4. First aid measures 

Eye contact : Get medical attention immediately. Immediately flush eyes with plenty of water for at 

least 15 minutes, occasionally lifting the upper and lower eyelids. 

Skin contact : In case of contact, immediately flush skin with plenty of water for at least 15 minutes 

while removing contaminated clothing and shoes. Wash clothing before reuse. Clean 

shoes thoroughly before reuse. Get medical attention immediately. 

Inhalation : Move exposed person to fresh air. If not breathing, if breathing is irregular or if 

respiratory arrest occurs, provide artiflcial respiration or oxygen by trained personnel. 

Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention 

immediately. 

Ingestion : Wash out mouth with water. Do not induce vomiting unless directed to do so by medical 

personnel. Never give anything by mouth to an unconscious person. Get medical 

attention immediately. 

Protection of first-aiders : No action shall be taken involving any personal risk or without suitable training. If it is 

suspected that fumes are still present, the rescuer should wear an appropriate mask or 

self-contained breathing apparatus. It may be dangerous to the person providing aid to 

give mouth-to-mouth resuscitation. Wear suitable protective clothing and gloves. 

Remove contaminated clothing and shoes. 

5. Fire-fighting measures

Extinauishing media 

Suitable : Use an extinguishing agent suitable for the sun•ounding fire. 

Not suitable : None known. 

Special exposure hazards : Promptly isolate the scene by removing all persons from the vicinity of the incident if 

there is a fire. No action shall be taken involving any personal risk or without suitable 

training. 

Hazardous thermal : carbon dioxide,carbon monoxide,phosphorus oxides,metal oxide/oxides 

decomposition products 

Special protective : Fire-fighters should wear appropriate protective equipment and self-contained breathing 

equipment for fire-fighters apparatus (SCBA) with a full face-piece operated in positive pressure mode. 

6. Accidental release measures 

Personal precautions : No action shall be taken involving any personal risk or without suitable training. 

Evacuate surrounding areas. Keep unnecessary and unprotected personnel from 

entering. Do not touch or walk through spilled material. Provide adequate ventilation.

6 . Accidental release measures 

Large spill : Move containers from spill area. Approach release from upwind. Dike spill area and do 

not allow product to reach sewage system or surface or ground water. Notify any 

reportable spi[I to authorities. (See section 12 for environmental risks and 13 for 

disposal information.) Vacuum or sweep up material and place in a designated, labeled 

waste container. Dispose of via a licensed waste disposa[ contractor. Note: see 

Section 1 for emergency contact information and Section 13 for waste disposal. 

7 . Handling and storage 

Handling : Put on appropriate personal protective equipment (see Section 8). Eating, drinking and 

smoking should be prohibited in areas where this material is handled, stored and 

processed. Workers should wash hands and face before eating, drinking and smoking. 

Do not get in eyes or on skin or clothing. Do not ingest. Use only with adequate 

ventilation. Empty containers retain product residue and can be hazardous. Do not 

reuse container. 

Storage : Store in accordance with local regulations. Store in a dry, cool and well-ventilated area, 

away from incompatible materials (see Section 10). Keep container tightly closed and 

sealed until ready for use. Containers that have been opened must be carefully 

resealed and kept upright to prevent leakage. Do not store in unlabeled containers. 

Use appropriate containment to avoid environmental contamination.

OSHA re ulatory actions. Although the 1989 levels have been vacated the 11th Circuit Court of Appea[s~ cr 

recommends that these lower exposure levels be observed as reasonable worker protection. ,

Recommended monitoring : If this product contains ingredients with exposure [imits, personal, workplace 

procedures atmosphere or biological monitoring may be required to determine the efFectiveness of 

the venti[ation or other control measures and/or the necessity to use respiratory 

protective equipment. Reference to national guidance documents for methods for the 

determination of hazardous substances will also be required. 

Engineering measures : Use only with adequate ventilation. If user operations generate dust, fumes, gas, vapor 

or mist, use process enclosures, local exhaust ventilation or other engineering controls 

to keep worker exposure to airborne contaminants below any recommended or statutory 

limits. 

Hygiene measures : Wash hands, forearms and face thoroughly after handling chemica[ products, before 

eating, smoking and using the lavatory and at the end of the working period. Ensure 

that eyewash stations and safety showers are close to the workstation location. Take 

ofP contaminated clothing and wash before reuse. 

Personal nrotection 

Respiratory : Use a properly fitted, air-purifying or air-fed respirator complying with an approved 

standard if a risk assessment indicates this is necessary. Respirator selection must be 

based on known or anticipated exposure levels, the hazards of the product and the safe 

working limits of the selected respirator. 

Hands : Chemical-resistant gloves.

to chemical safety goggles. 

Skin : Wear long sleeves and other protective clothing to prevent repeated or prolonged skin 

contact.

Crystalline silica as quartz is a component of this product. Prolonged inhalation of respirable crystalline quartz may cause 

delayed chronic lung injury - silicosis. Silicosis is a form of disabling pulmonary fibrosis which can be progressive and may 

lead to death. Silicosis may progress without further exposure to silica (Hathaway et al, 1991). Chronic inhalation of silica 

dust suppressed the immune response in mice (Scheuchenzuber et al, 1985), and a decreased immune response has 

also been shown in silicotics (Barlogova et al, 1981). The effect of silica on the immune mechanism may be mediated by 

its toxicity to pulmonary macrophages, a critical component of the immune response, and may have implications for the 

increased susceptibility of silicotics to respiratory infections, particularly tuberculosis. Inhaled crystalline silica particles 

induced several signs of pulmonary injury and inflammation in rats exposed to an airborne concentration of 50 mg/m3 for 6 

hours per day for 5 days (Driscoll et al, 1991). 

IARC (International Agency for Research on Cancer) rates crystalline silica as "carcinogenic to humans" (Group 1). The 

US NTP (National Toxicology Program) rates respirable crystalline silica as a"Proven Carcinogen". 

Silica has been inactive for inducing DNA damage in the B. subtilis rec assay (Kanematsu et al, 1980), chromosome 

damage or sister chromatid exchanges in hamster cells (Price-Jones et al, 1980), chromosome damage in human cells 

(Oshimura et al, 1984), in vitro oncogenic transformation of hamster cells into cancer cells (Oshimura et al, 1984), and 

induction of micronuclei in mouse bone marrow (Vanchugova et al, 1985). Crystalline silica has caused DNA strand 

breaks in vitro; etching the surface with hydrofluoric acid reduced this activity. 

At the time of this review, no reproductive studies were found for silica in humans. Few reproductive data are available for 

silica. As a component of welding fume, it caused infertility and fetal death in rats (Dabrowski et al, 1966). Intratracheal 

instillation of silica prolonged the estrus cycle in rats (Parsadanian, 1967). So-called "soluble silica" was tested for 

reproductive effects in rats, but the results were not available at the time of this review (Smith et al, 1973).
