unit cannot be restarted. A special key operated magnetic switch is installed on right side of main FLP unit. By obtaining key from supervisory staff the system can be restarted.
On rare occasions if the solvent tanker is drenched due to heavy rains, the system may have to be started by magnetic key switch.
The above facility does not exist in other imported / indigenous models.
