If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use "alcohol" foam, carbon dioxide or dry chemical. /Organophosphorus pesticides, liquid, NOS/|If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use "alcohol" foam, carbon dioxide or dry chemical. /Organophosphorus pesticides, solid, NOS/

DO NOT GET ON SKIN, IN EYES, OR ON CLOTHING. IN CASE OF CONTACT, WASH THOROUGHLY WITH LARGE AMT OF SOAP & WATER.|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. Use water spray to knock-down vapors. /Organophosphorus pesticides, liquid, NOS/|Personnel protection: Keep upwind. Wear appropriate chemical protective gloves, boots and goggles. Do not handle broken packages unless wearing appropriate personal protective equipment. Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. /Organophosphorus pesticides, liquid, NOS/|Special aircraft should preferably be used for spraying or dusting toxic organophosphorus pesticides. ... aerial spraying or dusting gives rise to clouds which spread over larger surfaces than clouds produced by ground application. Aerial spraying should therefore be carried out on windless days only. Residential areas, water supply sources, etc must be avoided. ... When aircraft approaches, signalmen /guiding the aircraft/ should leave the windward side. ... The local population should be informed about the site & time of aerial pesticide treatment. Access of unauthorized persons & especially children to the area to be treated must be ... forbidden. Warning signs should be placed at the limits of the area. Ground spraying must be carried out with compressed-air spraying equipment towed by tractors with closed cabs. /Organophosphorus pesticides/|For more Preventive Measures (Complete) data for BOMYL (6 total), please visit the HSDB record page.

Contraindications for work with /organophosphorus pesticides/ are organic diseases of the central nervous system, mental disorders & epilepsy, pronounced endocrine & vegetative disorders, pulmonary tuberculosis, bronchial asthma, chronic respiratory diseases, cardiovascular diseases & circulatory disorders, gastrointestinal diseases (peptic ulcer), gastroenterocolitis, diseases of liver & kidneys, eye diseases (chronic conjunctivitis & keratitis). The blood cholinesterase activity must be determined before work starts. In the event of prolonged work periods, this activity should be determined at intervals of 3-4 days. Persons exhibiting a fall in cholinesterase activity of 25% or more must be transferred to other work where they are not exposed to organophosphorus pesticides until this activity is completely restored. Persons with initial signs of indisposition should cease work with pesticides. /Organophosphorus pesticides/|Persons with a history of reduced pulmonary function, convulsive disorders, or recent exposure to anticholinesterase agents would be expected to be at increased risk from exposure.

1. INSURE THAT A CLEAR AIRWAY EXISTS BY ASPIRATION OF SECRETIONS IF NECESSARY. ADMIN OXYGEN BY MECHANICALLY ASSISTED PULMONARY VENTILATION IF RESPIRATION IS DEPRESSED. IMPROVE TISSUE OXYGENATION AS MUCH AS POSSIBLE BEFORE ADMIN ATROPINE TO MINIMIZE RISK OF VENTRICULAR FIBRILLATION. IN SEVERE POISONINGS, IT MAY BE NECESSARY TO SUPPORT PULMONARY VENTILATION MECHANICALLY FOR SEVERAL DAYS. 2. ADMIN ATROPINE SULFATE IV, OR IM IF IV INJECTION IS NOT POSSIBLE. ... IN MODERATELY SEVERE POISONING: ADULT DOSAGE AND CHILDREN OVER 12 YR: 0.4-2.0 MG REPEATED EVERY 15 MIN UNTIL ATROPINIZATION IS ACHIEVED. MAINTAIN ATROPINIZATION WITH REPEATED DOSAGE OF 0.02-0.05 MG/KG BODY WEIGHT. /ORGANOPHOSPHATE PESTICIDES/|2. SEVERELY POISONED INDIVIDUALS MAY EXHIBIT REMARKABLE TOLERANCE TO ATROPINE; TWO OR MORE TIMES THE DOSAGES SUGGESTED ABOVE MAY BE NEEDED. THE DOSE OF ATROPINE MAY BE INCREASED AND THE DOSING INTERVAL DECREASED AS NEEDED TO CONTROL SYMPTOMS. CONTINUOUS INTRAVENOUS INFUSION OF ATROPINE MAY BE NECESSARY WHEN ATROPINE REQUIREMENTS ARE MASSIVE. REVERSAL OF MUSCARINIC SYMPTOMS AND SIGNS, NOT AN ARBITRARY DOSE LIMIT, IS THE DESIRED END-POINT. PRESERVATIVE-FREE ATROPINE PRODUCTS SHOULD BE USED WHENEVER POSSIBLE. NOTE: PERSONS NOT POISONED OR ONLY SLIGHTLY POISONED BY ORGANOPHOSPHATES MAY DEVELOP SIGNS OF ATROPINE TOXICITY FROM SUCH LARGE DOSES. FEVER, MUSCLE FIBRILLATIONS, AND DELIRIUM ARE THE MAIN SIGNS OF ATROPINE TOXICITY. IF THESE APPEAR WHILE THE PATIENT IS FULLY ATROPINIZED, ATROPINE ADMINISTRATION SHOULD BE DISCONTINUED, AT LEAST TEMPORARILY, WHILE THE SEVERITY OF POISONING IS REEVALUATED. /ORGANOPHOSPHATE PESTICIDES/|3.
