Laboratories, shops and maker spaces where hazardous materials are used or stored are required to post an up-to-date sign at the entrance. The sign is intended to alert emergency responders and visitors of potential hazards and precautions for entry.
- EH&S installs the sign holder and posts the initial sign. Occupants update signs as needed using the tool available on the MyChem menu.
- You must have an account in the MyChem chemical inventory system to create or edit a sign based on the chemical inventory in your laboratory, shop or maker space.
- The National Fire Association (NFPA) has developed a color-coded number system called NFPA 704. The system uses a color-coded diamond with four quadrants in which numbers are used to signal the degree of health hazard (blue), flammability hazard (red), and instability hazard (yellow).
For more information on how to understand the fire triangle, refer to the UW Caution sign for hazards webpage.
Compressed gas is a generic term used for describing gases stored in a pressurized tank.
If you experience a compressed gas leak:
- Leave the area immediately and get to a source of fresh air.
- Contact Campus Security at 425-352-5359 or call 911.
- Complete a report in the Online Accident Reporting System.
Emergency washing equipment
Eye washes are required in areas where any of the following agents are used: corrosives; strong irritants; or toxic chemicals of concern.
- Showers are co-located with eyewash stations outside of all necessary Labs.
- If any equipment is in malfunctioning condition, or there is visible damage, report it to your supervisor immediately.
What you need to know:
- Where your safety equipment is and how to use it
- Weekly flushing for eyewashes and annual for showers
- Refer to section four (4) of the Laboratory Safety Manual for information
Safety manuals contain vital information to maintain the health and safety of those working with potentially hazardous materials or equipment. Any UW faculty, staff or student working with hazardous chemicals, biological agents, radioactive materials, lasers should follow the rules and guidance provided in the appropriate safety manual(s).
