  1. While many auto manufacturers are gearing up for the next wave of automotive revolution, to produce more electric cars (including PHV - Plug-in Hybrid Vehicle) in-lieu of gasoline / diesel powered vehicles, are buyers and local government agencies (e.g. LTA, NEA, SCDF, BCA, etc.) ready for this big wave, and I am not merely referring to the basic infrastructure concerns, such as charging and servicing facilities. As the title suggested, this thread is more for taking an in-depth view on Safety and Environmental concerns, with regards to sales, usage, servicing and disposal of electric cars (mainly with the batteries). For a start, I will just be touching on the following, while more topics will be added in due course. I would welcome all to share their thoughts, and relevant stakeholders to take a leaf out of this topic. 1. Batteries At the moment, there are 2 main type of batteries commonly used in electric / hybrid vehicles: i) Nickel Metal Hydride (NiMH) ii) Lithium Ion (Li-ion), which uses different cathode materials such as Cobalt Dioxide, Nickel-cobalt-manganese, Nickel-cobalt-aluminum, Manganese oxide spinel & Iron phosphate. NiMH is most widely used in automotive industries as it is relatively safe in term of raw materials use, during charging / discharging, and emit less harmful substances during a fire, BUT have a lower power density (typically about half of what Li-ion can do), meaning it will either have a shorter traveling distance, or take up much more usable space (and weigh more) if to maintain a certain mileage. Li-ion, on the other hand, while enable electric cars to cover hundreds of miles per charge (without taking too much boot or cabin space), are much more hazardous, in the way that it can have a run-away reaction (resulting in fire / explosion) when exceeded a certain operating / storage temperature (~60 °C), emit toxic gases and substance during a fire, so more awareness and precaution is needed. Due to the characteristics of these batteries, special considerations have to be taken during storage, handling and usage, such as proper ventilation (to prevent gas built up - Oxygen, Hydrogen, etc.), minimized risk of dropping / knocking (Li-ion batteries maybe be rendered unsafe if dropped or subjected to sever impact), means of safety cut-off (to prevent over heating, triggering run away reaction) and such. 2. Building Infrastructure With reference to the above, special facilities (with precise temperature monitoring and control, enhanced ventilation system, specific fire-fighting system and equipment) maybe required for storing large amount of batteries. Mixed occupancy, i.e. storage and workshop facilities under the same roof, have to be carefully evaluated, to identify incompatible activities, e.g. workshop may produce excessive heat / spark (ignition source) thereby increasing the risk of fire / explosion. Also, is the existing fire compartmentation for building (fire code, regulations) sufficient to contain battery fire? Li-ion batteries for example will continue to burn once it hit the auto-ignition temperature, and the only control is to cool the surrounding to prevent fire from spreading to neighboring premises / units. In the case of an electric vehicle fire within say a basement car park, building structure must be able to withstand the period of time when the batteries continue to burn, ventilation system to be able to effectively remove toxic gases produced, such as CO, Ni & Li vapor, and means of cooling provided to contain the fire. 3. Fire Fighting and Emergency Response Interestingly, the most commonly used dry power extinguisher is NOT going to work on Li-ion batteries. Beside using cat D extinguisher - for metal fire (which is not commonly available anywhere), the next best option is water, mainly to cool down the surrounding and lower the battery temperature (to prevent explosion). And for fireman, the protocol is to attempt fighting the fire ONLY WITH proper respiratory protection - full breathing apparatus (prevent inhalation of toxic gases / vapors). If you thing this is no big difference from other fire fighting attempts, you are wrong. Fireman will also have to adopt the proper procedure. One important step is to cut off the power supply to the vehicle. Tesla has done pretty well in detailing the steps to fight fire on it vehicles (through publishing Emergency Response Guides for vehicles in their lineup). And hopefully our fireman from SCDF, when deployed to handle such electric car fire, will be fully aware of these steps... And here is a video taken recently, when a team of firefighters in Austria was responding to a Tesla Model S on fire. Firefighters with full BA set (breathing apparatus) Firefighters accessing to power disconnection switch And the responsible shall be shared by the owner of electric car too. They have to be fully aware of what to do when their vehicle catch fire, and keeping the fireman informed of the key information, e.g. location of power cut off switch, battery packs, etc. 4. Servicing and Disposal of Batteries The onus shall be mainly on the workshop and dealer performing the job (provided the owner send their electric cars to the right place for the job). Beside safety concerns with the high voltage of the electrical system, proper charging and discharging process must be observed during replacement. For example, if the positive and negative terminals of the battery come into contact, short circuit will arise, followed by fire. On environmental front, proper supply chain has to be established, to ensure that the used batteries will be disposed in accordance to local and international standards and guidelines. And during the treatment process, again, the toxic material and gases have to be properly taken care of. T.B.C.

    Massive explosion in Lebanon

    Hopefully not an act of terrorism. Lebanese capital rocked by huge explosion https://amp.cnn.com/cnn/middleeast/live-news/lebanon-beirut-explosion-live-updates-dle-intl/index.html At least 78 people were killed in a massive explosion that shook the Lebanese capital, Beirut, on Tuesday evening, Lebanon's health minister told Reuters. The blast appears to have been centered on the city's port area. A CNN producer witnessed "chaotic scene" in Beirut emergency room following the explosion. Lebanon state-run NNA news reported that a major fire broke out near Beirut port and firefighting teams rushed to the scene and worked to put out the fire. Story developing.
  3. Loud explosions heard, thick smoke seen as fire breaks out in Jalan Buroh in Jurong SINGAPORE - Several loud explosions were heard as a fire broke out in Jurong on Friday (June 21). In a Facebook post, the Singapore Civil Defence Force said it had been alerted to a fire at 43 Jalan Buroh and that firefighting operations were ongoing. "SGSecure mobile app users of M1, StarHub and Singtel who are within the immediate vicinity of the fire incident would have received an advisory message urging them and members of public to stay away from the affected area," the post added. Reader Linda Cheng, 29, who lives in Boon Lay Avenue, told The Straits Times that she heard the loud explosions from her home around 5.20pm. She took several videos of the area from which the sounds were heard, which showed thick smoke coming from a building in the distance. There was also a strong burning smell in the area, she said. "We thought the loud explosions were thunder, until we saw the thick smoke," Ms Cheng said. Another eyewitness,who only wanted to be known as Mr Poh, told ST that he noticed the fire around 5pm. "I heard about 10 to 20 loud explosions," he said, adding that the explosions stopped after a while. "The fire looks to be under control, but there's still a lot of black smoke," he told ST at around 5.50pm. Mr Anthony Tai, who works in the logistics line, said he was at his home on Yuan Ching Road, about 4km away, when he heard multiple loud explosions shortly after 5pm. "I could see large, dark smoke from my window on the 10th floor," said the 63-year-old. A reader, who wanted to remain anonymous, took several videos of the fire from 47 Jalan Buroh, which is located across the road. There were people running out of the warehouse building when the fire started, he said. Photos circulating online showed the smoke could be seen from as far away as Jurong East, about 7km away.

    Mobile phone explosion

    what a way to go ... and as usual, the question on everyone's mind is : what phone ? Mobile phone explosion kills Malaysian venture capital firm's CEO KUALA LUMPUR: A mobile phone explosion led to the death of 45-year-old Cradle Fund Sdn Bhd CEO Nazrin Hassan, according to a statement released by the company on Friday (Jun 15). The company confirmed that the post-mortem report concluded the cause of death on Thursday as complications from blast injuries attributable to an exploding handphone that was being charged next to him. A message from the family that has been circulating on social media quoted Nazrin’s brother-in-law as claiming that at some point the phone had overheated and exploded, causing a blunt trauma at the back of Nazrin’s head and caused his death. The mattress too had caught fire but Nazrin was already lifeless by then, said the brother-in-law whose name was not mentioned in the message. Police had earlier said Nazrin was trapped in a bedroom fire at his double-storey terrace house in Mutiara Damansara yesterday and probably died of smoke inhalation. He had also suffered burns on his body. Nazrin leaves behind his wife and four children, according to the Star.

The blast occurred on 23rd Street between the Avenue of the Americas and Seventh Avenue. By JONAVIDOR/TWITTER on Publish DateSeptember 17, 2016. Photo by Louis Lanzano for The New York Times. A powerful explosion rocked the Chelsea neighborhood of Manhattan on Saturday night, injuring 25 people, shattering windows and forcing the closure of several blocks, the authorities said. None of the injuries were believed to be life-threatening, the Fire Department said on Twitter. The explosion was reported around 8:30 p.m. at 133 West 23rd Street, near the Avenue of the Americas, the department said, adding that there was a report that it emanated from a Dumpster. The authorities were unsure of the cause of the explosion and were exploring various possibilities. Mayor Bill de Blasio said at an 11:15 p.m. news conference that the explosion appeared to have been “an intentional act” but that there was no evidence that terrorism had been involved, although the investigation was continuing. The blast shattered windows in a five-story brownstone building and sent debris into the street, a law enforcement official said. The building is between a church on its eastern side and an apartment building under renovation on its western side. As a precaution, the police and fire personnel were searching trash cans for possible explosive devices, officials said.

    Brussels under attack!

    After Paris, now it's Brussels... http://www.bbc.com/news/world-europe-35869254 Brussels Zaventem airport blasts cause casualties5 minutes ago From the sectionEurope Media captionPeople fled Brussels airport after two explosions went offTwo blasts have struck the departures area of Zaventem airport in Brussels. The Belgian government has confirmed casualties but has given no numbers. The cause of the explosions is unknown. Another explosion has now been reported at a metro station close to the EU institutions. The whole metro system has been closed. The blasts come four days after the capture in Brussels of Salah Abdeslam, the main suspect in the jihadist attacks in Paris on 13 November 2015. Belgium has now raised its terror threat to its highest level. Brussels airport blasts - latest updates Emergency services are clearing the airport completely. Belgium's Het Laatste Nieuws reports that more bombs have been found. The airport is being evacuated and has been closed to flights. The Belga news agency reports that shots were fired and shouts in Arabic were heard before the two explosions. Media captionDamage at the departure lounge of Brussels airportImages on social media showed smoke rising from one of the buildings, amid reports of panic as people fled the airport. Rail transport to the facility has been halted and people have been told not to come to the airport. All flights have been diverted. Other reports say at least one of the explosions was close to the American Airlines check-in area but this has not been confirmed. The Belgian broadcaster RTBF quoted a witness as saying there were people injured or unconscious in the departure area, opposite the Sheraton hotel. There are few reports yet about the metro blast. Niels Caignau, a Swissport employee, told Flemish broadcaster VRT: "I was on a break and heard and felt a big explosion - we have from here a view over the departure hall and saw a plume of smoke come out. "The windows are completely shattered. People went outside in shock. It doesn't look good." Belgium's Interior Minister Jan Jambon had said on Monday that the country was on the highest level of alert for possible revenge attacks after the capture of Salah Abdeslam. He told Belgian radio: "We know that stopping one cell can... push others into action. We are aware of it in this case." Zaventem airport is 11km (7 miles) north-east of Brussels and dealt with more than 23 million passengers last year.

Photo: Reuters mail print View all 0 comments PUBLISHED: AUGUST 1, 3:41 AM UPDATED: AUGUST 1, 7:20 AM TAIPEI - An explosion caused by a gas leak in the southern Taiwanese city Kaohsiung has killed 15 people and injured another 243, Taiwanese media reported on Friday. Smoke with a “gas-like smell” was seen coming out of drains in the streets before the explosion, Formosa TV and the China Times newspaper said. The blast ignited huge fires and overturned and destroyed cars. Reuters photographs showed a scene of devastation, including the body of a dead or injured child on the ground among the rubble. Rescuers formed a chain to pull the injured from a deep crater in the road. The media said some residents described it as having felt like the area was hit by a powerful earthquake. The Kaohsiung government has set up an emergency centre, with a plan to send soldiers in to coordinate the rescue operation, the media said. The death toll was likely to rise further, they added.

    MH1438 minor explosion

    https://sg.news.yahoo.com/minor-explosion-engine-mas-flight-causes-panic-among-114621813.html Minor explosion on engine of MAS flight causes panic among passengersSmall sparks caused by an explosion on the left engine of Malaysia Airlines flight MH1438 while it was 20,000 feet off the ground, caused panic among passengers on board a flight bound for Langkawi today. A passenger with the user name Haswendy shared his experience and a picture of the plane engine on his Instagram page. He said the incident occurred 10 minutes before the plane touched down at the Langkawi International Airport. “I had a traumatic experience during our flight from KLIA to Langkawi just now. One of our flight MH1438 left engine had a light explosion that caused small sparks. Few of the passengers were startled and few were crying. “Alhamdulillah we landed safely,” said Haswendy, who was travelling with another friend. He said he was talking to his friend when he heard an explosion and saw sparks coming out from one of the engines while at the same time, the lights in the plane went off for a few seconds. He said passengers seated behind him were crying. The latest incident adds to the difficulty and pressure the airline has been having since MH370 bound for Beijing disappeared on March 8.
  16. A fire broke out in a third-floor eating house in Peninsula Plaza on Monday afternoon. It is believed to have been caused by a gas explosion in the shop selling Myanmar food. One man in his 20s was sent to hospital with burns to his legs. The Singapore Civil Defence Force said members of the public self-evacuated the building before their arrival, and that the fire was put out by an internal sprinkler system that was activated. The Straits Times found about 100 employees and members of the public gathered outside the building after the incident, which took place at about 12.40pm.

  24. http://www.firetrainingresources.net/items...pressedpics.pdf http://www.cleanmpg.com/forums/showthread.php?p=57346 The group of cars were set of fire by an arsonist. Only one CNG car was involved in this incident. This is a view of all the cars involved Another view from the rear A view of the left side of the CNG civic. Notice the lack of roof, truck lid, and how the doors are extended completely at their extreme points. This was a result of the explosion, not fire suppression efforts. Another view of the left side. In this picture you can see how the roof rails are bowed considerably from the force exerted on the car from the explosion. Also you can see clearly how far the front door was forced open. This is a picture of the rear of the car. The CNG tank was mounted towards the front of the trunk. For an idea of where that would be look at the spare tire, just a bit more forward than that. Another picture from the rear. Look at the metal bracket thats roughly sitting on top of the spare tire. Notice the U-bend clamps... those are the clamps that held down the CNG tank in the car. A picture from the right rear A picture of the right front. Notice the buckling of the hood from the pressure wave of the tank exploding. Its also pretty easy to see how much the roof pillars were blew out. A view from the front of the car. I think the fact that windshield washer fluid resivor was undamaged so exactly how much blast damage and flash fire there was to the car. The fluid in the container kept it from melting/burning. A closer view from the front. A picture of the trunk lid. This was blown approximately 75 feet from the car. That little blue CNG sticker on the back is the only warning that fire fighters have to tell that the car is powered by NCG. A picture of the roof of the civic. This was blow ~100 feet from the car. The screwdriver is there just for scale. A part of the rear of the car/bumper assembly. The actual rear bumper. Its sitting to the left and closer to the camera than the backhoe. Where the CNG tank landed. ~110-120 feet away. Another angle of where the tank landed. A view of the CNG tank fitting. It separated a small amount from the tank when the explosion occured. This is not where the failure of the vessel happend.... A picture of the CNG tank. Notice the delamination of the carbon fiber wrapping around the tank. These tanks are designed almost identical to the SCBA bottles we firefighters wear on our back. Another view of the extreme delamination due to fire involvement and explosion. A third view of the tank. A final fourth view of the tank. The hammer is there for scale. I think its quite obvious the extreme danger these vehicle types are when involved in fire. It is extremely dangerous to fire fighters as they are the ones that have to put out the fire when we are called to it, and often times it is impossible or very difficult to tell wether or not the car has such a tank in it.
