With health and safety becoming more of a day to day priority in the workplace, it is essential that employees have visibility of the correct health and safety procedures. Employers have a legal duty under the Health and Safety Information for Employees Regulations (HSIER) to display the approved HSE poster in a prominent position in each workplace that outlines British health and safety law. The 2009 poster replaces the version which was published in April 1999. The 1999 poster or leaflet must be replaced with the 2009 poster or leaflet no later than 5 April 2014. Each copy of the 2009 poster incorporates a unique, serial numbered hologram in the bottom right corner for authenticity. The Health and Safety Executive (HSE) is a non-departmental public body of the United Kingdom with its headquarters in Liverpool, England. It is the body responsible for the encouragement, regulation and enforcement of workplace health, safety and welfare, and for research into occupational risks in England, Wales and Scotland.
