Point 6 of EN standard 14175-2 indicates that fume hoods must be made of materials resistant to MECHANICAL, CHEMICAL AND THERMAL FORCES AND MUST NOT BE EASILY COMBUSTIBLE. Due to the nature of the work usually carried out in a fume hood, there is a fire hazard which is the result of possible explosions or fires inside the apparatus. In prevision of these accidents, all our fume hoods have been designed to protect the user at all times by incorporating the highest number of operational and constructive safety measures possible.
AIRFLOW INDICATOR CONTROL
Point 8 of Standard EN 14175-2 requires all fume hoods to have an airflow gauge which unambiguously demonstrates the device is operating properly.This indicator must be easily verifiable and have visual and acoustic alarms to inform the user of the operational status of the fume hood. Our line of VA fume hoods has an SG AIR FLOW INDICATOR which visually controls and monitors the operational status of the extraction (1) whether there is a constant or variable airflow (2).It also features visual and acoustic indicators (3) which alert the operator on any possible anomalies in the fume hood that are due to a lack of extraction.The advisory and operational conditions can be programmed to specific user requirements by making simple changes in the software using the RS-232 connector (4).
An internal device set inside the cabin activates the alarm when the interior becomes overheated.If at any time during operation the interior temperature surpasses the established limit, the system automatically activates:
- The alarm light (5)
- The alarm bell (3)
- An alarm signal is sent to the central safety control system, if there is one.
- The exhaust function stops in order to prevent any fire from spreading. The exhaust stoppage occurs if the temperature reaches a 2nd programmed value.
COMPLETELY INCOMBUSTIBLE CONSTRUCTION
Flores Valles fume hoods have two safety barriers to prevent fires from spreading: INTERIOR CABIN BODY Built of 1.5-mm thick electro-galvanized steel in compliance with EN standard 10152, and coated in ADIPROL® (heat-cured resin with little cross-linking). This construction method provides high chemical resistance and a great contention capacity in the event of fire (M0 material), in addition to providing the fume hood with great durability.EXTERIOR BODY Built of 1- to 2-mm-thick DC.O1 cold-laminated steel, in compliance with standard 10027, and protected with an organic coating of epoxy-polyester resin.
The exterior shell forms a second safety barrier in event of fire or explosion. The block underneath the fume hood is also made of completely incombustible materials (M0).If too much pressure builds inside the fume hood as a result of an explosion, the expanding wave is efficiently discharged towards the exterior through the lighting housing located in the top panel.
