Hello CERID,
Happy (almost) Summer!

New Regulations for Chemical Waste Containers

Washington State Department of Ecology has updated hazardous waste labeling regulations. Here's what's new:

  • If the waste is in its original container, label still legible, and the container is four liters or smaller, you do not need to add a hazardous waste label.
  • If the waste is not in its original container and the container is four liters or smaller, you must fill out a UW Hazardous Waste Label with full percentages of all constituents and check the primary hazard.
  • If the waste is in a container larger than four liters, regardless of whether or not it is the original container, you must fill out a UW Hazardous Waste Label and apply a second label visible at 25 feet with the words "HAZARDOUS WASTE" and the primary hazard.

Safety in the Summer Sun

The weather is getting warmer and the days are getting longer, which means more exposure to the sun's radiation. Be sure to apply sunscreen on a regular basis (even on cloudy days).

  • Apply sunscreen 30 minutes prior to going out and reapply every 2 hours or after sweating heavily or swimming.
  • Heading to a beach with reefs? Concerned about the environmental impact? Not to worry! Choose "non-nanotized" zinc oxide or titanium dioxide sunscreens. The sunscreens with the most evidence of environmental harm are oxybenzone and octinoxate based.
  • Up to 80% of the sun's UV rays can pass through clouds. Still apply that sunscreen!
  • Don't forget to protect your eyes! Make sure your sunglasses provide 100% UV protection.
