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
Metal braided hoses are much more resistant to bursting.

Plugged dryer vents are a fire hazard
Plugged vents and hoses are a fire hazard.

This hot water heater is leaking combustion gasses into the home This hot water heater has exhaust rollout. Improper flue design or inadequate air supply can cause combustion gasses to vent into the home. If your heater has these stains please have it checked out.

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!
Read more about back-drafting hazards here.

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!

Outdoor electrical safety tips for holiday lighting

Holiday lighting is a wonderful tradition, and these tips will help to keep you and your family safe.

Use care not to overload your circuits. Do not run too many strings together, the amount of lights on string that can safely be connected differs for each type of light. Read and follow the manufacturer's recommendations. Carefully inspect each string for frayed insulation, loose connections or broken bulbs. Never plug in a string that has bulbs broken open, as the interior filament is a electrocution hazard. Only use lights outdoors that are approved for outdoor use.

Use timers to control your lighting to save more energy. This chart dramatically contrasts the old style bulbs with modern LCD technology lighting using as little as 1.15% of the energy of the old style lighting.

Another consideration is heat. Never install old style bulbs on a real tree. Think of string of 100, 10 watt lights, that is 1000 watts light and heat. You would never put a 1000 watt heater on a tree for obvious reasons, and these strings are nearly the equivalent of doing just that.

Be careful when hanging lights. Loose wiring is more easily damaged by movement from trees and wind. Never use standard staples, as they can cut into insulation and cause a short or shock hazard. Best to use insulated clips to hang lighting.

GFCI protected outlets are recommended for all outdoor electrical use. They dramatically reduce the risk of electrical shocks and electrocutions.

Use only UL approved exterior grade power cords outside with proper ground (3 prong connector). Never run cords through doorways, windows where they could get damaged or be a trip hazard. Keep all plugs and connectors off the ground, away from puddles and snow.

If you blow fuses or trip breakers, reduce the load on that circuit. Never change the amperage if a blown fuse, if a 15 amp fuse blows, reduce the load on that circuit and replace with the exact same type 15 amp fuse. The wiring in the home is designed to only carry the current of the fuse. That blown fuse likely prevented the wiring from overheating and possible fire.

If you see flickering lights, sparks, warm switches, plugs, or outlets, or dimming lights, there is a potential dangerous problem that could cause an electrical fire.

As always use extreme care on ladders, make sure they have a good footing and are steady. Never touch your exterior power drop! Any contact with a poorly insulated drop will kill you, an aluminum ladder is an excellent electrical conductor.

Housing Safety for the Elderly

Housing Safety for the Elderly
As we age our senses are not as sharp and the loss of the sense of vision, smell, hearing and touch can result in injury. With the frequent bone loss of older individuals, the risks from falling are magnified. A simple fall can result in a serious incapacitation injury that can lead to loss of independence. These tips while intended for elderly safety apply to all people, especially children and pets.

Security
Check doors and locks for easy operation and security. All doors should have secure deadbolts that do not require a key from the inside. We recommend 180 degree peepholes at the appropriate height and good porch lighting. You might consider alarm systems for peace of mind.


Phones
Put emergency contact information, doctors, hospitals, pharmacy, etc next to the phone. Make sure the address is listed along with family contact information. Remember that most cordless phones will not work during a power outage, so always have at least one non powered corded phone.

Safety Equipment
Test all smoke alarms, and if they have them, change the batteries on a regular cycle like daylight savings time change. If the residence has any combustion appliances (furnace, hot water, fireplace, stove, ect.) or and attached garage we also recommend carbon monoxide detectors. We recommend that you locate any safety equipment your building may have, like fire extinguishers, fire escapes and central alarms. Consider installing extinguishers inside the home and near any barbeques and garages.
Read more Fire Safety Tips from the Consumer Product Safety Commission.

Kitchens
Check the lighting assuring that it is adequate to clearly see cooking and working areas. Check location of lighting switches, they should be easily assessible near the doorways. Hot water can severely scald, so assure the water temperature is set no higher then 120 degrees. Single conrtol faucets are less likely to cause burns. The flooring should be easily cleaned, not slippery, and any rugs or pads should have non skid backing to help prevent falls. Controls for the range and oven should be in front or beside, not in back where you would have to reach over a burner. All kitchens should have GFCI protected outlets within 6 feet of water. These should be tested regularly to assure they are working. A circuit properly protected by a GFCI can prevent 2/3 of all electrocutions.

Halls and Rooms
Inspect all stairs and halls for trip hazards at carpet/flooring edges, thresholds, cords, etc. Look around for sharp edges on furniture, trim, shelving and heaters that could be hazardous in case of a fall. Check for good lighting and switch locations.

Stairs
Since so many injuries occur on stairs, we have dedicated a web page to stair safety. You will find more complete safety info there. Some of the tips include..
1) Continuous handrails:
Consider installing secure hand raills on both sides of steps. They should be at the correct height, easy to grasp and solid construction.
2) Vertical balustrades:
These are to assure there is no opening greater then 4"
3) Even Treads, to prevent trips
4) Good Lighting, with light switches at top and bottom of stairs.
5) Closed risers, these are much less likely to cause a trip.
6) Clear approaches
