1-Do not use laboratory containers or refrigerators to store drinks or
food, or put chemicals in food containers
(bottles of water, etc.).
2-Work whenever possible in the fume cupboard, especially
if you handle volatile, toxic powdered products, when you do
experiments that generate fumes or gases, etc.
3-Use personal protective equipment (gloves, glasses,
masks, etc.) suitable for each job and risk.
Hope this can help you
