Understanding HMIS: Hazardous Materials Labeling for Workplace Safety

The Hazardous Materials Identification System (HMIS) refers to a labeling system for hazardous materials developed by the National Paint &Coatings Association (NPCA). Companies use HMIS to inform workers of potential dangers.

Features

• HMIS labels provide separate numerical ratings for the health, flammability and physical hazard dangers of a chemical. Icons illustrate the specific type of danger, such as "explosive." The labels also identify recommended personal protective equipment (PPE), such as protective gloves.

Considerations

• Using HMIS complies with the Occupational Safety and Health Administration (OSHA) requirement that employers inform employees of any dangers at work. However, OSHA does not specifically require HMIS; other labeling systems are also acceptable.

Misconceptions

• HMIS and the Workplace Hazardous Materials Information System (WHMIS) are not related. The WHMIS refers to Canada's national system for safely managing hazardous materials.
