Your statutory cancellation rights. Under the European Union (Consumer Information, Cancellation and Other Rights) Regulations 2013 (S.I. No. 484 of 2013) you normally have 14 days to withdraw from a distance contract.

Major accident hazards in Ireland are governed by the Chemicals Act (Control of Major Accident Hazards Involving Dangerous Substances) Regulations 2015, S.I. No. 209 of 2015, which implement the Seveso III Directive. The HSA is the central competent authority.
Whether a site is in scope — and at which tier — depends on the quantities of dangerous substances present, measured against the thresholds in the Regulations.
This course explains the framework. Site-specific roles in the safety report or emergency plan need training on your own establishment’s procedures.
