Paraquat

CAS RN: 4685-14-7

Protective Equipment / Clothing

Wear appropriate personal protective equipment to prevent skin contact. /Paraquat dichloride/
Wear appropiate eye protection to prevent eye contact. /Paraquat dichloride/
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.) /Paraquat dichloride/
The following minimum (baseline) PPE /are required by the USEPA/ for all occupational uses of paraquat end-use products:Mixers and loaders must wear: long-sleeved shirt and long pants, chemical-resistant gloves, shoes plus socks, chemical-resistant apron, face shield. Although there is no direct evidence that occupational handlers have ever ingested a lethal amount of paraquat from a splash or spill, the requirement for a face shield for all mixers and loaders reflects the /USEPA's/ particular concern about accidental swallowing in case of a spill or splash back.
Early-entry personal protective equipment (PPE): The PPE required for early entry is: coveralls, chemical-resistant gloves, shoes plus socks,protective eyewear.
Applicators and other handlers (other than mixers and loaders) must wear: long-sleeved shirt and long pants, chemical-resistant gloves, shoes plus socks.
When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides (40 CFR 170.240(d)(4-6), the handler PPE requirements may be reduced or modified as specified in the WPS.
