FSH/18/5 - Watermist systems

Sector: Construction

Categories: Waste. Equipment and installations. Disposal and treatment. | Fire protection. Other | Fire protection equipment | Cooking ranges, working tables, ovens and similar appliances | Fire Protection. General

Overview: Under the direction of FSH/18, will consdider developments in the emerging UK watermist fire fighting industry. It will address the needs for standardization in order to ensure effective and safe watermist firefighting systems can be specified and delivered through adoption of industry best practice and will also review and contribute to CEN Wtaermist standardization.
