Other Preventive Measures

Note to Physician: For all exposures administer atropine and 2-PAM as an antidote for acetylcholinesterase inhibition.
Avoid eye, skin, clothing contact. Do not breathe dust. Use with adequate ventilation. ... Wash thoroughly after handling.
If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing eye. Call a poison control center or doctor for further treatment advice. If on skin or clothing: Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Call a poison control center or doctor for further treatment advice. /De-Fend E-267/
Users should: wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet; remove clothing immediately if pesticide gets inside, then wash thoroughly an put on clean clothing; and remove personal protective equipment immediately after handling this product; wash the outside of gloves before removing; as soon as possible, wash thoroughly and change into clean clothing. /De-Fend E-267/
Maintain good ventilation at the site. No eating and smoking at the site. Wash daily all the garments.
Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark.... Do not contaminate water by cleaning equipment or disposal of wastes. /De-Fend E-267/
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit 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 such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. All contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
... A number of phosphate and thiophosphate esters are of limited thermal stability and undergo highly exothermic self-accelerating decomp reactions which may be further catalyzed by impurities. The hazards can be reduced by appropriate thermal control measures. An example is the substitution of hot water at 60 deg C for pressurized steam to melt a solid phosphate ester, which on adiabatic calorimetric examination was found to have a time to maximum decomp rate of 6 hr at 110 deg C but 11 hr at 100 deg C. The combined used of vapor phase pyrolysis to decomp various phosphorus esters, and of GLC and mass spectrometry to analyze the pyrolysis products, allowed a thermal degradation scheme to be developed for phosphorus esters ... /Phosphorus esters/
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. /Organophosphorus pesticides, liquid, NOS/
