Monitoring fire risk assessment

The fire risk assessment is not a one-off procedure. Construction sites are continually changing as work progresses. The site should be continually monitored to ensure that the existing fire safety arrangements and risk assessment remains realistic. The assessment should be reviewed frequently as fire significant changes take place. 

The records made of each fire risk assessment should be used as the basis for monitoring the effectiveness of the measures taken.

FIGURE 15.21 Using the Petrella plot for comprehensive and reasonable scientiflc assessment of flame retardancy by comparing different approaches, or by comparing the effects for different irradiations. THE stands for the Are load and PHRR/tig for the fire growth rate hence, the two most important fire risks are monitored at the same time. An ideal flame retardancy would decrease both hazards significantly as is the case for the combination of both flame retardants on the left (comparison of HIPS), HIPS/Pmd, HIPS/Mg(OH)2, and HIPS/Pmd/Mg(OH)2) and for low external heat flux on the right (comparison of PA 66-GF and PA 66-GF/Pred for different irradiations). 

The deca equivalent has not been banned in Emope. Widely used in televisions and other fire risk equipment as well as textiles, it has been subjected to almost a decade of investigation in Emope. Concern has been focused mainly on its environmental effects. The European Union Member States Competent Authorities has recently concluded that the risk assessment of this substance should be discontinued for lack of evidence, although a monitoring programme will address any environmental concerns, including emission levels. BSEF hopes that deca-BDE will be exempted from 2002/95/EC (the RoHS Directive) restrictions. PBBs were banned in the Directive 2003/11/EC.
