Chemicals known, presumed, or suspected to have adverse effects on the sexual function and fertility of adults or the development of offspring are considered reproductive toxicants.

With our 22-page guide, you will be able to classify these substances, evaluate scientific studies using the weight of evidence approach, and determine which label to use.

Specific Target Organ Toxicity, an umbrella term encompassing the non-lethal effects (targeting specific organs) that are not covered by the other Purple Book Health Hazards, can be hard to identify.

Read our comprehensive guide for all the classification principles and guidance values required to classify substances leading to health hazards after single exposure.

Specific Target Organ Toxicity, an umbrella term encompassing the non-lethal effects (targeting specific organs) that are not covered by the other Purple Book Health Hazards, can be hard to identify.

A wide variety of chemical substances may produce changes in human eyes accidentally exposed to them, up to and including serious, not fully reversible physical decay in a person's vision.

If you work with Safety Data Sheets, our 24-page guide will save you time and money and ensure you accurately classify eye damaging and eye irritating substances.

While the GHS and CLP group all types of toxic effects on aquatic ecosystems under a single Aquatic Toxicity hazard class, we have separated them into two individual eBooks for ease of classification.

This A to Z guide is 30 pages long and covers everything there is to know about short-term, acute aquatic toxicity classification for hazardous substances and mixtures.

While the GHS and CLP group all types of toxic effects on aquatic ecosystems under a single Aquatic Toxicity hazard class, we have separated them into two individual eBooks for ease of classification.

This A to Z guide is 34 pages long and covers everything there is to know about long-term, chronic aquatic toxicity classification for hazardous substances and mixtures.

Substances and mixtures with flash points at or below 93 degrees Celsius may have to be classified as flammable liquids. Determining the flash point and which classification are relevant, however, is a more complicated process.

Read our 17-page, straight-to-the-point guide written by ERA experts for all the information you need to identify and classify flammable liquids.
