  1. They were out of the 95's Ausi mask was shipped by Purolator. It may be handed to another Courier at the Border. You could get a tracking number by text or e-mail. Also sent a message off to the manufacturer for info. I store the 95's in Margarine containers and label the lid with a felt pen. Label the mask as well.
  2. Cloverdale Paint here has 3 white and 3 blue paper paint suits. I've used them, they have a zipper so can be reused if needed. I have to call, pay by Visa and make arrangements to pick them up. There are 2 other locations in the area. I've not called them yet. No N 95's or any other type.
  3. I'm finding out a little about the mask. There is an electrostatic charge induced by washing that lasts for about 50 hrs then needs washing and drying again. 1000 hrs then it's done. toss it and replace. I've swent of a request for info from the mfgr in Australia. He isn't seeing the light of day in production. These other guys were 21$ can more expensive than local firm. I'd like to see if they can be made under license like the V12 Rolls Royce Merlin made by Packard for Spits and Mustangs.in WW2.
  4. OK, I'm looking into what the Alpaca hair does. The boss is out but texted me he will respond when he returns. I'm trying another source. Maureen e-mailed me. Package goes out today.
  5. So, it is the way the hair is woven that brings the effectiveness down from .3 to less than .128? So it is the bouncing around in the weave that does the trick? Is this like a eggcrate type soundbooth where the noise gets absorbed with the convoluted shapes? I have some Home Depot filter material..less than 1/4" thick that could suffice as a backer for the hair and also serve as extra filtration. This is the same material used for the cold air returns on the roof mount heat pumps in the ceiling and the clothes dryer final filer....I'll send you a pic. So there is another firm I can contact as well as the owner of the firm these 2 were purchased from. I'll see what testing info they can provide without raising suspicion. My thoughts are can we duplicate the same results using the same or similar product. The 'weaving' may be the biggest obstacle. We have some Lamas 30 miles from here, maybe the owners can give me a couple of clumps. The rest of the mfg process is a snap. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- What are the properties of the gowns material? Are there other products that will achieve the same result? Again, fabrication isn't a problem. We have Quilting stores, Sewing machine stores. I personally know Dean Sawyer of Sawyer Sewing Center ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- RE ventilators, you and others here know all about these. Are they that complicated or are they made uber complicated. There are some vids on UTube I started to watch and will follow up. I'm pinched for time as I have to recertify for a certification. Can a simplified version be made with off the shelf parts. We have some Braniacs at UVIC who thrive on this stuff. They have developed a bandage with sensors that detects infection, ph or acidic levels. I think it changes color. Trying to catch it before infection gets away. Maybe it can be reverse engineered.
  6. There may be an oiler in the system for air tools. BTW, on my shop compressor we punched a hole thru the block wall and put the air intake outside. It made a difference in the noise level in the shop. Stay away from people, have the groceries delivered by the food market if that service is offered. Costs me 15 bucks a trip, order online or I go b/w 7 and 8 am like I said earlier. Costco is a good place to go for gas, their personnel wipe each pump each time it's used. That r go to a full service station where the employee pumps the fuel. I pack med gloves and hand sanitizer wherever I go. Full or half mask?
  7. Then build one. I'm not going to argue about it. The data can speak for itself, familiarize yourself with it. Here is a link to a Lee Valley Tools hepa filter. The specs are still only.3 micron. We need to get it to .1 or less, or fewer. https://www.leevalley.com/en-ca/shop/tools/workshop/dust-collection/filters/64681-hepa-filters
  8. Positive pressure could work to a point, however too much pressure and it would come out thru the path of least resistance. One being the top of the mask which could blow dust into the wearers eyes or if the air was high in humidity, fog up glasses. There are other N 95 type filters that have vents either at the very front or off to the side. I don't know if they are a 1 way valve like a chest seal or not but I was told that with normal use the vented ones were not as effective as non vented. Paint shops use a positive pressure helmet type device. Air comes thru a hose, probably going thru a dryer and filter. I'm sure that could be located on the Web. Maybe hook it up to the hospital o2 supply at something less than 15 lpm. Quick release air fitting.
  9. You may want to read up on these. They exceed the specs required. You wear the 95, I'll use this one as will my brother at the hospital. A good deal of the problem with the 95's is they are not worn properly. 75$ cn is not a cheap clone. Wildland firefighters are dying of heart attacks due to build up of carbon in the blood. Pics are on the way to ECRcarl@gmail.com
  10. I will pop it out of the Ziploc bac and post pics from different angles. These masks are worn for hrs at a time. The filter taken out, washed and a second one put in till the first one dries. The filter material is Alpaca hair. Evidently it doesn't 'scale' as some other products would. Wool balls up. Marino wool along with cotton are the fabrics of choice for WLFFing. These worn under the Nomex outers. No manmade fibes like polyprop, a hydrophobic material. We're told these can melt and stick to the skin....My own thoughts are if your clothes are melting you may have more serious things to worry about. Having said all that, from what I see some of the problems with the N 95 are they are not worn properly. The metal band over the bridge of the nose is not being pushed in to conform to the face. Doesn't matter if you wear a surgical mask over. The N 95 still isn't in contact with the face. I'd like to find out what are the properties this mask has that others don't....try to find a like product. What's so special about Alpaca hair??? What about LLama or the next doors standard poodle. Most of the mask looks like standard football jersey material with the holes. Stitching is nothing special. The rest of it looks like 'off the shelf' material. I'd like to reverse engineer it. Less waste. If the filter was replaced for each patient....would that deal with the 1 mask per patient visit issue. It would be quicker if I sent pics from my phone to your e-mail if that's OK?? I'll backtrack thru the rally info to find it. If you want one, I'll call the outfit, pay for it and have them ship directly to you...mail or courier, whatever you want. Mine has not been worn..It's still in the bag.
  11. I do FA and safety in a number of areas so get to see other options. In the shipyards we use a half mask with circular twist on filters, the filters are replaceable and the mask gets wiped out with BZK wipes. These particular masks will filter out welding smoke. I've had to stand by on fire watch and hole watch. I've asked for specifics but not heard back yet. You need to be clean shaven in order to get a fit test with them. The N 95's are supposed to be disposable but can last longer if stored properly. I used a margarine container and labeled it....most don't. A slightly better mask is the 'Fair Air' fire mask from Australia. Spendy, but I bought 2, one for me and the other for my brother who works in a hospital where there has already been one worker who has contracted the virus. This mask is re-usable and washable, also comes with an xtra filter. It takes out slightly more of the .3 micron particles....98.6% and 100% of the bigger particles. So I'm covered. We get them from a Logging firm up Island. $80 each or close to it. I shop for groceries b/w 7 and 8 am when the shelves have been freshly stocked including TP. Seniors and handicapped people only at that time. Having looked at the products involved I don't see the reason why it can't be reverse engineered. There isn't a patent on it yet. Could the same not be done with these ventilators?? Are there off the shelf parts that could be cobbled together to accomplish the same result.....Or in FA terms, 'was the objective met'. It may be ugly and unorthodox and not a streamlined and pretty as the current ones in use. If a camera could be put in the nose of a Maverick missile and fed back to the A10 in the first Desert Storm, there should be enough creative minds and skilled hands to pull this off.
  12. I've been doing this 'Smart on the deck business' for 8 years and had no issues so far except for operator error. I didn't see the post you referred to, so from my standpoint, that is your opinion.
  13. The Hoarders have overlooked the small hidden away drugstores or try a store that is open 24hrs and go just after they stock the shelves. Lots of Kleenex overlooked, pallets of it. Thrifty's opens to handicap and geriatrics 7-8 am. Maybe the Pres could order Michellin or Goodyear to start production on TP...12 or 16 ply.
  14. Chocks can be extended. The original car was 98" long, 2nd is 106" so I added a plate under and drilled, cut sloppy bolt holes. Rear chocks stay put. I don't use the front chocks any more, the modified ratchet strap is quicker and I don't have to worry about bolts going in crossthreaded or a 'helper' messing things up. Vice grips were just on for final adjustments. Loose end is normally wrapped around the belt.
