Terms of Use

These terms govern your use of heirarc.com, operated by Heirarc Power System Studies ("Heirarc", "we"). By using the site you agree to them.

No engineering advice

Content on this site, including Industry News articles, is general information. It is not engineering advice for any specific facility and may not reflect the latest code or standard. Using the site, requesting a quote, or emailing us does not create a professional engineering relationship. Engineering services are provided only under a signed agreement, and deliverables are valid only when signed and sealed by a licensed Professional Engineer.

Free tools

Tools on the Tools page are free reference aids. They do not perform an engineering analysis, are provided "as is" without warranty of any kind, and must not be relied on to select personal protective equipment, set protective devices, or decide whether equipment is safe to work on. Those decisions require a current study for the specific equipment, prepared by a qualified engineer.

Limitation of liability

To the fullest extent permitted by law, Heirarc is not liable for any damages arising from use of this site, its content, or its free tools. This does not limit obligations under a signed engineering services agreement, which is governed by its own terms.

Intellectual property

Site content, tools, and branding belong to Heirarc. You may share links and quote brief excerpts with attribution. Do not copy or republish the site or its tools without permission.

Acceptable use

Do not misuse the site, including submitting false requests, attempting to access non-public areas, or interfering with its operation.
