6. Advice A workplace specific instruction can be created in parts from this operating instruction. In any case it has to be modifified and upgraded to the needs of the indiviual workplaces of the different working groups.

7. Basics principles • Generell opening hours: 7.00-18.30 (main entrance) • Access: only legitimated persons • Smoking ban in the whole building • Tidiness in offices and laboratories • Use of workshops (fine mechanics & electronics) only in the opening hours • Don´t listen to music during work, you might not hear a fire-alarm or other warnings

8. Basics principles Nonsmoker – Yes, please! Stop smoking – it´s worth it because after • 20 minutes regularizes blood-pressure and pulse • one day the risk of a heart attack is reduced • two days the senses of smell- and taste improve • three months the blood flow improves • one year the risk of a cardiac disease reduces about 50 % • five years the risk of a stroke or lung cancer is significantly reduced

15. Ergonomics of a Computer workplaceBildschirmarbeitsplatzverordnung Five rules for ergonomical seating: • Rule: Arms and legs can be held in a right angle • Rule: use full seating area 3. Rule: Sit upright and use seat back 4. Rule: Sit dynamic, move! Take exercise 5. Rule: Use arm and backrest and handrest

16. Ergonomics of a Computer workplaceBildschirmarbeitsplatzverordnung Alternative Office Furniture • Ergonomic analysis advises to dynamic sitting, it strength the back and prevents painful discomforts • Dynamic sitting is easy! Just use alternative office furniture like gymballs, kneeling chairs etc. • BUT!
