#1 Science Forum For Lab Technicians

We have safety glasses have to be worn during all practicals, or they sit down. Ever seen what a broken scalpel can do, not pretty.

Ours wear gloves with all Chemicals no matter what strength. Blanket rule, then no room for teachers thinking it doesn't matter at certain strengths.

I have one teacher who just loves to use Butyric acid, I was away the day it was done last year. They evacuated the Science block, I could still smell it the next day. You can't get the smell out of your nose.

Just after a quick answer on the time for ordering pracs., just on a normal week. 24 hours, 48 hours or longer notice?

Going into a meeting looking for as much information as I can.

Thanks

Hi Brains trust!!

We have been told we have to have a corrosive cabinet, we have a flammable liquids cabinet inside our chemical room which is well ventilated 24/7. It's been suggested that a small 50L corrosive cabinet could be placed on top of flammables cabinet. Can anyone see a problem with ...

Years ago (pre 2005) we had a box of bones complete with skull, clearly human going on the teeth alone. Marked as prepared in India. The Nun at the time asked me to contact the funeral directors $$$$$ she suggest they could be put in with someone else. :crazy:

They had been in the cupboard for ...

A bit of brain fog at the moment, are the bio kids allowed to grow mould then transfer to Nutrient Agar Plates?

I'm so lucky my prep. room is central to the labs, all glassware stays with me and goes out on the trolleys as requested for each prac., teachers get them to rinse free of chemicals before returning.

Hi Brains trust,

New solution Date (8/24) Diluted from stock solution 8/24 D Decanted from Diluted stock solution 8/24 DD

Please let me know ...

I wouldn't be using HCl kids aren't allowed to use concentrated even if they are going to dilute it. 10M they are, why can't the use 1.0M 50mls it would still work and not be as dangerous. We also have the plastic burettes so I guess that would make it easier.

For those who refuse to make up bromine water from scratch. (after a bad accident) Georgia Deretic who co-wrote Foschem Senior Chemistry gave me a substitute that works just as well and less dangerous.

50 gms Potassium Bromide
