1. High Voltage Safety Precautions
These rules, teamed with the idea that voltage shows no favoritism and that personal caution is your greatest safeguard, may prevent serious injury or even death.

2. Clogged Drains
Using a crystal or liquid drain cleaner sure beats calling a plumber every time your sink is stopped up. But, helpful as they are, drain cleaners can be dangerous if not handled carefully. There are three types of commercial drain cleaners: acid-, caustic- and solvent-based. Acid-based cleaners are usually sulphuric acid. Caustics are mainly caustic soda (sodium hydroxide) in either liquid or dry crystal form. Because of differences in concentration and secondary ingredients, the performance of caustic cleaners is more variable than that of acid cleaners. Solvents are milder compounds based on pine oil. Such substances as bleach (hypochlorite), sodium nitrate, aluminum salts, detergents, and chelating agents (organic compounds that break up solids) are often added to caustics to boost the decomposing action. Acid-based cleaners work best on all types of clogs. Of caustic cleaners, crystal-based ones are better for kitchen clogs (greasy, leftover food, for example). Drain cleaners are a straightforward hazard. The Hazardous Products Regulations demand that drain cleaners be clearly and prominently labelled with hazard symbols and warnings. Depending on its concentration, a drain cleaner must be labelled CAUTION, WARNING or DANGER, both in bold letters and in symbols. Despite the obvious fact that all drain cleaners are sufficiently poisonous to cause considerable damage, POISON warnings are not required by law. Most brands put the case obscurely, warning that the substance is "harmful or fatal if swallowed" Drain cleaners must also give appropriate first aid instructions, itemizing the ingredients, hazards, burn treatment and antidotes. Child resistant caps are one method of discouraging little ones from sampling these poisons. Manufacturers are permitted to market one size of drain cleaners without such a cap as long as another size is available with a child-resistant cap. The containers without child resistant caps must be clearly labelled "This package is for households without children". Warning labels aside, people simply don't take drain cleaners' toxicity seriously enough. Children are the usual poison victims, but adults often suffer skin burns from these corrosive compounds, and eye damage is easily incurred. Consider manual alternatives first. A rubber plunger is remarkably effective. You can get better suction by putting a bit of Vaseline around the contact edge, and filling the sink with hot water gives the tool a better grip. If the plunger doesn't work, you can try a plumber's snake. And the final manual alternative is to dismantle the plumbing to get at the trap — the curve in the pipe. (To avoid disaster, bail out the sink first and put a bucket under the trap.) When you do resort to a drain cleaner, follow its instructions closely. Don't use the plunger or do anything else that might splatter you with the caustic solution. After using drain cleaner, if you have to use a plunger or dismantle the drain, wear rubber gloves and eye protectors. • Don't mix your chemicals. It may seem the drain cleaner plus a little bleach or ammonia will do the trick. However, such combinations can kill you with toxic fumes, and some will explode. • Don't use drain cleaners in the toilet or garbage disposal. They're not up to the high heat produced. • Keep the local poison control centre and hospital phone numbers posted close to the telephone. • If you have children, keep all toxic chemicals out of reach. Read the contents and first aid instructions when you buy the drain cleaner, and keep the information handy — labels are sometimes obscured by drips. Buy only those brands with child-proof caps. • If an accident does happen, follow first aid instructions; take the container and the label with the victim to a poison control centre or to a hospital. What's a Drain Cleaner? • Sodium hydroxide: Also known as caustic soda or lye, it is strongly alkaline. Mixed with water, sodium hydroxide produces considerable heat. Toxic effects: Ingestion causes immediate burning pain in the mouth, throat and stomach; swelling and detachment of the lining membranes. Vomiting and diarrhea may occur. There is intense pain, a drop in blood pressure, cold clammy skin and a rapid feeble pulse. Stricture of the esophagus may follow. In severe cases, circulatory failure, esophageal perforation and peritonitus or pneumonia may follow. First aid: If ingested, give large volumes of a 1:3 vinegar and cold water solution, or give copious drinks of lemon juice. Don't encourage vomiting which will further damage the in testinal tract. Soothing liquids like milk, egg white or liquid paraffin can also be given. Keep the patient warm and get to a doctor in case circulatory failure occurs. External burns (skin or eyes) should be irrigated with cold water, then with a 1:3 solution of vinegar and water. • Sulphuric acid: When it dissolves in water, sulphuric acid produces heat and is very corrosive due to its dehydrating action. Toxic effects: If ingested, severe pain, violent vomiting of blood and stomach contents occurs almost immediately. Foamy mucus appears in the mouth — first white or bloodstained, later yellow or brown. Vomit often has a characteristic "coffee grounds" appearance. Corrosion and perforation of the stomach as well as stricture of the esophagus occurs. Contact with the skin or eyes produces severe burns. Inhalation of vapour may cause serious lung damage. First aid: Ingestion — do not encourage the patient to vomit. Administer milk of magnesia or soap solution to neutralize the acid. Soothing substances like milk, egg white or olive oil can also be given. Don't give sodium bicarbonate, which will liberate gas and increase the possibility of stomach perforation. Take the patient to a doctor for treatment of pain or possible circulatory failure and for administration of steroids to reduce inflammation. External burns should be flooded immediately with water and covered with baking soda or cold packs soaked with baking soda and salt solution. Eyes splashed with acid should be flushed with a steady stream of water for 10 to 15 minutes, holding the eyelid open. • Pine oil: Related to turpentine, pine oil is used as a disinfectant and deodorizer. Toxic effects: Pine oil irritates the skin and mucous membranes; large doses can cause central nervous system depression, and irritate the gastrointestinal and urinary tracts. First aid: Encourage vomiting and give a solution of one heaping spoonful of epsom salts in a cup of water. Soothing drinks like milk or egg white can be given. • Sodium hyperchlorite: More commonly known as bleach, it cleans and kills bacteria through an oxidation process. When mixed with ammonia, bleach produces toxic chlora-mine fumes. Toxic effects: Ingestion causes corrosion of mucous membranes, perforation of the esophagus and stomach, swelling in the throat. Inhalation can cause severe bronchial irritation and fluid in the lungs. First aid: If ingested, give a solution of baking soda and water. Take the patient to a doctor.

7. Shrubs
Caution is urged when purchasing shrubs at a nursery to be sure that you find out the final size of the specimen, its requirements for soil composition, pH value and drainage, location in sun or shade, and special fertilizing or other loving care needed.
