The service

Sierra Tango Safety provides a subscription-based practice question bank for the NEBOSH HSE Certificate in Process Safety Management. It is an independent study aid and is not affiliated with, endorsed by, or connected to NEBOSH or the Health and Safety Executive. Questions are original practice items written to reflect the published syllabus; they are not past papers.

No guarantee of results

Using this question bank does not guarantee a pass. Nothing on this site constitutes professional health and safety advice for a specific workplace.

Accounts

You are responsible for keeping your login details secure. Accounts are for individual use; sharing access or redistributing question content is not permitted.

Subscriptions and billing

Subscriptions renew automatically at the price shown on the pricing page until cancelled. You may cancel at any time from your account; access continues until the end of the paid period unless a refund is issued, in which case access ends immediately.

Intellectual property

All question content, explanations and site material remain the property of Sierra Tango Safety and may not be copied, resold or republished.

Changes

We may update these terms and will publish any changes on this page.
