Q: 35 mph over a rocky tundra, but .02mph over a slight rise!: Being barefoot is not a fire hazard, but it does make it more difficult for you to get out of the building quickly and safely in the event of a fire or other emergency. If there is a fire, you're not supposed to stop for anything and that includes putting on shoes. That then puts you at greater risk of injury both inside (do you really want a third degree burn on your foot?) and outside, where you could step on glass or nails.

Q: I'm thinking of choosing alumina lightning rod. Is copper a much better choice?: Never ever use water in a kitchen fire. Invest in a fire extuinguisher just in case this REALLY does happen.

Q: Where do people park at the fire hydrant factory?: PLEASE DONT !! Fire Alarms save lives. Yours is obviously badly placed. Phone the Fire Service and ask them to come and advise. In Australia this is a free service they seem to love to do, and for seniors they will move it for you; for hard of hearing people they will make sure you have one you can hear without your hearing aids.

Q: Can I have your opinion on:?: may I suggest that you forget the PVC and go to iron pipe it will be stable and less sway and distortion and you can be assured of a very strong mast PVC pipe is never threaded and those parts that do have threads are street pipe type fittings

Q: I caught a glimpse someone wearing those orange traffic safety clothing running/fast walking out of my backyard when I was in the kitchen, I ran to my room which overlooks the front of the house and saw her walk straight across the street and speaking with people across the street in a plaza where it seems to be undergoing construction I noticed its a plumbing company since there are 2 vans blocking traffic in the parking lot where they are talking. Are these companies allowed to send people into other people's backyards without permission?: You can use a bike pump if its a small extinguisher. Usually I use a compressor at about 50 lbs. If you don't have one you can go to the gas station and use theirs.

Q: what is elastomer?what is resin?: The most dangerous part of a storm is the wind. Second is flooding if it rains enough for it to occur. Relax and enjoy nature's light show. The odds of being struck by lightning are very low. The purpose of the lightning rod is not to avoid or prevent lightning but to attract it. The idea is to control where the lightning goes rather than having it strike somewhere random. There is a slight danger of injury if you're in contact with appliances when the lightning strikes nearby such as upon power lines. Just avoid such contact during the storm.

Q: secure myself with a seat belt, have a car with air bags, safety glass, collapsable steering column, etc. And still pay outrageous insurance premimums, even though I have never been at fault in an accident. But people with motorcycles get to drive around with no helmets, no safety clothing requirements, loud pipes, and their insurance is nowhere near what I pay. I think their insurance should be ten times what a car owner pays. What do you think?: There is very little you can do without that ferrule (sleeve). They are very inexpensive.

Q: I was in the laundromat today and i saw two ladies wearing rubber gloves carrying huge plastic bags. and as i watched i noticed that in the bag were soiled bed sheets covered in vomit, urine, and feces.I cant think that this would be legal. Shouldn't it be a law that they must provide this service themselves? Without spreading the elderlies' waste throughout the population.: The easiest, and least expensive method would be to use white PVC plumbing pipe and fittings. You can use flange pieces to attach to a solid wood base, and assorted connectors to create shapes. Wood dowels can be inserted into the connectors, too. PVC is easy to cut and drill. It's so inexpensive, that you can experiment. The last time I bought PVC pipe, I believe that 10' sections were less than $2. Fittings are about .25 each or less. You would need PVC glue, also.just make sure that the glue is not exposed on the finished project, and totally cured before using. The other alternative is to hang a play fixture from the ceiling, and just lay a rug underneath. Then you wouldn't need a base. edit*** one other tipYou can weight down the base of the stand by filling the pvc pipe with sand before assembly.

Q: I'm making a door alarm, what MUST it have?I already have; low cost, easy to use, brightly colored/visible, not too small or big (to act as a deterrent)can you suggest some more please?: if the green is ONLY on the copper pipes, its oxidation and no worries.if its elsewhere, it could be mold and thats dangerous! use bleach to kill it.

Q: grooving 3 sch 40 pipe without go-no/go guage or vic ruler. wondered what the consequences could be? installing industrial air cond: Excellent thinking, turning bad news into a way of saving you money instead of just old shool thoughts of spending money for home repairs, it will soon be the year 2010 and we have better options than ever before.
