4. FIRST AID MEASURES
First aid measures
General advice In case of accident or if you feel unwell, seek medical advice immediately (show directions
for use or safety data sheet if possible).
Inhalation Remove to fresh air. If not breathing, utilize bag valve mask or other form of barrier device
to institute rescue breathing. If breathing is difficult, ensure airway is clear, give oxygen and
continue to monitor. If heart has stopped, immediately begin cardiopulmonary resuscitation
(CPR). Keep affected person warm and at rest. Get immediate medical attention.
Skin contact Immediately wash exposed skin with plenty of soap and water while removing contaminated
clothing and shoes. May be absorbed through the skin in harmful amounts. Get medical
attention if irritation persists. Any injection injury from high pressure equipment should be
evaluated immediately by a physician as potentially serious (See NOTES TO PHYSICIAN).
Place contaminated clothing in closed container until cleaned or discarded. If clothing is to
be laundered, inform the person performing the operation of contaminant's hazardous
properties. Destroy contaminated, non-chemical resistant footwear.
Eye contact Flush immediately with large amounts of water for at least 15 minutes. Gently remove
contacts while flushing. Eyelids should be held away from the eyeball to ensure thorough
rinsing. Gently remove contacts while flushing. Get medical attention if irritation persists.
Ingestion Do not induce vomiting because of danger of aspirating liquid into lungs, causing serious
damage and chemical pneumonitis. If spontaneous vomiting occurs, keep head below hips,
or if patient is lying down, turn body and head to side to prevent aspiration and monitor for
breathing difficulty. Never give anything by mouth to an unconscious person. Keep affected
person warm and at rest. Get immediate medical attention.
Most important signs and symptoms, both short-term and delayed with overexposure
Adverse effects Irritating to the skin and mucous membranes. Symptoms may include redness, itching, and
inflammation. May cause nausea, vomiting, diarrhea, and signs of nervous system
depression: headache, drowsiness, dizziness, loss of coordination, disorientation and
fatigue. Aspiration hazard. May cause coughing, chest pains, shortness of breath,
pulmonary edema and/or chemical pneumonitis. Prolonged or repeated exposure may
cause adverse effects to the thymus, liver, and bone marrow. Repeated or prolonged skin
contact may cause drying, reddening, itching and cracking.
Indication of any immediate medical attention and special treatment needed
Notes to physician INHALATION: This material (or a component) sensitizes the myocardium to the effects of
sympathomimetic amines. Epinephrine and other sympathomimetic drugs may initiate
cardiac arrhythmias in individuals exposed to this material. Administration of
sympathomimetic drugs should be avoided.
SKIN: Leaks or accidents involving high-pressure equipment may inject a stream of material
through the skin and initially produce an injury that may not appear serious. Only a small
puncture wound may appear on the skin surface but, without proper treatment and
depending on the nature, original pressure, volume, and location of the injected material,
can compromise blood supply to an affected body part. Prompt surgical debridement of the
wound may be necessary to prevent irreversible loss of function and/or the affected body
part. High pressure injection injuries may be SERIOUS SURGICAL EMERGENCIES.

INGESTION: This material represents a significant aspiration and chemical pneumonitis
hazard. Induction of emesis is not recommended.
5. FIRE-FIGHTING MEASURES
Suitable extinguishing media For small fires, Class B fire extinguishing media such as CO2, dry chemical, foam or water
spray can be used. For large fires, water spray, fog or foam can be used. Firefighting
should be attempted only by those who are adequately trained and equipped with proper
protective equipment.
Unsuitable extinguishing media Do not use straight water streams to avoid spreading fire.
Specific hazards arising from the
chemical
This product has been determined to be a flammable liquid per the OSHA Hazard
Communication Standard and should be handled accordingly. May accumulate electrostatic
charge and ignite or explode. Vapors may travel along the ground or be moved by
ventilation and ignited by many sources such as pilot lights, sparks, electric motors, static
discharge, or other ignition sources at locations distant from material handling. Flashback
can occur along vapor trail. For additional fire related information, see NFPA 30 or the
Emergency Response Guidebook 128.
Hazardous combustion products Smoke, carbon monoxide, and other products of incomplete combustion.
Explosion data
Sensitivity to mechanical
impact:
No.
Sensitivity to static discharge:Yes.
Special protective equipment and
precautions for firefighters
Firefighters should wear full protective clothing and positive-pressure self-contained
breathing apparatus (SCBA) with a full face-piece, as appropriate. Avoid using straight
water streams. Water spray and foam must be applied carefully to avoid frothing and from
as far a distance as possible. Avoid excessive water spray application. Keep surrounding
area cool with water spray from a distance and prevent further ignition of combustible
material. Keep run-off water out of sewers and water sources.
Additional firefighting tactics FIRES INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance
or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities
of water until well after the fire is out. Do not direct water at source of leak or safety devices;
icing may occur. Withdraw immediately in case of rising sound from venting safety devices
or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. For massive fire,
use unmanned hose holders or monitor nozzles: if this is impossible, withdraw from area
and let fire burn.
EVACUATION: Consider initial downwind evacuation for at least 1000 feet. If tank, rail car
or tank truck is involved in a fire, ISOLATE for 5280 feet (1 mile) in all directions; also,
consider initial evacuation of 5280 feet (1 mile) in all directions.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions Keep public away. Isolate and evacuate area. Shut off source if safe to do so. Eliminate all
ignition sources. All contaminated surfaces will be slippery.
Protective equipment Use personal protection measures as recommended in Section 8.
Emergency procedures Advise authorities and National Response Center (800-424-8802) if the product has
entered a water course or sewer. Notify local health and pollution control agencies, if
appropriate.
Environmental precautions Avoid release to the environment. Avoid subsoil penetration.

Methods and materials for
containment
Contain liquid with sand or soil. Prevent spilled material from entering storm drains, sewers,
and open waterways.
Methods and materials for cleaning
up
Use suitable absorbent materials such as vermiculite, sand, or clay to clean up residual
liquids. Recover and return free product to proper containers. When recovering free liquids
ensure all equipment is grounded and bonded. Use only non-sparking tools.
7. HANDLING AND STORAGE
Safe handling precautions NEVER SIPHON THIS PRODUCT BY MOUTH. Use appropriate grounding and bonding
practices. Static accumulating flammable liquid. Bonding and grounding may be insufficient
to eliminate the hazard from static electricity. Do not expose to heat, open flames, strong
oxidizers or other sources of ignition. Vapors may travel along the ground or be moved by
ventilation. Flashback may occur along vapor trails. No smoking. Use only non-sparking
tools. Avoid breathing fumes, gas, or vapors. Use only with adequate ventilation. Avoid
repeated and prolonged skin contact. Use personal protection measures as recommended
in Section 8. Exercise good personal hygiene including removal of soiled clothing and
prompt washing with soap and water. Do not cut, drill, grind or weld on empty containers
since explosive residues may remain. Refer to applicable EPA, OSHA, NFPA and
consistent state and local requirements.
Hydrocarbons are basically non-conductors of electricity and can become electrostatically
charged during mixing, filtering, pumping at high flow rates or loading and transfer
operations. If this charge reaches a sufficiently high level, sparks can form that may ignite
the vapors of flammable liquids. Sudden release of hot organic chemical vapors or mists
from process equipment operating under elevated temperature and pressure, or sudden
ingress of air into vacuum equipment may result in ignition of vapors or mists without the
presence of obvious ignition sources. Nozzle spouts must be kept in contact with the
containers or tank during the entire filling operation.
Portable containers should never be filled while in or on a motor vehicle or marine craft.
Containers should be placed on the ground. Static electric discharge can ignite fuel vapors
when filling non-grounded containers or vehicles on trailers. The nozzle spout must be kept
in contact with the container before and during the entire filling operation. Use only
approved containers.
A buildup of static electricity can occur upon re-entry into a vehicle during fueling especially
in cold or dry climate conditions. The charge is generated by the action of dissimilar fabrics
(i.e., clothing and upholstery) rubbing across each other as a person enters/exits the
vehicle. A flash fire can result from this discharge if sufficient flammable vapors are
present. Therefore, do not get back in your vehicle while refueling.
Cellular phones and other electronic devices may have the potential to emit electrical
charges (sparks). Sparks in potentially explosive atmospheres (including fueling areas
such as gas stations) could cause an explosion if sufficient flammable vapors are present.
Therefore, turn off cellular phones and other electronic devices when working in potentially
explosive atmospheres or keep devices inside your vehicle during refueling.
High-pressure injection of any material through the skin is a serious medical emergency
even though the small entrance wound at the injection site may not initially appear serious.
These injection injuries can occur from high-pressure equipment such as paint spray or
grease or guns, fuel injectors, or pinhole leaks in hoses or hydraulic lines and should all be
considered serious. High pressure injection injuries may be SERIOUS SURGICAL
EMERGENCIES (See First Aid Section 4).
Storage conditions Store in properly closed containers that are appropriately labeled and in a cool,
well-ventilated area. Do not store near an open flame, heat or other sources of ignition.
Incompatible materials Strong oxidizing agents.

PETROLEUM MIDDLE DISTILLATES: Petroleum derived middle distillates have produced skin tumors in mice after repeated and
prolonged skin contact. Additional studies indicated prolonged skin irritation contributes to tumor development. Repeated dermal
exposures to high concentrations in test animals resulted in reduced litter size and weight, and increased fetal resorptions at doses
Reactivity The product is non-reactive under normal conditions.

toxic to the mother. Inhalation exposure to high concentrations resulted in respiratory tract irritation, lung
changes/infiltration/accumulation, and reduction in lung function. Repeated dermal application of petroleum gas oils resulted in
decreased liver, thymus, and spleen weights, and altered bone marrow function. Microscopic alterations included liver hypertrophy
and necrosis, decreased hematopoiesis and lymphocyte depletion. Altered mental state, drowsiness, peripheral motor neuropathy,
irreversible brain damage (so-called Petrol Sniffer's Encephalopathy), delirium, seizures, and sudden death have been reported
from repeated overexposure to some hydrocarbon solvents, naphthas, and gasoline.
NAPHTHALENE: Excessive exposure to naphthalene may cause nausea, vomiting, diarrhea, blood in the urine, and a yellow color
to the skin. Lifetime inhalation exposure of laboratory rodents to naphthalene resulted in cancers of the respiratory tract in male and
female rats. A small increase in cancer of the lung was observed in female mice, but no evidence of lung cancer was observed in
male mice. Long-term exposure to excessive airborne naphthalene concentrations may result in destruction of red blood cells, a
condition referred to as hemolytic anemia.
DIESEL EXHAUST: The combustion of diesel fuels produces gases including carbon monoxide, carbon dioxide, oxides of nitrogen
and/or sulfur, and hydrocarbons that can be irritating and hazardous with overexposure. Long-term occupational overexposure to
diesel exhaust and diesel exhaust particulate matter has been associated with an increased risk of respiratory disease, including
lung cancer, and is characterized as a “known human carcinogen” by the International Agency for Research on Cancer (IARC), as
“a reasonably anticipated human carcinogen” by the National Toxicology Program, and as “likely to be carcinogenic to humans” by
the EPA, based upon animal and occupational exposure studies. However, uncertainty exists with these classifications because of
deficiencies in the supporting occupational exposure/epidemiology studies, including reliable exposure estimates. Lifetime animal
inhalation studies with pulmonary overloading exposure concentrations of diesel exhaust emissions have produced tumors and
other adverse health effects. However, in more recent long-term animal inhalation studies of diesel exhaust emissions, no increase
in tumor incidence and in fact a substantial reduction in adverse health effects along with significant reductions in the levels of
hazardous material emissions were observed and are associated with fuel composition alterations coupled with new technology
diesel engines.
Adverse effects related to the physical, chemical and toxicological characteristics

appropriate disposal.

SECTION 7: HANDLING AND STORAGE

Precautions for Safe Handling: Do not breathe dust. Do not rely on your sight to determine if dust is in the air.
Silica may be in the air without a visible dust cloud. Use normal precautions against bag breakage or spills of bulk
material. Avoid creation of respirable dust. Use good housekeeping in storage and use areas to prevent accumulation
of dust in work area.

To reduce the risk of developing silicosis, lung cancer and other adverse health effects, the ACGIH recommends that the
industrial hygienist use every means available to keep exposures below the recommended TLV. NIOSH recommends
reducing airborne exposure levels as low as possible below NIOSH’s recommended exposure limit, substituting less
hazardous materials when feasible, using appropriate respiratory protection when source controls cannot keep exposures
below the recommended limit and making medical examinations available to exposed workers.

Use adequate ventilation and dust collection. To minimize exposure, wear a respirator approved for silica dust when using,
handling, storing or disposing of this product or bag. Refer to the most recent government and local regulations when
selecting a respirator. Maintain, clean and fit test respirators in accordance with the most recent government and local
SDS No: 011-U-GHS
Page 3 of 8 Date Prepared: April 2015
regulations. Maintain and test ventilation and dust collection equipment. Launder clothing that has become dusty. Empty
containers (bags, bulk containers, storage tanks, etc.) retain silica residue and must be handled in accordance with the
provisions of this Material Safety Data Sheet. WARN and TRAIN employees in accordance with state and federal
regulations.

WARN YOUR EMPLOYEES (AND YOUR CUSTOMERS AND USERS IN CASE OF RESALE) BY POSTING,
AND OTHER MEANS, OF THE HAZARDS AND OSHA AND ANY OTHER APPLICABLE REGULATORY
PRECAUTIONS TO BE USED. PROVIDE TRAINING FOR YOUR EMPLOYEES ABOUT OSHA
PRECAUTIONS.

Dust can accumulate electrostatic charges due to friction from transfer and mixing operations and cause an electrical spark
(ignition source) which can ignite flammable liquids and atmospheres. Provide adequate precautions when adding this
product to flammable and combustible mixtures like paints and coating, such as electrical grounding and bonding, inert
atmosphere or non-sparking tools. However, bonding and grounds may not eliminate the hazard for static accumulation.

SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION

Exposure Guidelines:

Definitions:
NIOSH means National Institute for Occupational Safety and Health.
REL means the NIOSH Recommended Exposure Limit.
TLV means American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value.
TWA means time-weighted average.

OSHA PEL and MSHA Exposure Limit for Crystalline Silica, Quartz 10 mg/m3
(Respirable measured as an 8-hour TWA) % Silica + 2

TLV- 0.025 mg/m3 8-hour TWA (respirable fraction)

In 2006 the ACGIH lowered the TLV for Silica, Crystalline: α-Quartz and Cristobalite to 0.025 mg/m3 stating in the
Documentation of the TLV “Because the time between exposure and signs of fibrosis is characteristically very long, as much
as 30 to 40 years, the margin of safety for exposure to crystalline silica at the proposed TLV-TWA is not known precisely.
Given the observed association between silicosis and lung cancer, it is recommended that air concentrations be maintained as
far below the proposed TLV as prudent practices permit. The recommended TLV-TWA of 0.025 mg/m3, respirable
particulate mass, is intended to prevent pulmonary fibrosis that may be a risk factor for lung cancer. An A2, Suspected
Human Carcinogen, notation is based on the demonstrated association between lung cancer and the presence of silicosis.”
The documentation further states “A lack of toxicological and industrial hygiene data does not permit the recommendation of
a TLV-STEL. However, it should be noted that high exposures of short duration to freshly fragmented crystalline particles do
produce an acute and rapidly progressive form of silicosis. The reader is encouraged to review the section on Excursion
Limits in the “Introduction to the Chemical Substances” of the current TLVs and BEIs book for guidance and control of
excursions above the TLV-TWA, even when the 8-hour TWA is within the recommended limits”

SDS No: 011-U-GHS
Page 4 of 8 Date Prepared: April 2015
NIOSH has issued its REL of 50 micrograms respirable free silica per cubic meter of air (0.05 mg/m3) as determined by a full
shift sample up to 10-hour working day, 40 hours per week. NIOSH has recommended that OSHA and MSHA adopt the
NIOSH REL as the OSHA PEL and the MSHA Exposure Limit. The 1974 NIOSH Criteria for a Recommended Standard for
Occupational Exposure to Crystalline Silica should be consulted for more detailed information. Additionally, NIOSH, In a
publication entitled NIOSH Hazard Review Health Effects of Occupational Exposure to Respirable Silica (April 2002),
NIOSH stated “…that workers have a significant risk of developing chronic silicosis when they are exposed to respirable
crystalline silica over a working lifetime at the current Occupational Safety and Health Administration (OSHA) permissible
exposure limit (PEL), the Mine Safety and Health Administration (MSHA) PEL, or the National Institute for Occupational
Safety and Health (NIOSH) recommended exposure limit (REL). …Current sampling and analytical methods used to
evaluate occupational exposure to respirable crystalline silica do not meet the accuracy criterion needed to quantify
exposures at concentrations below the NIOSH REL of 0.05 mg/m3 as a time-weighted average (TWA) for up to a 10-hr
workday during a 40-hr workweek. Until improved sampling and analytical methods are developed for respirable crystalline
silica, NIOSH will continue to recommend an exposure limit of 0.05 mg/m3 to reduce the risk of developing silicosis, lung
cancer, and other adverse health effects. NIOSH also recommends minimizing the risk of illness that remains for workers
exposed at the REL by substituting less hazardous materials for crystalline silica when feasible, by using appropriate
respiratory protection when source controls cannot keep exposures below the NIOSH REL, and by making medical
examinations available to exposed workers.”

Crystalline silica exists in several forms, the most common of which are quartz (i.e. this product), trydimite and cristobalite,
with quartz being the most common form found in nature. If quartz is heated to more than 870°C, it can change form to
trydimite and if quartz is heated to more than 1450°C, it can change form to cristobalite.

Appropriate Engineering Controls: Use local exhaust as required to maintain exposures as far as possible below
applicable occupational exposure limits. See also ACGIH "Industrial Ventilation - A Manual for Recommended
Practice" (current edition). Control of exposure to dust must be accomplished as far as feasible by accepted engineering
control measures (for example, enclosure or confinement of the operation, general or local exhaust ventilation and
substitution of less toxic materials).

Personal Protective Equipment:
Respiratory Protection: When effective engineering controls are not feasible, or while they are being implemented,
appropriate respiratory protection must be used. Use appropriate respiratory protection for respirable particulates based on
consideration of airborne workplace concentrations and duration of exposure arising from intended end use. Refer to the most
recent government and local standards.

Gloves: Protective gloves recommended.

Eye Protection: Safety glasses or goggles recommended.

Other Protective Equipment/Clothing: As appropriate for the work environment. Dusty clothing should be laundered
before reuse.

SECTION 11: TOXICOLOGICAL INFORMATION

Information on Toxicological Effects

Potential Health Effects:

Inhalation: Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be
occurring. Inhalation of dust may have serious chronic health effects (see below Repeat Dose Toxicity.)

Skin Contact: No adverse effects expected.

Eye Contact: Contact may cause mechanical irritation and possible injury.

Ingestion: No adverse effects expected for normal, incidental ingestion.

Chronic Health Effects: See Repeat Dose Toxicity below with respect to silicosis, cancer status and other data with possible
relevance to human health.

Signs and Symptoms of Exposure: Exposure to dust may cause mucous membrane and respiratory irritation, cough, sore
throat, nasal congestion, sneezing and shortness of breath. However, there may be no immediate signs or symptoms of
exposure to hazardous concentrations of respirable crystalline silica (quartz). See Repeat Dose Toxicity below for symptoms
of silicosis. The absence of symptoms is not necessarily indicative of safe conditions.

Acute Toxicity Values: Silica: LD50 oral rat >22,500 mg/kg.

Skin Sensitization: Not a skin sensitizer in animals or humans.

Repeated Dose Toxicity:

Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling and sometimes
fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific
chest illness and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with
silicosis are predisposed to develop mycobacterial infections (tuberculous and non-tuberculous) and fungal
infections. Inhalation of air with a very high concentration of respirable silica dust can cause the most
serious forms of silicosis in a matter of months or a few years. Some epidemiologic studies have
concluded that there is significant risk of developing silicosis even at airborne exposure levels that are
equal to the recommended NIOSH REL, and ACGIH TLV.

SDS No: 011-U-GHS
Page 6 of 8 Date Prepared: April 2015
Other Data with Possible Relevance to Human Health:

There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with
an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder
manifested by fibrosis of the lungs, skin and other internal organs) rheumatoid arthritis, systemic lupus,
erythematosus, sarcoidosis, chronic bronchitis, chronic obstructive pulmonary disease (COPD),
emphysema, chronic kidney disease and end-stage renal disease.

For further information consult "Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic
Society Medical Section of the American Lung Association, American Journal of Respiratory and Critical Care Medicine,
Volume 155, pages 761-768, 1997, and see also NIOSH Hazard Review – Health Effects of Occupational Exposure to
Respirable Crystalline Silica, April 2002 (see Section 7 for NIOSH Hazard Review Website).

Carcinogenicity: The International Agency for Research on Cancer has determined that crystalline silica is carcinogenic to
humans (Group 1 - carcinogenic to humans). Refer to IARC Monograph 100C, A Review of Human Carcinogens: Arsenic,
Fibres, and Dusts (published in 2011) in conjunction with the use of these materials. The National Toxicology Program
classifies respirable crystalline silica as "known to be a human carcinogen". Refer to the Twelfth Report on Carcinogens
(2011). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a
suspected human carcinogen (A2).

Developmental / Reproductive Toxicity: No specific data is available, however, there is no evidence that silica exposure
has any effect on reproduction.
