In the lab, safe behavior and appropriate PPE are  key to preventing personal exposure to hazardous materials. However, in the event that your eyes  or skin are exposed to hazardous chemicals or biohazardous materials, you should know what to  do. The purpose of this video is to demonstrate: how to use the safety eyewash station in  the event a material gets in your eyes, how to use a sink to rinse skin in  the event of a small skin exposure, and how to use the safety shower in  the event of a l
arge body exposure. Note that safety showers and eye wash stations  may look different at different campuses. You will see the equipment at your campus  during your Lab Safety Site Orientation. For true splash protection, only wear safety  goggles marked with the ANSI Z87+D3 designation, and wear goggles for the  entire time you are in the lab. Also, never touch your eyes while in the lab, as  your hands may be contaminated with a chemical. In the event that a chemical or hazardous liquid  does
get into your eyes, proceed immediately to the nearest eye wash station. It may be  difficult to see, so ask someone for help. Most eye wash stations have a lever  or handle to activate the water flow. Activate the water flow and place  your eyes directly into the water. You will need to hold your eyelids open, and  let the water wash your eyes for 15 minutes. It will not be comfortable to hold your eyes  open in the water for that long, but it is necessary to flush out the hazardous material, 
and it is well worth it to save your eyes! Have someone call security and check the SDS  for the material that was splashed in your eyes. Ensure that security documents the  incident with an Incident Report afterward. Consult a doctor if any irritation or ill  effects remain after 15 minutes of flushing. It is possible that you will spill a chemical  or hazardous material on your skin in the lab, especially if you are not wearing  protective sleeves or a lab coat. Depending on your campus or cou
rse,  lab coats may or may not be required. In the event of a small splash to your  arms or hands, you should remove your lab coat and go to the nearest sink to flush  your skin with water for fifteen minutes. Have someone check the SDS to determine  if any further action is required based on the chemical or hazardous material, and  always alert security to any exposure of a chemical or hazardous material to document  the incident with an Incident Report. If a chemical spill occurs over  a large
portion of the body, it will be necessary to use the safety shower. Move immediately to the shower and  begin removing contaminated clothing. If you are in the lab with someone who  needs to use the shower, assist them. Let the water flow for 15 minutes to fully rinse  your skin to remove the hazardous material. Now is not a time for modesty, you will want to  remove all the hazardous material from your body. Have someone check the SDS to determine if  any further action is required based on th
e chemical or hazardous material, and alert  Security that an exposure has occurred. If you are an instructor and a student needs  to use the shower, ask the rest of the class to turn off their equipment and evacuate the lab. Taking appropriate safety measures such as safe lab behavior and wearing appropriate PPE goes  a long way to prevent exposure to hazardous materials. In the event exposure does occur, you  should be prepared to rinse the affected area immediately using appropriate safety eq
uipment. Be sure to check the Safety Data Sheet, or SDS, of the chemical involved in the exposure  to see if additional care is needed. Also contact Security to complete  an incident response form, and to receive assistance if needed. If you have any questions regarding the use of safety shower and eyewash equipment, please reach  out to your campus’ Lab Manager or Lab Supervisor.
