1. Safety at work

The University of Bremen is responsible for the health and safety of its employees. Therefore the employees have to be trained by an yearly safety instruction.

The participation has to be proved by signing a list at the end of this presentation.



AG Burrows

Laws, rules and regulations:

• the law of safety at work ( Arbeitsschutzgesetz)

• rules for accident preventions (Unfall VV)

• chemicals act (Chemikaliengesetz)

• regulation of dangerous goods (GefStoffV)

• technical rules for dangerous goods (TRGS)

for further information see:

AG Burrows

Safety in the lab

If you are working in a lab at the University of Bremen you have to follow the “General Laboratory Policies” (Laborrahmenordnung).



AG Burrows

Important points of the “General Laboratory Policies”:

• Eating, drinking and smoking is forbidden in the lab.

• Keep the labs clean and orderly.

• Be familiar with the safety equipment and its usage.

• Protective clothing has to be worn (if required).

• Turn off defective devices immediately.

• During general blackout, only use exhaust hoods connected to the emergency power grid.

• If no longer needed, turn of all gas, water and air lines.

• Use the emergency switch in case of a accident due to fire or electricity.



AG Burrows

Working in the lab:

• Ensure that the ventilation in the lab is switched on and the windows are closed.

• Escape routes to exits, windows, eye wash etc. have to be wide enough (min. 0.8 m) to handle emergency situations.

• When leaving the lab, close the windows and lock the door for safety reasons and to prevent theft.

When you are working alone at late evening or at the weekend:

• Inform your team leader before working alone.

• Agree with your team leader, how to ensure that you are fine, e.g. a call by a colleague at a specified time.



AG Burrows

Potential danger Example Protective action (to be continued)

Fire Burning of paper, cart boxes etc.

- No open fire- Keep escape routes free of flammable

parts

Electrical shock 230V: touchable electrical parts

- Switch off power before repairs- Use covers and warning signs

Heavy loads Gas bottle falling down

- Put gas bottles in the gas cabinet- Lash gas bottles with strings

Explosions Wrong handling of gas bottles

Always cover the fittings with the cap during transports

Rotating machine parts

Drill press in Electronic-Lab

Use these machines only when you are informed about the safety instructions

Toxic gases CO intoxication - For storage use gas cabinet only- Assistance by a second person

Acids / Bases Acid burns Use gloves, glasses etc.

Laser Eye injuries - Wear eye protection - Switch on laser warning light



AG Burrows

Examples of safety equipment at the IUP



AG Burrows

Laser

If the laser warning light is switched on, do not enter the lab without permission.

The laser safety representatives at AG Burrows are:- K. Gerilowski- M. Horstjann



AG Burrows

In case of situations which are abnormal or if you see any damage in the lab, please inform immediately:

• the person in charge for the lab / device

• the person in charge for security(safety instructors for AG Burrows: K. Gerilowski / W.

Thomssen)

• one of the building technicians (GBT, Tel. 60669)

• the supervisors of the IUP (J. Burrows, J. Notholt)



AG Burrows

2. Handling of dangerous goods

The dangerous goods representative (Gefahrstoff-beauftragte) for the IUP AG Burrows is:

M. D. Andrés Hernández (Room U3135)

Save handling:• Store chemicals in the designated cabinets.• Store acids and bases in separate cabinets.• Do not store chemicals in your office.• Use personal protective equipment (glasses, gloves etc.)



AG Burrows

Introducing, ordering and checking of new chemicals:

• Is it compatible with chemicals already used?• What about the safe storage?• What about the disposal of contaminated waste?• Is the current issue of the material safety data sheet

available?• Is the person working with it familiar with the safety

instructions?

Inform the safety instructor and the dangerous goods representative. Send them the Material Safety Datasheet.



AG Burrows

The Material Safety Datasheet (MSDS / EG-Sicherheits-datenblatt) for chemicals …

... has to be at every working place using dangerous goods (visible for everyone)

… has to be at the storage area

... describes the chemical and its handling

... describes the actions in case of an accident

... has to be immediately available

… are made available by the person who is in charge of the equipment



AG Burrows



AG Burrows

Only do the following actions with assistance by a second person:

• Changing bottles with dangerous gas and works on the gas systems.

• All duties which include handling of dangerous goods.

• Works which are classified as very dangerous as working on High Voltage or with 380 V.
