Section 16 - Other information

Other precautions: 

Observe all necessary precautions for handling powders as fine powder may present dust 

explosion hazard. ACGIH threshold limit values (TLV) for particulate matter: inhalable 

particulate = 10 mg/m3 / respirable particulate = 3 mg/m3 OSHA permissible exposure limit 

(PEL) for particulate matter: Total dust = 15 mg/m3 / respirable fraction = 5 mg/m3. 

Handle with care. Organic dusts have the potential to be explosive with static spark or flame 

initiation. 

Label information:

WARNING!
