Eyewash and Safety Shower 24

Use of Eyewash Remove contact lenses if possible. Forcibly hold eyes open in eyewash. Have someone else turn on eyewash and call emergency response. Irrigation should last AT LEAST 15 MINUTES, even if emergency crews arrive more quickly. Remove contact lenses if possible. Forcibly hold eyes open in eyewash.

Safe Handling of Chemicals Proper labeling of all materials. Minimize exposure to all chemicals No eating, drinking, or applying cosmetics in labs. Avoid mouth pipetting and inhalation. Clean up residue from counters, containers, and equipment daily! Wash your hands when leaving the lab. Proper labeling of all materials.

Example of Incompatible Chemical Storage Weak acid and weak base stored in same cabinet over period of time…….

Chemical Spills When in doubt, evacuate the area and notify instructor. Small spills---use Chemsorb to absorb and dispose as hazardous waste. Large spills (especially of fuming acids)— evacuate and call 911. When in doubt, evacuate the area and notify instructor. Small spills---use Chemsorb to absorb and dispose as hazardous waste.

43 Fire Prevention Guidelines

Fire Safety Tips Locate nearest fire alarm box Clear exits Store flammable/combustible materials in appropriate containers away from heat and spark sources. Never leave open flame unattended. Regularly check electrical cords/switches. No extension cords long-term.

In the Event of a Fire Activate pull station. If there is time, turn off open flames, turn off instrumentation, and stabilize experiments. Pull down fume hood sashes. Close the door. Alert others. Exit the building—do not use elevators!! Call 911 from another building or from a cell phone outside. Identify as being at NC State. Assemble at meeting area and account for everyone Do not re-enter the building until cleared by first responders. Activate pull station.

Surviving a Building Fire Never use an elevator. Check closed doors before opening; if hot, choose another route. Crawl if there is smoke. Take short breaths, freshest air is near the door. If you cannot leave—stuff towel, clothing, etc., under door, over vents to restrict smoke and fumes. Open window if possible. Call 911 and give your exact location. Use a towel, sheet, pillowcase, or clothing to hang out the window to mark your location for first responders to see. Never use an elevator.
