Report incidents and accidents

What are you supposed to do if something goes or has gone wrong? Whether it be a break-in, an accident or an unsafe situation of any other kind, or data breach or cyber-attack; please read how to report each type of incident below.

When every second counts

For emergency assistance, calamities or immediately threatening situations, call the emergency number of your building (please refer to your telephone). If you are outside, call 112.

Please mention your name, phone number, the nature and location of the incident and possible victims. Through your input we can learn from incidents and include it into the (security) policy of the university.


If there is no urgency, report the (potential) incident within 24 hours at one of the departments mentioned below. Please mention your name, phone number, date, time, nature and location of the incident and possible victims. If  you are in doubt as to which department to contact, choose the department that seems most appropriate for the incident you want to report. The department staff will pass your report on to the right department, who will then take action.

A hazardous situation or near-accident is an event that, under less favourable circumstances, could have led to injuries. This includes an increased risk of fire or explosion, falls and other impacts, or an electric shock. You should report accidents that have not yet caused severe injuries to the Health and Safety Coordinator of your location and by means of the online report form.

If the incident is a work-related accident that has resulted in injuries, call your building’s emergency number (please refer to your telephone). If you are outside, call 112. Afterwards, report the incident by filling out the online report form within 24 hours.

Reporting damage during office hours

It is important that damage to a university building is reported as soon as possible. You can report damage using this form. You can only access this form with a ULCN account. Employees and students without a ULCN account can report damage by mailing verzekering@vastgoed.leidenuniv.nl. You will then receive the form via email.

If you have trouble filling in the form, contact the Service Desk in your building. If your building does not have a Service Desk or if you urgently need to speak to someone directly, you can report the damage by calling (90)1191. If there is no answer, please contact (90)3029 of 06-14338425 or send an email to verzekering@vastgoed.leidenuniv.nl

Reporting damage outside office hours

In urgent cases outside office hours (5.30 PM - 8.30 AM), please call Huschka’s emergency number: 071 402 0401. In case of a real emergency, call 112 first.

If you have been exposed to dangerous chemicals, biological agents, genetically modified organisms, radioactive substances or (ionising) radiation, please call your building's emergency number (refer to your telephone). If you are outside, call 112. 

Needlestick and cutting injuries bring you in direct contact with another person's or animal's blood or other bodily fluids. This may be caused by piercing or cutting, but also by splashes or bites. If this happens, contact our university doctor immediately by calling 071 527 8015.

A threatening situation could involve (attempt to) break-in, theft, violence or threats by another person. Report threatening situations to:

Contact safety department Phone
Marte Boonen 071-5273184
Jaap van Zaanen 071 527 3802


If it is an emergency incident, call your building’s emergency number (please refer to your telephone). If you are outside, call 112.

Outside opening hours, report incidents to our mobile surveillance:

  • Leiden: 06 26 97 50 16
  • The Hague: 088 298 1500

They will assess the situation on our behalf if, for instance, you notice the consequences of a burglary attempt, such as broken windows, lights that are not supposed to be on or anything else that is out of ordinary around the building.

Unacceptable behaviour involves harassment, aggression, discrimination in the workplace, infringement of scientific integrity, or other kinds of abuse. Such incidents relate to abnormal behaviour that raises questions or causes distress or anxiety to you or others.

Unacceptable behaviour can be reported to one of the university’s confidential counsellors. In the event of an emergency, call your building’s emergency number (please refer to your telephone). If you are outside, call 112.

Your report will be registered and handled anonymously, and with strict confidentiality. Your input is important: we can learn from incidents, and include your input in the University's security policy.

A data breach occurs when personal data gets into the hands of third parties who should not have access to the data, or when personal data are lost unintentionally. Report data breaches to the ISSC Helpdesk (call 8888). If in doubt, contact the data protection officer.

Cybercriminals manipulate company systems using viruses, malware or other means. They try to steal your login details, study details or research data, in order to sell them or use them for their own purposes. Company information, such as finances or processes are also the target of cybercriminals. You could, for instance, receive fake emails on behalf of Leiden University and become a victim of phishing. Report cyber crimes to the ISSC Helpdesk (call 8888). If in doubt, contact your faculty’s information manager.

If you are staying abroad for work you can call for help and advice in case of an emergency via one of our crisis telephone numbers:

+31 71 5 27 66 66
+31 320 33 13 43

These phone numbers are available day and night.
