DOT Division 1.5: Very Insensitive Substances

Division 1.5 is the DOT explosives division for very insensitive substances that have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of a fire changing to a detonation under normal transport conditions.

How it is defined

  • The material can still detonate if it is strongly initiated, so it is not a low-risk material.
  • Compatibility group D is typical for 1.5 blasting agents.
  • Segregation rules keep it away from detonators and other initiators.

Summary of 49 CFR Parts 171 to 180. The regulations and the Hazardous Materials Table (49 CFR 172.101) control any shipment.

Packing groups

None. Class 1 is assigned by division and compatibility group. How packing groups work.

Common examples

  • Blasting agents such as ammonium nitrate-fuel oil (ANFO) mixtures
  • Some bulk emulsion explosives

How it relates to GHS

Corresponds to the GHS explosives division 1.5.

DOT classes and GHS classes are assigned under different rules, so a product can have different severity labels in each. See also all GHS hazard classes.

Safe handling reminders

  • Never mix with fuels or contaminants outside of approved blending operations.
  • Store separately from detonators and boosters.
  • Follow the explosives licensing and storage rules.

Where to find it on an SDS

Section 14 will show Division 1.5, compatibility group D and a UN number. Look in Section 14: Transport information. Hazard classification for the workplace is in Section 2. You can also see how a UN number points to a response guide on the UN and NA numbers page.

Frequently asked questions

What is Division 1.5?

Division 1.5 covers very insensitive explosive substances that carry a mass explosion hazard but have very little chance of detonating from normal causes. Blasting agents are the standard example.
