Helsefarlige

Helsefarlige is a term used to describe substances or agents that can cause harm to human health through exposure. The designation is applied to chemicals, mixtures, and sometimes biological or physical agents when contact, inhalation, ingestion, or absorption can lead to adverse health effects. Health hazards can be acute, such as irritation or poisoning, or chronic, including cancer, reproductive toxicity, or organ damage.

Examples of helsefarlige stoffer include asbestos, benzene, formaldehyde, silica dust, lead and other heavy metals, certain solvents, and some pesticides. The risks depend on factors such as the amount, concentration, duration of exposure, and the route of exposure. Protection typically involves controlling exposure, using appropriate handling procedures, and minimizing contact.

Regulatory context and risk management: In many countries, including Norway, the classification and labeling of helsefarlige substances follow international systems such as the Globally Harmonized System of Classification and Labelling (GHS) and its national implementations (for example CLP in the European Union). Substances classified as health hazards are labeled accordingly and accompanied by Safety Data Sheets (Sikkerhetsdatablad) that detail hazards, first aid measures, storage, disposal, and required controls. Employers have a duty to perform risk assessments, implement control measures (substitution where possible, engineering controls, ventilation), and provide personal protective equipment when necessary. Workers should receive training on safe handling, exposure limits, and emergency procedures.

The term helsefarlige is commonly used in occupational safety, product labeling, and public health communications to indicate health-related hazards and guide precautionary actions.
