Hazard Labelling \u2013 Questions and Answers on Safe Chemical Handling<\/h1><\/h1><\/div><\/div><\/div><\/div>What is Hazard Labelling?<\/h2><\/div>Hazard labelling indicates whether a product may be dangerous to health, the environment, or safety.
\nLabels follow the EU <\/strong>CLP Regulation (EU 1272\/2008)<\/strong><\/a>, and are designed to make risks easy to understand.<\/p>\nA proper label includes:<\/p>\n
\n- Hazard pictogram (symbol)<\/li>\n
- Signal word \u2013 \u201cDanger\u201d or \u201cWarning\u201d<\/li>\n
- H- and P-statements \u2013 describing risks and safety measures<\/li>\n
- Product identification and contact information<\/li>\n<\/ul>\n
In short: hazard labelling tells you what you need to know before using a product.<\/p>\n<\/div>

Which regulations apply?<\/h3>\n
Across Norway and the EU, the following apply:<\/p>\n
\n- CLP Regulation (EU 1272\/2008)<\/strong><\/a> \u2013 classification and labelling<\/li>\n
- REACH Regulation<\/strong><\/a> \u2013 registration and safety information on chemicals<\/li>\n
- National HSE regulations<\/strong><\/a> \u2013 requirements for chemical inventories, training, and risk assessment<\/li>\n<\/ul>\n
Manufacturers are responsible for labelling and updating products correctly.
\nEmployers must ensure that workers understand the symbols, use proper <\/strong>PPE<\/a><\/strong>, and have access to <\/strong>Safety Data Sheets (SDS).<\/a><\/strong><\/p>\n<\/div>How to Ensure Correct Hazard Labelling in Practice<\/h3><\/h3><\/div>1.
