3 HAZARDS IDENTIFICATION
Emergency Overview
Water white to pale yellow liquid, faint Sulfur odor
DANGER!
CAUSES EYE AND SKIN BURNS. MAY CAUSE BLINDNESS.
CAUSES RESPIRATORY TRACT IRRITATION.
MAY BE HARMFUL IF SWALLOWED.
MAY BE HARMFUL IF ABSORBED THROUGH SKIN
Potential Health Effects
Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material. Based on
single exposure animal tests, it is considered to be slightly toxic if swallowed, no more than slightly toxic if absorbed
through skin or inhaled, and corrosive to eyes and skin. If swallowed, this material may cause mild to severe burns to
the mouth, throat and digestive tract. Vapor is severely irritating to the eyes, nose and respiratory tract and may
produce tearing of the eyes, coughing and breathing difficulty. Medical conditions that may be aggravated by exposure
to this material include lung disease or limited respiratory capacity.

4 FIRST AID MEASURES
IF IN EYES, immediately flush with plenty of water for at least 15 minutes. Get medical attention immediately.
IF ON SKIN, immediately flush with plenty of water. Remove contaminated clothing and shoes. Get medical
attention. Wash clothing before reuse. Destroy contaminated shoes.
IF SWALLOWED, do NOT induce vomiting. Give water to drink. Get medical attention immediately. NEVER
GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.
IF INHALED, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention.

Extinguishing Media
Use extinguishing media appropriate to surrounding fire conditions.
Fire Fighting Instructions
This material is not flammable. However, as in fighting any fire, fire fighters and others who may be exposed to
products of combustion should wear full fire fighting gear (full Bunker Gear) and self-contained breathing
apparatus (pressure demand NIOSH approved of equivalent). Fire fighting equipment should be thoroughly
decontaminated after use.
Fire and Explosion Hazards
Material does not support combustion. See Section 10 for information on hazardous decomposition products.
6 ACCIDENTAL RELEASE MEASURES
In Case of Spill or Leak
Small spills: soak up with an inert absorbent. Scoop up and place in a clean, dry container. Consult with
environmental engineer or professional to determine if neutralization is appropriate and for handling
procedures for residual materials.
Large spills: Pump into marked containers for disposal or reclamation. Consult a regulatory specialist to
determine appropriate state or local reporting requirements, for assistance in waste characterization and/or
hazardous waste disposal and other requirements listed in pertinent environmental permits.
7 HANDLING AND STORAGE
Handling
Do not get in eyes, on skin or on clothing.
Keep container closed.
Use only with adequate ventilation.

7 HANDLING AND STORAGE
Wash thoroughly after handling.
Do not taste or swallow.
Do not add water to acid while in container because heat release may cause spattering.
Never use pressure to empty drum.
Emptied container retains vapor and product residue. Observe all labeled safeguards until container is
cleaned, reconditioned or destroyed.
Storage
This material is not hazardous under normal storage conditions; however, material should be stored in
closed containers, in a secure area to prevent container damage and subsequent spillage.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures. Provide ventilation if necessary to minimize
exposures. If practical, use local mechanical exhaust ventilation at sources of air contamination such as
open process equipment. Consult ACGIH ventilation manual or NFPA Standard 91 for design of exhaust
systems.
Eye / Face Protection
Where there is potential for eye contact, wear a face shield, chemical goggles, and have eye flushing
equipment immediately available.
Skin Protection
Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin
contact. Consult glove manufacturer to determine appropriate type glove material for given application.
Wear chemical goggles, a face shield, and chemical resistant clothing such as a rubber apron when
splashing may occur. Rinse immediately if skin is contaminated. Remove contaminated clothing promptly
and wash before reuse. Clean protective equipment before reuse. Provide a safety shower at any location
where skin contact can occur. Wash skin thoroughly after handling.
Respiratory Protection
Avoid breathing vapor or mist. Where airborne exposure is likely, use NIOSH approved respiratory
protection equipment appropriate to the material and/or its components. Full facepiece equipment is
recommended and, if used, replaces need for face shield and/or chemical goggles. If exposures cannot be
kept at a minimum with engineering controls, consult respirator manufacturer to determine appropriate type
equipment for given application. Observe respirator use limitations specified by NIOSH or the manufacturer.
For emergency and other conditions where there may be a potential for significant exposure, use an
approved full face positive-pressure, self-contained breathing apparatus or positive-pressure airline with
auxiliary self-contained air supply. Respiratory protection programs must comply with 29 CFR ?1910.134.

-Only those components with exposure limits are printed in this section.
-Skin contact limits designated with a "Y" above have skin contact effect. Air sampling alone is insufficient to accurately quantitate
exposure. Measures to prevent significant cutaneous absorption may be required.
-ACGIH Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic reactions.
-WEEL-AIHA Sensitizer designator with a value of "Y" above means that exposure to this material may cause allergic skin reactions.

11 TOXICOLOGICAL INFORMATION
Inhalation - No More than Slightly Toxic to Rats (6-hr LC0 0.74 mg/l)
Eye Irritation - Corrosive to Rabbits
Skin Irritation - Corrosive to Rabbits
No skin allergy was observed in guinea pigs following repeated exposure. No adverse effects were reported in
rats repeatedly exposed in the feed. Repeated exposure by inhalation produced severe signs of irritation in the
noses of rats with partial recovery noted after two weeks of no exposure. At higher exposure levels, decreased
body weights, clinical signs of irritation and mortality were noted. No effects were noted in the offspring of rats
exposed orally during pregnancy. No genetic changes were observed in tests using bacteria, animal cells or
animals.
12 ECOLOGICAL INFORMATION
Ecotoxicological Information
Data on this material and/or its components are summarized below.
This material is moderately toxic to Daphnia magna (24-hr EC50 1.7 mg/l). It is slightly toxic to rainbow trout
(96-hr LC50 73 mg/l) and algae (72-hr IC50 14-16 mg/l), and is practically non-toxic to guppies [96-hr LC50
>770 mg/l (100%); >1,110 mg/l (70%)]. The acute oral LD50 in coturnix quail is 1,000 mg/kg. Reduced egg
fertility was noted after male coturnix quail were administered a single oral dose of 421 mg/kg and evaluated for
their ability to produce fertile eggs upon mating.
