Let’s say you finally go to the store and invest in an air compressor. You’ve heard how great air compressors are and how helpful for home improvement they are, and you have decided that, with all the home repairs on your “To Do” list, a compressor will come in handy. Once you bring it home, however, do you know what to do with it? How exactly do you plan to utilize your tank of pressurized air? Perhaps one of a variety of handy attachments will be just what you need to begin your home repairs.
First, invest in quick connect couplers and an inflation kit. Any tools you buy will require the couplers in order to be connected to the air hose, and if your kid’s bicycle tire goes flat or he’s dying to have his brand new pool toy inflated, you’ll be glad you bought the inflation kits.
Have you ever struggled to scrub away stubborn dirt from the wheel well of your car, or laboriously tried to wipe away all the dust and cobwebs from a piece of stored furniture? If so, a blo-gun is what you need to invest in. You’ll be surprised with all the uses you find for your blo-gun. Just be sure never to point it at exposed flesh.
A nail gun is another attachment never to point at exposed flesh; however, if you’re tired of wasting energy banging away with a hammer, let your air compressor do the work for you and invest in a nail gun. You could also use an air hammer or an air drill to do jobs around the house faster and easier.
An air stapler is an energy saving attachment much like the nail gun, and you’ll be surprised at what you can find to staple. Perhaps your roof needs re-shingling? A heavy duty air stapler may be the time-saving convenience that you’re looking for.
If you like to work on cars, an air ratchet wrench or impact wrench can make your job a whole lot easier.
Even if you don’t do body work on automobiles, an air sander and a sandblaster are attachments that can come in handy. Rather than laboriously scraping away old paint chips when you repaint your house, you could save time and the strength in your arm with an air sander or a sandblaster.
Once you start to actually paint your house, a paint gun may be just what you need to cut your labor time in half and improve the quality of your workmanship.
As you can tell by the aforementioned examples, air compressors start to look a lot less daunting and a lot more promising when you realize the time and energy they can save you if you invest in a few handy attachments.
There are adhesive dispensers that are perfect for scrap booking. These adhesive dispensers dispense adhesive squares, lines or dots. You can find an adhesive dispenser for any type of scrapbook need.
Vellum is a type of paper that is rather tricky when it comes to adhesives. Because vellum can be seen through you need to be careful when you glue it to something. If you do not use the proper adhesive you will be able to see the adhesive through the vellum and this is not attractive. Look for an adhesive made just for use with vellum and you will be able to use this specialty paper with ease and the final product will look lovely, too.
If you want to add dimension to a page you can use pop-dots or tape. This adhesive comes in various sizes and shapes and is thicker than regular adhesives. When you use pop-dots you can add buttons or other embellishments and they will stand out on your page. This is a great way to add interest to your scrapbooks.
There are also liquid adhesives and pastes that work for specific scrapbooks needs. When you are gluing paper to paper you will want a different adhesive than when you are adhering metal to paper.
At times you may need a hot glue type of adhesive. This kind of adhesive is usually in stick form and fits into a glue gun. Hot glue is good when you want to add ribbon or other fibers to your scrapbook.
As you can see there are many adhesives that you may need when you are interested in scrap booking.
1 This circular gives advice on the precautions to be taken against the toxic, fire and explosion hazards presented by refrigeration systems containing ammonia. These are most likely to be found by LA enforcement officers at cold stores and food distribution warehouses. It applies to the entire system not simply the compressor house. It provides interim advice on matters of concern to enforcement officers pending revision of BS 4434:1980.
2 Appendix 1 outlines the general principles of refrigeration, Appendix 2 gives information on the results of the programme of special visits carried out in 1983 by Factory Inspectorate (F1) to examine present standards in the food industry and Appendix 3 gives detailed guidance on electrical standards. Enforcement officers should not overemphasise the hazards of ammonia compared with other refrigerants.
HAZARDS
Toxicity
3 Ammonia is a chemically reactive gas that is very soluble in water and is much lighter than air (vapour density 0.59 of that of air). Cold vapour (e.g. from leaks) may however be denser than air. Although there have been incidents of exposure to harmful concentrations of ammonia in the UK there have been few fatal accidents. Ammonia is characterised by a typical pungent odour and is detectable by most people at levels of about 50 ppm in the atmosphere. Although workers become tolerant to this effect and in the past have been able to work without distress at levels up to 70 ppm, currently the recommended exposure limit for ammonia is 25 ppm, 8 hour TWA (0.0025%) and the short term exposure limit is 35 ppm, 10 minute TWA. At 400 ppm, most people experience immediate nose and throat irritation, but suffer no permanent ill-effects after 30-60 minute exposure. A level of 700 ppm causes immediate irritation to the eyes, and a level of 1,700 ppm (0.17%) will give rise to repeated coughing and can be fatal after about 30 minutes exposure.
Exposure to concentrations exceeding 5,000 ppm (0.5%) for quite short periods can result in death. Response to the effects of ammonia varies widely between individuals, and the dose-response effects described above are likely to be those experienced by the more susceptible members of the population.
Fire and explosion
4 Ammonia forms a flammable mixture with air at concentrations between 16 and 25% v/v. There have however been very few incentive explosions involving ammonia compressor houses in the UK and all of the reported incidents involved ammonia leakage from plant under maintenance. Existing guidance
5 Current guidance on the precautions which should be taken with ammonia refrigeration plant may be found in: British Standard 4434: 1980 Requirements for Refrigeration Safety: Part 1, General. The requirements (particularly from the f ire and explosion standpoint) are similar to those in the earlier (1 969) version. However a full revision of BS 4434 is taking place.
Precautions
6 Under normal circumstances people will not be able to bear ammonia concentrations at even a fraction of the flammable limit. The appropriate precautions are mainly those applicable against toxic effects in occupied areas and to work where sudden exposures are foreseeable, such as maintenance and repair work, including in particular filling and oil draining. Precautions against fire and explosion will be appropriate however, in unoccupied areas such as compressor houses and unattended plant such as cold stores where accumulations of vapour may go unnoticed.
PRECAUTIONS AGAINST TOXIC RISK
Respiratory protective equipment
7 Any person entering an area in which ammonia vapour is likely to be present at a significant level (eg for rescue or fault-finding purposes) must wear self-contained or airline breathing apparatus. This does not include routine visits to plant rooms etc. A suitable and properly maintained set should be conveniently sited close to, but outside, any area in which high levels of .ammonia vapour might arise. In no circumstances should anyone enter an area where a flammable concentration of gas may be present. Details of suitable apparatus are contained in Form 2501 Certificate of Approval (Breathing Apparatus), published annually by HSE. See also Guidance Note GS 5 regarding entry into confined spaces.
8 Suitable respiratory protective equipment must be worn by every person carrying out engineering maintenance work on any system where there is a risk of release of ammonia. Full face canister respirators with type A (blue) canisters give good protection in atmospheres up to 2% concentration or 20,000 ppm, for one hour. Work in such a concentration is likely to lead to discomfort quickly due to skin irritation as ammonia dissolves in perspiration.
A list of suitable equipment is given in form 2502 Certificate of Approval (Canister Gas Respirators). For substantial jobs impervious suits may be necessary if the gas cannot be cleared.
9 Everyone who is likely to need to use respiratory protective equipment must be properly trained in its use and must be fully aware of its limitations. The equipment must be maintained, kept clean and examined at least once a month. Appropriate records should be kept. If canister respirators are used there must be an effective system for deciding when the canisters should be renewed.
