Frequently asked questions
Answers to the questions we hear most often about chromium (VI), our services and the training course. Can’t find what you need? Get in touch.
General
What does The Chromate Experts UK do?
We help UK duty-holders find hexavalent chromium, remove it and prove it has gone — through on-site research and laboratory analysis, decontamination, substitution and compliant hazardous-waste disposal.
Where do you work?
On-site across Great Britain, with the same specialists from first sample to final certificate.
How quickly can you attend site?
Tell us about the plant and your concern and we will reply with the next step and an indicative timescale for an on-site assessment.
Do you provide documentation for compliance?
Yes. Every stage is documented, from laboratory results to waste-disposal records, so your COSHH and duty-of-care obligations are evidenced.
Chromium (VI)
What temperature does chromium (VI) form at?
Chromate compounds typically form above about 300 °C, where chromium-bearing steel meets high-temperature insulation containing calcium or sodium.
Is hexavalent chromium really a carcinogen?
Yes. Cr(VI) is classified as a category 1B carcinogen (H350, may cause cancer). Inhalation is linked to lung and nasal cancers, and skin contact can cause sensitisation and ulceration.
How do I know if my plant is affected?
The only reliable way is to test. We take on-site samples and breathing-air measurements and confirm the results in accredited laboratories.
What is the workplace exposure limit?
HSE EH40 sets an 8-hour time-weighted average of 0.05 mg/m³ for chromium (VI) compounds. As a carcinogen, exposure must also be reduced as far below the limit as reasonably practicable.
Can the hazard be removed permanently?
Yes. Substitution replaces chromate-forming insulation with alkaline-free materials, removing the hazard at source rather than managing it indefinitely.
Training and certification
Who is the training course for?
Site teams and duty-holders who need to recognise chromium (VI), understand the COSHH duty and act on it.
How is the course delivered?
It is online and self-paced. Login details are emailed to the nominated trainee on purchase.
What happens if someone fails the quiz?
The quiz must be passed at 100%, but retakes are unlimited, so the certificate reflects genuine competence.
What do trainees receive on passing?
A personalised PDF certificate, issued instantly, emailed and available to download.
