Procedure:
Wear NIOSH -approved self-contained breathing apparatus (SC13A). Use water spray to
keep containers cool and to knock down fumes. CAUTION: when subject to excess heat,
product releases additional sulfur dioxide gas.
Precaution if Steps should be taken to contain spilled liquids and prevent discharges to streams
Spilled or Released: or sewer systems.
Neutralizing Chemicals: Neutralize with appropriate alkali such as sodium hydroxide, or soda ash to neutral
pH. Avoid conditions where the pH of spilled material is maintained at lower than
H 6, since sulfur dioxide can be released at ambient temperatures below this pH.

PRECAUTIONARY STATEMENTS:
:* Do not breath dust/ fume/ gas/ mist/ vapors/ spray.
=> Wash hands, face and skin thoroughly after handling.
=> Wear protective gloves/ protective clothing/ eye protection/ face protection.
=> IF SWALLOWED: rinse mouth. DO NOT induce vomiting.
=> IF ON SKIN (or hair): Remove/ Take off immediately all contaminated clothing. Rinse skin with water/shower.
=> Wash contaminated clothing before reuse.
=> IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
=> Immediately call a POISON CENTER or doctor/physician.
=> Specific treatment (see on this label).
=> IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do.
Continue rinsing.
=> Dispose of contents/ container in full compliance with Federal, State, and local regulations.

SKIN:
Immediately flush skin with plenty of water, for at least 15 minutes, while removing contaminated clothing and
shoes. GET IMMEDIATE MEDICAL ATTENTION!
Place contaminated clothing in closed container for storage until laundered or discarded. If clothing is to be laun-
dered, inform person performing operation of contaminant's hazardous properties. Discard contaminated leather
goods.
EYE:
Flush immediately with large amounts of water for at least 15 minutes. Eyelids should be held away from the eye-
ball to ensure thorough rinsing. GET IMMEDIATE MEDICAL ATTENTION!
INHALATION:
Remove to fresh air. If not breathing, institute rescue breathing. If breathing is difficult, ensure airway is clear and
give oxygen. Keep affected person warm and at rest. GET IMMEDIATE MEDICAL ATTENTION!
INGESTION:
If victim is conscious and alert, give 1-3 glasses of water to dilute stomach contents. Rinse mouth out with water.
Do not induce vomiting unless directed by medical personnel. Never give anything by mouth to an unconscious
person. If spontaneous vomiting occurs keep head below hips to prevent aspiration and monitor for breathing diffi-
culty.
Keep affected person warm and at rest. GET IMMEDIATE MEDICAL ATTENTION!

HAZARDOUS COMBUSTION PRODUCTS:
FIRE HAZARD Not flammable
Decomposes to form sulfur dioxide and sulfur trioxide.
EXPLOSION HAZARD Reacts with most metals (especially dilute concentrations): Hydrogen gas release
(EXTREMELY FLAMMABLE, EXPLOSIVE). Risk of explosion if acid combined with
water, organic materials or base solutions in enclosed spaces (Vacuum trucks,
tanks). Mixing acids of different strengths can also pose an explosive risk in an
enclosed space/container.
EXINGUISHING MEDIA ERG (Emergency Response Guidebook): Guide 137
When material is not involved in fire, do not use water on material itself.
Page 2
Distributed by Industrial Chemicals, Inc. 2540 Bellwood Road, Richmond, VA 23237. 804-275-9292

EXTINGUISHING MEDIA:
Small fire: Use carbon dioxide or dry chemical to extinguish fire.
Large fire: Flood fire area with large quantities of water, while knocking down vapors with fog. If insufficient
water supply, knock down vapors only
Tank fire: Cool containers with flooding quantities of water until well after fire is out. Do not get water
inside containers. Evacuate immediately if sound from safety vents or discoloration of tank. Stay
clear of tanks engulfed in fire.
PROTECTIVE EQUIPMENT:
Evacuate personnel to a safe area. Keep personnel removed and upwind of fire. Generates heat
upon addition of water, with possibility of spattering. Wear full protective clothing. Runoff from
fire control may cause pollution. Neutralize run-off with sodium bicarbonate or soda ash to
prevent corrosion of metals and formation of hydrogen gas. Wear self-contained breathing
apparatus if fumes or mists are present.
EMERGENCY PROCEDURES: Review Fire and Explosion Hazards [Section #5] . Take immediate
steps to stop and contain release if possible.
CLEAN-UP METHODS: Soak up small spills with dry sand or diatomaceous earth. Contain large
spills and cautiously dilute and neutralize with lime or soda ash. Caution
should be exercised regarding personnel safety and exposure to the
released product.
Notify local authorities and the National Response Center, if required. If
the product is spilled and not recovered, or is recovered as a waste for
treatment or disposal, the Reportable Quantity (US DOT) is 1,000 lbs
(based on the sulfuric acid content of the solution spilled).
PROTECTIVE EQUIPMENT: See "Exposure Controls/Personal Protection" [Section #8].
HANDLING:
DO NOT get in eyes, on skin, or on clothing. Avoid breathing vapors or mist. Wear approved respirators if
adequate ventilation can not be provided. Wash thoroughly after handling. Do not eat, drink or smoke in areas of
use or storage. NEVER add water to acid.
STORAGE:
Avoid contact with combustible materials, water, metals and alkalis. Store in a vented container. This material
should be stored and shipped in containers specially designed for sulfuric acid. DO NOT add water or other
products to contents in containers as violent reactions with resulting high heat, pressure, and/or generation of
hazardous acid mists. Page 3

ENGINEERING CONTROLS:
Ventilation and other forms of engineering controls are the preferred means for controlling exposures.
PERSONAL PROTECTION:
Chemical splash goggles; Full-length face shield/chemical splash goggles combination; Acid -proof gauntlet gloves,
and boots; Appropriate NIOSH approved respiratory protection if acid mist is present.
An apron can be used in place of acid proof suit if the employer's risk assessment deems it is safe for the type of
handling taking place (i.e. laboratories and small quantities).
For emergencies where possibility of exposure is high, wear complete acid suit with hood, boots, and gloves.
NIOSH approved respiratory protection should be worn if acid mist is present or exposure limits are exceeded.

STABILITY:
Stable under normal, ambient conditions
REACTIVITY:
Reacts violently with water, organic substances and base solutions with evolution
of heat and hazardous mists.
DECOMPOSITION:
Possibility of,hazardous decomposition if heated and in contact with sources of
ignition. Release of toxic gases and vapors (Sulfur oxides (SO2, S03)).
POLYMERIZATION:
Will not occur
MATERIALS TO AVOID:
Water; alkaline solutions; metals, metal powder; carbides; chlorates; fulminates;
nitrates; picrates; strong oxidizing, reducing or combustible organic materials.
Hazardous gases are evolved on contact with chemicals such as cyanides, sulfides,
and carbides.
ROUTES OF ENTRY: Ingestion. Inhalation. Skin and eye contact.
CARCINOGENICITY: IARC has determined that there is sufficient evidence for the carcinogenicity of
occupational exposure to strong inorganic acid mists containing sulfuric acid in
humans (IARC Class 1)
ACUTE TOXICITY: ORAL acute (LD50): 2140 mg/kg (Rat).
TOXILOGICAL Acute or chronic overexposure to this material or its components may cause
INFORMATION: systemic toxicity, including adverse effects to the following: kidney, liver, teeth,
respiratory and cardiovascular systems.
Exposure to components of this material may cause the following specific
symptoms, depending on the concentration and duration of exposure: attacks
enamel of teeth, vomiting, clammy skin, weak and rapid pulse.
Other symptoms of exposure may include the following: shallow respiration,
chronic bronchitis, lung function changes and scanty urine.
PRE-EXISTING CONDITIONS AGGRAVATED BY EXPOSURE:
Pre-existing medical conditions which may be aggravated by exposure include
disorders of the skin and respiratory system.
ALL WORK PRACTICES MUST BE AIMED AT ELIMINATING ENVIRONMENTAL CONTAMINATION.
