 ====== Safety Regulations ======
-Everyone working in the Bio SPM Lab should have received the LION safety regulations and have read them thoroughly. \\  ([[http://www.physics.leidenuniv.nl/divers/Webversie_mei2005.pdf]]). \\
+Everyone working in the SPM Lab should have received the safety regulations of the Leiden University and have read them thoroughly. \\
 The faculty course about chemical safety should be followed as well as the fire extinguishing drill (follow these at the first opportunity).\\

-===== General =====
-The general idea is: if you are not sure, //ask//. Some of the situations you can encounter where you should consider your safety are: chemicals, high voltages, RF radiation, heavy objects, sharp objects etc.
+===== Biological samples =====
+Some biological samples (like human tissues) require special procedures. The LION SPM Lab is NOT a MLx laboratory! It is not allowed to bring biological hazards in the AFM lab.
+There are procedures that can enable you to carry out experiments on biological samples/human tissues in the SPM Lab in a proper and non-dangerous way. You are obliged to contact laboratory staff (<galli@physics.leidenuniv.nl>) before carrying out experiments on biological samples. We can instruct you on how to perform your experiments safely.

 ===== Chemicals =====
-Be //very// careful to avoid eye contact with all chemicals. If you get strong alkalies in your eye your vision will almost certainly be damaged! Avoid all skin contact with innorganic chemicals (acids and bases) and avoid their vapours by working in a fume hood. Avoid skin contact and especially inhalation of organic chemicals by working in a downflow bench, cleanbench or fumehood (you can find many in the [[http://msm09.physics.leidenuniv.nl/|Nanolab]], located on the 6th floor. Prior usage, ask to Marcel Hesselberth (<hessel@physics.leidenuniv.nl>, tel:1887) for permission.)
-Always hold a bottle with 2 hands and never even think of just holding the cap. Some organics require evacuation of the building if you drop a bottle! If a bottle breaks and chemicals are spilled there may be an explosion danger. Walk to the 3 button wall panel and switch all 3 buttons off so that the room is completely shut down, then warn the floor coordinator (<oosterkamp@physics.leidenuniv.nl>, tel:5424).
+It is NOT ALLOWED to use chemicals in the SPM Lab apart from the provided ethanol, acetone, isopropyl alchool and demi-water.\\
+Extensive sample preparations should NOT take place in the SPM Lab. We have both clean room and chemical labs close by. Please contact laboratory staff for their use.\\
-Each cleanbench / downflow bench / fume hood has an eye shower on top. Eye showers are single use! Do not twist the cap out of curiosity, once opened they cannot be closed and must be discarded. If you get covered by chemicals there are showers in the hall on each side of the floor.
-MSDS's of all used chemicals are present.

 ==== Inorganic chemicals ====
-Use demi water for making etch chemicals, NEVER normal water! Demi water is a chemical, do not drink it (it depletes you of minerals).
+Do not drink demi water. It depletes you of minerals and can be lethal.
 === Acids ===
-When working with acids, always wear gloves and work behind the glass of the downflow bench / fume hood or wear safety glasses (available in the 'magazijn'. If you work with HF **be extremely careful**. HF is not a very strong acid but it is exceptionally destructive. A small area of the body covered with HF is lethal. The only way to neutralize HF is with Ca, it is obligatory to have Ca pills or creme close when you use HF. Be careful when disposing strong acids, strong exothermal reactions can occur upon mixing with other chemicals.
+IT IS NOT ALLOWED TO WORK WITH STRONG ACIDS IN THE SPM LAB.\\
+AN EXCEPTION is done for Electrochemistry SPM experiments. People who plan to perform these experiments should contact laboratory staff (<galli@physics.leidenuniv.nl>) before starting!

 ===== High voltages =====
 Many systems work with very high voltages, and in some cases HV power supplies can deliver significant current (several amps).
-The systems are equipped with protection circuits but these can never cover all possibilities, so when you disconnect power supply cables to connect them to a different sputtering source for example or when you open vacuum systems be //very careful// that the mains are switched off.
+Never open the electrical equipment in use in the AFM Lab. This is done exclusively by the lab manager.
 Also be careful with water leaks in electrical systems and with jewelery (a necklace can dangle through the ventilation slits of an electric box and is therefore not allowed).
+If you are planning to use electrical equipment with the microscopes that is not available already in the lab, this should be either CE certified or built in our Electronic Department.
