Rating (Scale 0-4): Not applicable
Component CAS # Appr % ____________________________________________________________ Chromium 7440-47-3 100%
Emergency Overview:
In the as-received form, very little is present in the form of dust. However, if this
material is ground down into a dust, then the dust can be irritating. Laboratory tests
indicate that in the dust form, this material can be carcinogenic. This product contains
a material known to the State of California (USA) to cause cancer.
Physical state: Silver-gray powder or granules
Potential health effects (overview):
The material in either solid or alloy form is generally not considered
hazardous. However, if the process involves grinding, melting, cutting,
or any other process that causes a release of fumes, hazardous levels
of airborne particulates could be generated.
Symptoms of exposure:
Exposure to chromium dust by inhalation, skin contact or by eye can cause
irritation.
Primary routes of entry:
Inhalation, skin contact, eye
Human effects and symptoms of exposure:
Listed below are certain potential health hazards which apply to the hazardous
ingredients found in the subject alloy(s) when present in the dust form:
Chromium: Generally toxic especially in the dust form
Skin: May cause contact dermatitis.
Eye: Will cause irritation
Medical Conditions Aggravated by Exposure:
Individuals who may have had allergic reactions to metals or
sensitivity, may encounter skin rash or dermatitis, if skin
contact with this product, in the dust form, occurs. Persons
with impaired pulmonary functions, may incur further impairment
if dust or fumes (as a result of high temperature processing)
are inhaled.
Carcinogenic references:
Considered to be a proven carcinogen in humans. Warning: This
product contains a chemical known to the State of California (USA)
to cause cancer.
First Aid for Eyes:
Dust or powder should be flushed from the eyes with running water
for 15 minutes. If irritation persists obtain medical assistance.
First Aid for Skin:
Skin cuts and abrasions can be treated by standard first aid.
Skin contamination with dust or powder can be removed with soap
and water. If irritation persists obtain medical assistance.
First Aid for Inhalation:
Breathing difficulty, caused by inhalation of dust or fume
requires removal to fresh air. If breathing has stopped
perform artificial respiration and seek medical assistance
at once.
First Aid for Ingestion:
If conscious, give water and induce vomiting immediately as directed by
medical personnel. Never give anything by mouth to an unconscious person.
Flash Point.................... Non-flammable as a solid Flammable Limits in Air........ Flammable limit in air, % by vol. LEL (Lower Explosive Limit): Not Applicable UEL (Upper Explosive Limit): Not Applicable Fire Extinguishing Media: This material is non-combustible. Use appropriate extinguishing agent for surrounding fires. Do not use water to extinguish fires around operations involving molten metal, due to the potential for a steam explosion. Use dry powder, sand, or water fog. Firefighting Procedure: Self-contained breathing apparatus should be worn when fighting metal dust fires. High levels of dust or fine particles in the air may ignite or explode. Do not use CO2 because fine dust of this material may explode in an atmosphere of CO2. Fire and explosion hazards: This is a stable material and will not burn or ignite.
Spill Response: Because it is a non-renewable resource, this material should be reclaimed when possible. Disposal considerations: Because it is a non-renewable resource, this material should be reclaimed when possible. When reclaiming is not feasible and disposal the only alternative, then it should be done in accordance with all applicable federal, state, and local regulations.
In solid and as-received form, this material poses no special problems. Store metal in a dry area. Do not store adjacent to acids.
Eye Protection Requirements:
Safety glasses are recommended.
Skin Protection Requirements:
Protective Neoprene® gloves are recommended, to prevent mechanical
irritation.
Respiratory Protection:
Use an appropriate NIOSH approved respirator if airborne
dust concentrations exceed the PEL or TLV. Try to avoid
creating dust conditions.
Other protective equipment:
Eye wash fountain should be readily available in areas of use of
handling. Handle only with gloves, Neoprene® is recommended.
Safety glasses with side shields should be worn at all times, especially when
being exposed to the dust of this product.
Exposure Limits:
Not established for product as a whole. Refer to Section 02 above.
Ventilation Requirements:
Local exhaust: Recommended, when cutting, grinding, or
melting or any other operation where dust or fumes are created.
Environmental Surveillance:
If the operation generates dust or fumes, exposure to airborne
materials should be determined by having air samples taken in
the employee breathing zone and work area.

Stable: Yes Hazardous Polymerization: Does not occur. Hazardous Decomposition Products: None under proper use conditions Conditions to avoid: Conditions that could create dust or fumes. Note that in a metallography laboratory where these granules might be polished for examination, if the polishing table and media should dry out, there could be created a dust hazard. Important to keep such polishing tables and media wet at all times and when the media is changed, it should be done when everything is wet to avoid creating a dust hazard. Materials to avoid: Basic incompatibilities are acetylene, ammonia and strong oxidizers.

Human effects and symptoms of exposure:
Listed below are certain potential health hazards which apply to
the hazardous ingredients found in the subject alloy(s) when present
in the dust form:
Chromium: Generally toxic expecially in the dust form
Skin: May cause contact dermatitis.
Eye: Will cause irritation
Medical Conditions Aggravated by Exposure:
Individuals who may have had allergic reactions to metals or
sensitivity, may encounter skin rash or dermatitis, if skin
contact with this product, in the dust form, occurs. Persons
with impaired pulmonary functions, may incur further impairment
