Early intervention with small fires can prevent catastrophic big fires. Do you know how to use a fire extiguisher?

PECVD Gas emergency Stop Fire Alarm

       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?

First aid chemicals

       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.

Fire Exits

       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.

Mandatory equipment during use of chemicals

        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.

    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.

  Eye protection  The use of glasses.

 The use of masks.

  The users of contact lenses. Beware!

Respiratory protection  The use of oxygen masks.

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.

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

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

  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

 Type of safety threat?

▪ Corrosive ▪ Explosive ▪ Flammable ▪ Irritative ▪ Reactive ▪ Senstizer ▪ Poisonous

   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

    Keep all chemicals closed and labeled. If in the beaker don’t 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.

  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

 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

 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.

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

   Separate oxidizing inorganic acids from organic acids or flammable materials.

Organic acids are flammable. Perchloric ascid ve picric acid requires special care. r.

 Class 1: Continuous watching harmless. Packed as no one can reach.

Low-power lasers or high-power lasers in the indoor environment.

 Class 2: Normally harmless but during the long exposure it would be harmful.

Power: < 1mw

 Class 3a: Harmless exposed to short term. But dangerous if collimated.

Power: < 5mW (Laser pointers)

 Class 3b: Direct or reftected exposure harmdfull but its scttared light not as harmful.

Power: < 500mW High power pointers He-Ne lasers

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

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

     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+

 Retinal damage more serious then cornea. Savely use Cornea damage Retinal damage

    Fire hazard Electrical circuits Gases and flammable vapors To solvents.

   Gas Hazards Plastics!

Gas lasers gases

 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.

      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..

  While working in a laboratory security ALWAYS should be kept at the forefront.

Otherwise your life (even worse of a friend) can cost lives.
