While a Public Address System is used to convey general information or paging, they often double-up as a Voice Alarm System, used to convey emergency or safety information, such as “beware of unattended packages” or evacuation guidance in emergencies. Voice Alarm Systems must be designed and perform to the minimum requirements set out in British Standards.

Work at height, including the erection of scaffolding, is a hazardous activity, and regrettably, injuries occur during scaffolding work. To provide guidance in preventing this, the NASC issued a pocket booklet, with the current (as of 2022) version being titled ‘SG4:22 Preventing Falls in Scaffolding Operations’.

Do You Need to High Speed Test Generator Rotors?

The subject of high-speed balancing generator rotors can be contentious, and the practice varies across the world. In Europe, with relatively easy access to high-speed test facilities, the default position is generally to carry out the testing. However, in Southeast Asia, Africa and South America, where there are fewer (if any) facilities, a risk-based approach is taken more often; this approach does not include high-speed testing

We discuss the regulatory requirements when using a wheelchair as a vehicle seat, together with some of the technical factors involved in the event of a collision.

Investigating The Causes Of Vehicle Fires

Keeping the vehicle’s tax up to date
Obtaining a current MOT certificate
Maintaining the roadworthy condition of a vehicle
Having a minimum third-party insurance that covers use of the vehicle

Contamination: An Interruption That Means Business

Even a small fire can cause smoke contamination throughout a much larger area, including as the result of spread through sealed doors in some circumstances. Water damage related to fire-fighting activities can also cause mould to contaminate and damage stock as well as the building structure. Hawkins has investigated many fires from small to large scale incidents, which have started in one building and spread to affect neighbouring businesses.
