Here are some additional safety tips:
Most labs do not allow eating or drinking in the lab and it is not safe.
If using radioisotopes, please use double gloves and put on your radiation badge to monitor your exposure.
Use properly fitting lab-coats, if sleeves are too long then roll them.
If using formaldehyde or related chemical, please use mask to protect yourself from inhaling vapor.
Disposable glass pipettes should be discarded properly in their special disposal and not the regular trash. Same is true for radioactive wasted including gloves that might be contaminated.
