Eyewash and Safety Shower

24Use of EyewashRemove 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.

2526Safety ShowersUsed in the event that significant amounts of caustic, toxic, or otherwise hazardous materials are spilled on yourself or others.Get under the showerPull the handle downIf necessary, remove contaminated clothing or shoes

Generally located in the hallways outside of laboratories.SAFETY ALARMSFire AlarmOxygen Sensor (NMR Room)Fume Hood27E-STOP

29E-StopsTypically located near the door.Shut off power to electrical wall outletsUseful in fire fighting or electrocutionDo not cut power to the lightingDo not cut power to high voltage equipment

NO FOOD OR DRINK!!!30

Including empty wrappers and cups!!! This is an OSHA violation!

34Incompatible ChemicalsMany explosions, fires, and asphyxiations are caused by the accidental combination of potentially dangerous substances.

Some common incompatibles include:Alkali Metals(Ca, K, Na)WaterCarbon dioxideCarbon tetrachlorideOther chlorinated hydrocarbonsAcetic AcidChromic acidNitric acidEthylene glycolPerchloric acidPeroxidesPermanganatesAcetoneSulfuric acidNitric acidHydrogen PeroxideCopperChromiumIronFlammable FluidsCombustible MaterialsNitromethaneAnilineNitric AcidAcetic AcidChromic AcidCarbonHydrogen SulfideFlammable materials

Example of Incompatible Chemical Storage

Weak acid and weak base stored in same cabinet over period of time.Chemical SpillsWhen 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.

43Fire Prevention Guidelines

Fire Safety TipsLocate nearest fire alarm boxClear exitsStore 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.

44In the Event of a FireActivate 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 everyoneDo not re-enter the building until cleared by first responders.45Surviving a Building FireNever 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.
