SECTION III 鈥? HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Malvern Minerals Co. silica is white to light gray in color and is in a powder form. It is not
known to be environmentally hazardous. The silica is chemically inert and is a non-
combustible mineral. Excessive and long-term exposure to silica dust may cause lung
disease or silicosis.
When crystalline silica is heated to more than 870潞C it forms trydimite. Crystalline silica
heated over 1470潞C the can change to cristobalite. The OSHA PEL for crystalline silica as
trydimite and cristobalite is one-half of the OSHA PEL for crystalline silica (quartz).
HEALTH HAZARDS
Potential Health Effects Through Inhalation
1. Silicosis Respirable crystalline silica can cause a scarring of the lungs
(fibrosis) known as silicosis. Symptoms include cough, shortness
of breath, wheezing and reduced pulmonary function. The disease
may be aggravated by smoking. Silicosis may be progressive and
may lead to disability and death.
2. Cancer Crystalline silica (quartz), inhaled from occupational sources, is
considered a carcinogenic to humans. Refer to IARC Monograph
68, Silica, Some Silicates and Organic Fibers (published in June鈥?97)
3. Nephrotoxicity There are some studies that show an increased occurrence
of chronic kidney disease and end-stage renal disease in workers exposed
to excessive respirable crystalline silica.
4. Autoimmune Diseases There are several studies an increased frequency of
contracting scleroderma and other connective tissue disorders in workers
exposed to respirable crystalline silica.
5. Tuberculosis Silicosis increases the risk of tuberculosis.
OTHER
Skin Contact No adverse effects
Eye Contact Crystalline silica may cause irritation and possible abrasion to the
Cornea.
Ingestion Not applicable.
Chronic Effects Silicosis, cancer, autoimmune diseases, tuberculosis. and nephro-
toxicity are all chronic effects.
Signs and Symptoms of Exposure There are generally no signs or symptoms of
exposure to crystalline or silica.
SECTION IV 鈥? FIRST AID MEASURES
Gross Inhalation Remove victim to fresh air, give artificial respiration as needed, seek
medical attention as needed.
Eye Contact Flush eyes immediately with water. If irritation continues, seek
medical attention.
Skin Contact Wash exposed skin with soap and water.
Ingestion N/A
Medical Conditions Aggravated by Exposure: Conditions of individuals with lung
disease can be aggravated by exposure to respirable silica (quartz).
SECTION V 鈥? FIRE FIGHTING MEASURES
Crystalline silica, in the form of quartz, is not flammable, combustible or explosive.
SECTION VI 鈥? ACCIDENTAL RELEASE MEASURES
Spills Use dustless methods (HEPA vacuum or wet method). Do not sweep. Wear
protective equipment specified in Section XIII.
SECTION VII 鈥? HANDLING AND STORAGE
Precautionary Measures Do not breath dust. Use adequate ventilation and proper
dust collection. Maintain and use proper, clean respiratory equipment. See
Sec. VIII for proper respiratory equipment. Be careful with bags or
containers to prevent spills or damage to bags. Do not use as a dry abrasive
blasting agent. Use good housekeeping in storage areas and keep dust off of
floor, bags and rafters. Employees that are handling micro silica (quartz)
need to be trained in accordance with State and Federal regulations.
IN CASE OF RESALE, BAGS AND CONTAINERS MUST HAVE APPROPRIATE WARNING
LABLES ATTACHED AND POSTED AS TO MSHA AND OSHA PRECAUTIONS AND
REGULATIONS. PROVIDE PROPER TRAINING FOR YOUR EMPLOYEES.

SECTION VIII 鈥? EXPOSURE CONTROL/PERSONAL PROTECTION
Ventilation Use sufficient exhaust to maintain exposures below occupational
exposure limits (PEL). See ACGIH 鈥? Industrial Ventilation. A Manual of
Recommended Practice鈥?
Respiratory Protection Use appropriate respiratory protection as covered in
The most recent standards of ANSI (Z88.2), OSHA (29 CFR 1910.134, MSHA
(30 CFR Parts 56 and 57) and NIOSH Respirator Decision Logic.
Gloves Recommended
Eye Protection Safety glasses or goggles are recommended
