1. Be sun smart in the garden
Ultraviolet radiation from the sun can start to burn unprotected skin within minutes.
When the UV level is three or above: Wear a long-sleeved shirt, long trousers and a broad-brimmed hat. Moreover, apply broad-spectrum SPF 30+ sunscreen to unprotected skin 20 minutes before going outside, and reapply regularly. Avoid gardening during the hottest part of the day; the best time for gardening is either early morning or late in the afternoon.
2. Lawnmower safety
Common lawnmower injuries include open wounds and bone fractures involving the hands and feet. Eye injuries can also be caused by the mower blades flicking up debris such as sticks and stones.
Safety suggestions include:
Wear enclosed shoes when mowing the lawn, preferably safety boots with steel toecaps.
Wear appropriate eye protection, such as safety goggles.
Wear long trousers, preferably made from a heavy fabric such as denim, to protect your legs against flying debris.
Ride-on mowers can tip. Drive at slow speeds, especially when turning.
Take extra care when pulling the mower towards you or mowing on slopes, to avoid foot injuries.
Lawnmowers can also cause burns. Be careful not to touch hot equipment parts.
3. Don’t overdo it in the garden
Gardening can cause back pain and overuse injuries.
Safety suggestions include:
Avoid long gardening sessions.
Warm up before gardening with slow, sustained stretches and remember to do basic back stretches during your gardening.
Rotate your tasks to avoid repetitive movements. For example, after 15 minutes of raking, swap to pruning for a while.
Rest frequently and relax in the shade with a drink of water.
Avoid uncomfortable positions.
Bend at the knees and don’t strain when lifting heavy objects. If the object is too heavy for you, seek help.
