There are a number of safety considerations with the dispensing of liquids using needles and syringes. When used effectively, needles and syringes offer a convenient and safe way to dispense reagents, and give access to air sensitive chemistry that would not be possible without their use. This page covers some of the safety aspects to bear in mind whilst carrying out liquid dispensing.

The use of needles presents a risk of needlestick injuries. The sharp bevelled point of a needle is easily able to pierce gloves and skin. When chemicals are being handled, these could potentially enter the body via an injection route in the event of a needlestick injury.

Following proper practise for the use of needles and syringes should minimise the likelihood of needlestick injuries. The proper operation has been carefully designed to minimise the likelihood of any needlestick injuries occurring, and it is important to follow these procedures carefully.
