, • D2 - Analyse why good laboratory design is important for efficiency, effectiveness and safety.
• To have an efficiently running laboratory a good laboratory design is necessary. A laboratory that is used regularly lead
in the cost as everything stays in working order. Therefore, nothing needs repairing and new chemicals etc are needed
everything is still useable.

goggles should be worn in the laboratory. Eyewash stations can help to avoid blindness or burns depending on the con

• Having a clean well-organised laboratory contributes to its smooth running. It helps to make sure that all activities are
with care and everything has its own order and place so that it can be found easily and so that it can be in the right pl
