|
SPECIAL FIRE FIGHTING PROCEDURES
|
|
If this material is involved in a fire-fighting task, use a full-face, air -supplied, positive
pressure respiratory device to protect against exposure to hydrogen halogen and
fumes of halogen salts.
|
UNUSUAL FIRE AND EXPLOSION HAZARDS
|
|
No unusual fire or explosion hazards are associated with this material.
|
|
This product is a stable material.
|
INCOMPATIBILITY (MATERIALS TO AVOID)
|
|
Contact with acids liberates hydrogen halogen gas that is toxic and corrosive.
|
HAZARDOUS DECOMPOSITION PRODUCTS
|
|
During melting operations and at elevated temperatures, various fluoride compounds
will be liberated including, but not limited to hydrogen halogen. Toxic fumes of Na2O
will also be emitted.
|
VI. HEALTH HAZARD INFORMATION
|
PRIMARY ROUTE(S) OF EXPOSURE
|
|
INHALATION: Inhalation halogen may result during blending, mixing, melting, pouring, crushing or grinding operations which
generate airborne particulate during use of this metal.
INGESTION: Hand, clothing and drink contact with halogen salts, dust or fume can cause ingestion of particulate during hand to
mouth activities such as eating, drinking, smoking, nail biting, etc.
SKIN: Skin contact with fluoride salts can cause irritation, redness, swelling of tissue and permanent scarring or disability.
EYES: Particulate halogen salt dust or fume can cause severe burning and swelling to the eye and surrounding tissue. Airborne
particulate is always a problem as well as inserting fingers into the eye socket if the hand or clothing is contaminated with halogen
salts.
|
|
Exposure to the dust or fume of halogen salts may present significant health hazards. Halogen salts can cause acute poisoning or
death (principally by ingestion). Skin contact and exposure to mucous membranes can cause severe irritation and tissue damage.
Nose bleeds and slow healing scars in the nasal passage have been reported. Crippling bone changes and mottling of tooth
enamel are chronic effects of exposure although they are not common among current industrial employees.
|
|
ACUTE: Ingestion halogen salts can cause severe gastric pain, internal bleeding, tissue damage and death. Acute poisoning
from inhalation is not common. Nose bleeds, skin irritation, eye irritation, tissue damage and slow healing scars can result if
exposure is excessive. Halogen salts are soluble in the body fluids and sweat and are corrosive to the skin and mucous
membrane.
CHRONIC: Chronic exposure to halogen compounds has been reported to cause a calcification of bone and ligaments known as
osteosclerosis (hardening of the bone due to deposition of halogen) and mottling of tooth enamel although neither effect is
common in industrial populations. Prolonged exposure to halogen salts may cause damage to the skin, eye and mucous
membranes
|
|
The National Toxicology Program, International Agency, lists neither this product nor its ingredients as a carcinogen for Research
on Cancer or United States Occupational Safety and Health Administration.
|
MEDICAL CONDITIONS AGGRAVATED BY
EXPOSURE
|
|
Persons with pre-existing eye and skin disorders or damage to mucous membranes may be more susceptible to the effects of
halogen exposure. Becausehalogen salt and fume can be a respiratory irritant and has been linked to skeletal abnormalities and
gastric complications, proper screening or examinations should be conducted on individuals who may be exposed to further risk if
handling and use of this material causes excessive exposure.
|
VII. INDUSTRIAL HYGIENE CONTROL MEASURES
|
|
Local exhaust ventilation should be used to control exposure to airborne halogen compounds whenever possible.
|
|
Use NIOSH approved respirators as specified by an industrial Hygienist or qualified Safety Professional. Lung function tests are
recommended for users of negative pressure devices.
|
|
Wear gloves to prevent hand contact with halogen compounds. Gauntlet-type gloves are recommended and, where halogen
containing solutions or acids are used, the gloves should be acid resistant.
|
|
Wear safety glasses, chemical goggles (plastic lens) or full-face shield when handling halogen compounds. Do not wear contact
lenses.
|
OTHER PROTECTIVE EQUIPMENT
|
|
Protective clothing such as uniforms, disposable coveralls, safety shoes, etc. may be required during handling operations as
appropriate to the circumstances of exposure. For increased protection it may by advisable to wear acid resistant jacket, boots,
trousers, etc. as appropriate.
|
RECOMMENDED MONITORING
PROCEDURES
|
|
ENVIRONMENTAL SURVEILLANCE:
Exposure to the elements identified in
Section II can be best determined by
having air samples taken in the
employees breathing zone, work area
or department.
|
MEDICAL SURVEILLANCE: Lung function tests, chest x-rays and routine physical
examination may be useful to determine effects of dust or fume exposure.
|
IX. ENVIRONMENTAL PROTECTION INFORMATION
|
STEPS TO BE TAKEN IF MATERIAL IS
RELEASED OR SPILLED
|
|
If the DesofinTM compound is spilled from its containing capsule, clean-up should be conducted with a vacuum system utilizing a
high efficiency particulate air filtration system. Caution should be taken to minimize airborne generation of powder or dust and
avoid contamination of the air and water. Spills of halogen containing solutions or acids should be neutralized by careful additions
of lime slurry, soda ash or other alkali. Small amounts may be treated by using excess water to reduce acidity. Caution must be
taken during neutralization to avoid exposure to halogen gases or other halogen compounds generated.
|
|
State or federal regulations may require specific labeling, packing, storage, transportation and disposal procedures. Contact an
Environmental Engineer or consultant familiar with waste disposal regulations.
|
|
Halogen compounds may have significant impact on air and water quality. airborne emissions, spills and releases to the
environment (discharge to streams, sewer systems, ground water, surface soil, etc.) should be controlled immediately. If such
potential for a spill or release exists it is advisable to develop an emergency spill response plan. It is also advisable to consider
monitoring ambient air as well as any effluent which may contain fluorides if potential exists for damage to aquatic or terrestrial
ecosystems.
|
X. SPECIAL PRECAUTIONS
|
|
This product must be handled accordingly to the size, shape and quantity of material involved. Drums may require use of hoists,
cranes, etc. Powder or liquid handling should be conducted to minimize employee contact and spill release potential. Wash hands
prior to eating or smoking.
|
|
Store this product in a dry area. Do not store adjacent to acids. Keep away from contact with food or food products.
|
ADDITIONAL INFORMATION
|
DesofinTM Brand Grain Refining Compound
Safety to Mankind and Our Environment:
DesofinTM as a non-hazardous formulation of chemicals which are encased in a non porous sealed aluminum metal case
and no powder is handled by a user. This USA Trade Marked product called DesofinTM was tested by the German EPA in
1976 in Lahr, Germany at the ITT Grohe Faucet Gmbh. This test was designed by the German EPA to measure the quantity
of halogens emitted to the atmosphere in the chimney exit of the Baghouse which filtered out ash and metal oxides (like zinc
oxide) and was measured three times and there was never more than one PPM (part per million) of halogen gases.
This non-hazardous chemical combination was only possible by addition of a caustic chemical(s) used to prevent escape of
halogen hazardous gases which attacks the ionosphere.
DesofinTM has been sold worldwide since 1983 without a tragic occurence in the use of this grain refiner and deoxidizer of
copper and aluminum alloys.
