General Description
A clear colorless gas with a strong odor. Shipped as a liquid under its own vapor pressure.Density(liquid)6
lb_/gal. Contact with the unconfined liquid can cause frostbite. Gas generally regarded as nonflammable but
does burn within certain vapor concentration limits and with strong ignition.Fire hazard increases in the
presence of oil or other combustible materials.Although gas is lighter than air,vapors from a leak initially hug
the ground.Prolonged exposure of containers to fire or heat may cause violent rupturing and rocketing.Long-
term inhalation of low concentrations of the vapors or short-term inhalation of high concentrations has adverse
health effects.Used as a fertilizer, as a refrigerant, and in the manufacture of other chemicals.
Rate of onset:Immediate
Persistence:Minutes
Odor threshold: 17 ppm
Source/use/other hazard:Explosives manufacture,pesticides; detergents industry.

Air&Water Reactions
Soluble in water with evolution of heat. The amount of heat generated may be large;
Fire Hazard
Mixing of ammonia with several chemicals can cause severe fire hazards and/or explosions.Ammonia in
container may explode in heat of fire.Incompatible with many materials including silver and gold salts,
halogens,alkali metals,nitrogen trichloride,potassium chlorate,chromyl chloride,oxygen halides, acid vapors,
azides,ethylene oxide,picric acid and many other chemicals. Mixing with other chemicals and water.
Hazardous polymerization may not occur. (EPA, 1998)
Health Hazard
Vapors cause irritation of eyes and respiratory tract.Liquid will bum skin and eyes.Poisonous;may be fatal if
inhaled.Contact may cause burns to skin and eyes. Contact with liquid may cause frostbite. (EPA, 1998)
Reactivity Profile
AMMONIA is a base.Reacts exothermically with all acids.Violent reactions are possible.Readily combines
with silver oxide or mercury to form compounds that explode on contact with halogens.When in contact with
chlorates it forms explosive ammonium chlorate [Kirk-Othmer, 3rd ed.,Vol.2, 1978,p 470].Reacts violently
or produces explosive products with fluorine,chlorine,bromine and iodine and some of the interhalogen
compounds (bromine pentafluoride, chlorine trifluoride).Mixing of bleaching powder(hypochlorite solution)
with ammonia solutions produces toxic/explosive ammonia trichloride vapors.Undergoes potentially violent or
explosive reactions on contact with 1,2-dichloroethane(with liquid ammonia),boron halides,ethylene oxide
(polymerization),perchlorates or strong oxidants (chromyl chloride, chromium trioxide,chromic acid,nitric
acid,hydrogen peroxide,chlorates,fluorine,nitrogen oxide, liquid oxygen).Reacts with silver chloride, silver
oxide,silver nitrate or silver azide to form the explosive silver nitride.May react with some heavy metal
compounds (mercury, gold(III)chloride)to produce materials that may explode when dry_ [Bretherick,5th ed.,
1995,p. 1553].

surface.Do not get water inside container.Move container from fire area if you can do it without risk. Stay
away from ends of tanks. Cool containers that are exposed to flames with water from the side until well after
fire is out. Isolate area until gas has dispersed. (EPA, 1998)
Non-Fire Response
Excerpt from GUIDE 125 [Gases-Corrosive]:
Fully encapsulating,vapor protective clothing should be worn for spills and leaks with no fire. Do not touch or
walk through spilled material. Stop leak if you can do it without risk.If possible,turn leaking containers so that
gas escapes rather than liquid.Prevent entry into waterways, sewers,basements or confined areas.Do not direct
water at spill or source of leak.Use water spray to reduce vapors or divert vapor cloud drift.Avoid allowing
water runoff to contact spilled material.Isolate area until gas has dispersed. (ERG,2012)
Protective Clothing
For emergency situations, wear a positive pressure,pressure-demand,full facepiece self-contained breathing
apparatus(SOBA)or pressure-demand supplied air respirator with escape,SCBA and a fully-encapsulating,
chemical resistant suit. (EPA, 1998)

(DuPont,2013)
First Aid
Warning: Ammonia is extremely corrosive to the skin,eyes, and mucous membranes. Contact with the liquified
gas may cause frostbite. Caution is advised.
Signs and Symptoms of Acute Ammonia Exposure: Inhalation of ammonia may cause irritation and bums of
the respiratory tract, laryngitis,dyspnea(shortness of breath), stridor(high-pitched respirations),and chest pain.
Pulmonary edema and pneumonia may also result from inhalation. A pink frothy sputum, convulsions, and
coma are often seen following exposure to high concentrations.When ammonia is ingested, nausea and
vomiting may result; oral,esophageal, and stomach bums are common.If ammonia has contacted the eyes,
irritation,pain, conjunctivitis (red, inflamed eyes),lacrimation(tearing), and corneal erosion may occur.Loss
of vision is possible.Dermal exposure may result in severe bums and pain.
Emergency Life-Support Procedures:Acute exposure to ammonia may require decontamination and life
support for the victims.Emergency personnel should wear protective clothing appropriate to the type and
degree of contamination.Air-purifying or supplied-air respiratory equipment should also be worn,as necessary.
Inhalation Exposure:
1. Move victims to fresh air.Emergency personnel should avoid self-exposure to ammonia.
2.Evaluate vital signs including pulse and respiratory rate,and note any trauma. If no pulse is detected,provide
CPR. If not breathing,provide artificial respiration.If breathing is labored, administer oxygen or other
respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or
performance of other invasive procedures.
4. Transport to a health care facility.
Dermal/Eye Exposure:
1.Remove victims from exposure.Emergency personnel should avoid self-exposure to ammonia.
2.Evaluate vital signs including pulse and respiratory rate,and note any trauma. If no pulse is detected,provide
CPR. If not breathing,provide artificial respiration. If breathing is labored, administer oxygen or other
respiratory suppoi tWarning: Do not attempt to neutralize with an acid wash;excessive liberation of heat may
result.
3. If eye exposure has occurred, eyes must IMMEDIATELY be flushed with lukewarm water for at least 15
minutes.
4.Remove contaminated clothing as soon as possible.
5.Wash exposed skin areas THOROUGHLY with soap and water.

ENDOSULFAN is an organochlorine,cyclodiene derivative.It is also a sulfite ester. Halogenated aliphatic or
cyclic alkane compounds are moderately or very reactive.Halogenated organics generally become less reactive
as more of their hydrogen atoms are replaced with halogen atoms.As endosulfan is rather highly substituted it
may be resistant to reaction.However,materials in this group are incompatible with strong oxidizing and

reducing agents. Also,they may be incompatible with many amines,nitrides, azo/diazo compounds, alkali
metals, and epoxides.As an ester, it will hydrolyze to form sulfur dioxide and diol;reaction is more rapid under
basic conditions.

Response Recommendations
Isolation and Evacuation
Excerpt from GUIDE 151 [Substances-Toxic(Non-combustible)]:
As an immediate precautionary measure,isolate spill or leak area in all directions for at least 50 meters (150
feet)for liquids and at least 25 meters(75 feet)for solids.
SPILL: Increase,in the downwind direction, as necessary,the isolation distance shown above.
FIRE: If tank,rail car or tank track is involved in a fire,ISOLATE for 800 meters(1/2 mile) in all directions;
also, consider initial evacuation for 800 meters(1/2 mile)in all directions. (ERG, 2012)
Firefighting
Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind;keep out of low areas.
Ventilate closed spaces before entering them.Wear positive pressure breathing apparatus and special protective
clothing.Remove and isolate contaminated clothing at the site.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not bum or bums with
difficulty.)Use water in flooding quantities as fog. Use alcohol foam,carbon dioxide or dry chemical. (EPA,
1998)
Non-Fire Response
Excerpt from GUIDE 151 [Substances-Toxic(Non-combustible)]:
Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if
you can do it without risk.Prevent entry into waterways, sewers,basements or confined areas. Cover with
plastic sheet to prevent spreading.Absorb or cover with dry earth,sand or other non-combustible material and
transfer to containers.DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2012)
Protective Clothing
Skin:Wear appropriate personal protective clothing to prevent skin contact.

_v'VF%jX L L
Eyes: Wear appropriate eye protection to prevent eye contact.
Wash skin: The worker should immediately wash the skin when it becomes contaminated.
Remove:Work clothing that becomes wet or significantly contaminated should be,removed and replaced.
Change:Workers whose clothing may have become contaminated should change into uncontaminated clothing
before leaving the work premise.
Provide:Eyewash fountains should be provided in areas where there is any possibility that workers could be
exposed to the substance;this is irrespective of the recommendation involving the wearing of eye protection.
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.] (NIOSH, 2003)

Fire Hazard
Excerpt from GUIDE 157 [Substances -Toxic and/or Corrosive(Non-Combustible/Water-Sensitive)]:
Non-combustible, substance itself does not bum but may decompose upon heating to produce corrosive and/or
toxic fumes.For UN1796,UN1826,UN2031 at high concentrations and for UN2032,these may act as
oxidizers, also consult GUIDE 140. Vapors may accumulate in confined areas(basement,tanks,hopper/tank
cars etc.). Substance may react with water(some violently),releasing corrosive and/or toxic gases and runoff.
Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if
contaminated with water. (ERG, 2012)
Health Hazard
Excerpt from GUIDE 157 [Substances -Toxic and/or Corrosive(Non-Combustible/Water-Sensitive)]:
TOXIC; inhalation, ingestion or contact(skin,eyes)with vapors,dusts or substance may cause severe injury,
bums or death.Reaction with water or moist air may release toxic,corrosive or flammable gases.Reaction with
water may generate much heat that will increase the concentration of fumes in the air.Fire will produce
irritating,corrosive and/or toxic gases.Runoff from fire control or dilution water may be corrosive and/or toxic
and cause pollution. (ERG, 2012)
Reactivity Profile
HYDROFLUORIC ACID attacks glass and any other silica containing material. May react with common
metals (iron, steel)to generate flammable hydrogen gas if diluted below 65%.Reacts exothermically with
chemical bases (examples:amines, amides,inorganic-hydroxides). Can initiate polymerization in certain
alkenes. Reacts with cyanide salts and compounds to release gaseous hydrogen cyanide. May generate
flammable and/or toxic gases with dithiocarbamates,isocyanates,mercaptans,nitrides,nitriles, sulfides.
Additional gas-generating reactions may occur with sulfites,nitrites,thiosulfates (to give 142S and S03),
dithionites (S02), and carbonates. Can catalyze(increase the rate of)chemical reactions.Reacts explosively
with cyanogen fluoride,methanesulfonic acid or glycerol mixed with nitric acid.Reacts violently with arsenic
trioxide,phosphorus pentachloride, acetic anhydride, alkali metals,ammonium hydroxide,chlorosulfonic acid,
ethylenediamine,fluorine,potassium permanganate,oleurn,propylene oxide, vinyl acetate,mercury(II)oxide.
Emits highly corrosive fumes of hydrogen fluoride gas when heated [Sax, 9th ed., 1996,p. 1839]. Contact with
many silicon compounds and metal silicides causes violent evolution of gaseous silicon tetrafluoride [Mellor,
1956,Vol. 2, suppl. 1,p. 121].
Mixing in equal molar portions with any of the following substances in a closed container caused the
temperature and pressure to increase: acetic anhydride,2-aminoethanol, chlorosulfonic acid, aqueous ammonia
(48.7%),ethylenediamine, ethyleneimine,oleum, aqueous sulfuric acid(48.7% aqueous sodium hydroxide
(48.7%),propylene oxide, vinyl acetate [NFPA 1991].

Strong Oxidizing Agent
Known Catalytic Activity
Water-Reactive
Air &Water Reactions
Reaction with water is negligible unless acid strength is above 80-90% then heat from hydrolysis is extreme,
may cause severe burns [Merck, 11th ed. 19891.During sulfonation of mononitrobenzene by fuming sulfuric
acid, a leak from an internal cooling coil permitted water to enter the reaction tank.A violent eruption occurred
due to the heat of solution[MCA Case History 944 19631.
Fire hazard
It is highly reactive and capable of igniting finely-divided combustible materials on contact.When heated, it
emits highly toxic fumes. Avoid heat;water and organic materials.Sulfuric acid is explosive or incompatible
with an enormous array of substances. Can undergo violent chemical change at elevated temperatures and
pressure.May react violently with water.When heated, it emits highly toxic fumes.Hazardous polymerization
may not occur. (EPA, 1998)
Health Hazard
Corrosive to all body tissues. Inhalation of vapor may cause serious lung damage. Contact with eyes may result
in total loss of vision. Skin contact may produce severe necrosis.Fatal amount for adult:between 1 teaspoonful
and one-half ounce of the concentrated chemical. Even a few drops may be fatal if the acid gains access to the
trachea. Chronic exposure may cause tracheobronchitis, stomatitis, conjunctivitis, and gastritis. Gastric
perforation and peritonitis may occur and may be followed by circulatory collapse. Circulatory shock is often
the immediate cause of death.Those with chronic respiratory, gastrointestinal, or nervous diseases and any eye
and skin diseases are at greater risk. (EPA, 1998)
Reactivity Profile
SULFURIC ACID is strongly acidic.Reacts violently with bromine pentafluoride [Mellor 2 Supp. 1:1'72 1956].
Exploded with para-nitrotoluene at 80°C [Chem.Eng.News 27:2504]. An explosion occurred when
concentrated sulfuric acid was mixed with crystalline potassium permanganate in a vessel containing moisture.
Manganese heptoxide was formed,which explodes at 70°C [Delhez 1967].A mixture of acrylonitrile with
concentrated sulfuric acid must be kept well chilled,otherwise a vigorous exothermic reaction occurs [Chem.
Safety Data Sheet SD-31:8. 1949].Mixing sulfuric acid(96%)in equal portions with any of the following
substances in a closed container caused the temperature and pressure to increase: acetonitrile, acrolein, 2-
aminoethanol,ammonium hydroxide(28%), aniline,n-butyraldehyde,chlorosulfonic acid, ethylenediamine,
ethyleneimine,epichlorohydrin, ethylene cyanohydrin,hydrochloric acid(36%),hydrofluoric acid(48.7%),,
propiolactone,propylene oxide, sodium hydroxide, styrene monomer[NFPA 1991]. Sulfuric acid
(concentrated) is extremely hazardous in contact with carbides,bromates,chlorates, fulminates,picrates,and
powdered metals [Haz. Chem.Data 1966].Allyl chloride may polymerize violently under conditions involving
an acid catalyst, such as sulfuric acid [Ventrone 1971].React exothermically with sodium hypochlorite to
produce chlorine gas. Mixing chlorosulfuric acid and 98% sulfuric acid may evolve HCl [Subref: Anon,Loss
Prev.Bull. 1977, (013),2-3].Zinc iodide reacts violently with H2SO4. (Pascal, 1962,Vol. 5, 168).

Response Recommendations
Isolation and Evacuation
Excerpt from GUIDE 137 [Substances-Water-Reactive-Corrosive]:
As an immediate precautionary measure,isolate spill or leak area in all directions for at least 50 meters(150
feet)for liquids and at least 25 meters(75 feet)for solids.
SPILL: Increase,in the downwind direction, as necessary,the isolation distance shown above.
FIRE: If tank,rail car or tank truck is involved in a fire, ISOLATE for 800 meters(1/2 mile)in all directions;
also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2012)
Firefighting
Fight fire from safe distance or from protected location.Use care as water applied directly to this acid results in
evolution of heat and causes spattering. Cool containers that are exposed to flames with streams of water until
fire is out.Wear positive pressure breathing apparatus and special protective clothing.
Not flammable.For small fires use dry chemical or carbon dioxide.Use water on combustibles burning in
vicinity of this material.For large fires flood fire area with water from a distance.Do not get solid streams of
water on material. Move container from area if you can do so without risk. (EPA, 1998)
Non-Fire Response
Excerpt from GUIDE 137 [Substances-Water-Reactive- Corrosive]:
Fully encapsulating,vapor protective clothing should be worn for spills and leaks with no fire. Do not touch
damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it
without risk. Use water spray to reduce vapors; do not put water directly on leak, spill area or inside container.
Keep combustibles(wood,paper, oil,etc.) away from spilled material.
SMALL SPILL: Cover with DRY earth,DRY sand or other non-combustible material followed with plastic
sheet to minimize spreading or contact with rain.Use clean non-sparking tools to collect material and place it
into loosely covered plastic containers for later disposal. Prevent entry into waterways, sewers,basements or
confined areas. (ERG, 2012)
Protective Clothing
Skin:Wear appropriate personal protective clothing to prevent skin contact.
Eyes:Wear appropriate eye protection to prevent eye contact.
Wash skin: The worker should immediately wash,the skin when it becomes contaminated.
Remove:Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Change: No recommendation is made specifying the need for the worker to change clothing after the work shift.
http://l27.0.0.1:54673/report?key=CH5193 4/15/2015
.'NFm 1 -5-- M. I
Provide:Eyewash fountains should be provided(when concentration is>1%)in areas where there is any
possibility that workers could be exposed to the substance;this is irrespective of the recommendation involving
the wearing of eye protection.Facilities for quickly drenching the body should be provided(when concentration
is>1%)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.] (NIOSH,2003)
