Where can the manufacturer's emergency phone number be typically found in an MSDS?

The key idea is where a safety data sheet places essential contact information. The manufacturer's emergency phone number is part of the identifying details for the product and the supplier, so it lives in the section labeled Identification. This section is meant to tell you who made or supplied the chemical and how to reach them in an emergency, which is exactly what responders or site personnel need right away. Other sections serve different purposes: First Aid Measures tells you what to do for injuries, Hazards Identification explains risks and classifications, and Physical and Chemical Properties describes the substance’s characteristics. Those sections don’t provide the manufacturer’s contact information, which is why the emergency number is found in the identification section.
