- 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.

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. Locate nearest fire alarm box Clear exits Store

- 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 buildingdo 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

- 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 leavestuff 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. Check closed doors before
opening; if hot, choose another route. Crawl if there is smoke.
