PC1 laboratory rules and eating in classrooms

PC1 laboratory rules and eating in classrooms: Are all school laboratories classified as PC1 laboratories and if so are students permitted to eat in classrooms? For example, when a teacher wants to demonstrate digestion practicals, can they eat shop bought items such as biscuits, lollies to demonstrate why mastication is important or if they've used food as a model e.g. snack tectonics, can the students eat them? When practicals revolve around the making of cheese or yogurt using lab equipment can the created items be consumed? Many thanks for your reply.

Animal skeleton

Animal skeleton: One of our teachers can get a sheep skeleton from someone. The sheep died in a field and the bones are now devoid of any flesh. The teacher wants to know if there is a way in which the skeleton can be cleaned/sterilised so it can be used in the classroom to show the structure of the long bones and the spine etc. I know that we are not allowed to use anything not sourced from a reputable supplier (because of possible disease, fungus and pathogens it may be carrying) but the teacher would like to know if there is something that can be done so she can use it.

Chemical storage

Chemical storage: I am after some information regarding safe storage of chemicals in schools. We have one small prep room with all of the chemical cabinets in said prep room. I was under the impression stock chemicals should be stored in a separate room with a locked door?

I have an OH&S meeting next week and was hoping to have some information to back up my claim that we need a separate chemical store. Any chance you could help or direct me to useful info?

Thanks for your time.

Use of lead in ACT schools

Use of lead in ACT schools: From reading answers to another question, it's my understanding that lead is banned in some Australian jurisdictions, and approved or restricted in others.

Can anyone tell me if lead (solid, lead shot, salts) is allowed to be used in Years 7 to 10 in ACT class rooms? Or where exactly I go to find this out?

HCl + NH4OH Reaction

HCl + NH4OH Reaction: Hi, could you please advise me about a demo of HCl and NH4OH fumes mixing? Is it safe enough to put 30 ml (or less?) of each into separate petri dishes in the fume hood? Can the fume hood be turned off for 10 seconds for better visibility of the NH4Cl and then turned back on again?

Mixing of alcohols

Mixing of alcohols: an IB student would like to investigate the effect in heat energy of mixing methanol and ethanol or ethanol or propanol or ethanol and butanol, is this safe? I read SDS and it doesnt provide any information regarding this query. Hope you can help. Many thanks
