Hazardous materials

Hazardous materials are substances or mixtures that present a chemical, physical or biological risk, e.g. are explosive, toxic, flammable, corrosive or carcinogenic.  The hazard potential of a material is usually indicated by a globally harmonised system of symbols for hazardous materials plus additional information.

Businesses that work with hazardous materials or produce such materials must comply with the statutory framework of the Hazardous Substances Ordinance. Employers are obligated to take suitable measure to protect their employees from any potential harm that could be caused by exposure to the hazardous materials stored, produced or used in the company. These can include, for example, protective gear, exposure limits in the workplace, extraction units or setting up special hazard zones. Additionally, any risk to the environment, water and soil must be avoided. The general maxim is: avoid, isolate, protect.

Once a hazardous material is transported it is defined as “Hazardous Goods” and must be transported according to international regulations for hazardous goods.

Companies that are subject to compliance with Hazardous Substances Ordinance must document and assess any risks associated with the hazardous substances they work with. As a rule, this task will be handled by an in internal or external hazardous materials officer. All employees who handle hazardous materials must have the appropriate training.
