Hazard statement

Written by Steve Hudgik May 2013


A "hazard statement" is part of the information that is required by the OSHA Hazard Communication Standard (HCS) to be included on Globally Harmonized System (GHS) labels.

Hazard statements are predetermined, assigned, standardized phrases that describe the hazard(s) of a material based on its hazard classification. For any material that has one or more hazards, the appropriate hazard statement for each GHS hazard must be included on the GHS label.

There is a specific phrase assigned to each hazard category. That phrase describes the nature of the hazard. Examples of hazard statements include:

  • Harmful if swallowed
  • Highly flammable liquid and vapor
  • Fatal if swallowed
  • Harmful to aquatic life

Other Information on GHS Labels:

In addition to hazard statements, other information that is required on GHS labels includes:

Hazard Statement – GHS Codes

Each hazard statement has a designated code associated with it. The code should never be used on a GHS label. The code is only used for reference purposes. For example, the code helps when the hazard statement needs to be translated to another language. Only the hazard statement phrase(s) should appear on GHS labels.

Each hazard statement code starts with the letter "H" followed by a three-digit number. The numbers are grouped based on the three categories of hazard statements:

  1. Physical Hazards (numbers are in the 200's)
  2. Health Hazards (numbers are in the 300's)
  3. Environmental Hazards (numbers are in the 400's)

Hazard Statement vs Precautionary Statement

A precautionary statement is also included on a GHS label, and should not be confused with the hazard statement. The precautionary statement is used to give recommended measures used to minimize or prevent adverse effects resulting from:

  • Exposure to the hazardous material
  • Improper storage
  • Improper handling

There are four types of precautionary statements:

  • Prevention (to minimize exposure)
  • Response (in case of accidental spillage, exposure emergency response, or first-aid)
  • Storage
  • Disposal

An example of a precautionary statement would be:

Do not breathe dust/fume/gas/mist/vapors/spray. Get medical advice/attention if you feel unwell. Dispose of contents/container in accordance with local/regional/national and international regulations.

Other examples of precautionary statements include:

  • Keep away from heat/sparks/open flame/hot surfaces - No Smoking
  • Keep/Store away from clothing and combustible materials
  • Keep only in original container

Other GHS Label Elements

GHS labels must include other information in addition to the hazard statement. Other GHS label elements include pictograms, a product identifier, signal word, and supplier identification. A quick look GHS training terms:

  • Pictograms: There are nine predefined pictograms that are used on GHS labels. They consist of a symbol inside a diamond that has a red border. Each pictogram identifies a hazard class such as acute toxicity or eye/skin irritation.
  • Product identifier: This is a name (or number) that is a unique way to identify the chemical. This can be the chemical name, code number, or batch number. The manufacturer, importer or distributor can decide the appropriate product identifier.  For mixtures the label should identify the ingredients responsible for the hazards characteristics of the mixture.
  • Signal word: The signal word indicates the relative severity of the hazard. There are only two signal words used, “Danger” and “Warning.” Danger is used for severe hazards that represent risk to life.  Warning is used for the less severe hazards. Only one signal word will be on a label no matter how many hazards a chemical may have. Some categories of hazards and unclassified products require neither signal words nor pictograms.
  • Supplier identification: This is the name, address and telephone number of the manufacturer, importer, or supplier of the substance.
