The chromate experts

Occupational and environmental protection

Carcinogenic chromium (VI) compounds (chromates) in the workplace endanger the smooth operation of every company!

The manufacturers of CHP engines in particular warn their customers about the release of calcium chromate (CaCrO4) during maintenance and overhaul work on energy-generating systems (contact us if you do not have the warning messages - we will be happy to provide them to you).

These warnings are not issued without reason, as the following images show, because there is a risk of exposure or the risk of absorbing the substances through the skin when handling removable insulating elements.


But air turbulence also occurs during regular operation; Yellowish dust, which is often calcium chromate, can be found throughout the engine area.

The chromate experts are your first point of contact for this problem, because the classification as "H350 - carcinogenic (carcinogenic 1 B)" with the simultaneous classification as "H410 - Very toxic to aquatic organisms with long-term effects" means that every engine compartment that is provided with insulation containing calcium , a workplace that is hazardous to health and this fact means that special measures resulting from the Hazardous Substances Ordinance (GefStoffV) must be initiated, including:


Risk assessment

Substitution testing

Technical measures

Organizational measures

Personal (protective) measures

Risk assessment


The risk assessment is a management tool and planning basis for operational organization and work processes. Appropriate measures can prevent operational disruptions, accidents and other health impairments. You can reduce staff downtime.

Substitution testing


Substitution testing obligation means determining whether hazardous substances with which employees come into contact can be replaced by less dangerous substances. According to the Hazardous Substances Ordinance (GefStoffV), a substitution test must always be carried out when employees may be exposed to particularly dangerous pollutants. In the case of carcinogenic substances, it must always be checked whether measures can be taken to minimize the risk of exposure, or at best even completely eliminate it.
