Child Safety Features We all know some liquids can be fatal to young children. They can breathe chemicals in if the wrong spray nozzle is used or some liquids can actually burn the skin. Child safety is very important when choosing your trigger pump. Here are our 4 top child safety tips: #1. If the chemicals are toxic to the lungs consider a foaming option. #2. Most trigger sprayers come complete with a twist lock on the end of the nozzle. This is a perfect solution for young children. #3. Some trigger sprays come with a snap click screw cap. This design is very difficult to remove. #4. Trigger sprayers can also come with an on/off clip that slides left to right for a working and non-working mode.
