Lithium- Ion Battery Fires – Hydrogen Fluoride Detector

Gas Safety Risks: Lithium- Ion Battery Fires – HF (Hydrogen Fluoride Monitoring Systems)

Li-Ion batteries are now widely  used in mobile phones, electric vehicles, laptops including MW range of Renewable Energy Storage plants, aircrafts, submarines, mine-shafts and spacecrafts.

Gas Safety risks  in Li-Ion battery charging rooms:

• Li-Ion batteries when overcharged or short circuited are overheated and catch fires
• Li-Ion battery fires have caused great concern because of risks due to spontaneous fires and intense heat generated by such fires
• As a result of the above-said a lethal amount of toxic Hydrogen Fluoride Gas, HF is generated.
• HF from Li-Ion battery fires can pose severe gas safety risks in confined spaces like battery charging rooms, renewable energy storage plants in solar or wind power plants
• The electrolyte in Li-Ion battery is flammable and generally contains Lithium Hexa- fluoro -phosphate (LiPF6)
• In the event of overheating due to overcharging or short circuiting  and backed by high temperature, the electrolyte in Li-Ion batteries will vaporise liberating toxic gases like CO, CO2, HF (hydrogen fluoride)
• The moisture and humidity will further exacerbate the situation generating more HF (reaction of LiPF6 with water or humidity)
• Typical HF concentration expected can be as high as 20-200 ppm of HF (NIOSH/USA Safety limit , TWA:3 ppm HF, STEL: 6 ppm HF)

Solutions:

• Continuous monitoring of HF, Hydrogen Fluoride in toxic range of NIOSH/USA : 0-10 ppm
• Continuous monitoring of other toxic gases like CO, CO2 (gases generated due to  combustion fires)
• Continues monitoring of humidity and temperature
• VEFSA (Very early fire and smoke alarm)

Typical Systems:

• Single Point stand alone gas controller for HF, CO, CO2, Temperature, Humidity
• 1-4 channel HF, CO, CO2 Sensor/Transmitters with 4 channel Gas / PLC controller
• Warning alarm to plant people including GSM Alarm dialler capability to mobile phones
• DIGITAL MULTI-CHANNEL system for Renewable Energy Storage Plants for HF, CO, CO2, Temperature, Humidity
• Save 60-80 % costs on cable, cabling, installation with our DIGITAL SYSTEM

VEFSA: Very Early Fire and Smoke Alarm: For very early fire detection in electrical cabinets, switchgear rooms. Our sensing system is designed to pick up enhanced gas radicals which are liberated during overheating of PCBs, electrical insulation breakdown due to short circuit or earth fault, transformer insulation breakdown, again due to short circuit or earth fault. Please note  by the time the conventional fire detection system like VESDA or conventional smoke sensors  pick up the smoke, it is already too late. Our VEFSA Gas Radical Sensing System can detect the gas radicals and shut off the mains/power supply thus protecting millions of dollars of assets

Best CO (Carbon Monoxide) Detector & Alarms

Low Pricing, Best Technology, High Accuracy, Long Life, Carbon Monoxide Gas Detector and Transmitter .

Benefits of CO Monitoring:
The very early sign in coal handling/processing plant fire is liberation of gas radicals (CO predominant). The idea is to detect the presence of this CO gas radical for very early fire prevention. By the time smoke is generated and detected it is already too late. A typical CO monitoring system for detection of products of combustion fires or spontaneous combustion of coal fires can warn potential fire two days in advance then flame is present or detected. By installing an effective CO and CH4 monitoring system, coal based power stations can benefit in the following ways:

• Reduced insurance premiums
• Better safety to plant and personals
• Reduced down time
• Prevention of loss of resources
• Save time and money.

Why CO monitoring? :
Coal contains moisture which when liberated, coal gets oxidised, generating both heat and carbon monoxide. This heat when builds-up has the potential of creating spontaneous combustion of coal fires.
Coal is extremely friable and can be easily crumbled or pulverised. Further coal also generates coal dust needing extra preventive measures like proper maintenance of stockpiles, guarding against accumulations of coal in the fuel-handling system, compaction of stockpiles, cleaning spills and washing float dust. The most effective programme for fire-prevention would be to have Carbon Monoxide Monitoring and Control System
CO Monitoring Installation Aspects:
There will always be some safe background CO levels in coal handling or processing plants under normal operating conditions. These CO levels will rise during coal loading, handling and will again settle to normal levels once loading is finished and ventilation fans are running. It is important to find out the normal background CO levels by installing CO data-loggers and observing the CO generation trends under normal operating conditions of the plant. A typical CO level of 50 ppm of CO is normally present in background levels when coal is being handled, moved or transported. Based on these normal background CO levels the sizing/selection of the CO system (range etc) and alarm set points need to be undertaken.

Location of Sensors:
In general, it is wise practice to locate an adequate number of sensors at strategic locations based on knowledge of the potentials for ignition. When considering belt fires, sensors should be located in close proximity to drives, tail pieces, and main rollers.
When coal is the issue, any location where accumulation of coal dust or bulk quantities is likely or expected should be considered. These include belt transfers, crushers, dust collection systems, and storage bins (silos, bunkers, etc.).
System Approach:
A typical system may consist of number of CO (range: 0-300, 500 or upto 1000 ppm) and or CH4 (range: 0-100% LEL) gas sensor/transmitters installed remotely at strategic potentially risky areas. The 4-20 mA output coming from these sensor/transmitters can be connected to a multi-channel gas controller which can handle from 2 to upto 96 remote sensor/transmitters. When CO concentration levels rise beyond the set limit (say above 100 ppm, depending on safe background levels), the built in relay contacts will automatically generate audio-visual alarm for plant supervisor to take corrective measure (ventilation fans, mains shut-off etc).
