| Evacuated glassware |
When glassware under vacuum breaks, the implosion may
spray glass pieces around. So, any glass Dewar vessels or evacuated
flasks must be covered with strong sticky tape, plastic netting or
be metal shrouded.
Glassware under pressure is even more dangerous and should
only be used with total containment. |
| Broken glass and empty bottles |
Broken glass or used disposable pipettes and other items, may be
put only in waste bins labelled Sharps - this is for the safety
of cleaning staff who empty waste bins.
Before they leave your laboratory it is vital that all bottles
for disposal are treated in the following way:-
- Any sodium residues in bottles must be carefully destroyed
and the bottles washed with water;
- All bottles should be completely emptied of solvents and chemicals
then washed and dried to the extent that there is no residual
odour from them;
- Cleaned bottles can be put unstoppered
into the waste bins.
