Safety at MSE

General Health & Safety Guidelines for the Beginners at MSE department:
1) Discuss with your PI/Lab Supervisor/Course Instructor and your group’s safety officer or TA all the necessary safety training modules that you need to complete before starting to work in the laboratory. Completing the initial online Laboratory Safety Fundamental Concepts (LSFC) training and subsequently annual refreshers as well as reading up to date Chemical Hygiene Plan (CHP) is absolutely mandatory for everybody at the MSE department working in the laboratory (or even just entering laboratory spaces) including visitors, summer students and all the undergraduate students taking any of the MSE laboratory classes (90L, 110L, 111, 121L, 131L, 141L, 161L) and MSE199. Additional courses may be required depending on the nature of your work e.g. biosafety, laser safety, etc. Discuss with your PI/Course Instructor and/or your safety officer/TA what is needed. You can register for safety courses, take the initial LSFC and annual refreshers and read current CHP via UCLA Worksafe using your UCLA login.
Note: Pay attention to taking LSFC refreshers annually and confirm that you have read and understood CHP whenever the new version is released! Always make sure that your training is up-to-date on Worksafe (under the section ‘transcripts’). If your training is not up-to-date, then all you need to do is to take an annual online refresher.

To complete online your Laboratory Safety Fundamental Concepts (LSFC) requirement, please do the following:

  1. Navigate to EH&S’ Online Learning Center at
  2. Sign in using your UCLA Logon/Password
  3. Navigate to COURSE CATALOG from the left-hand menu
  4. Select Environment, Health and Safety – Online Training folder
  5. Click on LAUNCH next to the UCLA Laboratory Safety Fundamentals course.

Important information for visitors and summer students:  If you do not have your UCLA logon, you need to create one first at  before you register for the LSFC training at .

2) Become familiar with EH&S website which contains important information and resources related to health and safety at UCLA.
3) Always wear necessary PPE when conducting experiments. To enter any lab space even if you do not perform any experiments always remember to wear full length pants and closed toes shoes (make sure your legs and feet are fully covered e.g. ballet flats without socks are not allowed). This is an absolute minimum to enter any lab space!
4) Complete site safety orientation training and complete site safety orientation checklist for the lab(s) that you are using. These can be given by your lab safety officer. Become familiar with emergency procedures, responses, injury treatment/reporting.
5) In case of emergency call 911 (if you are calling from campus phone-landline) or 310- 825-1491 (if your call is from a cell phone). Save 310- 825-1491 number on your cell phone as if emergency occurs and you dial 911 from your cell phone it will go to the main city dispatch (LAPD) instead of UCPD so the response will be delayed.
6) Before working with any chemicals become familiar with their nature! Read necessary SDS and safety precautions. Discuss with your PI and/or safety officer if there are any particular safety measures that need to be taken into consideration. When working with particularly hazardous substances (PHS) for example carcinogens, reproductive or acute toxins, you will need to read/understand and sign Standard Operating Procedure (SOP) for these substances. Always follow Standard Operating Procedures (SOP’s) or Job Safety Assessments (JSA). Do not ever bypass of modify them unless recommended by the UCLA Environmental Health and Safety (EH&S)!
7) When not sure always ask either your PI/faculty, safety officer, or UCLA Environmental Health and Safety officer (EH&S).
8) Learn how to properly store, label, handle and dispose your chemicals. Follow EH&S guidelines and discuss with your safety officer what is proper. Find out if you will need to follow particular Standard Operating Procedure (SOP). Same rule applies to the equipment in the lab.
9) When removing old chemical, bringing in new chemical inform your safety officer as the chemical inventory in your lab needs to be constantly updated and necessary SOP’s (if needed) in place.
10) Be aware of your surroundings. Discuss with your PI and colleagues what other experiments (except your own) are being conducted in the lab area and if there are any safety precautions that you should be aware of. Make sure others in the lab are also familiar with what you are doing so they can always stay safe.
11) Always label everything properly (even DI water!).
12) Never bring into or consume any food/drinks in the lab. If you use food products for experiments e.g. vinegar or baking soda, etc. label them : ‘Research purposes only, not for human consumption’.
13) Reduce/eliminate working out of hours (late evenings, nights, holidays, weekends) and if working out of hours do not work alone and make sure you have a ‘buddy system’ in place. Do not conduct any dangerous/risky experiments out of hours or when you feel tired/distracted. Remember majority of the accidents happen out of hours!
14) Do not ever obstruct access to the emergency showers, eye wash stations or electrical panels e.g. by placing in front of them trash bins, cardboard boxes or bags.
15) Keep lab doors closed to maintain negative pressure and avoid fire hazards (fire from spreading out from room to room). Never leave laboratory open when it is unattended to prevent strangers from coming in and interacting with chemicals or equipment.
