2 Personal well being Well being of others in the lab. The safety of equipment.

3 First to call numbers Health Center 6666 0-312-290 6666 Security 1234 0-312-290 1234

4 Fire General alb accidents Chemical accidents Optical accidents Biological accidents Nuclear accidents Earthquakes

5 Close doors and windows Shut down air conditoning. Sound the fire alarm Notify (290) 1234 Secure injured Notify (290) 6666 vya 1666 for injured Attempt to extinguish the fire only if you are not in danger yourself. Do so with a fire extinguisher. Early intervention with small fires can prevent catastrophic big fires. Do you know how to use a fire extiguisher?

6 PECVD Gas emergency Stop Fire Alarm

7 Shut down air conditioning in case of gaseous, or liquid chemical contamination. Notify authorities. In case of splash on your garments, take them off immediately. Wash affected area with running water for at least 15 minutes. Call 6666. Use acid neutralization kit. If the area is safe, use eye wash or body wash showers. Cleaning up is done with professional teams. But if you can shut down the source of the contamination without putting your self in danger, please do so. Do you know how to use and oxygen cylinder or a flee mask?

8 First aid chemicals

9 Know where the lab exit doors are. Know the location and the use of safety showers. Know the location of fire alarm buttons. Know the location of the nearest phone. Know the hazards of the materials and equipment you use. Read MSDES files for the materials you use. Consult internet for further info. Do NOT work before taking necessary precautions. Do NOT use materials you do not know and equipment you are not trained for. Consult M. Gure when necessary. Those who are not approved by Murat Güre can not enter class 100 lab.

10 Push Handle Pull Body and eye showers

11 MSDS files and flee mask

12 CLASS 100 escape doors

13 Fire Exits

14 Do NOT enter the lab without gloves, gogoles, clean room garmentsEldiven, gözlük, elbise gibi gerekli teçhizatı kullanmadan laboratuvara girmeyiniz. Do NOT eat, drink and smoke in the lab. You are discouraged from wearing makeup in the lab. Long hair must be tied in the back and taken into a hair net. Drooping metal necklesses, arm bands or bracelets should NOT be worn in the lab. Short slacks are NOT allowed in the lab. Use a lab garments. Do NOT use your mouth for pipette action. After you leave the lab, wash your hands and check yourself for possible chemicl splashes. Do NOT use short cuts during the experiment. Use equipment suitable for the task.

15 Mandatory equipment during use of chemicals

16 Do NOT touch any equipment without the permission ofthe user. Food and drinks are stored in the refrigerator in the kitchen. No chemicals in this refrigerator please. NO food in the refrigerators in the lab. If you use chemicals that takes too long to finish the job, notify M. Gure the nature of the chemical process before starting the experiments and get approval. Read MSDS of cheimicals that you are using the first time. Do NOT leave chemicals out in the open without marking their identity and last use date. Do NOT work alone in the lab during after hours. Notify the security guard when wroking at night. Working after midnight requires special written request by your academic advisor from ARL Coordinator prior to any work. Lab security is required to check that this is done.

17 No jokes in the lab. Leave the lab clean.Do NOT leave hazradous or flammable materials out in the Use minimum quantities of chemicals when working. Do NOT store chemicals in your office or lab. Use chemical storage area for excess chemical storage. See M. Gure for this. Please notify possible hazardous situations to lab personel.

18 Eye protection The use of glasses. The use of masks. The use of oxygen masks. The users of contact lenses. Beware! Respiratory protection Notify and get approval from M. Gure for experiments that may release gasses requiring protection. Masks in the lab are flee masks. They should not be use for long periods of time.

19 Skin and body protection The use of gloves The use of lab coats and aprons The use of shoes. Protection of hearing

20 Lanibar flow benches Masks Gloves Body and eyes washes Kits against chemical contamination. Fire extinguishers

21 Minimize hazards. Safe use: Please also note the properties of chemicals, alone and in the reaction: What is the allowable amount? What is the lethal or hurmful dose? Possible ways to Chemical exposure? Contact with skin or eyes Swallowing Inhalation Injection

22 Type of safety threat? Corrosive Explosive Flammable Irritative Reactive Senstizer Poisonous

23 Safety symbols (patlayıcı) (yanıcı) (zehirli) (aşındırıcı) (oksitleyici) (kanser yapıcı)(zararlı)(tahriş edici)

24 Type of safety hazard? Acute poisoning Carcinogen mutagenic Teratogenic Physical Properties Of Chemicals Aerosol Cryogenic Dust or particle Gas Liquide Solid Vapor density Vapor Pressure Flammability Chemical Compatibility

25 Keep all chemicals closed and labeled. If in the beaker dont keep more than an hour. Keep it at minimum amount if possible. In Markup: Name of the chemicals Hazard Warning Name and tel. Of the user. Date.

26 Do not store incompatible chemicals together. Flammable Chemicals Flash point less then 38 C can be flammable. Flash point between 38-94C can burn. Like: Benzene Alcohols Hydrogen sulfide Acetone Ethers Organic acids

27 Corrosives Acids Oxidiser acids Perchloric acid Chromic acid Nitric acid Sulfric acid Mineral Acids Hydrochloric acid Hydrofloric acid Phosphoric acid Organic Acids Acetic acid Formic acid Butyric acid Propionic acid Picric acid Acrilic acid

28 Keep away the acids from bases and active metals. Like, potassium, magnesium. Keep away the acids from pissoning vapor producer chemicals. Keep away the acids from tolune and xylene. Do not full up the bottles.

29 Bases Reacts strongly with acids. They cause corrosion. Ammoniyum hidroksit Sodyum hidroksit Kalsiyum hidroksit Organik aminler Poisonous chemicals Should be kept in ventilated enclosures. Fosfin Arsin Osmiyum tetraoksit Dimetil sulfat Toluen 2,4-Diisosiyanat Sodyum azid 37% formaldahit

30 Separate oxidizing inorganic acids from organic acids or flammable materials. Organic acids are flammable. Perchloric ascid ve picric acid requires special care. r.

31 Reactive-Oxidizers Fire and explosion hazard Halogens Ammoniumpersulfate Hydrogen peroxide Sodium dichromate Potassium permanganate Perchloric acid Ammonium nitrate

32 Reactive Reductants Ammonia Carbon Metals Metalhydrades Phosphorus Silicon Sulphur Keep away from the oxidisers.

33 Water-reactive Chemicals Sodium Potassium Calcium carbide Phosphoruspentachloride Peroxide Producers Diethyl ether Tetrahydrofuran Acetaldehide Isopropyl ether

34 Avoid contact with eyes and skin. Do not use liquid nitrogen without eye glasses or protective mask. During the transportation of LN use the protective gloves and eye glasses to avoid skin touch and prevent the face.

35 Equipment for handling liquid nitrogen

36 Toxic Flammable Phyrophoric Explosive Reactive Corrosive Oxidiser Choking

37 High pressurized gases 100-2500 psig DANGEROUS! Slow action to cylinders. Do not move without covers! The cylinder should be kept shackled to the wall! Use proper ragulating valve. Do not use damaged cylinders. Label them as empty or full.

38 Threshold limit value - Time weighted average (TLV- TWA): average exposure on the basis of a 8h/day, 40h/week work schedule Threshold limit value - Short-term exposure limit (TLV-STEL): spot exposure for a duration of 15 minutes, that cannot be repeated more than 4 times per day Threshold limit value - Ceiling limit (TLV-C): absolute exposure limit that should not be exceeded at any time

39 Take the chemicals safety. Valves, lasers, power supplies should be closed. Depremde devrilecek malzeme olmamalı. In Case Of Earthquake Please secure yourself first. Please do not leave the building during the earthquake.

40 Optical accidents: Eyes Skin High Voltage Sources Current Sources

41 Class 1: - Continuous watching harmless. - Packed as no one can reach. - Low-power lasers or high-power lasers in the indoor environment.

42 Class 2: - Normally harmless but during the long exposure it would be harmful. - Power: < 1mw

43 Class 3a: - Harmless exposed to short term. But dangerous if collimated. - Power: < 5mW (Laser pointers)

44 Class 3b: - Direct or reftected exposure harmdfull but its scttared light not as harmful. - Power: < 500mW - High power pointers - He-Ne lasers

45 Class 4 - Fully harmful - power >500mW - Eye and Skin damage. Fire causes.

46 Eye or skin damage Fire Toxic gases in gas lasers High Voltage

47 Exposure to Skin or eye to the Laser Direct exposure Reflected light (400nm – 1400nm) permanent damage to the retina.– Nd:YAG, Yb fiber, Cu-vapor, diode, HeNe,Ar+

48 Retinal damage more serious then cornea. Savely useCornea damageRetinal damage

49 Fire hazard Electrical circuits Gases and flammable vapors To solvents.

50 Gas Hazards Plastics! Gas lasers gases

51 Lethal High Voltage Most of the accident! ALTHOUGH power has been turned off the shock! No metal goods on your body. Do not stay on the wet floor.

52 Protect your eyes, as appropriate. Put the Lab entrance alert. Put the optics low as much as possible. Strong ambient lighting. So the narrow retina diameter. Keep airconditioners open. Do not touch exposed cables, etc..

53 While working in a laboratory security ALWAYS should be kept at the forefront. Otherwise your life (even worse of a friend) can cost lives. Please be careful!
