Components of P&ID
•Mechanical machinery named and listed numerically
•All valves and their identifications
•Process piping, sizes and identification
•Vents, drain, special fittings, sampling lines, reducers, increasers and swagger under miscellaneous items
•Permanent start-up, flush edges and flow directions
•Interconnections reference, control inputs, and output interlock
•Seismic category and annunciation inputs
•Computer control system input
•Vendor and contractor interfaces
•Identifications for outsourced components and subsystems
•The estimated physical sequence of the equipment and its rating or capability.
•Different symbols are used for different type of valve, equipment, piping, vessel ,Heat exchanger, pump, valve.
Unit Process
In such processes, by combination (chemical reaction) of two or more chemicals, a new product (compound) is formed. It indicates a chemical change.
Unit Operations
In such operations, there is no chemical reaction to form a new product. It indicates no chemical change but mechanical or physical change like distillation, cutting, heating, cooling, drying, mixing grinding, washing, packing, transferring, filtering, handling, radiation etc.

Sampling techniques for toxic & flammable chemicals
Sampling can be done in three ways:-
a) Personal Air Sampling
b) Workplace Air Sampling
c) Ambient Air Sampling
There are two methods of sampling air borne particles :-
1) Filtrations Sampling
2) Use of Direct Reading Equipment
Personal Dust Sampler
Types of filters & applications
Sampling Train
