Steps of Risk Management Phase

Hexavalent Chromium and Cadmium

Hexavalent Chromium and Cadmium

Hexavalent chromium and cadmium

are used in automotive coatings

Used as a color pigment and as a

corrosion inhibitor

Emitted as metal particulates

Why Control Hexavalent Chromium ?

Why Control Hexavalent Chromium ?

Hexavalent chromium is one of the most

toxic compounds identified by ARB

Minimal emissions can lead to significant

risk

Removal of hexavalent chromium will

reduce the need for public notification and

risk reduction plans

What are the Current Restrictions on Hexavalent

Chromium?

What are the Current Restrictions on Hexavalent

Chromium? Some air districts have rules that reduce

hexavalent chromium emissions

SCAQMD prohibits the use of coatings

that contain hexavalent chromium

VCAPCD requires chromium-containing

coatings to be sprayed inside a spray booth

Feasibility of ProposalFeasibility of Proposal

Alternative coatings are readily available

and widely used

Surveys show minimal usage of coatings

containing hexavalent chromium and

cadmium
