Loading unloading will take place through specified opening with the help of scissor lift within the cold storage. The capacity of the lift is 250 Kgs and its dead weight is about 300 Kgs Max. The total weight of the lift would be about 550Kgs at Maximum. Detail of scissor lift is as shown below:
4. Product will be stored in cylindrical containers stacked in SS racks of 1.5 mx2mx2.7m.Detail of rack is as follows.

A. Design parameters of clean rooms in the 1st floor
Specifications for clean room Class 1000 for Trace metal measurements in water samples
Clean room in the 1st floor
This area has to be partitioned into two so that one compartment/room can accommodate two units of fume hoods that we already have with us. The other compartment will be utilized for keeping instruments for trace metal analysis. In addition to these there should be an entrance room. The construction should be fully of PP/FRP material (PP is polypropylene and FRP is fiberglass reinforced plastic material).
The clean room should be underpositive air pressure. The filters used should be HEPA filters with efficiency to remove particles down to 0.3 micron from air/gas streams with efficiency exceeding 99.97%. The filter media should comprise of specially treated glass fiber of high quality cellulose and cellulose-glass fiber with varying degree of dust extraction. The return air should be picked up from the floor level through air risers; surface mounted on the clean room walls.
The blower used for the exhaust should be preferably non-metallic or epoxy coated. Provision of service doors in blowers and mixing box section wherever required and the doors and panels should be sealed with food grade rubber gasket in order to avoid air leakage. The inner part of the unit should be installed with 100% PPG stripes.
The paint wherever used should be epoxy.
There should be air cooling system in the room.
The clean room ceiling should have rigid structural support and suspension system in FRP sheets construction, supported by ‘T’ shape grid. Silicon caulking of joints should be provided to prevent induction of particles into the clean room and loss of design pressure temperature.
The other things we need in the clean room are clean benches, sink and shelf or rack. The sink should be non-metallic preferably PP material that can withstand strong acids. The clean benches are also preferred with same material.
The room should have inlet for gases: two each in both compartments/rooms. We would also like to put one Ultra filtration water system in the room where fume hoods will be placed. Depending upon the design of the room we can purchase the system. It would be advisable to keep gas cylinders mounted in the entrance room with good clamping system.
The door should be PP FRP double door glaze finish.
Entranceinto the trace metal clean room should be through a staging room or an ante area where researchers get suited up (bodysuits, gloves, boots,and face masks). This area is provided as a processing area for personnel, materials and equipment. The area should be able to store an adequate amount of gowning supplies. Also, if possible, the ante room/area should not be part of a high traffic area or corridor.
Finished surfaces, such as walls, floors, fixtures and ceilings, should be durable and smooth.
The best way to envision a well designed controlled environment is, with the exception of the air supply and exhaust, a room that is "waterproof." Any materials used in the construction of the controlled environment should have technical data available to verify their serviceability and whether they are appropriate for a specific application.
Air Showers should be an integral component of the modern clean room
Shoe Cleaners: House exhaust systems and stand-alone recirculating HEPA filtered units.
Sticky Mats: Disposable and washable mats.
Clean room Telephone: Flush or Surface mounted hands-free Class 1000 compatible telephone.
Clean room Vacuum: The portable vacuum system is specifically designed and packaged for use in clean rooms. It should have a four-stage filtration system.
Schematic drawings are enclosed herein for reference .However vendors are free to suggest their own details for achieving the design parameters.
Clean room facility to be provided is located in the newly constructed extension to biological oceanographic department distributed on two floors i.e. first and second floor.

• The clean room dimensions on second floor are 5.0 m x 5.10 m .This area has to be partitioned into two. The rough layout of the clean room is presented here but this may be modified in consultation with the architect.
• The taps sinks and drainage pipes should be strictly non-metallic. It should be of polypropylene plastic/ FRP. The clean bench should be of plastic polypropylene material which is extremely durable and non- corrosive thermoplastic, highly resistant to most acids, solvents, and other corrosives, polypropylene offers nonconductive properties and easy cleaning as well.
• The cabinets should also be polypropylene material and should be modular.
• The height from ground is approx. 0.85 m and table width 0.8m.
