The Employers' Liability (Compulsory Insurance) Act and the Health & Safety at Work Act are both there to protect your staff from accident, injury or abuse. While they are at work, your staff's welfare is your responsbility, but by installing security equipment you can help to protect them.
As an employer, you should carry out a risk assessment and take practical measures to protect employees from injury and report accidents and incidents.
By integrating access control with intruder detection and CCTV systems, you will be able to monitor incidents and verify what happened. These measures can support your responsibilities with regards to the Health & Safety at Work Act and the Employers' Liability Act, but can also reduce insurance premiums.
