This topic covers how domestic technology, utility services, and daily safety routines work together to run an efficient home. Junior Cycle exam questions regularly test appliance choices, child and fire safety, emergency responses, and everyday resource conservation.
Domestic Technology and Choosing Appliances
Technology applies scientific ideas to make household chores quicker, cleaner, and less tiring. We divide domestic electrical appliances into three main groups:
- Large appliances: bulky items like cookers, refrigerators, and washing machines.
- Small appliances with a motor: devices with moving parts, such as food mixers and blenders.
- Small appliances with a heating element: tools that heat up, like kettles, toasters, and irons.
Impact on the home
Smart tech lets you control heating or security from a phone, which cuts bills and saves time. Digital apps make meal planning and family budgeting much simpler. On the downside, modern devices are expensive to buy, require costly repairs, and create electronic waste when thrown out.
Choosing an appliance
When buying, look beyond the purchase price to check running costs, size, and the energy rating label (rated A to G). Always check for safety marks: the CE mark confirms the product meets EU safety laws, while the Irish Standard Mark (NSAI) shows it meets Irish quality standards.
Home Safety, Fire, and Hygiene
Most domestic accidents happen to young children and older people, but simple precautions prevent serious injury.
Child safety measures
- Burns and scalds: turn saucepan handles inwards on the hob and fit a nursery guard around open fires.
- Falls: keep stairs brightly lit, fit stair gates for toddlers, and wipe floor spills immediately.
- Poisoning: keep medicines and cleaning products in high presses with child-proof safety catches.
- Choking: keep coins, buttons, and loose blind cords well out of reach.
Cleaning agents and fire safety
Detergents remove grease, disinfectants kill germs, and abrasives scour heavy stains. Always keep chemicals in their original labelled containers and never mix them. Fit smoke alarms on every floor and install a carbon monoxide alarm in rooms with fuel-burning appliances. If a chip pan catches fire, smother it with a fire blanket; never pour water on burning oil.
Household Utilities and Emergency Procedures
Homes depend on electricity, gas, and mains water. Knowing how these services work helps you act fast in an emergency.
Water supply treatments
Before drinking water reaches your tap, Uisce Éireann (formerly Irish Water) carries out key treatments:
- Screening: water passes through wire mesh screens to remove large debris like twigs and leaves.
- Chlorination: chlorine is added to destroy harmful bacteria and make the water safe to drink.
- Fluoridation: fluoride is added to strengthen teeth and protect against tooth decay.
Handling emergencies
- Gas leak: open windows and doors, extinguish naked flames, and turn off the gas at the meter. Do not touch any electrical switch or doorbell, because an internal spark can ignite the gas. Leave the house and call the gas emergency service (the gas company) from outside.
- Burst pipe: turn off the water at the mains stopcock immediately. Turn off the heating and immersion, open cold taps to drain the system, and call a plumber.
Sustainable Living and Waste Management
Everyday habits reduce our carbon footprint and save money on household utility bills.
Energy and water efficiency
Turn the heating thermostat down by 1°C, fit LED bulbs, and insulate the attic. Every home for sale or rent must have a Building Energy Rating (BER) certificate, which grades energy efficiency from A (most efficient) down to G. Conserve water by taking short showers instead of baths, turning off the tap while brushing teeth, and only running washing machines with full loads.
Waste management
The EU waste hierarchy sets out the best ways to handle rubbish: prevention is best, followed by minimisation, reuse, recycling, energy recovery, and landfill disposal as the last resort. Use your three household bins correctly: green for clean, dry recyclables; brown for organic food waste; and black for general rubbish. Under the WEEE scheme, you can recycle any broken electrical item with a plug or battery for free.
Key terms
- CE Mark
- A European safety symbol proving that a product complies with European Union safety, health, and environmental standards.
- Building Energy Rating (BER)
- A certificate that rates the energy efficiency of a home on an A-to-G scale, where A is the most efficient.
- Mains Stopcock
- The main shut-off tap that turns off the incoming mains water supply to a house.
- Chlorination
- The addition of chlorine to mains drinking water to kill harmful bacteria and make it safe.
- Fluoridation
- The addition of fluoride to public water supplies to strengthen tooth enamel and prevent decay.
- Waste Hierarchy
- An EU guide that ranks waste options from most sustainable (prevention) to least sustainable (landfill disposal).
- WEEE
- Waste Electrical and Electronic Equipment; an EU initiative allowing free recycling of goods with plugs or batteries.
