Hearted Youtube comments on Andrew Lam (@Lam) channel.

  1. I live in a mill building that was converted to apartments. There is very thick fire resistant material below each floor, and walls between units are double fire rated sheetrock on each side (which also greatly reduces noise). In my 1 bedroom apartment there are 10 sprinkler heads, and the building has a massive generator backed pump capable of running every sprinkler head in the building at full pressure. There has been an apartment fire while I've lived here, and aside from smoke that did get into common areas the damage was entirely contained to the one apartment. I feel very safe here.

  2. my dad's life was saved by a smoke alarm that woke him up in the middle of the night. firefighters said that if he was a minute slower to escape he would have been trapped by the flames. having a good smoke detector is important to me so thanks for the video.

  3. It's always a real treat to see a video from you in my sub feed :o This one was especially fascinating, and the time spent on your storytelling is felt really strongly Great narratives throughout

  4. Great video! It’s disappointing to see the video doing so poorly, YouTube needs more content creators like you! You’re one of only a handful of creators I have notifications on for.

  5. I knew you were going to talk about Philadelphia at some point. The city and its largest neighboring county, Delco, are both BELOW sea level and adjacent to the Delaware River. We've had heavy flooding in the past but it has improved significantly over the years. During hurricane Sandy the only thing preventing my house from being swept away was the genius engineering of the river right behind my property. I remember right after the storm sitting at the edge watching the water speed past what must have been over 30 miles an hour. In Ridley Park there is a gigantic recreational field called the "Hollow" that sits in a massive valley, with a small river at its bottom. Back in the 90s, according to my parents, the entire park used to be a lake. Now it's part of the genius engineering that keeps the area dry.

  6. I love how you dressed up for the occasion ❤😂

  7. After our house was broken into in 2018, we’ve put in tons of security. There’s a kick plate at the bottom of the front door, and the doors are solid oak. Even if the glass panels in the door are smashed most people wouldn’t be able to make it through. The next vulnerable spots would be the side or back door since both are made of glass. To help with that, there’s glass break sensors at every window and door and cameras all over the property.

  8. I love this, it's like watching "How it's made" but actually goes into the reason for each specific part of the product as well as giving a history lesson. You had my interest in the guard rail video but I'm definitely sticking around after watching this!

  9. I've had a Viofo dash cam for a couple of years now and it's a solid dash cam. I did have issues early on finding an SD card that would not fail. Once I put in a Transcend SD card, it's been flawless and very reliable.

  10. I mean, the older-gen ionization alarms ARE extremely annoying, but they've also saved my ass quite a few times because I live with roommates and have an electric coil stove and very little counter space. Roommate throws on a pot of water for Mac-n-Cheese, turns on the back burner instead of the front, tupperware catches on fire while I'm in my room with the door (right next to the stove) shut and they're in the living room watching TV or something. This happens about every 6 months or so but the detectors ALWAYS catch it within seconds of it flashing off, we just have to remember to open the kitchen door before anyone opens the oven otherwise everyone runs around to find some kinda pokey-stick-object to turn the alarm off. Hell, it ALMOST happened with a skillet full of bacon grease on the back burner LITERALLY LAST NIGHT, I just smelled it before it caught fire cause my door was open.

  11. Underrated af. This video shows the shift in the philosophy of stormwater management, from making the problem go away as fast as possible (conveyance), to holding them in place for as long as possible and not let it be a bigger problem down the line (retention). Interesting thing about Tokyo and storm management is that it goes back to the Tokugawa Shogunate period. Edo is very flat and prone to flooding and as such the shoguns started flood mitigation efforts even during the Closed Doors period. They rerouted the most of the flow of the upstream rivers into Tone River, and in part making it the longest river in Japan. Then in the Imperial era giant bypass channels with giant floodplains were constructed, which uprooted quite a bit of homes. Not to mention dams.

  12. Most channels covering Dash Cams go nuts over features. Thanks for being honest about pitfalls and what is really needed. 👍

  13.  @SadisticSenpai61  You are mostly correct as far as I know and hopefully soon you will be far less correct. The UK government, through a number of bodies, is reviewing building safety regulations right now, this includes Approved Document B, BS9991 and BS9999, with particular focus on tall residential buildings, and will be publishing more information over the next couple of years and the information coming out already is being reviewed by industry experts. Parallel to this, building fire safety is under review by major architectural/multidisciplinary studios and fire engineers. The new gateways for planning approval are already raising the standard of fire safety design and we will see the results of that in new builds as designers are now being held to a higher standard that the current standards and regulations, which is a little confusing for all, but will work itself out. The push for the ability for disabled residents to easily be able to evacuate a building without assistance is also making a difference, in particular with the New London Plan in regard to evacuation and fire lifts, although these high standards are also being applied to other projects in the UK. And on top of that there is the new standards coming out for the recording of fire safety information following the Golden Thread and including that in digital construction information, digital construction/BIM models coming from fire engineers, and the new addition of FIREie coming soon, which is similar to COBie BIM information, but for fire risk management. I could go on, but my comment is getting pretty long already. TLDR: Stuff is happening and the standard for fire safety is being improved in the UK in every way that the industry can think of.

  14. I can't express how much I appreciate your high quality, unbiased and professional reviews. Respect! Kudos!
    66
  15. Andrew : there aren't many channels on YouTube producing video ls at that level of quality, being entertaining and so informative. Clearly you are putting a ton of time into this. There should be a way to support your work with a bit more than just a subscription...
    64
  16. A great and informative video, Andrew! Great job!

  17. Other aspects of your video I’d like to comment on: Sprinklers Sprinklers are, as you said, an additional layer of protection. Without other measures like working compartmentalization, their effectiveness is limited, at least in a residential setting. External insulation External wall insulation, like styrofoam based cladding, can be a risk in high rise buildings, if it doesn’t respect the compartmentalization and spans multiple units without fire breaks. The most prominent example of this is Grenfell tower, which did prompt further investigation and updates to fire codes and procedures world wide. All in all, a fantastic video with well researched information. I loved that you linked additional resources in the description. Thank you!

  18. Is this the same guy who did the video about traffic safety barriers a few years ago? One of my all-time favorites.
    60
  19. I work for a big city FD and the biggest problem we have in appartement buildings (low and high rise) is people wedging fire doors open or interfering with the automatic closing systems. It basically bypasses all the protection of a fire break and spreads smoke everywhere. It's more common in poorly maintained buildings often owned by slumlords but I've also seen it in public housing and expensive condo towers. Only a few days ago we ran a 3am call for a small trash fire in the basement garbage room of a 4 floor 60 apt building, all the hallway and stairs fire doors were jammed open so though the fire was small and never spread from the room, all the stairwells and hallways were filled with smoke. It happens too often.

  20. Cool video. I'm definitely in the "you get what you pay for" camp when it comes to tires. More expensive brand name tires may hurt more now but they can literally save your life when it comes to handling and braking performance.

  21. You did miss one thing, the lack of crash compatibility tests. Not Just Bikes mentioned it in his video about trucks but it goes a bit further than that. As big trucks and SUVs get more popular these crashes will also get more common, in effect making smaller cars even more unsafe through no fault of their own. And it is not just cars either as Semi-trucks also have the same problem, the small clip at 13:36 shows what could happen. I do not remember where I saw it but this is still a flaw in modern trailers as most of those crash bars are not tested to be able to hold back a crash and the height on most of them are too high to be of any use to small cars.

  22. You've been knocking these info/story videos out of the park, amazing work again.
    58
  23. You can just tell how much thought and planning has gone into this video before he even touches a camera. Really high quality stuff, I cant wait to see more!
    57
  24. I'm a collision repair tech and you would be surprised at how much engineering goes into crash safety, also many of the very first safety features ie. Three point seat belts, proper headrests and even backup cameras, were introduced by Volvo who had their own safety design division in the 50s! They were also kind enough to not patent the designs allowing other manufacturers to use it for an easy safety increase thus creating a universal standard without having to enforce it (at least initially). UHSS was a big step in the right direction for passenger safety ensuring the safety cage is massively stronger than the rest of the car, and I'm glad more and more people are getting to see this stuff online. Also keep in mind Your Airbags NEED Maintenance Every 10 Years! On a side note being a car enthusiast myself I have to say, if you are going to modify any safety equipment, please replace it with something of equal or greater protection capabilities. For example replacing seatbelts and airbags with a cage and harness, even the pro's crash but the pro's are driving cars designed to crash at 100+ mph and be fine, your 30 year old miata would fail 90% of current test standards and wouldn't hold up well to a new F-150.

  25. A good video but I don't think you mentioned how the rubber itself has changed and improved over the years too(?) For example, all-season tires weren't a thing several years ago but now with improved rubber technology/compounds you have tires that can perform well all year round in summer and winter conditions. Like dedicated winter tires, all-season tires are certified for winter use by the mountain snowflake symbol on the tire sidewall.   Where I'm from with milder winters I think all-season tires are a good choice, and I have them on all my cars. In cold and wintry conditions the handling and safety is improved when compared to using summer tires all year round (which most drivers in my country still do). Obviously for places with harsher, longer winters you will get better performance by swapping between two sets of tires (summer and winter tires). Also maybe if you drive a sports car, and want optimal performance, then you would probably want to swap tires according to the conditions too. And I totally agree tires should be tested over an extended period of time, and not just when they are brand new and supple. I remember suggesting this on one of the popular youtube tire review channels a while back. Most of us will use a set of tires on our cars for a few years. Over that time not only does the tire pattern change but with weathering, sun light etc the characteristics of the rubber itself changes (often hardening) which affects the performance of the tire too, especially in cold conditions.

  26. I want to see a video on how to hide cables for rear dash cams. Thinking about grabbing an a119 to watch my back.

  27. New viewer here. Great video. Thank you. Back in 2018 my refrigerator power cord was pinched, causing a smoldering fire in the kitchen while I was at work. I had left an exhaust fan in one of the bathrooms going, and a passerby saw it and called the FD. No one heard any smoke alarms going. Glad I wasn't there, asleep.

  28. Holy crap! So much work went into making this video. I love how you compare wifi file transfer speeds. I use the Anker ROAV and Vantrue X3 dash cams and they take AGES to download via wifi. Anker offers a really awesome view of your speedometer and map feature when playing back via wifi.

  29. I was an early adherent of radial tires, having Semperit Supersports on my 1962 VW Beetle in the mid 1960s. Because of this or that I had the fronts mounted a week or two before the rears. The difference in those weeks was incredible. After all four were installed the difference was phenomenal. I never went back. If you ever drove a Beetle, you know how wiggley its read end was.
    47
  30. Hahaha, saw and thought the same thing. I liked the simple overview of the video. Recommendations are hard to make without a huge amount of research.
    46
  31. This feels extremely professional, it’s clear you took everything you’ve learned over the years and tailored it into a much more broader reaching category of topic. It works perfectly! Absolutely love it, definitely earned a subscriber!
    44
  32. I think your car gets dangerous when you crash, so I personally don't crash my car.
    42
  33. The quality and depth of consumer information as well as the production value of these videos is incredible! You need to consider something like a patreon link for us to give back.
    41
  34. Hi Andrew, I'm a fire alarm technician in Florida. I have to say you did your research on this and your information was flawless. I take my job very serious knowing that lives could be at stake. A big part of fire saftey is knowing what to do when there is a fire present in the building that a individual is at. I hope your videos reaches way more people.
    36
  35. This guy is SO good. I depend on his thoughts on dash cams.
    35
  36. Important note: outlet testers in the US usually can't check if your ground circuit is actually wired correctly! They usually just look for a connection between neutral and ground, because, as mentioned here, the two are actually connected (usually). So, if skimping builders just wired the ground of an outlet to neutral instead of doing things properly, everything will appear good... but you won't have the same protection as with real grounding.
    35
  37.  @Lam  that barrier video was amazing and so is this one! You really have talent for this👍
    35
  38. Its unfortunate the approach to the weight issue is having a minimum weight. A better solution that solves lots of other problems would to have a maximum weight instead, or better alongside
    34
  39. Based on your review I purchased Viofo A129 Duo system and couldn't be happier. I researched and researched for nearly six months, and your video stood out as the best review for my budget and driving needs. Thank you very much for your excellent work.
    33
  40. After 3 months of driving with A119 v3, I can really recommend it. Great quality! PS. Don't forget to buy CPL filter ;) Worth having!!
    33
  41. Takes time to produce such high quality videos. I'll wait

  42. Love the demonstration of how the seatbelt elements work. I didn't realize how complicated modern seatbelts are. All but one of my cars are 40+ years old, so they have really basic seatbelts that are either basic ratcheting mechanisms or just straight up straps that you set the tightness manually.
    29
  43. Thank you for your research!
    28
  44. And most people take them for granted, I love learning about things like this!
    27
  45. Shout out to the Manning Formula! As a young civil engineer 35 years ago, I was given a circular slide rule that was based on the Manning equation and it was so intuitive to properly size storm pipes — and is just as handy today even with the proliferation of computer software.

  46.  @Lam  We are trying to release a beta version before Chinese new year, also we will check the card statue notification.

  47. This is the first video I've seen of yours and it's excellent! It's easy to ignore the small details in the engineering of products which make a huge difference in performance. Your discussion about the design and implementation of siping brings to light one of the many seemingly minute differences which make a big difference in performance and, by extension, safety. Consumers should be aware of compromises made in designs balancing cost and performance. Thanks for the great video. Keep up the good work!
    26
  48. Have been pulling my hair out as to why my Blacksys CF-100 was having progressively worsening problems with the Sandisk Ultra SD cards, and now I have the answer! Many thanks! I had no idea that SD cards actually wore out.
    25
  49. YESSS new Andrew Lam vid!

  50. One of the reason you had a more efficient research in crash-tests is also the technological progress of simulations. while you will always need physical, real crash tests, the advancements in simulated material behavior helps saving a ton of money as (just for a rough example) instead of crashing 100 cars, you only crash 20 to get to satifying, in-charts results.
