What is risk assessment? Risk assessment - process of evaluating the potential hazards and risks that may be associated with an activity Hazard - inherent property of a material or situation that has a potential for harm and cannot be altered Can be chemical, biological, radiological, physical Examples: Hexane is hazardous because it is flammable. Risk - the probability that a hazard will result in adverse consequence, and the severity of that consequence Can be applied to property, materials, and people Example: 10 mL vs. 100 mL hydrochloric acid (same hazard but different risk associated when working with each volume) Hazard is an inherent property that can t be changed, but risk can be minimized!

How to perform a risk assessment? RAMP Recognize the hazards (hazard identification) Identify materials, instruments, experimental conditions and techniques, and anything that can create a hazard Slide adapted from Brain Meschewski (DRS) and DRS website page on SOPs
Recognizing chemical hazards Chemical hazards fall into three main groups: physical, health, and environmental hazards Initial inspection of chemical containers shows major hazards pictograms Oxidizer, increases likelihood of/increases fire Severe explosion and fire hazard Pressurized gas https://www.pure-chemical.com/blog/hazard-symbols/
Recognizing chemical hazards More comprehensive and detailed hazard information found in Safety Data Sheets (SDS) 1 = most severe hazard 4 = least severe hazard PubChem https://www.sigmaaldrich.com/US/en/sds/sigald/179124 https://pubchem.ncbi.nlm.nih.gov/compound/180#section=Safe-Storage https://www.osha.gov/sites/default/files/publications/OSHA3678.pdf
Recognizing physical and operational hazards Physical hazard inherent property of an object to cause physical harm Examples: Sharp broken glass, hot heating element, laser damage to eyes Operational hazards potential for harm caused by equipment failures, human errors, or deviations from planned parameters Example: Temperature of furnace overshoots setpoint Read hazard descriptions in instrument/equipment manuals and consult researchers who are experienced with the specific equipment or technique.
How to perform a risk assessment? RAMP Recognize the hazards (hazard identification) Identify materials, instruments, experimental conditions and techniques, and anything that can create a hazard Assess the risks of the hazards Determine the risks posed by hazards during an experiment Before performing an experiment, think about the risks you may be exposed to What-If analysis Risk (R) = Probability of occurrence (P) x Severity of Consequence (S) Slide adapted from Brain Meschewski (DRS) and DRS website page on SOPs
Risk assessment approach P S No effect Minor Light Heavy Catastrophic Unlikely Remote Occasional Repeated Frequent For each hazard determine where it would fall on the graph Implement controls to move your procedure into green away from yellow and red Slide adapted from Brain Meschewski (DRS) and DRS website page on SOPs

RAMP Recognize the hazards (hazard identification) Identify materials, instruments, experimental conditions and techniques, and anything that can create a hazard Assess the risks of the hazards Determine the risks posed by hazards during an experiment Before performing an experiment, think about the risks you may be exposed to What-If analysis Risk (R) = Probability of occurrence (P) x Severity of Consequence (S) Minimize the risk of the hazards Hierarchy of controls Slide adapted from Brain Meschewski (DRS) and DRS website page on SOPs
Hierarchy of Controls Start at the top and work your way down Not all will be effective for each experiment or situation Slide adapted from Brain Meschewski (DRS) and DRS website page on SOPs

Preparing for emergencies What is the worst that can happen? Prepare plans to safely handle possible scenarios: Fire in lab What to know: Location of fire extinguishers and how to use them, who to alert, when to evacuate Chemical exposure What to know: Signs and symptoms of exposure to chemical being used, what to do in case of exposure, who to alert Always practice situational awareness! Envision what the safe laboratory scene would look like and imagine possible warning signs of danger that may appear. Slide adapted from Brain Meschewski (DRS) and DRS website page on SOPs
Lets practice applying RAMP Acid digestion protocol Slide adapted from Risk Management in the Research Lab: RAMP Workshop by the ACS Division of Chemical Health and Safety
New Slack Channel for LSOs Working with a new hazard and seeking safety-related advice from other experienced LSOs? Have safety-related advice to share with other LSOs? Join the LSOs Slack Channel! https://join.slack.com/t/uiucchemistrylsos/shared_invite/zt-2d4ejfwcl- GK_WKPUM~HxEr05PS~TZvQ Disclaimer: This form of communication does not take the place of an official DRS or SCS Facilities consultation. It is simply a method of sharing resources and perspectives and keeping the LSO community connected. 18
Thank you for coming! Please forward LSO meeting recap email/slides to your group! We can stay for a few minutes if there are further questions. 19
