Integrated Safety Management

1. General rules• Inform yourself about potential dangers you might deal with.

• Think about what to do in case something goes wrong.

• Eating, drinking in the labs is forbidden.

• Alcohol drinking and smoking in the labs and offices is forbidden.

• Close windows, lock labs and rooms if nobody is inside!

• A collection of Material SafetyData Sheets (MSDS) includingalso information on risk (R) andsafety (S) is available in room 414(A. Setzer).

• Take a look at the packing, dangerous compounds are marked by symbols.

• Dangerous compounds must be signed to prevent mistaken.

• Avoid skin and eyes contact with chemicals, use personal protective equipment (PPE).

• Use the fume hood!

• After using the fume hood, clean the place. It is no storage room.

• Recycle organic solvents black containers

• Acids, bases, other inorganic chemicals in white plastic containers.

• After finishing your work, clean and make the space free.

• If something is damaged/destroyed, inform immediately theresponsible people or someone who can help to fix the problem.

2. Fire prevention

• Behave appropriately to prevent fire and damage! Personsusing devices/instruments: stay strictly to use specifications.

• Defects in fire protection must be notified to the personresponsible for security (P. Lorenz) or the "Dekanatsrat" (M.Schaefer).

• No smoking in every lab, seminar room, lecture hall etc.

• Running Coffee machines is only allowed inlounges and bureaus, nowhere else.

• Flammables should only be stored at an amountneeded for one work day in the respective lab orwork rooms.

In Case of Fire or Smoke

• The building doors can be closed but not locked.

Escape Ways

• Don't put anything that can block the escape way or areasnecessary for rescuing marked in the "Flucht- und Rettungsplan".

• Signs of the escape ways must not be covered.

• Every person who has no responsibilities in case of fire mustleave the building and go to the 'Stellplatz' for a presence count!

Fire Report

• Press the fire alert button. The alert is forwarded to a central technicaldepartment. Another alert is induced by smoke sensors.

Fire Extinguishers

• Use the 'Rettungsplan‘ to find them. Appropriate to extinguishsmall fires. They must not be covered!

Alert Signals

• Fire alert takes place by sound of hooters.

Behavior in case of fire

• 1. Don’t panic

• 2. Rescue life

• 3. In case of alert, call the dispatcher

• 4. In case of fire without alert, inform the fire department/dispatcher

3. Compressed Gas cylinders

• Never store and use them lying on the floor.

• Avoid storage near to heat sources. Don't heat gas cylinders.

• Oxygen cylinders must be stored 6 m from combustible materialsor flammable gas containers.

6 m

O2

• Fasten cylinders securely while in storage.

• Use the valve protection cap when moving a cylinder.

• Use a suitable hand truck or dolly for transporting cylinders.

• Before removing a regulator, close the valve and release the gas from the regulator.

4. Electrical equipment

• Check the electrical insulation of pipes, sockets etc. before starting the experiment.

• The assembly or modification of electrical circuits must always be done with the power off.

• Set up the circuits clearly.

• Discontinue the current flow immediately in electrical accidents.

• Every electric shock victim is considered tobe seriously injured and has to be providedappropriate medical assistance.

• Testing of electrical devices (deadlines: 1year, half a year)

5. Laser Safety Instructions

1. Scope minimization principle:

• From simple screening oneself up to a completebody protection measures

• Keep the course of the laser ray as short andcompact as possible

• Optical equipment should be fastened carefully

• At the point of impingement of the beam make sure itwill not cause any harm (absorption, diffuse reflection)

• To have the laser beam above or underneath the eyeswould best answer the safety purpose for the eyes

• No optical axis in direction to the window

• Furniture of the room, windows, floors should reflect the laserbeam diffusely

• Same goes for clothing, watches, tools etc. For example, useblack lacquer spray for blackening

2. Mode of operation

• Even when already wearingprotection glasses: do not look intothe laser ray

• Use only the protection goggles thathave been produced for the usedlaser (wave-length, attenuation,producer)

• Goggles for laser adjustment shouldbe used up to 10 W only

• Eye damage - what to do, whom to call?

• If one of your eyes got into contact with a laser ray, it can beassumed that there was caused serious damage. An eye specialistshould do a "Fluoreszenzangiographie".

• The eye clinic of the Leipzig University is able to do such a checkup.

Ambulance phone: (0341) 97-21488

(every day 7:15 am - 12:00 am, laser

checkup from 1:30 pm - 2:15 pm.)
