Abstract:
This study project is aimed to develop a guideline for improving the pesticide storage room at
Division of Preventive Medicine, Directorate of Medical Services, RTAF. Due to the extensive use
of the pesticide storage room with the size of 5X8X4 m', the air ventilation and the lighting system
are now deteriorated while a chemical storage is also disorganized. Therefore, suggestions to
improve the indispensable facilities for the existing pesticide storage room including ventilation,
lighting, drainage, fire extinguisher and safety sign in order to comply with the UN Storage of
Hazardous Material Standard, the Fire Protection Standard of the Engineering Institute of Thailand,
and the Building Control Act RE. 2522, were proposed. From the chemical information of the
ending inventory and the procurement record during 2004 to 2007, most chemicals either in the
form of solid, liquid, or gas could be classified in the groups of pyrethrum and pyrethroids. The
storage quantity for each chemical was estimated to be 1.5 times of the summation of the remaining
chemical at the end of 2007 and the average annual procurement. If the existing pesticide storage
room is going to be continually used, it is suggested that each chemical should be placed on a
separated wooden pallet of 1.2xO.8 m2 size and piled up to not over 1.5 m height. Moreover, the
chemicals should be separately stored into 3 zones according to their states, i.e., solid, liquid, and
gas. On the other hand, if a new pesticide storage room is going to be built, it should have at least
35 m2 area in which the size of 5X7 m2 was used as a demonstrative case. In addition, all essential
major structures and technical facilities for safety practice were also proposed to meet the
mentioned regulation. Lastly, an instruction manual for operation and maintenance the pesticide
storage room was also prepared to be used as a guideline for safety measures.
