Household Health · Chapter 7
Household safety
Most household injuries are predictable. A smoke alarm with a dead battery. A loose rug at the top of the stairs. A bathroom with no grab bars. A toddler and a bookshelf that is not anchored to the wall. The hazards do not hide. They sit in plain sight until familiarity makes them invisible. This chapter is about seeing them again.
Start your safety walkPlanning guidance, not medical advice
This page covers household injury prevention. It does not provide medical advice. If someone is injured, follow the care routing in Chapter 1. Poison-specific prevention and response are covered in the companion chapter on poisoning prevention.
The principle
Find predictable hazards before they injure someone
Household injuries follow patterns. Burns happen in kitchens and bathrooms. Falls happen on stairs, in bathtubs, and on loose rugs. CO poisoning happens in homes with fuel-burning appliances and inadequate ventilation. Furniture tip-overs happen where heavy furniture is not anchored and small children are present. Drowning happens wherever standing water is accessible to a child.
The patterns are well documented. The prevention measures are straightforward. The gap is not knowledge. It is attention. A family moves in and never installs grab bars because no one in the house needs them yet. A smoke alarm battery dies and the chirping gets ignored for a week, then a month. A toddler learns to climb and the bookshelf that was fine for a crawler becomes a tip-over risk overnight.
This chapter does not try to cover every possible hazard. It covers the categories that injure the most people in the most homes, using the guidance of the agencies that track them: CPSC for product and home safety, and CDC for fall prevention. The twice-a-year safety walk at the end ties everything together into a routine that catches what has changed since you last looked.
Detection
Smoke alarms: where, how many, how often
CPSC recommends smoke alarms on every level of the home, inside each bedroom, and outside each sleeping area. That means a two-story home with three bedrooms needs at minimum five alarms: one in each of the three bedrooms, one in the hallway outside the bedrooms, and one on the main floor.
Smoke alarm maintenance
Test monthly by pressing the test button. If the alarm does not sound, replace the batteries. If it still does not sound after fresh batteries, replace the unit.
Replace batteries at least once a year, or immediately when the alarm chirps. Some sealed units have 10-year batteries that cannot be replaced; replace the entire unit when the battery dies.
Replace the unit every 10 years or according to the manufacturer's instructions. The manufacture date is printed on the unit. If there is no date and you do not know when it was installed, replace it.
Never disable an alarm because of cooking smoke or nuisance alerts. Move it farther from the kitchen, use the hush button if it has one, or replace it with a photoelectric model that is less prone to cooking false alarms. A disabled alarm protects no one.
Interconnected alarms
If one alarm sounds, ideally all alarms in the house should sound. Interconnected alarms (wired or wireless) ensure that a fire in the basement wakes someone sleeping on the second floor. If your home has standalone alarms, consider upgrading to interconnected units, especially in larger homes or homes with bedrooms on multiple floors.
Renters
If you rent, your landlord is generally responsible for providing working smoke alarms. If alarms are missing, have dead batteries, or are not working, notify your landlord in writing and document the request. If the landlord does not respond, contact your local fire department or housing authority. In the meantime, battery-powered smoke alarms are inexpensive and can be installed without tools or permanent mounting.

Carbon monoxide
CO alarms: the gas you cannot see or smell
Carbon monoxide is produced by anything that burns fuel: furnaces, water heaters, gas stoves, fireplaces, generators, grills, and vehicles running in attached garages. CO is colorless and odorless. Without an alarm, you cannot detect it until symptoms appear, and the early symptoms (headache, dizziness, nausea) are easily mistaken for something else.
CPSC recommends CO alarms on every level of the home and outside sleeping areas, installed according to the manufacturer's instructions. Replace CO alarms on the manufacturer's replacement schedule, which is typically five to seven years depending on the model. The replacement date matters: CO sensor elements degrade over time and lose sensitivity, unlike smoke alarms where the main failure mode is a dead battery.
If the CO alarm sounds
Get everyone outside to fresh air immediately. Call 911. Do not go back inside to find the source. Do not open windows to "air it out" and re-enter. Do not re-enter the home until emergency responders have tested the air and confirmed it is safe. CO exposure can be life-threatening, and the alarm is telling you the concentration has reached a dangerous level.
Combination units
Combination smoke and CO alarms are available and can simplify installation. They follow the placement rules for both types: every level, every bedroom, outside sleeping areas. Check the replacement schedule for both the smoke and CO sensors, which may differ even in a combination unit.
Homes without fuel-burning appliances
Even all-electric homes should have CO alarms. An attached garage with a running vehicle, a neighbor's generator during a power outage, or a guest who brings a fuel-burning appliance indoors during an emergency can introduce CO into any home. The alarm is inexpensive insurance against a scenario that kills hundreds of people every year.

Older adults
Fall prevention: not inevitable, not just housekeeping
Falls are the leading cause of injury among older adults, and CDC states clearly that falls can be prevented. The STEADI (Stopping Elderly Accidents, Deaths & Injuries) initiative provides resources for both older adults and their caregivers. Fall prevention is not just picking up throw rugs. It is a combination of home modifications, physical conditioning, medication review, and medical evaluation.
Home modifications
Remove trip hazards: loose rugs (or secure them with non-slip backing), electrical cords across walkways, clutter on stairs, boxes and objects on the floor in hallways
Improve lighting: bright, even lighting in hallways, stairs, bathrooms, and any path walked at night. Night lights in the bedroom, bathroom, and hallway. Light switches accessible at both ends of stairways and hallways.
Install railings: sturdy handrails on both sides of all stairways, securely anchored into the wall studs. A railing that pulls away from the wall is worse than no railing because it creates a false sense of security.
Bathroom modifications: grab bars near the toilet and in the shower or tub (anchored into studs, not attached with suction cups), a non-slip mat in the tub or shower, a shower seat or bench if balance is a concern, a raised toilet seat if needed.
Frequently used items at accessible height: move items used daily to counter height or between waist and shoulder height. Reaching overhead or bending to floor level increases fall risk.
Beyond the home
Home modifications are the visible part. The less visible part is equally important: discussing fall risk with a health professional. Certain medications increase fall risk (sedatives, blood pressure medications that cause dizziness, some pain medications). Vision changes affect balance. Inner ear problems cause vertigo. Muscle weakness and poor balance can be improved with specific exercises.
CDC recommends that older adults talk to their doctor about fall risk, have their medications reviewed for fall-related side effects, have their eyes checked annually, and do exercises that improve strength and balance. A physical therapist can assess gait and balance and design a targeted exercise program.
Repeated falls are not normal aging
If someone in the household is falling repeatedly, that is not just a housekeeping problem that needs more grab bars. Repeated falls warrant a medical evaluation. The falls may signal an underlying condition (neurological, cardiovascular, medication-related, or vision-related) that is treatable. Do not normalize repeated falls as "just getting older."

Children
Childproofing that grows with the child
CPSC provides detailed guidance on making a home safer for children. The core principle is that childproofing is not a one-time project. It is an ongoing adjustment that changes as the child's abilities change. A four-month-old cannot open a cabinet. A fourteen-month-old can. A two-year-old cannot climb a bookshelf. A three-year-old will try. Every new motor skill the child develops is a new set of hazards to address.
CPSC childproofing categories
Gates and barriers
Hardware-mounted gates at the top and bottom of stairs. Pressure-mounted gates in doorways where a fall is not a risk. Gates should be tall enough that the child cannot climb over and should not have horizontal bars that serve as a ladder.
Furniture anchoring
TVs, bookshelves, dressers, and any heavy furniture that a child could pull over must be anchored to the wall with anti-tip straps or brackets. Furniture tip-overs kill children every year, and CPSC has made this a priority safety message. Wall anchoring kits are inexpensive and take minutes to install.
Electrical safety
Outlet covers or tamper-resistant receptacles on all accessible outlets. Cord management to keep lamp and appliance cords out of reach. Extension cords out of reach and not used as permanent wiring.
Water safety
Water temperature set to 120 degrees Fahrenheit or below at the water heater to prevent scalding. Never leave a child unattended near any water: bathtubs, buckets, wading pools, toilets. Drowning can happen in as little as one inch of water and in less time than it takes to answer a phone.
Window and blind safety
Window guards or window stops on upper-floor windows to prevent falls. Windows should open no more than four inches, or have guards that an adult can open in an emergency. Blind cords are a strangulation hazard; use cordless blinds or retrofit existing blinds with cord-shortening devices.
Lock-away storage
Medicines, cleaning products, and any toxic substances locked or stored out of reach. Cabinet locks on lower cabinets that contain anything a child should not access. This overlaps with the poison prevention chapter, which covers storage and response in depth.
Revisit childproofing every six months
Every six months, walk the house from the child's perspective. Get down to their height. Look at what they can now reach, climb, open, pull, or put in their mouth that they could not reach six months ago. The hazards at twelve months are different from the hazards at six months, and different again at eighteen months, twenty-four months, and thirty-six months. Childproofing is a moving target until the child is old enough to understand the hazards, and even then, supervision matters more than hardware.

Individual needs
Safety is person-specific
A generic "safe home" checklist misses the most important variable: who lives there. The safety profile of a home changes with every person in it, and it changes when their condition changes. A home that is perfectly safe for two healthy adults becomes a different environment when a baby arrives, when a grandparent moves in, when someone starts using a walker, or when someone begins using home oxygen.
Conditions that change the safety picture
Mobility limitations: Clear pathways wide enough for a walker or wheelchair. Remove thresholds and area rugs that catch wheels or cane tips. Ramps or stair modifications if the home has level changes. Furniture arranged to allow passage, not just walking room.
Low vision: High-contrast tape on stair edges. Consistent lighting without dark patches. Label or color-code items that need to be distinguished (medications, controls, switches). Remove glass coffee tables and low furniture that is hard to see.
Cognitive changes: Stove knob covers or auto-shutoff devices. Locks on exterior doors that can be opened from inside in an emergency but prevent wandering. Nighttime path lighting. Remove or lock away items that could cause harm if used incorrectly.
Home oxygen: No open flames, no smoking, no candles in any room where oxygen is used or stored. Oxygen concentrators and tanks need adequate ventilation. Keep oil-based products away from oxygen equipment. Post a sign visible from the front door so emergency responders know oxygen is in use.
Medical devices that require power: Know which devices are battery-backed, how long the backup lasts, and what the plan is if power fails. Devices include CPAP machines, home ventilators, electric wheelchairs, infusion pumps, and powered hospital beds. If someone in the home depends on powered medical equipment, register with your utility company as a medical-priority account.
When a household member's condition changes, walk the house again with their new reality in mind. The safety assessment that was accurate six months ago may no longer be correct.
The routine
The twice-a-year safety walk
Pair this with the spring and fall time changes, or with the twice-a-year medicine and kit audit from earlier chapters. Set aside thirty minutes. Walk every room in the house with a checklist. The walk catches what daily familiarity makes invisible.
| Area | Check |
|---|---|
| Smoke alarms | Test every unit. Replace dead batteries. Replace any unit over 10 years old or with no visible manufacture date. Confirm coverage: every level, every bedroom, outside sleeping areas. |
| CO alarms | Test every unit. Check manufacture date against replacement schedule. Confirm coverage: every level, outside sleeping areas. |
| Stairs and hallways | Railings secure. Lighting adequate. No clutter, cords, or loose items on steps. Non-slip treads if surfaces are slippery. |
| Bathrooms | Grab bars secure (if installed). Non-slip mats in tub/shower. Water temperature at or below 120 degrees F. GFCI outlets functioning (press test/reset buttons). |
| Kitchen | Fire extinguisher present, charged, and accessible. Pot handles turned inward on stovetop. No combustibles near heat sources. Knife storage secured if children present. |
| Living areas | Furniture anchored to walls where tip-over risk exists. Cords managed. Area rugs secured or removed. Adequate lighting, especially path lighting at night. |
| Bedrooms | Smoke alarm in each room tested. Path from bed to door clear. Night lighting functional. Space heaters (if used) at least three feet from combustibles and turned off when unattended or sleeping. |
| Garage and exterior | No vehicle running in enclosed garage. Chemicals and fuels stored away from heat and living areas. Exterior lighting functional. Walkways and steps in good repair, no ice or debris. |
| Person-specific | Any changes in household members' abilities since last walk? New mobility, vision, or cognitive needs? Child development milestones that change the hazard picture? New medical equipment? |
Fix what you find during the walk, not after. A dead battery is a two-minute fix. A loose railing is a thirty-minute fix. An unanchored bookshelf takes ten minutes and a kit from the hardware store. The walk is only useful if the findings turn into actions before daily life makes them invisible again.
Escape planning
Two ways out of every room
Every person in the household should know two ways out of every room they sleep in or spend significant time in. In most rooms, this is the door and a window. In some rooms, both exits may be doors. The point is that if one exit is blocked by fire or smoke, there is another route.
Walk the exits with your household. Open the windows. Make sure they open easily, that screens can be removed, and that any security bars have a quick-release mechanism that can be operated from inside without a key. For upper floors, know whether a window leads to a roof that can be safely accessed and whether a fire escape ladder is needed.
The meeting point
Choose a meeting point outside the home where everyone goes after exiting. It should be far enough from the building to be safe (across the street, at the mailbox, at the neighbor's tree) and specific enough that there is no confusion. Practice getting there. Time it. Do it at night with the lights off, because that is when most fatal fires occur.
Practice with children
Children need to practice, not just hear the plan. Walk them through the exits. Show them how to test a door for heat before opening it (use the back of the hand on the door and handle). Show them how to stay low if there is smoke. Make sure they know the meeting point and understand that they should never go back inside for a toy, a pet, or anything else. Practice at least twice a year, ideally aligned with the safety walk.
