If your Health and Safety Poster looks like this then you will need to change them by 5th April 2014.
The Health & Safety Executive (HSE) first introduced the Health and Safety Law poster and leaflet in 1999. Under the Health and Safety information for Employees Regulations (HSIER) employers are required to either display the poster in a prominent location or provide each employee with the leaflet.
In 2009 the HSE introduced an updated, simpler version of the Health and Safety Law poster. In order to minimise the impact on organisations the HSE provided a five year transition period meaning that employers have until 5th April 2014 to replace the poster or leaflets with the new version.It is recommended that all employers update their poster and leaflets to the new versions immediately to avoid missing the deadline.
