Never place a television set in an unstable location. A television set may fall, causing serious
personal injury or death. Many injuries, particularly to children, can be avoided by taking simple
precautions such as:
- Using cabinets or stands recommended by the manufacturer of the television set.
- Only using furniture that can safety support the television set.
- Ensuring the television set is not overhanging the edge of the supporting furniture.
- Not placing the television set on tall furniture (for example, cupboards or
bookcases) without anchoring both the furniture and the television set to a suitable support.
- Not placing the television set on cloth or other materials that may be located
between the television set and supporting furniture.
- Educating children about the dangers of climbing on furniture to reach the television set or its
controls
If your existing television set is being retained and relocated, the same considerations as above
should be applied.
