Safety structure

Richard Egberink, Marcel de Bruine, Clemens Padberg and Christiaan Breukers are the people who have a first aid diploma. There is a plaster box in every lab. Dial 2222 in case of emergency.


The (bio)chemical work within Molmat Department is divided over 4 different laboratories.. Members of each of these laboratories are responsible for the order and cleanliness of their own lab, the general equipment (rotavaps, ovens, pumps, vacuum line, balances etc), the general fume hood (waste hood), cupboards etc. Everybody has to empty their own fume hood from solvent bottles and chemicals before going home every day. This means that only a leakage box and general set-ups can remain in the fume hoods. Fume hoods should be entirely closed when not at work or in the ‘werkstand’ for optimal extraction of air. On the bench only pre-cleaned glassware is allowed.

When a person or a lab frequently does not comply with these general rules measures will be taken. The measures range from organizing the Friday afternoon borrel, paying a coffee-plus or a borrel, cleaning out the waste room, organizing the biannual lab-cleaning, to forbid someone entrance to the lab or the building.

The responsibility lies with the lab-members themselves how to organize this!


Everybody that wants to use equipment in our labs need a proper introduction on the machine before they start using it. On our websites or is a list with equipment responsibilities and locations. (see also Appendix C). The indicated person takes responsibility for general cleanliness of the apparatus and direct working area and the general introduction of the apparatus (you are only granted access, and allowed to make reservation after this introduction). This person can urge people to clean and take care of the equipment.

Safety glasses

You are obliged to wear safety glasses inside the Laboratories! Normal safety glasses can be obtained from the technicians. If  you need special glasses when you wear prescription glasses in daily life, please contact the safety officer (Wim Verboom). He can give permission to buy special glasses from an Optician.

Safety gloves

Different gloves have different applications:

The use of gloves is only allowed in the labs to prevent contamination of door handles, other furniture, computers and equipment. If you need to move from one lab to the other, please remove at least one glove so you can open the door with the free hand. Do not contaminate the door handles.

Safety synthesis

Different regulations are operative depending on the location:

ML-1 labs

These labs have limited entrance and are only inspected by their inhabitants (see Appendix D).

Laser labs

This lab has limited entrance and inspection takes place by the responsible persons (see Appendix E).

Storage room

Openings hours stockroom CR4222: 11.15 – 11.45h

Washing room

Inspection takes place by the responsible labgroup as stated on the corvee-list . Check the state of cleanliness of the freezers, fridges, SPS system, MilliQ system, dishwasher, ultrasone baths, autoclave, ice machine etc.

Working outside office hours

When working outside office hours (18.00 - 8.00 on weekdays and the entire weekend), your entrance pass/keys needs to be activated to be able to enter and leave the building/floor. Activation takes place (1) after the safety introduction and (2) after the general introduction for new employees of the faculty (AMH).

General rules:

  1. The safety of the experimenters must be guaranteed
  2. Experimental work must be allowed to go on as much as is reasonably possible
  3. Proper response to a calamity is only possible when at least two persons (one must be PhD, Postdoc or technician) are present during chemical activities.

Some special rules:

  1. In case you want to perform reductions with H2 please contact Richard/Marcel.
  2. Cyanide protocol 
  3. Piranha protocol 
  4. Aquaregia protocol

Experiments outside office hours

A number of conditions must be met in order to do experiments in the lab outside normal office hours.

  1. The experimental setup must be safe and uncluttered. No containers with inflammable materials next to the setup is allowed.
  2. Use plastic tubes of good quality and fasten them with tube connector clamps
  3. Use electrical equipment of good quality
  4. Working at temperatures above room temperature is only allowed in combination of magnetic stirrer, oil bath and contact thermometer
  5. Do not perform experiments with fire hazard or the possibility of developing stinking fumes
  6. Prepare the setup well ahead of time, so you can make a dry run
  7. Let a senior person of your lab check the setup
  8. Have a permit signed by an authorized person. (labmanager)
