[174], The rainfall pattern is influenced by monsoon winds from the Indian Ocean and Bay of Bengal. The lab specific information is incorporated into several sections of the LSM: chemical inventories, SOPs (Section 6 and Appendix D), training (Section 7) and laboratory-specific information listed at the front of the manual, including the lab floor plan,the name of the principle investigator, chemical hygiene officer, the room numbers and descriptions, and emergency information. [346][347] Corruption remains a problem in Sri Lanka, and there is little protection for those who stand up against corruption. 6-Up Labels.

If used above ground, the piping shall either be secured to prevent disengagement at the fitting or the piping system shall be so designed that any spill resulting from such disengagement could not unduly expose persons, important buildings or structures, and could be readily controlled by remote valves.
