====== Health and Safety ======

===== General Health =====

As part of RWTH Aachen University, MCh encourages all staff members to keep general track on health. RWTH offers a braod range of University Sports, where every staff member may take part.
Traditionally, staff members of MCh play football once a week, mostly on Fridays (see MCh Sports).
On the target for reducing the annual impact on flue-like diseases on MCh staff we installed hand desinfection spenders in the rest rooms. We strongly recommend to use these regularly.

===== Security =====

At RWTH Aachen security is maintained by the RWTH Security Guards located in the main building.

The RWTH Guards are checking buidlings by night and are available 24/7.
The automatic main building doors are open from 8:00 to 17:00, generally. Outside this time you will need a key to enter the building.

The automatic floor doors on the 2nd and 3rd floor are activated in the morning around 7:00 and are deactivated in the afternoon, generally around 16:30.

===== Safety =====

Work safety is essential for MCh since we are a research institute where experimental setups are continuously modified and a number of potentially hazardous materials are used in the labs. As already stated, **new personnel** (disregarding whether it is a HiWi, Ph. D., or a new workshop worker) **cannot start working in the MCh laboratories prior to receiving the safety instructions** fully covering their intended field of work. Please make appointments with the following persons (//last updated: May 2024//):

^ Safety        ^ Required for        ^ Responsible person                       ^

| Lab/electric  |                     | Bernd Conrad, control engineering        |
| Radiation     | work with XRD etc.  | Bernd Conrad, control engineering        |
| Laser         | work with MOS etc.  | Bernd Conrad, control engineering        |
| Chemical      | work in labs        | Michal Fečík                             |

Safety data sheets (SDS) for compounds used within MCh (both laboratories, and workshop) can be found on our internal server (//currently "under construction", May 2024//):

<code>

Most of SDS are only in German; therefore, do not hesitate to ask for help if you do not understand something! If you find there is an SDS missing, contact people responsible for handling chemicals and/or chemical safety instructions - see persons responsible for [[mchadmin:responsibilitysafety|chemical safety]] or [[mchadmin:responsibilityother|chemical laboratory]] - to discuss further steps.
