Personal Protective Equipment  
• Gloves   
• Safety glasses or splash goggles  
• Lab coat  
Nitrile gloves are an excellent barrier to atrazine.  
Change gloves immediately if a spill on gloves is   
observed. Wash hands after use.  
OTHER SAFETY INFORMATION  
Transportation Follow guidance given in the laboratory safety manual   
for transport of chemicals.  
Storage  
• Can be stored with other dry chemicals but in   
a dedicated section for toxic chemicals.  
• Keep tightly sealed   
Incompatible materials include:  
Strong acids, strong bases, strong oxidizing agents  
Spill/Accident Procedures  
For all spills:  
• Wear two pairs of nitrile gloves  
• Turn off sources of ignition (if safe)  
• Evacuate the immediate area  
Exposure:  
• If anyone exposed requires emergency   
medical attention, dial 911 (or 9-911 from   
landline).  
• Follow procedures outlined in laboratory   
safety manual.  
Small spills (less than 2 kg): Small spills may be   
cleaned by sweeping up dry powder and placing them   
in a container. If the spill is a liquid, cover with   
absorbent material and then place the absorbent   
material container. Clean area with soap and water   
once spill is removed.  
Large spills (greater than 2 kg): If the spill is in a   
chemical fume hood, contact the EHS director (864-  
710-2933). If he cannot be reached (does not answer   
phone, do not leave voicemail), then call 911, pull the   
fire alarm and exit the building. If the spill is outside of   
a hood, then call 911, pull the fire alarm and exit the   
building.  
Waste Disposal Waste atrazine must be collected for disposal.  
Empty bottles of atrazine may be rinsed and thrown in   
the dumpster.
