SECTION V 鈥? HEALTH HAZARDS
SUMMARY: Flux-calcined diatomaceous earth (Kieselguhr) contains crystalline silica which is a known cause of silicosis, a progressive, sometimes fatal
lung disease. In a 1997 monograph (Volume 68, 鈥淪ilica, Some Silicates, Coal Dust and Para-Aramid Fibrils鈥?), the International Agency of Research on
Cancer (IARC) has classified 鈥渋nhaled crystalline silica from occupational sources鈥? in Group 1 as a substance 鈥渃arcinogenic to humans.鈥? In making the
overall evaluation, the IARC Working Group noted that carcinogenicity in humans was not detected in all industrial circumstances studied. Although the
recent IARC determination was, in part, based on a 1992 study of diatomite workers, a 1996 follow up which was issued by the University of Washington
and Tulane University was not available to the Working Group. The follow up study reported a Standardized Mortality Ration (SMR) of 2.01 for non-
malignant respiratory disease (NMRD) and a SMR of 1.29 for lung cancer when compared to national and regional populations. This is a reduction of the
levels reported in the 1992 report (SMR=2.59 for NMRD and SMR=1.43 for lung cancer.)

As noted in the 1992 study, relatively intense exposures to crystalline silica that occurred before the 1950s were probably the most important contributors
in the excesses in NMRD and lung cancer. The 1996 report continues to support the conclusion that recent improvements in dust control in the industry
appear to have abated any excess risk in silicosis or lung cancer in today鈥檚 work environment. In 1997 a radiographic study was published by Tulane
University researchers that reported X-ray opacities of the post-1950 hires that were 鈥溾?onsistent with the prevalences observed in many unexposed
populations.鈥? These findings appear to be consistent with, and supportive, of current occupational exposure limits for cristobalite. A more detailed report
discussing the IARC classification and the diatomite worker studies is available upon request.

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE
Pre-existing diseases of the upper respiratory tract and lung such as bronchitis, emphysema, and asthma

SECTION V 鈥? HEALTH HAZARDS CONT鈥橠
ROUTE OF ENTRY: Inhalation (Chronic) TARGET ORGANS: Lungs

EFFECTS OF ACUTE EXPOSURE TO PRODUCT: Upper respiratory irritant 鈥? May cause coughing or throat irritation.

EFFECTS OF CHRONIC EXPOSURE TO PRODUCT:

Inhalation of crystalline silica dust in excess of the Threshold Limit Value (TLV) recommended by the American Conference of Governmental Industrial
Hygienists (ACGIH) or in excess of the Permissible Exposure Limit (PEL) established by OSHA over an extended number of years may cause silicosis, a
progressive sometimes fatal lung disease. Although silicosis is a non-cancerous lung disease, a 1992 study conducted by the University of Washington on
certain diatomite workers, and a 1996 follow-up to this study indicates that exposure to high concentrations of crystalline silica for many years may
increase the potential risk of developing lung cancer. The 1996 follow-up study continues to support the findings of the 1992 study in that for those
workers hired since 1960, no increase in lung cancer mortality risk was found. Consequently, maintenance of crystalline silica dust concentrations at or
below levels specified by occupational standards setting agencies will minimize, if not eliminate, any potential excess risk of NMRD or lung cancer.

IARC - 鈥淚nhaled crystalline silica from occupational sources鈥? 鈥? Group 1 鈥? Carcinogenic to humans
NTP - 鈥淪ilica, crystalline (respirable)鈥? 鈥? 鈥渒nown to be a human carcinogen鈥?
OSHA - Has not classified crystalline silica as a carcinogen

CHEMICAL STABILITY:
INCOMPATIBILITY TO OTHER SUBSTANCES YES X NO
IF YES, WHICH ONES? Hydrofluoric Acid
YES X NO
Products containing Silica may react violently with Hydrofluoric Acid

REACTIVITY AND UNDER WHAT CONDITIONS: Not Applicable HAZARDOUS DECOMPOSITION PRODUCTS: Not Applicable

SECTION VII 鈥? PRECAUTIONS FOR SAFE HANDLING AND USE
PERSONAL PROTECTIVE EQUIPMENT:

Respirators fitted with filters certified to standard 42CFR84 under series N95 should be worn when dust is present. If the dust concentration is less than
ten (10) times the Permissible Exposure Limit (PEL) use a quarter or half-mask respirator with a N95 dust filter or a single use dust mask rated N95. If
dust concentration is greater than ten (10) times and less than fifty (50) times the PEL, a full-face piece respirator fitted with replaceable N95 filters is
recommended. If dust concentration is greater than fifty (50) and less than two hundred (200) times the PEL use a power air-purifying (positive pressure)
respirator with a replaceable N95 filter. If dust concentration is greater than two hundred (200) times the PEL use a type C, supplied air respirator
(continuous flow, positive pressure), with full face piece, hood or helmet.

GLOVES: Not normally necessary RESPIRATORY: Note Above EYE: Goggles to protect from dust

FOOTWEAR: Not necessary CLOTHING: Not normally necessary

ENGINEERING CONTROLS (E.G. VENTILATION, ENCLOSED PROCESS): Local 鈥? Control within recommended TLV/PEL. Refer to ACGIH
publication "Industrial Ventilation鈥? or similar publications for design of ventilation systems.

LEAK AND SPILL PROCEDURE: Vacuum clean spillage, wet sweep or wash away. Avoid creating dust.
WASTE DISPOSAL: Non-Biodegradable. Use solid waste disposal common to landfill type operations or in slurry to sumps. Not considered a
hazardous waste under RCRA (4OCFR Part 261).

HANDLING PROCEDURES: Avoid creating dust. Repair or properly dispose of broken bags.

STORAGE REQUIREMENTS: Store in a dry place to maintain product quality.

SPECIAL SHIPPING INSTRUCTIONS: None

SECTION VIII 鈥? FIRST AID MEASURES
SKIN: Not absorbed by the skin. May cause dryness. Use moisture renewing lotions if dryness occurs.

EYE: May cause irritation or inflammation. Wash with generous quantities of water. Consult physician if irritation persists.

INHALATION: Acute inhalation can cause dryness of the nasal passages and congestion of the upper respiratory tract. Remove to fresh air.

INGESTION: Short-term exposure not considered harmful. Drink generous amounts of water to reduce bulk and drying effects.
