Safety Data Sheet
Chrome Crystals
General advice Consult a physician. Show this safety data sheet to the doctor in attendance.
Move out of dangerous area.
If inhaled IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
IMMEDIATELY call a physician and be prepared to transport the victim to a
hospital even if no symptoms (such as wheezing, coughing, shortness of
breath, or burning in the mouth, throat, or chest) develop. Provide proper
respiratory protection to rescuers entering an unknown atmosphere.
Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be
used; if not available, use a level of protection greater than or equal to that
advised under Respirator Recommendation.
In case of skin contact IMMEDIATELY flood affected skin with water while removing and isolating all
contaminated clothing. Gently wash all affected skin areas thoroughly with
soap and water. IMMEDIATELY call a hospital or poison control center even
if no symptoms (such as redness or irritation) develop. IMMEDIATELY
transport the victim to a hospital for treatment after washing the affected
areas.
In case of eye contact First check the victim for contact lenses and remove if present. Flush victim's
eyes with water or normal saline solution for 20 to 30 minutes while
simultaneously calling a hospital or poison control center. Do not put any
ointments, oils, or medication in the victim's eyes without specific instructions
from a physician. IMMEDIATELY transport the victim after flushing eyes to a
hospital even if no symptoms (such as redness or irritation) develop.
If swallowed Some heavy metals are VERY TOXIC POISONS, especially if their salts are
very soluble in water (e.g., lead, chromium, mercury, bismuth, osmium, and
arsenic). IMMEDIATELY call a hospital or poison control center and locate
activated charcoal, egg whites, or milk in case the medical advisor
recommends administering one of them. Also locate Ipecac syrup or a glass
of salt water in case the medical advisor recommends inducing vomiting.
Usually, this is NOT RECOMMENDED outside of a physician's care. If
advice from a physician is not readily available and the victim is conscious
and not convulsing, give the victim a glass of activated charcoal slurry in
water or, if this is not available, a glass of milk, or beaten egg whites and
IMMEDIATELY transport victim to a hospital. If the victim is convulsing or
unconscious, do not give anything by mouth, assure that the victim's airway
is open and lay the victim on his/her side with the head lower than the body.
DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a
hospital.
Personal protective equipment for first-aid responders
See section 8
4.2 Most important symptoms/effects, acute and delayed
Dermal contact can cause primary irritation as well as ulceration and allergic eczema. Inhalation can cause nasal
irritation and septal perforation. Pulmonary irritation, bronchogenic carcinoma may result from inhalation of
chromate dust. Ingestion causes violent gastroin- testinal irritation with vomiting and diarrhea.
SECTION 5: Fire-fighting measures

Dike area and do not allow runoff to enter any waterways or sewer.
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting. Strong oxidizing agent.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid all contact. Avoid breathing vapours, mist or gas. Ensure adequate
ventilation. Evacuate personnel to safe areas. For personal protection see section 8.
6.2 Environmental precautions
Material is extremely hazardous to the environment. Do not allow product to enter waterways or sewer. Do not flush
residue to sewer.
6.3 Methods and materials for containment and cleaning up
If you spill this chemical, you should dampen the solid spill material with water,then transfer the dampened material
to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your
contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all
contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer
(or other responsible person) has verified that the area has been properly cleaned.
SECTION 7: Handling and storage
7.1 Precautions for safe handling
Avoid all contact. Wear protective equipment whenever handling or using product. Refer to section 8. Do not eat,
drink or smoke after using this material without vigorous hand washing. Inspect clothing after use and dispose if
contaminated. Material is hydroscopic.
7.2 Conditions for safe storage, including any incompatibilities
Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully
resealed and kept upright to prevent leakage. Avoid strong acids, oxidizers and flammable materials. Substance is
a strong oxidizer.

Face shield and safety glasses. Use equipment for eye protection tested and approved under appropriate
government standards such as NIOSH (US) or EN 166(EU).
Skin protection
*MINIMUM PROTECTIVE CLOTHING: If Tyvek-type disposable protective clothing is not worn during handling of
this chemical, wear disposable Tyvek-type sleeves taped to your gloves. *RECOMMENDED GLOVE MATERIALS:
Recommended Glove Type For Use With Neat (Undiluted) Chemical: Recommendations based on permeation test
results are made for handling the neat (undiluted) chemical. If this chemical makes direct contact with your glove, or
if a tear, puncture or hole develops, replace them at once. Suggested Glove Type(s) (RAD): No information
available
Body protection
Complete suit protecting against chemicals, The type of protective equipment must be selected according to the
concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection
*RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH- approved
half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas
and SO2) with a dust/mist filter.
Environmental exposure controls
