Chemical Identification/RIDS Chemical Name: PARAQUAT DICHLORIDE Regulatory Name: PARAQUAT DICHLORIDE NFPA Codes F: NFPA Codes H: Formula: C12H14N2.2CI DOT: POISON UN Num: 2781 Sec 112R: ❑ EHS: CERCLA: ❑ CAS: 1910-42-5 NFPA Codes R: CAATQ: 313: EHSTPQ: 10/10000 RCRA: RQ: 10 CHRIS: STCC: NFPA Codes S: General Description Colorless to yellow crystalline solid. Used as a contact herbicide and desiccant. (EPA, 1998) Fire Hazard Avoid strong oxidizers. (EPA, 1998) Fire Fighting This material is a bipyridilium compound. Procedures for bipyridilium pesticides are as follows. Small fires: dry chemical, carbon dioxide, water spray, or foam. Large fires: water spray, fog, or foam. Move container from fire area if you can do so without risk. Fight fire from maximum distance. Dike fire control water for later disposal; do not scatter the material. (EPA, 1998) Protective Clothing Skin: Wear appropriate personal protective clothing to prevent skin contact. Eyes: Wear appropriate eye protection to prevent eye contact. Wash skin: The worker should immediately'wash the skin when it becomes contaminated. Remove: Work clothing that becomes wet or significantly contaminated should be removed and replaced. Change: No recommendation is made specifying the need for the worker to change clothing after the work shift. Provide: Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.] (NIOSH, 2003) MATERIAL RATINGS BARRICADE > 3 hrs[limited data] NAT RUB > 3 hrs[limited data] NAT RUB+NEOP > 3 hrs[limited data] NAT RUB+NEOP+NBR < 1 hr[limited data] NITRILE > 3 hrs[limited data] PTFE TEFLON > 3 hrs[limited data] RESPONDER > 3 hrs[limited data] SARANEX23P > 3 hrs[limited data] These protective clothing recommendations are based on experimental data for another chemical with similar chemical properties and structure. Because material recommendations for chemicals in the same classification will generally, but not always, be appropriate, use caution when following these recommendations. (NOAA, 1991) Non -Fire Response (Non -Specific -- Bipyridilium Pesticide) Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Ventilate closed spaces before entering them. Remove and isolate contaminated clothing at the site. If water pollution occurs, notify appropriate authorities. Do not touch spilled material; stop leak if you can do so without risk. Use water spray to reduce vapors. Small spills: absorb with sand or other noncombustible absorbent material and place into containers for later disposal. Small dry spills: with clean shovel place material into clean, dry container and cover; move containers from spill area. 6/12/2007 Printed from CAMEO Page 1
