SAFETY INFORMATION
GHS hazard statements and codes, safety precautions, risk codes and transportation information
HAZARD STATEMENTS
The Globally Harmonized System of and Labeling of Chemicals (GHS) designates standardized phrases, known as hazard statements, about the hazards of chemical substances and mixtures.The GHS designates the following elements for the labeling of containers:
- Hazard statement
- An identification of the product
- A signal word when necessary - either WARNING or DANGER
- The identity of the supplier
- Hazard Pictograms when necessary
Hazard statements are designated a code, starting with the letter H and followed by three numbers.
REGISTRY OF TOXIC EFFECTS OF CHEMICAL SUBSTANCES (RTECS)
Formerly known as the Toxic Substances List, the Registry of Toxic Effects of Chemical Substances (RTECS) is a database of toxicity information assembled from the open scientific literature. Toxicity information for over 150,000 chemical substances including: prescription and non-prescription drugs, food additives, pesticides, solvents, diluents, chemical wastes, fungicides, herbicides, reaction products of chemical waste, and substances used in both household and industrial situations are included. Additionally, toxic effects and general toxicology reviews, mutation, data on skin and/or eye irritation, reproductive consequences and tumorigenicity are presented. Federal standards and regulations, NIOSH recommended exposure limits and information on the activities of the EPA, NIOSH, NTP, and OSHA regarding the substance are also incorporated.
TRANSPORTATION INFORMATION
United Nations (UN) and North American (NA) Numbers are required for shipment of hazardous materials.
UN Numbers are four-digit numbers that range between 0000 and 3500 following the letters UN. Associated with each UN number is a hazard identifier, which encodes the general hazard class and subdivision (and, in the case of explosives, their compatibility group).
NA or DOT Numbers are often used when a UN Number is not assigned. This number is typically four digits that begin with the number 8 or 9 following the letters NA.
THE GERMAN WATER HAZARD CLASS (WGK)
The German Water Hazard Classes or WGK are numbers assigned by The German Federal Water Management Act. Substances are evaluated for negative influence on the physical, biological or chemical characteristics of water and then given one of the following WGK numbers:
- WGK nwg: Non-water polluting substance
- WGK 1: Slightly water polluting substance
- WGK 2: Water polluting substance
- WGK 3: Highly water polluting substance
