The NAS411 Standard in a Nutshell

NAS411 is a National Aerospace Standards (NAS) to manage risks associated with hazardous materials (HAZMAT).

This standard stems from the Civil Aviation Environmental Committee. The aerospace industry commonly uses it for its services and its products as part of a management system. However, this standard can also serve as guidance in the production and manufacturing of various industrial sectors.

How to Implement a NAS411 Hazardous Materials Management Program (HMMP)?

To achieve a hazardous materials management program (HMMP) that follows the NAS411 principles in your organization, you will have to complete several milestones:

Defining the Hazardous Materials Management Program

Hazardous Materials Management Program HMMP

First of all, you need to confirm the scope of your HMMP. For example, is it going to cover every facility or only some departments at risk?

To determine the scope, you may consider:

  • The potential adverse impacts on people, the environment, and equipment;
  • the situations restricting the performance of services and products.

NAS411-1 and the HAZMAT List (HMTL)

Once the scope is defined, you can create the hazardous materials list that you will manage via your HMMP. 

Standard NAS411-1 is interrelated with NAS411. It provides a hazardous materials target list (HMTL). Listed HAZMAT are either:

  • Prohibited;
  • Restricted; or
  • Tracked.

The HMMP Plan


Per NAS411, the organization must have an HMMP plan, which must be part of the organization’s management system. Among other things, such a plan describes:

  • the scope;
  • the organization structure in charge of the HMMP;
  • the HMTL with quantities and recordings, such as the suppliers’ safety data sheets (SDS);
  • the Environment, Safety, and Occupational Health (ESOH) risk assessment considering the substances hazardous properties;
  • the elimination, minimization, and management of the HMTL;
  • the HAZMAT alternative assessment, with cost, schedule, and performance indicators of risk mitigation;
  • the HAZMAT approval and procedure;
  • the requirements to subcontractors and suppliers, relevant to HAZMAT management.

The HMMP Report

Once planned, the organization will execute the HMMP. A report will reflect the actions and their outcome, including:


  • The identification of HAZMAT, and associated documents in appendix A of NAS411, such as SDS, declarations (like RoHSREACH, or California Prop. 65), drawings, etc.
  • Prohibited HAZMAT approval request, along with the risk assessments;
  • Subcontractors and suppliers relevant information.
