• Number of samples taken and analysed;

• Composition of dust;

• Concentration of the constituents; and

SILICA DUST DATA COLLECTION GUIDING DOCUMENT

1. PURPOSE

The Department of Labour has reduced the occupational exposure limit of silica crystalline respirable dust from 0.4 mg/m³ to 0.1 mg/m³. There is presently no system in place for the industry to report to the Department of Labour whether industries comply with the new occupational exposure limit. The purpose of collecting silica exposure compliance information will enable the DOL to collect the following information—

(a) National Profile of all the industries that have the potential to expose the employees to respirable silica dust;

(b) To determine the level of exposure to respirable silica dust;

(c) Number of employees exposed;

(d) The AIA performing the monitoring and evaluation.

2. REPORTING MECHANISM

The data must be sent directly to Head Office via e-mail to:

Jabu.Mhlophe@labour.gov.za.

3. SAMPLING

Sampling must be done according to the national and international recognised standards.

4. FREQUENCY OR REPORTING

Data must be sent on the 31 July and 31 January of every year.

[Submission of crystalline silica dust air monitoring reports am from bi-annual to annual reporting by GoN R408 in G. 36548.]

5. CONFIDENTIALITY

All information received will be confidential and it will not be shared with any other person or entity, except with the written consent from the company concerned.
