FM heeft een aantal datasheets aangepast (“revision”). De belangrijkste heb ik voor jullie eruit gelicht.
De belangrijkste wijzigingen zijn omschreven. Kernwoorden zijn vetgedrukt.
| DS 1-2 Earthquakes | Interim revision. This revision primarily incorporates technical guidance for the expanded scope of equipment including the following items: • Raised access floors and supported equipment. • Transformers and battery installations. • HVAC and refrigeration equipment on structural floor. | |
| DS 1-15 Roof-Mounted Solar Photovoltaic Panels | Interim revision. Minor editorial changes were made. | |
| DS 4-9 Halocarbon and Inert Gas (Clean Agent) Fire Extinguishing Systems | Interim revision. The following changes were made: • Editorial change was made to Table 1 of Class C design concentration for FK-5-1-12. • The minimum design concentration percentage was revised to include the proper safety factor based upon the Class A minimum extinguishment concentration. | |
| DS 2-0 Installation Guidelines for Automatic Sprinklers | Interim revision. The following changes were made: • Figure 2.5.1.3.1 was modified to account for recent test results involving gravity heat/smoke vents. • Appendix A was updated to provide clarifying definitions for both gravity heat/smoke vents and mechanically operated smoke vents. | |
| DS 4-12 Foam Extinguishing Systems | Interim revision. Editorial change was made to Section 3.4.4.1.1 to include reference to the European Chemicals Agency (ECHA) proposal for a separate REACH restriction on PFAS in firefighting foams. | |
| DS 4-13 Oxygen Reduction Systems | Interim revision. The following changes were made: • Provided other options to maintaining the needed nitrogen concentration for 12 hours within a room/building/equipment enclosure due to loss of power. • Provided additional options for achieving N+1 nitrogen generator designs. • Provided additional information on where to provide O2 sensors and how many sensors are needed for much larger building volumes. • Provided additional information on O2 sensor maintenance and replacement schedules. | |
| DS 5-4 Transformers | Interim revision. Minor editorial changes were made. | |
| DS 5-33 Lithium-Ion Battery Energy Storage Systems (New title) | Interim revision. The following major changes were made: • Changed title to “Lithium-Ion Battery Energy Storage Systems.” • Revised separation distance recommendations for indoor and outdoor LIB-ESS. • Added recommendation for early intervention thermal runaway prevention. | |
| DS 7-11 Conveyors | Interim revision. Updated housekeeping guidance in Section 2.2.2.1. | |
| DS 7-15 Garages | Interim revision. Clarification was made in Section 1.0, Scope. | |
| DS 8-34 Protection for Automatic Storage and Retrieval Systems | Interim revision. Major changes include: • The scope of this data sheet was modified to indicate that it applies to material handling of small containers and small trays. • The generic term “horizontal-loading” was introduced to address both mini-load and shuttle type (i.e., shuttle) ASRS storage arrangements. • Protection guidelines of (1) closed-top containers stored directly on the rail supports of a shuttle ASRS and (2) closed-top storage maintained on trays within a shuttle or mini-load type ASRS referenced in FM Global Property Loss Prevention Data Sheet 8-9, Storage of Class 1, 2, 3, 4, and Plastic Commodities have now been added to this data sheet. | |
