Skin, Eye, and Respiratory Irritations
Eye contact may cause injury. Contact with irritated skin, or a cut, or repeated contact with intact skin will cause severe irritation and may result in poisoning. Inhalation exposure may cause irritation, nosebleeds and may lead to poisoning.
Paraquat as a mist or aerosol is an irritant of ... mucous membranes and skin.
It is irritant to eyes.
Cleanup Methods
SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.
Avoid exposure by the use of appropriate protective clothing, gloves, and goggles or masks. Keep spectators away from leaking or spilled product and prevent smoking, and the use of naked flames, in the immediate vicinity ... Prevent liquid from spreading to other cargo, vegetation, or waterways by containing it with the most readily available barrier material, e.g., earth or sand. Absorb spilled liquid and cover contaminated areas with earth, lime, sand, or other absorbent material; sweep up and place in a secure container for subsequent safe disposal. Spillage: Avoid exposure by the use of appropriate protective clothing and face-shield. Empty any product remaining in damaged or leaking containers into a clean empty drum and label. Absorb spillage with lime, damp sawdust, sand, or earth and dispose of safely ... If spillage is large, contain it by building a barrier of earth or sandbags. Decontaminate empty, damaged, or leaking containers with a 10% sodium carbonate solution, added at the rate of at least 1 L per 20 L drum. Puncture or crush containers to prevent reuse.
If paraquat is spilled, ... ventilate area of spill. Collect spilled material in the most convenient and safe manner and deposit in sealed containers for reclamation. Liquid containing paraquat should be absorbed in vermiculite, dry sand, earth, or a similar material.

Fire Fighting Procedures
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. Poisonous gases are produced in fire. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. Containers may explode in fire. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position.
If involved in a fire, control with dry powder or alcohol-resistant foam ... Protective clothing and self-contained breathing apparatus should be worn, to avoid skin contamination and the breathing of toxic fumes. Confine the use of water spray to the cooling of unaffected stock, thus avoiding the accumulation of polluted run-off from the site.

Reactivities and Incompatibilities
Incompatibilities: Strong oxidizers, alkylaryl-sulfonate wetting agents [Note: Corrosive to metals. Decomposes in presence of ultraviolet light.] /Paraquat dichloride/
Strong bases
Other Preventative Measures
SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
SRP: Contaminated protective clothing should be segregated in a manner that results in no direct personal contact by personnel who handle, dispose of, or clean the clothing. Quality assurance procedures to confirm the efficacy of the cleaning procedures should be implemented prior to the decontaminated protective clothing being returned for reuse by the workers. Contaminated clothing (including shoes/socks) should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
Entry Restrictions. For sole-active-ingredient end-use products that contain paraquat the product labeling must be revised to adopt the entry restrictions set forth in this section. Any conflicting entry restrictions on the current labeling must be removed. For multiple-active-ingredient end-use products that contain paraquat the entry restrictions set forth in this section must be compared to the entry restrictions on the current labeling and the more protective must be retained. A specific time period in hours or days is considered more protective than "sprays have dried" or "dusts have settled."
The /USEPA/ is establishing the following entry restrictions for non-Worker Protection Standard occupational uses of paraquat end-use products: Do not enter or allow others to enter the treated area until sprays have dried.
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. DO NOT USE AROUND HOMES, SCHOOLS, RECREATIONAL PARKS, GOLF COURSES, OR PLAYGROUNDS.
Users should wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet. Users should remove clothing immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. Users should remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.
The worker should immediately wash the skin when it becomes contaminated. /Paraquat dihloride/
Work clothing that becomes wet or significantly contaminated should be removed and replaced. /Paraquat dichloride/
For several good reasons, .... herbicides ... should be handled and applied only with full attention to safety measures that minimize personal contact. Many formulations contain adjuvants (stabilizers, penetrants, surfactants) that may have significant irritating and toxic effects. A number of premixed formulations contain two or more active ingredients; the companion pesticides may be more toxic than the principal herbicide. Good hygienic practice should not be disregarded just because a pesticide is reported to have a high LD50 in laboratory rodents.
Protective Equipment and 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.
Respirator Recommendations: Up to 1 mg/cu m. /Paraquat dichloride/ Assigned Protection Factor (APF) Respirator Recommendation APF = 10 Any air-purifying half-mask respirator with organic vapor cartridge(s) in combination with an N95, R95, or P95 filter. The following filters may also be used: N99, R99, P99, N100, R100, P100. Substance reported to cause eye irritation or damage; may require eye protection. APF = 25 Any powered, air-purifying respirator with an organic vapor cartridge in combination with a high-efficiency particulate filter. Substance reported to cause eye irritation or damage; may require eye protection. APF = 10 Any supplied-air respirator.

Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.
Paraquat is rapidly inactivated in soil. It is also inactivated by anionic surfactants. Therefore an effective and environmentally safe disposal method would be to mix the product with ordinary household detergent and bury the mixture in clay soil.
If incineration facilities are unavailable for a particular organic or metallo-organic pesticide (except organic mercury, lead, cadmium, and arsenic compounds), additional disposal methods include, soil injection, chemical degradation, burial (in a designated landfill), or well injection. However, persons considering the chemical degradation method should contact EPA's Regional Administrator ... prior to attempting disposal, while the well injection method should only be considered after all reasonable alternative measures have been explored and found to be less satisfactory in terms of environmental protection. If the above approved disposal methods are unavailable, temporary storage of organic and metallo-organic pesticides (except organic mercury, lead, cadmium and arsenic compounds), may be undertaken. /Organic or metallo-organic pesticide/
Group I Containers: Combustible containers from organic or metallo-organic pesticides (except organic mercury, lead, cadmium, or arsenic compounds) should be disposed of in pesticide incinerators or in specified landfill sites. /Organic or metallo-organic pesticides/
Group II Containers: Non-combustible containers from organic or metallo-organic pesticides (except organic mercury, lead, cadmium, or arsenic compounds) must first be triple-rinsed. Containers that are in good condition may be returned to the manufacturer or formulator of the pesticide product, or to a drum reconditioner for reuse with the same type of pesticide product, if such reuse is legal under Department of Transportation regulations (eg 49 CFR 173.28). Containers that are not to be reused should be punctured ... and transported to a scrap metal facility for recycling, disposal or burial in a designated landfill. /Organic or metallo-organic pesticides/
Waste containing paraquat should be burnt in a proper high temperature incinerator with effluent gas scrubbing. Where no incinerator is available, contaminated absorbents or surplus products should be decomposed by hydrolysis at pH 12 or above. A 5% sodium hydroxide (caustic soda) solution or saturated (7-10%) sodium carbonate (washing soda) solution can be used. Before disposal of the resultant waste, the material must be analysed to ensure that the active ingredient has been degraded to a safe level. Paraquat is rapidly inactivated by clay soil. If the above mentioned methods are not possible, it can be buried in an approved landfill. Never pour untreated waste or surplus products into public sewers or where there is any danger of run-off or seepage into streams, water-courses, open waterways, ditches, fields with drainage systems, or the catchment areas of boreholes, wells, springs, or ponds.
