We've covered what to wear, PPE, safety equipment, behavior, and chemical safety.

But there are a few other general lab hazards we need address,

Keep in mind that many pieces of equipment in the lab operate at very high voltages.

So keep water and liquids away from instruments.

Never attempt to repair or open any cover while an instrument is plugged in.

and only use approved extension cables or power switches.

Many lab instruments, like the autoclave, operate at high temperatures and can cause

Use heat-resistant gloves whenever handling hot materials.

If you're using the GC-MS, lower the temperature set points before opening the cover.

Extremely low temperatures can also damage unprotected skin.

Wear insulated gloves when handling dry ice or items stored in the minus-80 degree freezer.

Slips, trips, and falls can cause very serious injuries.

Most of the time, these hazards can be avoided.

Keep floors and routes of movement through the lab clear of any obstructions.

Never place any materials or instruments on the floor, not even temporarily.

Clean up spills immediately and use "wet floor" signs to warn your colleagues.

Look out for shelves, table tops, or any other structures

that could cause a head injury if you bump into them.

If they're damaged, the cylinder may be propelled at extremely dangerous speeds.

Some gas cylinders, such as hydrogen, are also extremely flammable.

Secure gas cylinders with a heavy-duty clamp and strap.

The cylinder's head should be sealed with a threaded protective cap

However, serious even fatal accidents can and do occur.

You can do your part to minimize the risk of both minor and major accidents by following

Keep an eye out for your coworkers too...make sure they're working safely.

Good science begins with safe science. Be safe. So long.
