Mechanical Valve Safety

Employee welfare within a manufacturing or engineering environment is a primary concern for employers. All workers should expect to be able to carry out their work in a safe manner that has no negative effect on their health and wellbeing. Many organisations even believe that their working environment should be superior to others, making it a competitive aspect when recruiting staff. Health and safety in the workplace is about measures designed to ensure the health and safety of employees, visitors, the general public and the environment, who can be affected by workplace activities. Health and safety is controlled largely by legislation and regulations and the law is continually being revised and updated. It is important that organisations are aware of these changes and keep up to date with developments. Lockout Tagout is a safe way of ensuring employee safety when working on isolated machinery, and ensuring organisations can follow legislation.
