What we do

Hazardous Chemical Agents

Following assessment of risk from exposure to Hazardous Chemicals Agents (HCA) from production processes or cleaning activities, HCA typically become airborne and can be breathed by employees and other exposed persons.

We assist in determining the level of exposure which is compared with Occupational Exposure Limits pertaining to the relevant HCA measured, to confirm compliance to the OHS Act, Hazardous Chemical Agents Regulation 6.


Lead can be ingested when eating a meal with hands contaminate with products that contain lead, inhaled during work processes, or from handling such materials with bare hands.

Between skin absorption, ingestion and Inhalation, the latter causes the highest level of exposure as relatively much more lead is absorbed into the body through breathing dust or fume containing lead.

Following assessment of risk indicating a potential for lead exposure, the level of exposure to airborne lead of employees must be determined and compared with Occupational Exposure Limits to ascertain compliance to the OHS Act, Lead Regulation 7.


South Africa, a country where asbestos mining occurred on a competitive level in the international arena, of the six types of asbestos present as natural resources, only three are deemed to be of major concern in the building and construction industry today.

These include white, brown and blue asbestos. The incredible versatility and durability of asbestos as mineral, and thus an excellent building product additive, resulted in asbestos to be added as to a multitude of building materials and products. Asbestos containing materials were thus very popular in the past, hence private owners, business owners, users of rental buildings and e.g. demolition companies, therefore are at risk of exposure to asbestos dust during residence or occupation, maintenance and or removal activities.

Following assessment of risk, we determine the level of exposure through scientific methodology and results are compared with Occupational Exposure Limits to confirm compliance with the OHS Act, Asbestos Abatement Regulations, 2020, regulation 16.

*All assessment and measurement results are interpreted and compared with National Standards (or International Standards where relevant).


Air Monitoring (or air sampling) when done correctly, help to confirm the level of exposure to airborne asbestos dust using local and international scientific methods and procedures.
