Access to KAUST University laboratories, workshops and other work areas housing hazardous materials or machinery is restricted to the relevant University faculty, staff, students, or other persons on official business.
Visitor guidelines, visiting scientists, open houses and tour guidelines are published on this page.

Visitors and Children in Labs

Due to the potential hazards and liability issues, other persons (in particular children under the age of 16) are not permitted in hazardous work areas, with the exception of KAUST-sanctioned activity, e.g., tours, open houses, or other KAUST-related business as authorized by the Principal Investigator or laboratory manager. In these instances, all children under the age of 16 must be under careful and continuous supervision. If a Principal Investigator or laboratory manager authorizes visitors or children to enter a hazardous work area, then that Principal Investigator or laboratory manager


is responsible for the health and safety of those individuals.

Visiting Scientists and Other Similar Users

There are potential risks associated with allowing access to labs and equipment by visiting scientists. These risks include theft or questions of ownership of intellectual property, bodily injury, and property damage. Departments should verify that all users of the lab have the required safety and health training and competence prior to allowing access to the lab and/or specialized equipment. It is the userʼs responsibility to have or obtain the appropriate training.


It is the responsibility of the center directors, Principal Investigators, and laboratory managers to ensure visiting scientists and other similar users have been properly trained and made aware of any potential health and physical hazards that may exist in their labs.

Laboratory tours and open housesd does not guarantee adequate protection. The fume hood must be used properly.

Pets In Labs

Pets are prohibited in KAUST laboratories. In addition, while on University- controlled property, animals must be attended and restrained at all times.
It is the responsibility of the center directors, Principal Investigators, and laboratory managers to ensure visiting scientists and other similar users have been properly trained and made aware of any potential health and physical hazards that may exist in their labs.

Eating, Drinking and Applying Cosmetics In The Laboratory

To prevent exposure to hazardous materials through ingestion, do not eat, drink, chew gum, or apply cosmetics in areas where hazardous materials are used. Wash your hands thoroughly after using any chemicals or other laboratory materials, even if you were wearing gloves, and especially before eating or drinking.


To help promote awareness, laboratories refrigerators and freezers should be properly labeled. Refrigerators used for the storage of chemicals should be labeled “Chemicals Only, No Food”. Examples of these signs can be found on the Signs and Labels webpage.


Keep in mind that some chemical exposure can result in immediate effects (acute exposure) while other effects may not be seen for some time despite repeated exposure (chronic exposure). Consuming food or drink or applying cosmetics in the lab can result in both types of exposure.

Personal Hygiene

Good chemical hygiene practices include the use of personal protective equipment (PPE) and good personal hygiene habits. Although PPE can offer a barrier of protection against chemicals and biological materials, good personal hygiene habits are essential to prevent chemical exposure, even when using PPE.

Some general guidelines that should always be followed include:

01

Do not eat, drink, chew gum, or apply cosmetics in a lab or other area where chemicals are used.

02

Do not store food or drink in refrigerators that are used to store chemicals.

03

Do not ever try starting a siphon or pipette by mouth, doing so can result in ingestion of chemicals or inhalation of chemical vapors. Always use a pipette aid or suction bulb to start a siphon.

04

Always confine long hair, loose clothing, and jewelry.

05

Wear a lab coat when working with hazardous materials.

06

Shorts, skirts, sandals, and open toed shoes are not permitted in KAUST laboratories.

07

Remove laboratory coats, gloves, and other PPE immediately when chemical contamination occurs. Failure to do so could result in chemical exposure.

08

After removing contaminated PPE, be sure to wash any affected skin areas with soap and water for at least 15 minutes.

09

Always remove lab coats, scrubs, gloves, and other PPE before leaving the lab. Do not wear lab coats, scrubs, or other PPE (especially gloves) in areas outside the lab, particularly not in areas where food and drink are served, or other public areas.

10

Always wash hands with soap and water after removing gloves and before leaving the lab or using items such as the phone, turning doorknobs, or using an elevator.

11

Always wash lab coats separately from personal clothing. Be sure to identify contaminated lab coats to commercial laundry facilities to help protect their workers by placing the contaminated lab coat in a separate plastic bag and clearly identifying the bag with a note or label indicating the lab coat is contaminated.

Laboratory Security

The following are guidelines designed to minimize opportunities for intentional removal of any hazardous materials from your laboratory:

01

Recognize that laboratory security is related to, but different from laboratory safety. Security is preventing intrusion into the laboratory and the theft of equipment or materials from the lab.

02

Develop a site-specific security policy. Make an assessment of your laboratory area for hazardous materials and particular security issues. Then develop and implement lab security procedures for your lab group and train lab group members on security procedures and assign responsibilities.

03

Control access to areas where hazardous chemicals are used and stored. Limit laboratory access to only those individuals who need to be in the lab and restrict off-hours access only to individuals authorized by the Principal Investigator.Be sure to lock freezers, refrigerators, storage cabinets, and other containers where stocks of biological agents, hazardous chemicals, or radioactive materials are stored when they are not in direct view of workers (for example, when located in unattended storage areas). Do not leave hazardous materials unattended or unsecured at any time. Most importantly, close and lock laboratory doors when no one is present.

04

Know who is in the laboratory area at any given time. Approach anyone who you donʼt recognize and appears to be wandering in laboratory areas and hallways and ask if you can help direct them.

05

Secure your highly hazardous materials. Consider using a log to sign hazardous materials in and out of secure storage and be sure to take a periodic inventory of all highly hazardous chemicals, biological agents/toxins, and controlled substances (this is required for use of radioactive materials). This could be as simple as frequently looking at your chemical containers to be sure that none are missing. Report any missing inventory to KAUST security immediately.

06

Know what materials are being ordered and brought into the laboratory area. Visually screen packages before bringing them into your lab. Packages containing potentially infectious materials should be opened in a biological safety cabinet or other appropriate containment device. Know what materials are being removed from the laboratory area and consider tracking the use and disposal of hazardous materials.

07

Pay special attention to the following:Open labs Unrestricted access to toxic chemicals Unlocked support roomsToxic gas security Unsecured biological materials and waste Access to controlled substances

Risk Assessment

Evaluation and assessment of risk is an integral step in designing an experimental protocol. Not only does a thorough risk assessment allow researchers to systematically identify and control hazards, but also improves science through better planning and understanding of the research question and variables.
KAUST has developed a template Lab Activity Risk Analysis (LARA); this tool provides a framework for risk assessment that maps onto the scientific method, melding with the process researchers already use to answer scientific questions. LARA
Contact HSE@kaust.edu.sa with any questions or to request support in conducting a risk assessment.

What are the steps for risk assessment?

The Risk Assessment Tool uses a four-part framework that can be used for an experiment, analytical process, or series of tasks:

Research

Determine the scope of your work, beginning with your research objective. What scientific question(s) are you trying to answer or problem(s) are you trying to solve? Conduct a broad review of the literature. Consider querying other disciplines. Talk with others who have done similar work.

Organize

Outline your procedure/tasks. This may include a deeper dive into specific topics in the literature. Determine hazards associated with each step/task and the control measures for reducing risk. HSE can help with more detailed guidance on how to control certain hazards.

Question

What assumptions did you use? Question the importance of each step. Seek advice from others to challenge your thinking. Ask yourself “what could go wrong?” Assign a risk rating (revising steps or controls particularly if risk category is “high” or “unacceptable”). HSE can provide experimental design review to help with this process.

Evaluate

Implement a model, prototype, or trial run. Can you perform a dry run to familiarize yourself with equipment and procedures? Can you test your experimental design at a smaller scale or with a less hazardous material? Determine if any design changes are needed. Run your experiment and monitor how your controls perform. Assess as you go and make changes as necessary.

FAQs

Who should do Risk Assessments?

​All researchers should conduct a risk assessment prior to conducting an experiment for the first time. When repeating an experiment/process, researchers may refer to a previous risk assessment and update the “Evaluate” section with the findings. The risk assessment process involves rating the risk of the experiment, from low to unacceptable risk. Consult with your PI/supervisor and HSE if your risk rating is “high” or “unacceptable” to redesign the experiment and/or implement additional controls to reduce risk.

What is the PI/LSR's role?

PIs and LSR should review risk assessments conducted by lab personnel/researchers. When personnel identify a “high” or “unacceptable” risk, PIs must work with them to redesign experiments or implement controls to reduce risk. If the risk rating remains “high” or “unacceptable” after redesign, consult HSE to provide guidance to control hazards.
In addition to review of risk assessments, PIs are also encouraged to use the risk assessment framework during group meetings to discuss planned or completed experiments.

When is a Risk Assessment used versus a Standard Operating Procedure (SOP)?

Risk Assessments and Standard Operating Procedures (SOPs) are complementary tools. An SOP is typically written for repeated operations, equipment use, or required maintenance. SOPs may also be required for high-hazard chemicals and operations (e.g. work involving particularly hazardous substances, hihly reactive chemicals, and other high risk research procedures).


A Risk Assessment is well-suited to novel operations in which the researcher is designing and planning an experiment. However, the Risk Assessment Tool can also be helpful in understanding risk when preparing for procedures that have an established SOP, varying parameters (e.g. scale, reagents, conditions), or in preparing to write new SOPs.
