The doctor will examine your eye, typically with a [http://en.wikipedia.org/wiki/Slit_lamp slit lamp]. You may receive some eyedrops to numb, dilate, or dye your eye to aid in the examination. Then, you'll probably get some eyedrops to take home, to help alleviate the pain or lubricate your eyes. In most cases, you should be recovered within a few days. | The doctor will examine your eye, typically with a [http://en.wikipedia.org/wiki/Slit_lamp slit lamp].

| − | + | ===MSDS (Material Safety Data Sheets)=== | |
| + | Material Safety Data Sheets are summaries of the chemical properties of any material. Employers are generally required to have them available for any material they use, and manufacturers and distributors will often include them when they ship a product. | ||
| + | |||
| + | MSDS supply important info to people working with various materials in an occupational fashion. For example, an MSDS for paint is not highly pertinent to someone who uses a can of paint once a year, but is extremely important to someone who does this in a confined space, forty hours a week, for decades. Serious hobbyists who use materials regularly should consult the MSDS. | ||
| + | |||
| + | *[http://www.ilpi.com/msds/ Where to find MSDS on the Internet] | ||
| + | *[http://www.ilpi.com/msds/ref/demystify.html The MS-Demystifier] | ||
| + | |||
| + | ===Personal Protective Equipment (PPE)=== | ||
| + | Personal protective equipment should be chosen and worn correctly when working with various chemicals. Standard fare when dealing with a majority of chemicals includes safety goggles (often used with a face shield), apron, and protective gloves that protect the hands and forearms, and possibly even a respirator. PPE should be chosen carefully to ensure compatibility with the type of chemical being used. | ||
| + | |||
| + | Do not use thinners or solvents to clean your hands or other body parts. Solvents and thinners do soak through your skin and into your blood stream. Many solvents and thinners are very toxic and could cause severe irritations, sickness or death. | ||
| + | |||
| + | ===Brake parts cleaner, welding, and phosgene poisoning=== | ||
| + | Phosgene, a deadly gas, may be produced when welding parts that have been cleaned with solvents containing chlorinated hydrocarbons, such as brake parts cleaner. | ||
| + | |||
| + | Phosgene was used during World War I as a chemical weapon. It is often not detectable, but may also smell like freshly mown grass or musty hay. | ||
| + | |||
| + | Phosgene is a combustion product of various common chlorinated solvents. It does not occur naturally. Ultraviolet radiation (like that created during welding) can convert chloroform into phosgene. | ||
| + | |||
| + | Phosgene is an irritant that damages the skin, eyes, nose, throat, and lungs. Symptoms of phosgene exposure include coughing, burning sensation in throat and eyes, watery eyes, blurred vision, shortness of breath, nausea, vomiting, and pulmonary edema. Delayed effects of phosgene exposure (up to 48 hours later) include difficulty breathing, coughing up white or pink fluid, low blood pressure, and heart failure. Long-term health effects of phosgene exposure can include chronic bronchitis and emphysema. | ||
| + | |||
| + | The effects of phosgene gas poisoning may not show up immediately, and may be cumulative over time, with multiple exposures. | ||
| + | |||
| + | By the time you can smell phosgene, you've already been exposed to a hazardous dose of it. Because of this, prolonged exposure to phosgene without intervention is possible. The OSHA permissible exposure limit to phosgene is 0.1 ppm (parts per million) averaged over an 8-hour workshift. Phosgene is considered immediately dangerous to life or health at 2 ppm. Because the odor detection threshold is 0.4 to 1.5 ppm, odor does not provide sufficient warning of harmful phosgene concentration in the air. | ||
| + | |||
| + | If you think you may have been exposed to phosgene gas, move outside or to fresh air. Phosgene gas is heavier than air, and will sink, so move to higher ground if possible. If your eyes are burning or your vision is blurred, rinse your eyes with fresh water for 10 to 15 minutes. Seek medical attention. | ||
| + | |||
| + | Those at risk of phosgene gas exposure may choose to wear [http://www.afcintl.com/gasdet/isocyanates/gmdbadge2.htm phosgene detection badges]. | ||

| − | ===Don't use | + | ===Don't use acid to clean concrete=== |
| − | Using | + | Using acid to clean concrete can crumble and flake your concrete surface. Acid doesn't actually "clean" concrete -- it '''dissolves''' it. The acid soaks into the concrete, and will continue to damage it until it is neutralized. Instead of sulfuric or muriatic (hydrochloric) acid, or any other kind of acid, use a commercial product specifically designed for cleaning concrete. |
| − | Water will dilute | + | Water will dilute acid to the point of being neutralized if enough water is used. Never add water to acid (remember the old chemistry class saying "do like you oughta, add acid to the water"). Always add acid '''slowly''' to water. In fact, sulfuric acid (and other strong acids) produces heat when it is introduced to water. The resulting exothermic reaction can almost instantly boil the water, blowing acid all over your body, leading to acid burns. |

| − | == Respiratory protection == | + | ===Bondo=== |
| + | Bondo, (a generic name for plastic body filler) was developed as a non-toxic replacement for lead. However, it still poses health risks. Gloves, mask, and sufficient ventilation are recommended when using Bondo. For more details, [http://solutions.3m.com/wps/portal/3M/en_US/MSDS/Search/?gsaAction=msdsSRA&msdsLocale=en_US search the MSDS database at 3M.com]. | ||
| + | |||
| + | ==Skin protection== | ||
| + | When handling hydrocarbon chemicals (oils, greases, solvents, paints, and thinners) use nitrile or latex gloves and/or skin protective barrier creams. Repeated and/or prolonged exposure can result in sensitization and possibly chronic skin or organ problems. | ||
| + | |||
| + | If using acids or any other harmful chemicals, use skin protection that's adequate for exposure to the substance in question. Not all rubber gloves are going to hold up to all chemicals, so use the MSDS or label instructions as a guide to proper protection. | ||
| + | |||
| + | ==Respiratory protection== | ||
Respiratory protection is probably overlooked more often than eye and ear protection, yet is every bit as important. There are many jobs around the garage in which some form of respirator or mask should be used. These include but are not limited to: painting, welding, grinding, sandblasting, handling solvent tanks, and insulation handling (especially when it contains asbestos). Respirators are often found in two basic styles: full face and half face. These should be chosen based on the level of exposure that is anticipated. Generally speaking, a half face respirator should be sufficient for most at-home projects. | Respiratory protection is probably overlooked more often than eye and ear protection, yet is every bit as important.

When spraying more than occasionally, the recommended protection is forced air or remote type system. Follow the MSDS and/or instructions that come with your material that you are working with.

Other heavy or awkward objects like axles or automotive bodies should be moved with high quality nylon (or even kevlar) straps that are free from cuts, frays, or tears.

Try to refrain from working under heavy objects. When this can't be avoided be sure to firmly support the load. When working under a vehicle that has to be jacked up, be sure to support the weight with jack stands or ramps designed to support the weight of the vehicle. Do not use the jack as the sole means of support. Always work on a solid, level surface and block the wheels to ensure the vehicle doesn't roll or fall off the supports. Make sure the jack/jack stands are designed to support the weight you will be raising. Unless on the road side, refrain from using a bumper jack as they are unstable and can push a car forward while jacking. | Try to refrain from working under heavy objects.
