Warning systems Protection Train

Early evidence suggests that the accident would have been prevented by the installation and correct operation of a Train Protection Warning System (TPWS)... 

Copyright 2001, National Fire Protection Association, Quincy, MA 02269. This warning system is intended to be interpreted and applied only by properly trained individuals to identify fire, health, and reactivity hazards of chemicals. The user is referred to a certain limited number of chemicals with recommended classifications in NFPA 49 and NFPA 325, which would be used as a guideline only. Whether the chemicals are classified by NFPA or not, anyone using the 704 systems to classify chemicals does so at their own risk. 

Engineering design should strive for elimination of hazards. Only when elimination, substitution, or engineering controls are not feasible should rehance on physical barriers, warning systems, training, and personal protective equipment be considered.

To offset this, U.S. chemical/biological (CB) defense materiel must not only provide a protective system equivalent to or better than that of any potential enemy but the physiological and logistics burdens must be such as to permit long-term use. To cope with the hazards of any potential CB-threat environment requires the development of an integrated CB defense system. This system must contain items for individual protection, collective protection, decontamination, warning and detection, and safe devices and concepts to achieve realistic training. 

Annex II to directive 1999/92/EC describes additional minimum requirements, which comprise organizational measures (i.e. written instructions, training of workers, a system of permits to work, warning signs) and criteria for the selection of technical equipment and protective systems, depending on the classification of zones.
