Laundry Safety

We use laundry equipment everyday with out a lot of thought to the potential hazards they may pose. According the the Consumer Product Safety Commission washers and dryers are responsible for more then $230,000,000 worth of property damage a year in the US alone. Most of the common problems at the root of these statistics are easy to address.

Power Cords

We found this dryer power cord on an inspection, notice it does not have a proper strain relief connector.

All dryers should have proper strain reliefs for the power cords

As with all power cords be careful when you use the plugs, but ESPECIALLY with large 240 volt connections. The plugs are large and require a bit of effort to insert, making it necessary to wrap your hand around the plug and it is easy to accidentally touch the conductors when inserting or removing them. This same advice applies to all large sockets like electric ranges, RV plugs, large tools etc.

Metal braided hoses are much more burst resistiant then plain rubber hoses

Dryers use a lot of power, and usually do not come with their power cords installed when you buy them. When hooking up a power cord, follow the manufacturers instructions, and be sure to have the proper strain relief fitting. Since dryers vibrate and can have sharp edges to the sheet metal enclosures, cords can short out, causing a potential fire or electrocution hazard.

Washing machine hoses
These hoses are under pressure all the time and can burst causing extensive water damage to the home. Since washers will jiggle when they operate the hoses can rub against the wall behind them. We always recommend the metal braided hoses for washers since they are much more burst resistant and less likely to be damaged by the movement of the appliance. Leave at least 4 inches of space behind the washer to prevent hoses from kinking or chafing and inspect them regularly. If you see any bulges, rust or any other damage, replace them right away.

Dryer vents and lint build up

It is recommended that you check and clean the dryer venting regularly. Use flexible metal pipe, not the foil or vinyl accordion type hoses, they are more likely to catch lint and have an increased risk of fire.
Read an article on cleaning dryer vents here.

Smoke detectors are important in laundry areas, since fires associated with dryers cause more then $80 million of damage a year. Be sure that dryers are properly vented outside and not leaking inside the home, attic or crawlspace as this moisture is a conducive condition for structural pests. If there is significant lint buildup inside, your dryer vent is likely leaking.

Fresh air/back drafting
When dryers run they exhaust a lot of air outside the home. This can produce a negative air pressure condition leading to a possible back-drafting of combustion gasses from furnaces, hot water heaters etc. This problem is especially true in modern energy efficient homes or confined spaces such as a closet. All homes with combustion appliances must have carbon monoxide detectors!

GFCIs can prevent 2/3rds of all serious electric shocks and electrocutionsGFCIs
When properly installed, GFCIs prevent two thirds of all serious electric shocks a year. All outlets with in 6 feet of water, (laundry, kitchens and bathrooms) in garages or outside should have GFCIs. They are cheap and easy to install and might save your life.
Read how install them here.

Explosion hazards
Both washers and dryers have electric motors and other components that can produce sparks capable of igniting flammable vapors or gasses. Laundry equipment are sometimes in garages where there may be gasoline, paint, solvents, propane etc. Always store these chemicals in their original, properly labeled air tight containers. If there is a spill, DO NOT use any electrical appliance or garage door openers until it is cleaned up and all vapors have dissipated.

Keep flamables away from all appliances, especially gasoline!

Private Well Maintaince

Private wells provide drinking water for many people in western Washington, but most wells are not maintained properly. It is recommended that they have and annual check up for bacteria or anytime there is a change in odor, appearance or taste. Water tests may include coliform bacteria, nitrates, iron, manganese, water hardness, sulfides and others. If there is a significant change in these levels, there may be an indication of changes in the water table. The well's flow should be checked to determine output, pump checks including amperage, voltage and proper grounding. Have the pressure tank and pressure switch checked too. The company performing these checks should provide you a detailed report on all conditions, recommendations and lab results. Be sure to keep this information in a safe place to provide ongoing information to monitor for any changes.

Don't put hoses onto mixing containers for pesticides, fertilizers or other chemicals as this can allow these chemicals to be drawn into your water supply. Use care when adding mulch or other ground covers always maintain 12 inches of clearance from the ground to the well head. Be careful with mowers and other yard equipment to prevent damaging your casing or cap. Keep snow, leaves or other debris from the area around the well. All these can lead to contamination.

Other tips for well owners include keeping hazardous materials away from your well such as gasoline, paints, thinners, and pesticides. Make sure your well is not located too close to buildings or septic systems. Keep your septic properly maintained by having your tank pumped regularly and drain field checked.

Well Shocking (from the state of Maine Dept of Health)
"Frequently, bacteria can be introduced during the well drilling process, installation of the pump system, subsequent servicing of the well pump, pipe repairs, storage tank replacement, or an inadequate well cap installation allowing vermin and insects access to the well casing. Any cause or causes for contamination should be fully investigated prior to shock chlorination, since contamination will likely reoccur if the cause is not addressed." Read the entire article here.
