Household items and electronics

Technology is a part of our everyday lives. It is important to know that our household items and electronics are safe.

Blue light and light emitting diodes (LEDs)

Blue light plays an important part in keeping our body clock in time with the day and night cycle. Exposure to too much blue light in the evening or at night could disrupt the body clock, causing poor sleep and possible other effects.
Cellphones

Cellphones connect to a network using radiofrequency radiation. This is different to the radiation from x-ray equipment and radioactive sources.
Child-resistant packaging

Child-resistant packaging can help prevent poisonings but they are not child proof. All medicines and poisons should be locked away.
Laser pointers

Powerful, low-cost laser pointers are becoming more common. A laser pointer might look like a toy, but it can be very harmful.
Microwave ovens

The microwaves used in a microwave oven are a form of radiation, like light or radio waves. The energy in the microwaves cooks the food.
Poisons around the home

Many things we have in and around our homes are poisonous, and very appealing to children.
Smoke alarms

You should always have a working smoke alarm in your home. It could save your life.
WiFi networks and computer equipment

WiFi (or wireless networking) is a way to connect a computer or other device to a network. It uses low-power radio signals instead of cables.
Unflued gas heaters

Heating is important during winter, especially for those in colder climates. But unflued gas heaters release gases that can harm you.
