SILICA CRYSTALLINE - QUARTZ

WARNING:

For inhalation exposure ONLY: This substance has been classified by the IARC as Group 1:

CARCINOGENIC TO HUMANS

The International Agency for Research on Cancer (IARC) has classified occupational exposures to

respirable

(<5 um) crystalline silica as

being carcinogenic to humans . This classification is based on what IARC considered sufficient evidence from epidemiological studies of

humans for the carcinogenicity of inhaled silica in the forms of quartz and cristobalite. Crystalline silica is also known to cause silicosis, a

non-cancerous lung disease.

Intermittent exposure produces; focal fibrosis, (pneumoconiosis), cough, dyspnoea, liver tumours.

STYRENE

The material may cause skin irritation after prolonged or repeated exposure and may produce a contact dermatitis (nonallergic). This form of

dermatitis is often characterised by skin redness (erythema) and swelling the epidermis. Histologically there may be intercellular oedema of

the spongy layer (spongiosis) and intracellular oedema of the epidermis.

WARNING:

This substance has been classified by the IARC as Group 2B: Possibly Carcinogenic to Humans.

For silica:

The literature on the fate of silica in the environment concerns dissolved silica in the aquatic environment, irrespective of its origin

(man-made or natural), or structure (crystalline or amorphous). Indeed, once released and dissolved into the environment no distinction

can be made between the initial forms of silica. At normal environmental pH, dissolved silica exists exclusively as monosilicic acid

[Si(OH)4]. At pH 9.4 the solubility of amorphous silica is about 120 mg SiO2/l .

Product / Packaging disposal

DO NOT

allow wash water from cleaning or process equipment to enter drains.

It may be necessary to collect all wash water for treatment before disposal.

In all cases disposal to sewer may be subject to local laws and regulations and these should be considered first.

Where in doubt contact the responsible authority.
