Final answer:
Material safety data sheets provide a wide range of safety information but do not commonly include the manufacturer's contact information, which is typically found on the product label or the company website.
Step-by-step explanation:
Material safety data sheets (MSDS) are essential resources that provide critical information for safe handling and use of chemicals. They contain a range of information, including the chemical composition of the substance, its physical and chemical properties, first aid measures in case of exposure, and various other safety-related details. However, the MSDS does not include the manufacturer's contact information. This specific detail is often found on the product label or company's website, rather than in the MSDS itself. It is important to consult these data sheets before working with any new chemical and to understand the proper disposal methods to protect yourself and the environment.
