  • Greetings esteemed chemists.

  • We know you're all positively brimming with excitement and enthusiasm,

  • ready to get into that laboratory and revel in some chemistry.

  • But hold your horses, first we have a few laboratory rules

  • and safety precautions to go over, because your safety is paramount.

  • First up the iconic lab coat

  • which not only makes you look like a real scientist just like the ones on TV

  • but also serves to protect your clothing and skin. Keep it buttoned up at all times.

  • But remember not wear it in clean spaces such as offices or writeup areas.

  • Next always protect your peepers with these flattering safety spectacles.

  • Never enter the lab without these spectacles on

  • and always wear them on your eyes, not on your head.

  • Remember to dress appropriately for laboratory work.

  • Short skirts and sandals leave skin exposed to possible nasty burns and other injuries.

  • Loose hair can also be hazardous while in the lab.

  • It could impede your vision, accidentally dip in to chemicals,

  • get caught in equipment or even catch fire. So keep those luscious locks tied back.

  • Always keep your mitts clean.

  • Wash your hands often both when you enter and exit the laboratory.

  • Now you're ready and properly dressed but before you begin any work in the lab

  • it is vital to carry out a risk assessment

  • in order to identify hazards and take practical steps to reduce the risks

  • of harm to yourself, others and damage to property.

  • Before using any equipment make sure it's in good working order first.

  • Broken equipment can not only adversely affect your work but also pose a huge safety hazard.

  • Respect the chemistry, check your apparatus and that includes glassware.

  • Keep an eye out for broken edges or cracks,

  • as once the glass is put under the stress of heating or a vacuum

  • you run the risk of *crack* and no one wants that to happen, do they?

  • Another potential hazard is mobile phones. Not only can they cause a distraction

  • but they also have an irritating tendency to emit loud noises at

  • inopportune times so check your laboratory's policy on mobile phones

  • before bringing yours along.

  • A tidy lab is a safer lab and that includes the walkways.

  • Boxes and trailing cables can cause serious tripping incidents.

  • Similarly, cluttered or untidy work areas are a bad idea too.

  • Keep your workspace clear and clean up spillages immediately.

  • Leaving splashes of various chemicals around is risky business

  • Any bottles you use should also be labeled

  • clearly with both the contents and your initials to prevent unnecessary confusion.

  • No matter how peckish you are never ever eat in the laboratory.

  • You never know what the surfaces or your hands could be contaminated with.

  • Certainly not something you want to ingest. This is how super villains are made you know

  • and there you have it. Follow these simple laboratory rules

  • and you'll greatly reduce the risk of hurting yourself or someone else.

Greetings esteemed chemists.
