prevent absorption. Consideration should be given to the use of an intratracheal tube, to
prevent aspiration. Irregular heart beat may occur, use of adrenalin is not advisable.
Individuals intoxicated by the product should be hospitalized immediately, with acute and
continuing attention to neurological and cardiopulmonary function. Positive pressure
ventilation may be necessary. After the initial episode, individuals should be monitored
for changes in blood variables and the delayed appearance of pulmonary edema and
chemical pneumonitis. Such patients should be monitored for several days or weeks for
delayed effects, including bone marrow toxicity, hepatic and renal impairment.
Individuals with chronic pulmonary disease will be more seriously impaired, and recovery
from inhalation exposure may be complicated. In case of skin injection, prompt
debridement of the wound is necessary to minimize necrosis and tissue loss.

exposed to a source of ignition, can burn in the open or be explosive in confined spaces.
instructions
Mists or sprays may be flammable at temperatures below the normal flash point. Dry
chemical, halon carbon dioxide are the preferred extinguishing media. Foam and water
fog are effective but can cause frothing. Big fires, such as tank fires, should be fought
with caution. If the burning liquid is 200F or hotter, the use of water, water spray, or
foam can cause frothing and even sudden boilover of the tank, endangering the lives of
personnel such as firefighters. If possible, pump the contents from the tank and keep
adjoining structures cool with water. Water can be used to cool fire-exposed containers,
structures and to protect personnel. If a leak or spill has not ignited, ventilate area and
use water spray to disperse gas or vapor and to protect personnel attempting to stop a
leak. Use water to flush spills away from sources of ignition. Do not flush down public
sewers.
Flammable liquid and vapor. Vapor may cause flash fire. Vapors may accumulate in
low or confined areas or travel a considerable distance to a source of ignition and flash
back. Runoff to sewer may create fire or explosion hazard.

and sewers. If facility or operation has an "oil or hazardous substance contingency plan",
activate its procedures. Stay upwind and away from spill. Wear appropriate protective
equipment including respiratory protection as conditions warrant. Do not enter or stay in
area unless monitoring indicates that it is safe to do so. Isolate hazard area and restrict
entry to emergency crew. Extremely flammable. Review Fire and Explosion Hazard
Data before proceeding with clean up. Keep all sources of ignition (flames, smoking,
flares, etc.) and hot surfaces away from release. Contain spill in smallest possible area.
Recover as much product as possible (e.g., by vacuuming). Stop leak if it can be done
without risk. Use water spray to disperse vapors. Spilled material may be absorbed by
an appropriate absorbent, and then handled in accordance with environmental
regulations. Prevent spilled material from entering sewers, storm drains, other
unauthorized treatment or drainage systems and natural waterways. Contact fire
authorities and appropriate federal, state and local agencies. If spill of any amount is
made into or upon navigable waters, the contiguous zone, or adjoining shorelines,
contact the National Response Center at 800-424- 8802. For highway or railway spills,
contact Chemtrec at 800-424-9300.
: If emergency personnel are unavailable, contain spilled material. For small spills, add

absorbent (soil may be used in the absence of other suitable materials) and use a non-
sparking or explosion-proof means to transfer material to a sealable, appropriate
container for disposal. For large spills, dike spilled material or otherwise contain it to
ensure runoff does not reach a waterway. Place spilled material in an appropriate
container for disposal.

sparks and flame. To avoid fire or explosion, dissipate static electricity during transfer by
grounding and bonding containers and equipment before transferring material. Use
explosion-proof electrical (ventilating, lighting and material handling) equipment. To
prevent ingestion and exposure - Do not siphon by mouth to transfer product between
containers. Use good personal hygiene practices. After handling this product, wash
hands before eating, drinking, or using toilet facilities.
