Osmose MATERIAL SAFETY DATA SHEET
SPECIAL FIRE FIGHTING PROCEDURES: This product will not burn; 60% aqueous solution. When heated to decomposition, arsenic may
be emitted. If this material is involved in a fire or explosion, carbon dioxide or water may be used as an extinguishing agent. Wear complete
fire service protection equipment, including full-face MSHA/NIOSH approved self-contained breathing apparatus. For further information
regarding protective equipment, emergency responders should refer to 29CFR Appendix B to 1910.120 and the NFPA standards on chemical
protective clothing.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Chromic acid content of this product is a strong oxidizing agent; contact with strong reducing
agents may cause an explosion. May cause fire on contact with combustible materials. Closed containers may explode when exposed to
extreme heat (fire).
SECTION V - REACTIVITY DATA
IS THIS CHEMICAL STABLE UNDER NORMAL CONDITIONS OF HANDLING/STORAGE (Y/N)? Y
CONDITIONS TO AVOID (REGARDING STABILITY): Reducing Agents
INCOMPATIBILITY (MATERIALS TO AVOID): Strong reducing agents. Aluminum and zinc in an acid medium.
HAZARDOUS DECOMPOSITION PRODUCTS: Under certain conditions where aluminum and zinc (e.g. galvanized steel) are present,
arsine gas may be generated.
HAZARDOUS POLYMERIZATION POSSIBLE (Y/N)? N
CONDITIONS TO AVOID (REGARDING POLYMERIZATION): N/A
SECTION VI - HEALTH HAZARDS
ROUTES OF ENTRY: The principal routes of exposure for this solution are by skin or eye contact. If the pesticide application process
generates mist or particles, inhalation is an additional significant route of exposure. This solution is highly corrosive, as indicated by its pH.
Skin or eye contact may result in severe burns. Chronic skin exposure may result in skin ulcers. Inhalation of this solution is highly irritating,
and acute exposure by inhalation may result in chemical pneumonitis.
SIGNS AND SYMPTOMS OF ACUTE OVEREXPOSURE: Highly irritating to skin and eyes. Repeated dermal exposure may cause
dermatitis. Toxic by ingestion, causes gastroenteritis, esophageal pain, vomiting and anuria or oliguria.
CHRONIC OVEREXPOSURE: Repeated dermal exposure may cause dermatitis.
CHEMICAL LISTED AS A CARCINOGEN OR POTENTIAL CARCINOGEN?: N
路 NATIONAL TOXICOLOGY PROGRAM (Y/N): N
路 IARC MONOGRAPHS (Y/N): N
路 OSHA (Y/N): N
(For CARCINOGEN information, see Chronic Effects Notes following the First Aid Section.)
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Individuals with an existing (or history of) disease of the skin,
kidney, liver, lungs or nervous system may be at greater risk of developing either acute or chronic health effects.
TOXICOLOGICAL INFORMATION: Oral LD50 = > 50 mg/Kg; Dermal LD50 = < 200 mg/Kg
EMERGENCY AND FIRST AID PROCEDURES
) EMERGENCY PHONE NUMBER OF MANUFACTURER: CHEMTREC 1(800) 424-9300
1. INHALATION: For acute inhalation, remove the victim from exposure, restore breathing and seek medical attention immediately.
2. EYE CONTACT: Immediately flush with large quantities of water. Seek medical attention as soon as possible.
3. SKIN CONTACT: Immediately flush skin with large volumes of water. Seek medical attention as soon as possible.
4. INGESTION: Immediately seek medical attention; do not induce vomiting to an unconscious person. If conscious, give one glass
of milk, preferably containing 2 ounces of milk of magnesia or 3 egg whites, or give lime water or 1 tablespoon salt
in warm water; induce vomiting.
OADDITIONAL INFORMATIONO
NOTES TO PHYSICIAN: Treat for arsenic pentoxide (As2O5) and chromium trioxide (CrO3) exposure. Severe arsenic poisoning from
occupational exposure is unlikely. If it should occur, administer BL (dimercaprol) 10% in oil, IM, 3 mg/kg for each injection - day 1 and 2,
every four hours; day 3, every 6 hours; day 4-14, every 12 hours. Consider gastric lavage (if vomiting has not already occurred).
CHRONIC EFFECTS: IARC, NTP and OSHA do not consistently distinguish among arsenic or chromium compounds, but list inorganic
arsenic and chromium and certain specific chromium compounds as human carcinogens. Such listings have been based upon cancer in
human populations following long term consumption of inorganic trivalent arsenic, inhalation and skin contact with inorganic trivalent arsenical
compounds and the combined inhalation of arsenic trioxide, sulfur dioxide and other particulate from ore smelting in arsenic trioxide
production. In 1993, ACGIH listed 鈥淎rsenic, elemental [7440-38-2] and inorganic compounds (except Arsine), as As鈥? as a confirmed human
carcinogen. In addition, cancers in humans have followed long term occupational exposure to certain non-water soluble hexavalent
chromium. This product does not contain trivalent arsenic or non-water-soluble hexavalent chromium compounds. Furthermore,
epidemiology studies and cross sectional health studies of treating plant workers would indicate that this product is not a carcinogen when
used in accordance with customary practices found in the wood preserving industry.
For pesticide applicators, read and understand the label thoroughly. The EPA PEL program is part of the label.

SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
UNITED STATES DEPARTMENT OF TRANSPORTATION SHIPPING DESCRIPTION:
Corrosive liquid, toxic, n.o.s., 8, UN2922, PGIII (Arsenic Acid, Chromic Acid), RQ
CANADA鈥橲 TRANSPORTATION OF DANGEROUS GOODS SHIPPING DESCRIPTION:
Corrosive liquid, toxic, n.o.s., (Arsenic Acid, Chromic Acid), Class 8, (6.1), UN2922, PGIII, RQ
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Engineering controls are the preferred method for controlling exposure to
chemicals. If engineering controls are not feasible, then personal protective equipment should be utilized. Read Osmose Operations manual.
OTHER PRECAUTIONS Launder contaminated clothing before reuse. If interior of shoes are contaminated, either directly or through
penetration, delayed skin burns may occur, therefore discard. READ PRODUCT LABEL!
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Avoid contact with solution. Prevent spread of the spill or leak.
Recover or neutralize free standing liquid with Osmose Neutralizing compound or sawdust. Collect absorbent and contaminated soil in DOT
approved containers. This material is toxic to fish and other wildlife, do not allow it to contaminate waterways. Individuals involved in clean-
up should be protected from contact with the solution by using appropriate protective equipment.
WASTE DISPOSAL METHODS: Dispose in accordance with all Federal (Resource Conservation and Recovery Act), State and Local laws.
Excess chemical and waste material collected from a release or spill must be disposed of in an approved hazardous waste disposal site in
accordance with RCRA guidelines. Containers may be triple rinsed and then buried in a sanitary landfill or removed to a drum reclaimer. The
RQ for this material is one pound. In the event of a spill exceeding the RQ, the same must be reported to the National Response Center (1-
800-424-8802).
SECTION VIII - CONTROL MEASURES
RESPIRATORY PROTECTION: When respiratory exposure can exceed 0.01 mg/M3, 29 CFR 1910.1018 states that a half-mask air purifying
respirator equipped with high efficiency particulate filters is recommended. When environmental airborne concentrations are greater than this
level, consult 29 CFR 1910.1010 for guidelines and appropriate respiratory protection. Read product label.
VENTILATION REQUIREMENTS: As necessary in order not to exceed PEL鈥檚.
LOCAL EXHAUST: Sufficient
PROTECTIVE GLOVES: 29 CFR 1910.1018 requires that workers wear gloves (NBR, natural rubber, neoprene, coated vinyl or
PVC).
EYE PROTECTION: Chemical goggles and face shield.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: An apron and other equipment necessary to avoid dermal contact.
WORK/HYGIENIC PRACTICES: Wash hands with soap and water before eating, drinking, smoking, and after work.
