What our customers say

Frequently asked questions

What is the 24-hour emergency response phone number required by DOT?

DOT regulation 49 CFR 172.604 requires a 24-hour emergency response phone number on hazmat shipping papers, monitored at all times by someone who knows the product and its emergency procedures. Hazmat Line is how shippers meet that requirement: our specialists answer your dedicated line around the clock, with your SDSs on screen, for all 9 hazard classes and every mode of transport.

Is a hazmat emergency phone number required on shipping papers and SDS?

Yes. A hazmat emergency phone number is required on shipping papers under DOT 49 CFR 172.604 and in Section 1 of every SDS under OSHA HazCom. The number must be answered 24 hours a day while your product is in transit. Hazmat Line gives you one dedicated number that is valid in both places, in the US and wherever your products ship.

Can I use Hazmat Line as the SDS emergency phone number in Section 1?

Yes. Hazmat Line is designed to be the SDS emergency phone number in Section 1. You upload your SDSs in bulk, we standardize and index them, and your dedicated number becomes valid on every SDS, shipping paper and label. When the line rings, our specialists already have your documents on screen and respond immediately.

How much does a 24-hour hazmat emergency phone number cost?

A 24-hour hazmat emergency phone number from Hazmat Line starts at $599 per year for North America, with flat pricing: unlimited SDSs, affiliates and emergency contacts, and no extra charges per zone, shipment or document. Many providers charge extra for each of these items. International and global plans are available, plus one-time shipment coverage from $185.

How quickly can I get a 24 hour hazmat number?

You can get a 24 hour hazmat number the same day. Sign-up takes about five minutes online: choose your coverage and your account is active the moment you receive our onboarding email with your dedicated number, ready for your shipping papers, SDSs and labels. From there, just send us your SDSs in bulk, with no renaming needed.

What happens when someone calls my hazmat emergency number?

Because the number is dedicated to your company, we know which account is impacted the moment our phone rings, with no time lost on identification. A live hazmat specialist answers with your SDSs on screen and guides the response, prioritizing people, environment and property, in that order. Afterwards you receive a post-incident report with root-cause analysis.

Is a hazmat hotline the same as an emergency response number?

In practice, yes. Hazmat hotline, emergency response number and ERI telephone number all refer to the 24-hour number required by DOT on shipping papers and by OSHA in SDS Section 1. What matters is that the line is monitored at all times by someone who knows your products. Hazmat Line is that hotline, answered by live specialists on a line dedicated to your company.

What does a hazmat emergency response company do?

A hazmat emergency response company provides the 24-hour number your documents require and answers it with trained specialists during chemical incidents. Hazmat Line also works for you the rest of the year: we manage your SDS library, take carrier and audit calls, run drill calls to test readiness, answer regulatory questions through our helpdesk and document every incident with a full report.

What is a chemical emergency response phone service?

A chemical emergency response service connects anyone involved in a chemical incident, often a first responder reading your shipping papers or SDS, to specialists who know the product and how to handle it. The service provides immediate guidance on containment, health risks and cleanup, with medical and toxicology backup. Hazmat Line provides this service 24/7 in 220+ languages.

Who needs a hazmat emergency response number?

Any company that ships, stores or manufactures hazardous materials usually needs a hazmat emergency response number. Chemicals, paints and solvents, lithium batteries, propane and gases, fuels, cosmetics and aerosols, and hazardous waste are just a few examples. If your product requires shipping papers, an SDS or hazmat labels, chances are you need a 24-hour emergency response number, and carriers check for it before accepting your freight.
