2 of 8Section III. Hazards Identification
Classification

These products are not dangerous preparations according to Directive
1999/45/EC

Potential Adverse Human
Health Effects

These products may generate dust during handling and use. As any natural
occurring mineral, attapulgite may contain quartz (crystalline silica). Long term
overexposure to crystalline silica dust may cause silicosis. These products,because of their coarse particle size, has very low respirable fraction and thecontent in respirable crystalline silica is negligible.

Target Organs

Eyes and Skin (irritation risk). Pulmonary System (irritation and chronic risk).

Protective Measures

In case of exposure to high level of airbone dust, it is recommended the use ofsafety glasses and approved dust respirator.
Use in well ventilated areas. Avoid breathing dust and contact with eyes. It isrecommended the use of latex or chemical resistant gloves in handling.

Section IV. First Aid Measures

persists.

Ingestion

Provide symptomatic treatment and seek medical attention.

SYMPTOMS AND EFFECTS

Section VIII. Exposure Controls/Personal Protection
Respect regulatory provisions for dust (inhalable and respirable). These products
have no specific Occupational Exposure Limit (OEL). A non-intentionalsubstance (quartz) in the composition of these products has not community OEL
but in some Member States are regulated as follows:

Exposure Limit Values(for Respirable Crystallinesilica)(mg/m3), (January, 2006)

Austria: 0,15 (Maximale Arbeitspaltz Koncentration)
Belgium: 0,1Denmark: 0,1 (Threshold Limit Value)
Finland: 0,2 (Occupational Exposure Standard)
France: 0,1 (Valeur limite de Moyenne d’Exposition)
Germany: There are no OELs for crystalline silica since 2005; instead of an
OEL there is a workers health protection system
Greece: 0,1 (Legislation for mining activities)
Ireland: 0,05 (2002 Code of Practice for the Safety, Health & Welfare at Work)
Italy: 0,05 (Threshold Limit Value)
Luxemburg: 0,15 (Grenzwert nach TRGS 900)
The Netherlands: 0,075 (Maximaal Aanvarde Concentratie)
Norway: 0,1 (Administrative Nomer (8hTWA) for Forurensing I Arbeldsmilljöet)
Portugal: 0,1 (Threshold Limit Value)
Spain: 0,1 (Valores límite, INSHT)
Sweden: 0,1 (Yrkeshygieniska Gränsvärden)
Switzerland: 0,15 (Valeur limite de Moyenne d’Exposition)
United Kingdom: 0,3 (Workplace Exposure Limit, HSE)
General ventilation

Exposure Controls

Local exhaust ventilation is recommended to keep airborne dust levels below
exposure limits.

Respiratory: Use air-purifying dust respirator if airborne dust concentration isabove exposure limits.

Personal Protection

Hands: No special hands protection is required in normal conditions but the useof gloves is recommended.
Skin: No special skin protection is required in normal conditions. Wash skin if
mechanical irritation is experienced.
Eyes: Use safety glasses with side shields if large amounts of product that could
generate dust is handled.

Industrial Hygiene

Wash hands and other exposed areas with mild soap and water before eating,drinking, smoking and when leaving work. Keep the working area as clean andtidy as possible.

Additional Remarks

No additional remarks.

EFFECTS OF CHRONIC OVEREXPOSURE
Main Effects

Individual particle length of this attapulgite is shorter than 5µm. IARC has classified
attapulgite dust (fibres below 5µm) as class 3 ("Cannot be classified as tocarcinogenicity to Humans).
As any natural occurring mineral, attapulgite may contain quartz (crystalline silica).
In 1997, IARC concluded that the respirable fraction of crystalline silica inhaledfrom occupational sources can cause lung cancer in humans. However, it pointed outthat not all industrial circumstances, nor all crystalline silica types, were to beincriminated (IARC Monographs, Vol 68)
In June 2003, the EU Scientific Committe on Occupational Exposure Limits(SCOEL) concluded that the main effect in humans of the inhalation of respirable
crystalline silica dust is silicosis. “There is sufficient information to conclude that therelative risk of lung cancer is increased in persons with silicosis. Therefore
preventing the onset of silicosis will also reduce the cancer risk…”. (SCOEL SUM
Doc 94-final, July 2003)

Other Effects

No mutagenic, teratogenic or developmental toxicity effects are known

Additional Remarks

There is body of evidence supporting the fact that increased cancer risk would be
limited to people already suffering from silicosis. According to the current stateof the art, worker protection against silicosis can be consistently assured byrespecting the existing regulatory occupational exposure limits.
